i have a video thats in 720p. its avi which the n1 couldnt play so i renamed it as an mp4 like the other movies on my phone but it still wont play, the phone "cannot play this video"
I use doubletwist but it wont sync this video so i had to just click and drag from the folder to the sdcard
Is the problem that the n1 cant playback 720p? Am I not transferring the file properly? Because i was under the impression it would play 720p...Ive had three android phones and trying to play videos on them has always been like flapping my arms to fly, it never works and i feel stupid for trying...thanks for any help
I'm no expert, but you can't just rename a file to encode it in a different format. I don't know what double twist is, so can't help there.
Android hasn't been good for video playback, but all my videos that I encoded down for my Hero play much better on the N1.
The fact it wont play the 720p video files you put on there doesn't meen it can't, it just means you need to encode them into a format that the N1 likes.
I think the biggest problem is the amount of data the video uses per second compared to the amount of data the N1 can get off your SD card. Is it class 6?

I know this is VERYYYYYYYYYYYY irrelevant, but in your sig, it says "HTC Nexus One", where as the HTC codename(?) for the N1 is the "HTC Passion", Nexus One is it's Google branded name.. hence "Google Nexus One".
I hate calling people out on stuff like this, because it is a possibility that I could easily be wrong.. but it is something that kinda irritated me lol >.> and please don't reply back harshly.. I just had to say it ~.~ but you probably already know

The problem is the video is in the wrong format and the Nexus One doesn't have the proper codec. No you can't add codecs to the Nexus One. You will have to find software to convert it into a format it can recognize.
The supported video codecs for the Nexus One are on the Google Nexus One website.

Um.. you do know that N1 and the Passion are the same device, HTC first gives their own personal code names (from my understanding) to devices they create. I'm assuming whatever company asked for them to make the device then gets to rename it, or just keep the name (like the HTC Hero).
For example(s) the HTC Dream, is the G1, the HTC Sapphire, is the MyTouch. The HTC Passion, is the N1.
And myself I don't see anything wrong with saying HTC G1 either.
I understand your point, I just think mine is an HTC device that people call the Nexus One, so it's an HTC Nexus One...
I also have in my sig HTC Universal, wasn't that called the JasJar by HTC?
Anyway, we'er going way off topic here.
Staying on topic, in my understanding android by default cannot play .avi files. As AndyCr15 mentioned, you can't just rename a file and expect it to magically reencode itself. Just like how I can change the Ford badge of my Ford Focus into a Porche badge doesn't really make it a real Porshe does it?
You'll have to get yourself a video file converter and re-encode it to the approriate format.
^what they said. it's done in the wrong codec. there are avi files it will play, i believe, but it can't do divx or xvid right now encoded avi files. you need to find an h.264 something encoded avi.
doubletwist 'should' be able to do conversions for you. but, it takes forever and a day. probably faster to do it with ffmpeg. google for instructions
Archos 5 android internet tablet has the best media player but i don't know if anyone can extract it and make it work on N1.
you can download the firmware off their site
I already posted a while back about it...
It plays pretty much every video/audio format and does it perfect ...even plays 720p MKV
and even plays youtube @ 720
The archos has lower specs

Use handbrake to transcode your videos to mp4.
Just use the iphone profile, but make sure to change video resolution since iphone screen is smaller.

He's is talking about 720p even if you try to play an 720p Mp4 it wont play
o rly?
I reencoded the shuttle video from youtube in 720p and it plays without a hitch. (its already in .mp4 container on youtube, but still needs to be encoded)
1080p wont play though
yea i take that back think something was wrong with the mp4 vid i was using all i got was sound no vid at just re encoded wall-E 720 and plays fine
um guys. I hate to break it to you, but seeing how the screen resolution of the nexus one is 800x480, it is very fundamentally incapable of displaying 720 lines of vertical resolution.
Sure, you may have a video that is 1280x720, and the nexus one may play it, but it's scaled.
It's like hooking up a 15 inch lcd monitor to your computer and watching a video whos resolutions is 1920x1080, you can't say you're watching it in HD, because your display doesn't support an HD format.
that actually made sense.

@kyleroden — we kind of realize it will be downscaled to fit the screen
but if you dont feel like transcoding (which takes time) and have enough free space on the sd card, why not leave the vid as is?

It shouldn't be that hard if people can rip the Nemo Player from the Acer Liquid.
Think the reason why many 720p mp4 files won't play on the nexus one (or even iphone) depends on what encoding profile was used to encode the stream. The 3 mainly used encoding profiles are "baseline", "main" and "high". Anyone worth half their salt would encode 720p material in the "high" profile since is supports more bells and whistles like b-frames etc. and is normally intended to be played on a HD screen/TV with a more powerful player/decoder/PC etc.
The majority of mobile players don't really support the "high" profile since it requires more processing power to decode compared to "baseline". So chances are most 720p and higher materials need re-encoding for it to play unfortunately. Well since you are gonna transcode the stuff anyways you might as well set it at the correct resolution since the encoder software is going to a much better job scaling than on-the-fly scaling on the nexus one.
So is it a codec issue or a hardware limitation? I was expecting a 1GHz Snapdragon to be capable of playing back 720p h264 videos.. Yes I know the N1 doesn't have a 720p display but it would be convenient if transcoding videos weren't necessary..
OK, I am retiring my iPod Touch for ripping movies to take with me on trips, to watch either on the phone or with the HDMI output. That said, what resolution should I rip DVD's to so that they look good on the phone and on an HDTV using HDMI output? I read that 1280x720 is 720P, but my test showed that the movie played fine on the phone, but looked like a 4:3 movie when I played it on my HDTV. Any comments/suggestions/experience is greatly appreciated (I *really* want to be rid of my Touch...LOL).

How are you going to rip a DVD to 1280x720p when DVD's native res is 720x480 ntsc and 720x576 pal?
I'd say to rip your dvd's to 720x480 MP4 using Handbrake if you like free solutions or my favourite for-pay dvd ripper of choice is Win X Dvd Ripper. Look them both up.

You can use Daniusoft DVD Ripper. It will put the movie straight to your SD card and you can manually choose the res, fps, and a lot more.
It's really nice.
http://www.daniusoft.com/dvd-ripper.html
I would recommend ether the danusoft or cucusoft DVD rippers. CucuSoft has a vary of options that you can choose from. They go from little nanos to apple TV resolutions. You can of course by their full package but you can always save a buck or 2 by getting the one your need.
Here is a link: http://www.cucusoft.com/download.aspx
Go with Handbrake, an oldie but goodie. Just make sure you encode as MPEG4 and not h.264, as the native video player on the EVO can't handle h.264.
Use most of the default options unless you know what you're doing, or have read through the help page for Handbrake.
Personally, for quality I just shoot for a target size instead of a specific bitrate. For 90-120 minutes of film, 700-800 MB is usually good enough for viewing on the EVO's screen (yes, I've tested).
For Avatar, I set it to 1500 MB as it's a long flick.

Your smoking crack the EVO plays x.264.
Yes and no... evo will play h264's baseline profile, but not main and high profiles
It's still x.264 that's what I'm saying its easy too just select the iphone preset change the width to 800 check keep aspect ratio and change the extension to mp4 for some reason it does a m4v extension.
uh, thanks

Thank you for the kind correction
Nonetheless, for playing ripped movies on the EVO, I'd still recommend mpeg4 as opposed to h.264, if only because the encoding job is much quicker.

as long as there aren't hundreds of posts about it in this thread i think its ok to ask again. settings to encode for the evo may be different for the hero or mytouch. personally i use SUPER and use the ipod settings. sometimes ill adjust to taste. for real video watching i use my archos player no encoding needed.
Follow these instructions for nice looking videos.

Has any body tried to load a movie on there's yet?
I tried last night and because the file was like 5 gig it wouldn't let me copy to either the phone or the sd card.
Any body else got any input?
The filesystem is limited to 4gb files. I did try two videos, both 720p mkvs, worked flawlessly, if a little fuzzy. I am guessing its the rescaling effect.
Haven't tried 1080p as I don't see the point, but that's just me (1024x600 screen).
Gonna convert some vids to the native res and see how they look.
Yeah - Thats pretty much what I thought just wanted to double check. All my 720 films are over 4 gig
What about yours?
Have you converted and compressed them to make them smaller? If so which programme did you use?
Thanks in advance
720p TV programs are about 1.4GB. Samsung isn't limiting you, the FAT filesystem is limiting you.

Oh yeah - silly me,
Still though its not ideal
I put a couple of tv shows on there (South Park, Walking Dead, Ugly Americans). Max size was like 2.2GB.
I am converting them now to 1024x600 (should be 1024x576, but I figured the ever so slight difference should be ok)
However, I am at work now so I'll have to wait for a bit before I can check.
What programme do you use?
Try MKV2VOB. IT will change the files to AVI if you wish and maintain quality (or compress) as you wish. It also has within settings the ability to break up the files so that they don't exceed 4gbs for FAT32 formatted drives.... (Like what the PS3 needs )

Excellent. gonna give this a try when I get home.
I use mediacoder, works rather well for me, probably also has some setting to break the files up.
I got impatient, so I converted one file, South Park, from 720p mkv to 600p mp4, variable bitrate quality 50, came in at 61mb (lol) and yeah, sftp'd that sucker down, stuck it on and I have to say, looks good.
I am now gonna try something less easy (Walking Dead). It comes in to almost 600mb (from 2.2gb) so lets see how that looks. Will take a bit to d/l though.
Or I could just wait to get home.....but it's not like I have to watch the download take place.

Im gonna do abit of downloading an covering later on to see what gets the best results. I think Samsung should have brought there own converter out specifically for the tab that would have been nice.

Yeah, the original was ac3. It always is a bit soft to allow for dynamic range. I will make a note to bump up the gain for my future encodes.
Come on kids. The tab has a screen suited for 480p. Anything higher than 600 pixels will simply be bigger than the screen.
When you use the HDMI dock, however, it should play xvid @1080p on your tv.

480 <- 600 -> 720
Either will get scaled (up or down). Also cool how they are both the same distance from each other (120 lines).
Personally, I'd rather have MORE info and scale it down than less and scale it up.
Plus I also said that 1080p is massive overkill. 720p works nicely, though reformatted for 600p is smoother (less ghosting of movement to my eyes).
YMMV
so is AC3 working fine, I dont want to recode all the TV programmes. If it can play mkv 720p AC3 then Im happy. I know up until recently it couldnt do mult-channel audio, wether it be 720p or 1080p
yes, ac3 works fine for me.
there should be an easier solution to watch 720p movies. Is it not possible to simply split the movie in 2 parts? There should be some mkv-split program out there, that does not need to recode, just create new headers...
(so far I am watching tv shows, and those files are 1gb)
Mkvtoolnix will do it in seconds on windows.
I downloaded a 7120p and 1080p trailer and tested and it workd awesome, except for the aspect ration wasent the best. I run tvshows and it works like a charm

Most of the people haven't even gotten their Xooms yet. It IS unfortunate that it doesn't come with 720p decoding build-in, but we know for a fact that Tegra2 can handle even 1080p.
So, like it or not, we'll just have to wait a bit. I'm sure they are working on proper harware-accelerated codecs. Even if Moto isn't, tons of private developers do.
We're early to the party, so grab a beer, sit down and wait for everyone to come =)

I love you..
Ill have to give some fine tuning a chance with my videos. I just coverted a 720p copy of inception using handbrake. I used the apple preset as its listed to work with ipad so i figured it wouldnt be much difference. While the movie and audio do play as they are supposed to im not happy with the frame rate. Its by no means unwatchable. But it is not nearly as fluid as i would like and the irregularity in framerate isnt even consistent. It gets choppier(i use the term loosely) at different intervals almost like im watching a streaming video or playing on a computer whos resources are tapped out. its really annoying because i cant even really gauge the consistency of it becuase its an inconsistent problem.
Im gonna try the settings someone a few post up suggested and see if that works out better. But even if they do its really a shame as most brain dead people can use an ipad. But they expect your average consumer to be able to do all this just to play a frikkin video and still call this thing an ipad competitor?

No one ever said that Tegra 2 can't play 720p. People have said that it can't play 720p high profile, which is pretty much all 720P that one doesn't encode themselves. Basically not all hd video is created equal. Others have said that it can play 720p but is just lacking some codecs.

Apple wants all their customers to just buy stuff of iTunes, so if you do that, it's braindead, but if not, they're in the same boat as us. It only plays 720p baseline (I hear XMBC for it can do 720p high profile, but you have to jailbreak to install it) so it needs to be converted too. Handbreak with presets is what I've been doing for my iPhone 3G, 4, and now Dell Streak.
I've been researching this alot this weekend, and to summarize the issue with 720p/1020p video, the deal is with the various bitrates and profiles of h264 video in particular. NVIDIA Tegra 2 and Motorola only claim to support 720p and 1080p baseline profile. So, for conversion workarounds, there is a Handbrake preset - See Keitht's post. I don't consider this an acceptable solution of course. I keep hearing that Notion Ink Adam's can play 720p high profile after an update. It would be nice to have that player on the Xoom - follow this thread here for info on that. As for now, QQPlayer does the best for 720p high profile - my eyeball guess is that it's playing 10fps now... someone on the forums here did the 1.5ghz overclock and said it's "acceptable" but I don't feel like overclocking my xoom 50% myself
So, I think this will be addressed, eventually. There are WAY to many Tegra 2 devices coming out for someone NOT to invest the time into getting a good player for it - LG's slate, Samsung Galaxy Tab 10.1, Motorola Atrix, etc etc are all going to be Tegra 2 based.
The details in this thread definitely work, and work well. Yes it is going to take a while to convert things and yes that is a pain the ass to re-encode everything but the results ARE worth it.
THANKS
*SIGH* the trials and tribulations of the educated consumer.... why do they mock us so?!?
Great this definitely works. Just finished up a convert of Megamind 720p and it is smooth as silk.

It only plays 720p baseline (I hear XMBC for it can do 720p high profile, but you have to jailbreak to install it) so it needs to be converted too. Handbreak with presets is what I've been doing for my iPhone 3G, 4, and now Dell Streak.
I've been researching this alot this weekend, and to summarize the issue with 720p/1020p video, the deal is with the various bitrates and profiles of h264 video in particular. NVIDIA Tegra 2 and Motorola only claim to support 720p and 1080p baseline profile. So, for conversion workarounds, there is a Handbrake preset - See Keitht's post. I don't consider this an acceptable solution of course. I keep hearing that Notion Ink Adam's can play 720p high profile after an update. It would be nice to have that player on the Xoom - follow this thread here for info on that. As for now, QQPlayer does the best for 720p high profile - my eyeball guess is that it's playing 10fps now... someone on the forums here did the 1.5ghz overclock and said it's "acceptable" but I don't feel like overclocking my xoom 50% myself
So, I think this will be addressed, eventually. There are WAY to many Tegra 2 devices coming out for someone NOT to invest the time into getting a good player for it - LG's slate, Samsung Galaxy Tab 10.1, Motorola Atrix, etc etc are all going to be Tegra 2 based.

Funny because I ordered a Notion Ink Adam before the Xoom came out and should ship next week. Since I got the Xoom, I do not want to open the box so I can sell it brand new unopened. Wish I could at least test the video.
So can anyone tell me does the "High Profile" mean like high compression because when I am doing re-encodes with the previous posted Handbrake settings I am seeing almost double the file output size of the original?

The profile setting indicates the quality of the video stream. There are lots of different profiles within the h.264/avc/mpeg-4 standards but the most common are (snaffled from wikipedia):
Baseline Profile (BP)
Primarily for low-cost applications that require additional data loss robustness, this profile is used in some videoconferencing and mobile applications. This profile includes all features that are supported in the Constrained Baseline Profile, plus three additional features that can be used for loss robustness (or for other purposes such as low-delay multi-point video stream compositing). The importance of this profile has faded somewhat since the definition of the Constrained Baseline Profile in 2009. All Constrained Baseline Profile bitstreams are also considered to be Baseline Profile bitstreams, as these two profiles share the same profile identifier code value.
Constrained Baseline Profile (CBP)
Primarily for low-cost applications, this profile is most typically used in videoconferencing and mobile applications. It corresponds to the subset of features that are in common between the Baseline, Main, and High Profiles described below.
Main Profile (MP)
This profile is used for standard-definition digital TV broadcasts that use the MPEG-4 format as defined in the DVB standard.[20] It is not, however, used for high-definition television broadcasts, as the importance of this profile faded when the High Profile was developed in 2004 for that application.
High Profile (HiP)
The primary profile for broadcast and disc storage applications, particularly for high-definition television applications (for example, this is the profile adopted by the Blu-ray Disc storage format and the DVB HDTV broadcast service).
You'll probably find a lot of movies available via "usual sources" are in high profile. On mobile devices these usually require some form of hardware acceleration to play due to the high bitrate. Not sure if there are many tablets that can play 1080p high profile natively. The Galaxy Tab is certainly one, but those devices with Tegra 2 chipsets do seem to have a hardware limitation with regards to playing high profile (and hence high bitrate) video. It'll be interesting to see how the Samsung 10.1 fares, as that happens to also have the Tegra 2 chipset. Samsung have always been good at hardware accelerating video, so it would be a backwards step for them to release a new device that can't play media that their previous device could.
paul so basically the xoom can only do 720 p baseline?
do apps like Rockplayer and Vplayer help? (without converting)

I'm sure 720p baseline should be fine with any player. 1080p baseline should be fine. Probably main profile too. The problems arise with high profile HD material, which unfortunately is what a lot of stuff out there is encoded with. Then again, I guess most people aren't going to stuff HD movies on their tablets. The 4GB max file size on fat32 gets in the way as much as anything else .
As an aside. I've been using Plex server to transcode and stream movies (including bluray rips) from nas to tablet (running Plex player) with excellent results. But that's probably best left for another topic...
Like the thread title says ive seen way too many posts bashing the playback quality so to those people watch this video on your xooms browser and you will be impressed and appreciate it more

I think most people are talking about videos that they load onto the device sometimes has choppy playback. We know YouTube plays great. I haven't loaded much onto my device yet but you do experience some slowdown or choppyness I some videos. Most play without a hitch for me though

I have several blu ray rips on mine and I haven't experienced any issues so far I converted using handbrake
I think the issue is the software people use to rip.
Granted I don't have my Xoom yet but I've read a lot of threads in preparation and I think the problem is the profile used to rip rather than the software. Apparently high profile 720p isn't working on the Xoom.
Hopefully it's a codec thing and fixable by either Moto adding the codecs or some third party app like CorePlayer.

There is a Xoom profile out there that works perfectly. See middle of this page http://www.xoomfaq.com/video/
1080p is a size not a measure of quality. I had a standard def camera that will shoot a better picture than my handheld HD cam and will shoot better than any phone or tablet camera. I do not know many that can tell the difference between high quality 720 vs 1080. Probably the same folks that can tell the difference between a 160kbps MP3 file vs a 300kbps one
Real HD, that plays off your BluRay player, is 48 Mbit/s. No tablet made today can play that level of quality.
Just because nobody mentioned it..
The problem was/is that users feel that most downloadable HD content files should not have to be re-encoded to play on an $600-$800 device. It is not that we can't use handbrake, or can't figure out how to download the preset which has already been posted on XDA. It is time consuming.
I got over it though, because watching 720P Tv shows on the train with the Xoom is awesome.
I loaded a Kenny vs. Spenny episode onto a store display via my Evo's bluetooth and it played fine. If the videos I converted for my Evo work on my Xoom, then that's fine with me, and it looks like they will. I cant tell the difference between 720 and 1080 on a 10 inch screen unless I stare so hard I get a head ache anyway.

The link provided takes you to a page with XML code...how do you import this to Handbrake? Did you create a notepad file, copy/paste the text, and rename it with a .plist or .xml extension? I couldn't find any info on this in the Handbrake wiki.
As others have stated, its a tegra 2 issue. Tegra 2 is incapable of playing high profile h.264 video @ L4.1 or higher. Its a limitation of the video decode processor. As it stands right now, no tegra2 device has been seen playing ANY high profile video at all smoothly. Tegra 2 can play some main profile h.264 as long as its encoded exactly how the tegra2 likes it, ie no b frames etc.
The reason people like myself take issue with this is that the original ipad can play 720p high profile h.264 and my epic4g can play 720p high profile h.264. Neither of these devices were sold as being particularly capable of playing hd content. The xoom on the other hand was specifically sold as being able to play hd content, and the tegra.2 was advertised at being particlarly good at doing so. Then when both the xoom and tegra 2 are released we come to realize that it was a bs marketing ploy and "technically" it can display videos that are 720p and 1080p, but only if they are formatted in a ridiculously specific encode.

This pretty much sums it up.
While I'm keeping my Xoom and have made peace with transcoding my videos I'd be lying if I said I wasn't expecting more from the video playback when I bought it.

This nails the issue right on the head. Most 720p TV shows available on Usenet or via Bittorrent are encoded using video codec H264 "high" settings. From what I've read, the xoom struggles to play these files, which I would not have expected given its hardware specs. I'm still going to pick up a wifi-only model from Costco on Sunday, but I may jump to the Galaxy Tab if it is able to play "high" H264 files.

I'm pretty sure I read awhile back that for small screens (like 27" and smaller), if you're sitting/standing within a distance (say within 10 feet) it is pretty much impossible to tell if something is 720p vs 1080p. It only becomes more apparent on larger screens. Other people have mentioned it's probably too difficult to tell on a 10.1" screen, but I'm pretty sure it IS impossible to tell by just looking at it on a screen of that size. So 1080p is just overkill to me, only if you're going to output it on a large screen or something.

You have it wrong. You lose the ability to distinguish the resolution the further away from the screen you get. Since a tablet is right in front of you, you can certainly tell the difference. That said, it isn't really relevant because the Xoom only has a 720p screen and that isn't the point. We already have 1080p video encoded for use on other devices/screens and we don't want to have to re-encode them to play on the Xoom.

Yeah, totally forgot to mention that. 1280x800 definitely can't play full 1080p.
And yeah, I didn't factor in the "you sit way closer to a tablet than a TV factor," but I still would find it hard to believe that people could tell the difference of 720p vs 1080p on a 10.1" screen (even if you are 1-2 feet away, assuming the screen does support 1080p). Definitely not old people - my parents at first didn't see the difference between SD and HD. Now they can definitely tell and even laugh about how they couldn't distinguish the two at first.
Yes, they don't have the best eyesight at their age now. This is why I usually drive when we go somewhere.

I have the "problem" that I ripped all my movies and shows to fit my iPod classic screen (and the car stereo) at 640x480. I unless I want to watch a mini video I'll have to convert the movies anyway. I don't see what the big deal is. If you change your hardware you should expect to run into some kind of trouble. And honestly, our 720p HDTV in the kitchen has a brilliant picture and is hardly any different from the 1080p HDTVs that we have in other rooms.
The "big deal" is for warez peeps who can't play their warez HD videos. They know nothing about video encoding, and they don't want to know. But they do like to get on forums to whine about how they can't play their stolen goods. I've explained enough times that I feel like a broken record, but willful ignorance is a hard habit to break. But once more into the breach...
@muyoso
>Tegra 2 is incapable of playing high profile h.264 video @ L4.1 or higher
There's nothing that said a H.264 video has to be encoded at level 4.1. For 720p @30fps, 3.1 is fine. Check the H.264 wiki you're so fond of quoting. L4.1 is a warez standard.
But if you want, I can post a high profile @L4.1 clip, and I'll bet it will play just fine. Will you then shut up and leave?
>original ipad can play 720p high profile h.264 and my epic4g can play 720p high profile h.264
Great, no need for you to buy anything else then.
>Tegra 2 can play some main profile h.264 as long as its encoded exactly how the tegra2 likes it, ie no b frames etc.
BS. The Handbrake script I've posted, and people have used, used straight main profile (which allows B-frames).
>Then when both the xoom and tegra 2 are released we come to realize that it was a bs marketing ploy and "technically" it can display videos that are 720p and 1080p, but only if they are formatted in a ridiculously specific encode.
What's ridiculous is expecting devices to support warez videos, all of which are encoded for the PC platform, and many of which are badly encoded.
The problem with your whining is that it's all predicated on warez, and that's not something you can offer as evidence when it's put-up time and you're asked for proof.
>Its a limitation of the video decode processor.
And you know this because how? The Xoom is the first HC Teg2 device, and it's still in beta status. Every other Teg2 tab available thus far were Froyo, and all of them were also in beta status. Everything points to the driver support.
I asked you this twice before, and I'll ask it a third time: If you think the Teg2 is incapable of playing your warez vids, why are you still here?

driver or not, high profile decoding of h264 is a know limitation of tegra2.
http://www.anandtech.com/show/4181/...-a9s-coming-to-smartphonestablets-this-year/3
One of the stones we've thrown at NVIDIA is the lack of high profile H.264 decode support. Tegra 2 can decode main profile H.264 at up to 20Mbps, but throw any high profile 1080p content at the chip and it can't do it. This is a problem because a lot of video content out there today is high profile, high bitrate 1080p H.264.
