Questions on video formats - Acer Iconia A500

I used Handbrake to convert a 1080p video to baseline.. I have a couple q's:
If ever ripping/downloading a video, should I just get it in 720p or is there a big quality difference between 720p and 1080p baseline?
Is there a big quality loss between regular 1080p and baseline? Or is it just the way it's encoded?
Is there a way to get handbrake to save the configuration?
Thanks! This is my first tablet, I love it!

You should definitely get high-profile 720p instead of 1080p baseline one: especially in high-motion scenes you'll quickly notice blocking artifacts from the compression. Also 720p high-profile takes a lot less storage space.
Also do notice that the tablet screen is only 720p.
Is there a big quality loss between regular 1080p and baseline? Or is it just the way it's encoded?

Yes, there is a noticeable quality-loss. You could in theory encode a baseline-one so that the quality is the same as on normal- or baseline-profile one, but you'd end up with a 15 gigabyte file.
Is there a way to get handbrake to save the configuration?

Save it as a profile or grab one of my profiles from the sticky thread.

Wow, thank you so much, that answered all of my questions. I'll go for 720p from now on.
I just noticed an error in my post "If I ever ripping/downloading a video".. I meant "If I'm ever ripping/downloading a video".. lol.

he asked for "download"
if you are to encode movie for x10, I think there is no point encoding it more than the screen's res, cuz it will look the same anyway
i didn't say download. look again. but even with a redeem code with dvds and blu rays, the file formats are mpegs
they don't have to be high res. just decent quality so i can enjoy movies on the x10

I guess hd mp4 from youtube would work, not sure though, I'll try and report back
For encoding, try Handbrake. It works really well using the iPhone preset (just make sure to adjust the video width to 854 pixels).
A Blu-ray rip of an episode of Dexter I have looks amazing.
what is handbrake?
Google it!
http://handbrake.fr/ it's a free Windows app that allows you to re-encode video files.
Anyone try and encode an HD movie on handbrake ?
I convert a 8gb 720P movie, set the bit rate at 1500...The vid took about 8 hours convert, and ended up being 3gb when done...set at 854x480...I also tried designating the output file size to 1.5gb, still took 8 hours...Been using Handbrake for a while now, quite familiar with the "advanced" settings, but taking so damn long to convert 720p movies. Love it none the less...

My conversions of BD rips of 1hr TV shows seem to take a bit over 60 minutes each. That's using the iPhone preset with an 854 width setting.

i concur, the X10 is capable of 720p playback. I've converted my own AVCHD 720p files and they play perfectly fine on the X10....which is AWESOME.

Technically, it's not playing 720p. The 720 refers to horizontal lines of resolution, not the vertical lines. 1280x720 is the resolution of 720p.
The X10 is capable of playing what YouTube and other sites call "480p", which is pretty much what DVDs are encoded at.
this is great guys. thanks alot, im going to try to download handbrake and convert my mpeg movie files
i agree, x10 can play some really HQ files though i find little use of it, a "normal" 350mb episode or 700mb movie will do fine when coverted to .mp4
it's a pitty x10 doesn't have TV-out capability...i had X2 and it worked pretty nicely
is there any way that picture from the x10 could be sent over wireless or am i just talking nonsence maybe an app that would show on your PC the screen which is on X10

This is incorrect. Yes, the X10 is capable of playing 480p, but you make it sound like it can't play anything above that resolution because the screen itself is 480p.
If you play a 720p video on the X10, it will be downscaled to 480p, but the X10 is still decoding the full 720p video which takes quite some horsepower. I used Handbrake to convert a 1080p Youtube trailer to 720p, which the X10 plays, but not without some stutter. Maybe my bitrate setting were a little high and the X10 could play it smoothly on lower encoding settings, but the fact that it plays a perfectly fine quality 720p even with some dropped frames is still pretty impressive.
And no, it's not really usefull to playback any video with a greater resolution that the X10's native screen resolution, but it's fun to play around with IMO. I do wonder if the media player has GPU acceleration. If not, that these results are all the more impressive.

YouTube HD

Hi guys, I see a lot of GB roms mentioning YouTubeHD, yet I can't seem to get it to work, I get the HQ button that's always been there, but not 720p, any ideas?
Well, mobile HQ isn't 720p either. I don't see why you would want 720p in the first place, your phone doesn't have that many lines?

I'm quite aware of both of those things, but it has been mentioned that YouTube works in hd for the HD2 running Gingerbread. And I know from my own testing that a 720p encoded movie looks a lot nicer on the HD2 than a 800x480 encoded movie.
Uhm I haven't heard of any of that, and Google doesn't hint anything in that direction either, I think you're confusing some stuff. A lot of roms support 720p playback, but not in Youtube.
720p in se doesn't look beter than a 480p video by the way, on the contrary. You don't see the lines your screen can't show, and actually this may even result in a slightly worse video because of it.
A well encoded 480p video is at least as good as a 720p video, problem is that a lot 480p conversions suck. But that's not because it's 480p, it's because of the conversion.
That's why I don't think we'll ever have 720p mobile video. It's just wasted bandwidth over a nicely encoded 480p.
Oh, and I think Youtube HD just refers to the revamped app. Not 100% sure though so don't quote me on that.

Totally 100% agree. There would be more chance of performance issues with a downscaled 720 video on a 480 screen. It DOES NOT look better than a properly encoded 480 video. It is not physically possible for it to look better as your screen cannot show anything more than 480 pixels in each of the 800 columns. End of.

best video format on evo 4g?

some people say it's mp4 with decoded with H.264 and some people say it's wmv. i've tried them both on my evo 4g but still can't figure this out.
have any ideas?
I personally don't see any difference in picture quality other than file size. However, if you plan on using your HDMI cable, I would be more concerned with the resolution size, than the format. That's my 2 cents.
Sent from my PC36100
I read on Android Central a long time ago that MP4 was the extension the EVO liked best. If you need help converting videos, I recommend using Handbrake. After you've downloaded your video file, load it into Handbrake and use these settings to make it EVO-friendly:
In the picture tab, set Anamorphic on None, and adjust the resolution. The EVO can only accept as high as 1280x720. Leave Keep Aspect Ratio checked. This will ensure the video doesn't get squished or is too tall.
Skip Video Filters.
In the Video tab, use MPEG-4(FFmpeg) as your codec. Under Quality, I find it easier to aim for a specific file size than bitrate. The EVO supports HD files up to 2GB, as I've noticed any higher results in lag.
In the Audio tab, choose whatever settings you please for output. You really don't need to change anything here.
And that's it. Any questions feel free to PM me.
Both h.264 and 3gp will give you the same result with this phone. Generally, h264 is a GREAT codec, it's what is used in blu-ray's as it compresses very well and leaves a lot of quality. However, on the evo of course, using h264 limits you to 800x480. Now, switching to 1280x720 would give you a better picture you would think. However, of course you have to use the 3gp codec, which is probably over 10 years old, and is horrible at compressing video. It really wasnt even meant to be used on video, just audio.

I agree with you. What I do is convert using Handbrake and select iphone4 preset. Works great on my evo.
x2 on mp4 for a smooth running video, I use iPod or iPhone settings when selecting a conversion.

Movie resolution and bitrate?

At what resolution and bitrate do you encode your movies for Note or similar mobile devices?
Okay, I encoded Kung Fu Panda into x264/AAC with Handbrake. I chose 800kbps as average bitrate and 128 as average audio bitrate, encoded with 2 pass + turbo first pass at a resolution of 1280 x 540, it's about 1:32 hours and it came out to be 615MB. I'm very space conscious as I don't have a lot of space considering the amount of crap I want to put into the Note, but this seems quite good.
EDIT : Hmm...800kbps is indeed a bit too low for this resolution, I'm going to try 1000kbps.
encode?

I would just use m720p 1-2GB for the space concious ones.
For me 3-4 movies of 2-2.5GB each are spot on. Space wise.
And another 16-32GB microSD is a must this days.

Pretty subjective thing though wouldn't you say? Hard for anyone else to advise you on what the right rate is for you. Videos I have at ~7000kbps total bitrate look OK to me, so maybe start there and do a few brief encodes of the same thing at 5 and 3mbps and see how they look to you.
Others might be interested in this, since they will come here to see information on video playback:

Tegra 2 missing NEON video decoding instructions - any solution to be expected?

the Iconia tablet (stock rom 3.2) has a most troubling issue: no (or no smooth) video playback of HD video files, mostly H.264 encoded mkv and mp4 files. Acer and Nvidia claim the device can run 720p and even 1080p in h264 base profile but the bitter reality is that even 90% of 720p video files don't play smoothy due to lack of proper hardware acceleration. this is really a huge disappointment as even most of today's discount phones can play 720p video and i got me a dual core device with a HD screen and a GPU from a dedicated graphics expert company but have to stick to SD video.
i found a statement in the Nvidia developer forum saying that Nvidia is working on this problem with some software partners which indicates that there might be a software solution to this sometime soon:
http://forums.developer.nvidia.com/...6/is-tegra-2-support-neon-intsruction-set-/p1
my question: is a software solution realistic or maybe just a waste of time? personally i doubt it, especially since the successor, Tegra 3, again includes NEON.
but maybe a custom rom like Thor could add enough horsepower to the device to enable at least smooth software decoding? anyone using this rom already noticed a performance gain?
i am looking forward to your comments.

you think i would investigate in hardware related stuff and post here if there was a player that could handle all HD video? MX player clearly does not, nor does any other player (dice, mobo, rock, just to name a few of the better ones) handle high profile H.264 video on Tegra 2 devices. so 90% of the stuff available online is not working, means they wont play at all or have massive framerate and sound issues. go and check out the latest movie trailers available in 1080p mp4 or download an x.264 encoded mkv file of your favourite tv show and you can see for yourself.
if you insist on your statement, then please put up a video source so i can verify. i would really love to learn that you are right and i have just a broken device ;-)

there might be cases where a hard- or software scaler messes up while downscaling a video and picture quality degrades, but generally the higher the resolution the better the picture quality, regardless of display resolution.

Atleast I can play baseline and normal profile H.264 content at 1080p just fine. It's only high-profile that reverts to software and doesn't play well.

The display itself is 720p, so trying to play 1080p content on a 720p display is kind of pointless. You won't see the extra resolution anyways. Though if you're playing through HDMI to a 1080p display then it makes sense.

Not entirely correct. Higher resolution doesn't equal better compression quality, so you can easily have 1080p video that looks like ass crap, and you can have SD video that looks better.
That said there are lots of reasons to choose 720p over 1080p on A500: 720p high-profile video generally looks much better than 1080p baseline-profile, high-profile fares a lot better in high-motion scenes, and high-profile takes less storage space than baseline-profile. And well, since you can't see the extra resolution anyways you're just wasting extra storage space on stuff you can't even see.

A software solution will only boost applications that are specifically designed to utilize it, and the hardware simply isn't fast enough to decode 1080p high-profile in software at full speed, so no, no matter what NVIDIA is claiming they cannot do magic tricks here.

Thor or some other custom ROM can only increase clock speed, there is nothing else to be done about it. And you can increase clock speed even on the stock ROM anyways.
But as I mentioned I have absolutely no problem running 1080p baseline- or normal-profile content, or 720p content, because I am not using the stock player. Use one of the players from Android Market, they're a lot faster and smarter than the stock player.
Also an important note to you: the stock player reverts to SOFTWARE if audio is AC3 encoded. That is probably the issue you're seeing. The players from Android Market do AC3 in software, but send the video to the hardware, so that's why they don't lag with AC3 audio.

I was on topic, if you can't understand that attempting to play 1080p Res videos on a 1280x800 display has no benefits whatsoever, then maybe you need one of These.
I honestly don't understand what is so friggin' tough about understanding the concept, and you clearly stated 1080p in your first post.
He's trying to playback through the HDMI port, muppet.
Here ya go, educate yourself.
" If the incoming source has more pixels than the display's native resolution, you will lose some visible detail and sharpness, though often what you're left with still looks great.

guys, and ladies, please, this thread is not about pro and contra of full hd content on smaller displays.
the question is:
is it likely that (at some point soon) there will be a workaround to overcome the issue of the missing NEON video instruction set on Tegra 2?
again, my goal is not to play 1080p content on my Iconia, just some 720p stuff, mostly TV shows encoded in H264 high profile mkv files. and no, they wont run using MX player or any other player currently available. and i guess that's also due to the missing NEON. please see the link provided in my first post.

I already answered your questions.

A software solution will only boost applications that are specifically designed to utilize it, and the hardware simply isn't fast enough to decode 1080p high-profile in software at full speed, so no, no matter what NVIDIA is claiming they cannot do magic tricks here.
Thor or some other custom ROM can only increase clock speed, there is nothing else to be done about it. And you can increase clock speed even on the stock ROM anyways.
But as I mentioned I have absolutely no problem running 1080p baseline- or normal-profile content, or 720p content, because I am not using the stock player. Use one of the players from Android Market, they're a lot faster and smarter than the stock player.
Also an important note to you: the stock player reverts to SOFTWARE if audio is AC3 encoded. That is probably the issue you're seeing. The players from Android Market do AC3 in software, but send the video to the hardware, so that's why they don't lag with AC3 audio.

thanks. well, in respect to 1080p content i don't have much hope either. but, and again, 720p content encoded in h264 high profile does NOT work for me. i have massive framerate issues and sound also drops off completely after a few seconds. i tested with google, rockplayer and mx player (all of the latest builds).
here's another example file for you and everyone else to check and report back:
The.Walking.Dead.S02E06.PROPER.720p.HDTV.x264-ORENJI.mkv

You sir are an ignorant boor who is incapable of reading. You couldn't read the posts properly and you can't even read your quote properly.
A 1080p file has more visual information. For example, it's possible to see a small mole on somebodies face in 1080p that in 720p or lower has been smoothed out and is now invisible. Playing that 1080p file on a lower resolution device gives the possibility that the mole will be visible depending on how the hardware scaling is done and since most hardware scaling isn't going for compressed file size and won't be applying gaussian blurs etc... you WILL see that mole.
The new Nook Tablet and Kindle Fire have the same screen resolution, one streams videos at SD and the other at HD. Now even though the tablet isn't capable of HD the one that streams HD is noticably sharper and has more detail. Go look up the pictures if you want. Take your own advice and educate yourself before you berate people for their ignorance when it is you who are ignorant with poor reading comprehension.

Mate, it doesn't work like that. It doesn't matter if the picture is scaled down before compression or after decompression, it's still scaled down. And no sane compression technology uses gaussian blur.

The difference is due to the fact that the HD video is compressed with better quality settings than the SD video. Besides, Kindle Fire IS 1024x600 pixels in size which means it is indeed almost 720p HD resolution meaning that HD content only needs to be scaled down by 120 lines whereas SD content has to be scaled UP instead: well, OF COURSE it will look like crap.
In other words you're comparing apples and oranges and you don't know what you're talking about either.

I just tried that file with Dice Player. It stutters for about 5 seconds, then settles down and works like a dream. In other words, working just fine on my tablet.
I had problems playing 720p mkv files as well, no matter which player I used. The stock 3.2 rom appears to be missing the framework for hardware decoding of these files. No such problems since installing various Thor roms though. They all play fine now. 1080p is probably too much though. I use mx player by the way.
