How do you think HD will be playing HD videos? Remember the great deception that the Kaiser was.. and I still I'm not over it..
But If it is like my Diamond, will be superb!
However, the screen is bigger, and will require more from the hardware.
Here is a link for a video and in the last minute (8:40) where he runs CorePlayer and watches House.S05E01 - (will it be HDTV.XviD ??)

If someone could translate that part would be great.

bigger screen does not need better hardware , its just bigger pixels that need better battery capacity

Its not only bigger screen... its also bigger resolution (By 25%)...
If its another type of screen, it could even have better performance at less ennergy consumption
Great video tough i can't undestand that language either.

I don't understand what you mean.
the maximum of vids you can play (or lets say that the screen will show you) is ofcourse its own resolution. So you will not see real HD videos as this screen has not got a real HD resolution. But its own resolution is no problem for the CPU. Playing a movie with a bigger size, will just downscale the video to the resoultion of the HD but as there is more data to process, it may slow the CPU more down, depending of how big the movie is. but you would not want to play a 1080p video on this anyway as it would just use up huge amount of storage space, but doesn't look better. You will get the best and sharpest images if you convert your movies to the exact resolution of the screen.
Oh I understood your point, cause you probably use PocketDivXEncoder..
I was just comparing with HTC Kaiser.. On videos as well as other stuff, it sucked.
This is an important question.
That linked video showing house didn't look very smooth, i was hoping for better playback quality than that. Was it the HD, coreplayer orthe video conversion that made it stutter a little?
Does any one know of any other exmples of the HD video playback? HTC say that its makes it closer to watching the cinema on a mobile, is this statement going to be true?

i cant imagine that the HD as any problem with videos. It often just highly depends on the play. Windows media play is crap in playing videos most of the time. But even my old Compaq Ipaq could play videos very smooth.
Some players are faster then others.
language is czech
I thought it was Czech!!
But can you translate that part?
I think that it isn't very fluid the streaming..
Sometimes we notice some delays.. On my Diamond I can see it too..

to answer the original question, no it will not be able to play HD videos.
HD by definition is at least 720p, that's 720p or 1080p by today's market distribution, may be later on, there will be some weird resolution at 960p or something like that. but right now HD video are only available in 720p or 1080p
1. the video chip is not powerful enough to decode HD content,
2. windows mobile 6 doesn't support HD content
3. Touch HD only has screen resolution of 800x640, again far from HD
4. CPU isn't power enough to decode HD content (even a full desktop/laptop 500 MHz cpu isn't enough to decode, let alone a stripped down mobile cpu.)
im sure that this "HD" will have some serious problems on playing good resolution videos ...
man , qualcomm's 528 Mhz is the CPU of htc diamond, and they let that beast to have this heart on his chest ! its not fair
I might complain that the HD does not have a flash, or little base memory - but not being able to play HD video - come on guys, dream on

Look at 7 min, he shows a youtube movie wvga quality. It doesn't play very smooth either. Let's hope its because of a bad connection or something.
And lets not forget that the units floating around as preview units did carry unfinished ROM and early-stage drivers

it will play videos of its own resolution ofcourse, what are you thinking? i don't understand this topic. it has a 480*800 screen and will ofcourse be able to play videos at that size with no problem. and as i said before, even my 6 years old pocket pc could do so. and it woulkd make no sense if you would try to play a video with a higher resolution. as the screen will still only be able to show you 480*800 pixels. ofcourse, if you are talking about play real HD videos, than ofcourse i can tell you it may have probleems doing so. but it makes no sence even trying to do so.
So, take every video you have got and convert it to 480*800 and thats it.
ps: about the youtube video beeing a little choppy:
ofcourse it is, its a youtube video... and on that, it is beeing streamed!! from the net and for that, it runs very well. that has nothing to do with the cpu. its only streaming.

i am thinking of the OP's original question "can HD play HD videos" of course i understand the resolution of this phone and the video it will play.
so i dont know what you are thinking posting without reading the entire thread.
my post, which you quoted was wishing for playing good video at a decent frame rate. sure you can play videos on your 6 year old ppc, but try play, say a jet li movie on there, all his actions are a blur because the framerate isn't fast enough to capture all his kungfu actions. dido for sports videos. you understand now?
and if you are confused regarding why the OP want to watch and HD video on a non HD display, well i can tell you it is possible to put a video with higher resolution on a device which lower resolution display. it will just be upto that CPU to decode and shrink the video. suuurree, it doens't make sense, but it's do-able.. uptill a certain point (resolution), above which it will be too heavy and too much work for the CPU. and if you want to ask why, well i'm guessing 1. the OP was mislead by the phone's name Touch HD, 2. he may not have the time or software or doesn't want to reprocess the movies to 800x480.
and if you are still confused after reading all that.. well... ummm... LOL

technically i disagree, but from a practical standpoint, sure, i'll go with that. those net videos doesn't require much processing power to decode, very little load on cpu.

Traditionally speaking, all HTC devices have very poor video playback .
Till the latest batch of VGA Devices (Diamond and Touch Pro) which i have no access to and hence cannot comment upon, all previous VGA devices had problem playing back video ENCODED AT THERE NATIVE RESOLUTION. (for reference, have a look at this thread http://forum.xda-developers.com/showthread.php?t=324371&highlight=video)
the best i could manage was a 532x300 xvid with a bitrate of 800-1200.
so it will be a very pleasant surprise if the HD can playback video encoded at 640x480 leave alone 800x480.
On a side note, since HD will be pretty similar to the Diamond / Touch Pro , you could probably ask your friends to run a benchmark with different resolutions and bitrates.
does htc hd has the ability to run 720p videos on it or not and if not is there any application to run 720p videos
nop, the HD can't play HD videos

How ironic. LOL
It doesn't seem logical to play 720p videos on the Touch HD anyway. First of all, the max resolution on device is 800x480 and secondly 720p videos take quite a bit of space.
If you really want clarity, focus on encoding the video at the screens native res or even a bit lower resolution. What's more important is the bitrate and the codec.

but my old nokia device n95 8gb plays 720p videos but not in full screen
can we play mp4 videos on htc hd with high frame rate and without the need of video encoder [with program on device ] like nokia devices
don't you think the nokia software somehow converted it ?
i mean a device with a
240 x 320 res playing media in 1280_720 and then resizing it even more ?
would not make much sense as it would have to process that huge amount
of data from 1280_720 to resize it down

HD videos are also 720*480 (480p) videos. And Blackstone can play videos with resolution 800*480. But just mp4 format. So, if you ask me, HTC Hd can play HD videos 480p in mp4 format.
HTC HD, Xperia and maybe some newest HTC devices are only devices that can play HD videos.
You can also watch HD videos on youtube with inbuilt youtube player.

but when i tried these mp4 files at vga resolution it runs at very low frame rate also it is said in the specifications that it can run up to vga at 30 frames per second what is the problem
remember that you cant use coreplayer to play mp4 files and expect a result
the htc albujm app is the best for mp4
i myself prefer 400x240 divx videos
I have Att Fuze(touch pro)
with Coreplayer where i can use the Pad to click forward on movie Videos
like a que forward while watching movies
Was wondering can we Set it on Volume control to forward Video ?
Cos will get a phone HD2
Please if anyone has Coreplayer on there phone
lol
lol, i nearly pissed myself. First of all 720p is 1280x720, secondly a nokia n97 hasnt got a chance in hell of running this video, as stated before it doesnt have the native screen res or the power to pump that many pixels. There are only one oe two phones that will process this resolution but none of them can show them in native resolution and so they are pointless anyway unless they have a HDMI tv out. ( a couple do).
The touch hd can barely play a DVD rip in 480p without losing frames for god sake.
If you want clear smooth video you have to re-encode at the native res of the device and use a code the phone can hardware accelerate, the touch HD can only accelerate MP4 codec and so you are limited to that.
Now the touch HD2... well I was going to get all exited about that until i found it had no TV or mini hdmi out, what a waste of [email protected] time that it. HTC dropped the ball again in my humble opinion.
Tegra is where it is at, bring on the phones, build it and I will come

hello my friend the first ans is it depands on which format u've to play. coz avi format not suported by wmp. After all the best option is to convert videos in littlebit low resolution so it also can't flickring when you play it & feel better experience and laisure to watching videos

480p is hd, but the hd can not play videos at anywhere near enough bitrate to be classed as hd lol also even if you play a video at the same resolution as 480p its not 480p hd unless the image is scanned progressively, rather than in alternate fields.
I noticed on an ipod touch 4, that the quality was HD.
I wonder why the the quality on the Android devices play in HQ.
Side by side, makes me cry to see what I am lacking.
Just odd Google's major product plays better on a non-Google device.

I haven't used YoutTube App much BUT is there a point of playing it at higher quality?
480p = 640 x 480
480p = 704 x 480
our screens = 800 x 480
The benefit we get from 720p -> 480p is fairly minimum as you can see :/
Kinda making this up, but it might be because of the higher resolution display that the iphone and itouch have.

que? are those resolutions the old crappy TV lines that werent really even 480i?
480p= 720x480
720p ( i assume you meant) = 1280x720
So if our phones are 800x480, 480p would be a better image than a scaled 720p, I seriously doubt our phones have the scalers of most modern TVs or Monitors. Native resolution is pretty much always better. (the widescreen images being letterboxed 480p like out of a dvd player).
Yeah they have amazing, almost unnecessary resolution for a 3.5" screen. Great for text readability, but so is SAMOLED
So anyways, if a 960x640 (apple) device is actually defaulting to scaling 720p down, theyre actually shooting themselves in the foot... unless their scaler is a faroudja... but with iOS its all about status, so having that little indicator on the screen say HD, even though the device falls a bit short of actually delivering, and degrading the image by scaling when it is not necessary on such a small device (any phone), it just makes us look better . Wow, im used to having these discussions relating to CRT projectors, not phones So yeah, stick to native resolution or smaller.
That said, if our TV out option worked, then 720p or whatever the best output is would be a good default, if that option were plugged in.

I am not talking about the resolution of the screen. I realize the iphone/ipod have higher res than our phones, and that relates to the sharpness. But I am talking about the actual content quality is actually much higher definition, as it takes longer to buffer because of this aswell. I know the Android app is better overall vs IOS version.
I watch alot of HD [HQ on our phones] of car videos and such, and yes it bothers me that it is not the best it can.

Duh, been too long since I dealt with SD... you are correct.
But as far as 'looks good', its subjective, and looking at my friends touch, I really dont think video is even close... text is awesome... but theres too many factors, such as were you using youtube apps, or the actual site? Really though, I guess it boils down that you really prefer resolution over color, clarity, etc of the samoleds.... But everyone has their preference, I still prefer my Barco 808s projector running 720p CRT at 120" over most 1080p TVs... But to be fair most TVs are crap...

Yeah I noticed that too,compared even to my old iphone 3gs I just watch youtube videos using Dolphin Hd browser with AdobeAir flash installed,quality is definetly better than on YouTube app.
What I'm more concerned with now is actually watching a youtube video and not watching 3 seconds of it, it skipping, and then having to start over because it fails to load completely
The old youtube app was horrible and would always do that but the new one has been awesome so far.
Yea that's true, the new is way better for reliability lol

download a program called tubemate from the market. its free.
when you use this app, you browse it just like you would youtube , but when you watch a video you have 2 options. watch or download. when you watch it steams in poor quality, however if you download you can play it back in HD. its pretty cool. you can even download 720p ( on 4g its pretty quick)
ORiginal desire got the ability to record 720p videos . Even iPhone 3gs which was able to record vga video was able to record in 720p after a work around.will it be possible on desire HD to record full hd 1080p videos with any kind of work around
Sent from my Desire HD using XDA App
I'm not a techie but 720p usually means 1280 by 720 pixels where 1080p means 1920 by 1080 pixels. It's quite a jump between those values and even with a workaround that quality could be poop
the sensor won't be better with any change
It will just use more space from the sdcard
The sensor is capable of recording 1080p, but the processor is not capable of encoding in full hd. So no - it's not possible.

Nope, if the processor was capable of encoding 1080p, the video won't be just an upsampled version of the 720p video. It would be a true 1080. It's not the sensor alone that's responsible for the video quality - there are the lenses and the hardware encoding. And these (especialy the lenses) have the negative impact on our video recording IMO.
If not full HD then least some workaround to improve the current state. Audio really suck and video I dark most of the times. Really disappointed with the video quality on desire HD

to be able to record in 1080p would be great enhance but I bet changing from stock sd card is required it seems. class to won't do good with 1080p recording. correct me if I'm wrong
I wouldn't have thought a Class 2 card would anywhere near fast enough for full HD.

Galaxy S2 has a dual core CPU.
We would need that, if we ever manage to capture in 1080p it would just be a slideshow because the CPU cant keep up.

lol, looking at youtube "not" HD movies to see if the HD movie on the phone looks ok
This is a very bad example, to trully show the screen quality the videos should be converted at the max resolution of the screen.
Puting bigger resolution videos than the max native screen res will result in pixelation, because the phone then has to convert the video in realtime which is a much worse conversion than first doing it with a decent software and then displaying it on the screen without need for picture rescaling.

a voice of reason. I got tired saying this. a good quality 480p (standard resolution) video will play the best on SGS2 , to fully and natively fill the 480x800 screen.

not to be a **** but isn't 480i standard resolution and 480p the first step towards hd? again could be completely daft but that's my understanding.
like i = interleaved, p = progressive
thus
p > i ?

I would call 480i an interface, not a resolution.
Most standard DVDs (and all modern standard DVDs) have video on them with 480 lines of resolution (480p). Some earlier DVD players (like from 10-15 years ago) could only send that 480 lines of data to TV interleaved (240 lines one frame, 240 next frame). All modern DVDs connected with component or HDMI send the unaltered 480p to the TV.
In phones, you use progressive by design (every frame is shown as full 480 lines of picture)
When you take a 1080p bluray and send that 1080p video to phone straight away, your phone will downconvert 1080p to 480p to show on a 480x800 screen. That downconversion process will produce WORSE resulting picture than a studio-cut original 480p standard DVD.

alright that's just how I understood it... that and an xbox 360 running on my old 32 inch tube tv won't give me a resolution higher then 480i lol
Edit: another question though... does 480 lines necessarily mean it's 480p? I though it also had something to do with the post processing done on the monitor as well?

If your TV is capable of physically addressing 480 lines on the screen, it DOES have resolution of 480. However if the circuitry can only produce those 480 lines in two passes by 240 lines, each pass showing every other line, then you are seeing 480i picture.
CRT TVs where a ray is used to quickly draw every single line, and that ray is not quick enough to draw 480 lines for every single frame, it would use 480i to show half frame each time.
480 lines for each frame are stored on your DVD. If you connect DVD player to TV with a composite cable you can only pass 480i signal. Same if your TV can only accept composite, or produce interlaced picture.for any reasons (see CRT example above).
With phones, you are not passing signal over any cables, and LCD/oled screens have enough power in the hardware to show all 480 lines at each frame. So you always use P in phones for videos.

True but i would like to add that 480i not a simple limitation of CRT, there are hundreds of CRT out there who display resolution of 2048x1536.
The main problem was the bandwidth of the cables themselves and not by the CRT technology.
The 480i is indeed long gone, it was used when analog signals were simply not prepared to output such a high definition, therefor to overcome that situation, tvs were made with an interlaced technology, basically displaying the same frame twice on different vlines of the screen, giving you the illusion that the image was beying displayed at a bigger resolution, even though it wasnt.
So he is correct when he says 480p as a more standard resolution than 480i, especially since we live in 2011 now and Interlaced imo is not really a true resolution.
Think of 1280*720p vs 1920*1080i, alot of ppl would prefer 1280*720p over the interlaced especially since lcds cant handle interlaced outputs as good as crts can.

I'd just like to point out that I'm not completely retarded.... hell I'm a Computer Systems Engineering Student (what would happen if Electronics Engineering and Software Engineering had a kid) I know how CRT works lol I was just asking out of clarification no need to make a guy feel dumb
