anyone confirm this
thanks in advance

There's a two-part video review that tried several bitrates and came up with an ideal for multiple formats based on CorePlayer's benchmarks. Check the video review thread.
As for 720, that's a 1280x720 resolution, so if you're converting specifically for the TP2, it's a waste and will yield lower quality video than a lower resolution because the device is having to scale it down. Shoot for 800x480 if you want the video to be ideal for the device.
Best converter is going to be a matter of personal taste. Many of the free compression programs out there are just frontends for programs like ffmpeg and mencoder, so the quality ends up being the same. It's just a question of what interface you prefer.

Hi guys,
have you looked here...

ive used the convertor terryd1980 linked to. and its great, slow on my pc (though that'll be my pc's fault) but after a small problem in using large 4gb+ files it seems fine now.
i did a bit of a test with a tv episode. a 1gb 720p file converted with the above and played through album (with a bitrate of 750), compared to coreplayer playing an unconverted 200mb dvd rip. although the dvd rips still looked excellent and played perfectly the originally hd file looked a touch better. i didnt notice any playback issues and there didnt appear to be any skipped frames. i dont know if there's anyway to display how many frames were dropped using album, but coreplayer shows 0 dropped frames after its finished playing.
I dont think it is your computer Jamie, mine runs fairly slowly too and I've spent a lot of cash making my PC pretty beefy.
As it seems to do a great job converting I'm not too fussed but I will leave it going in the background or before I leave for work so that it doesnt bother me.

greate .. thx
The video quality is not very good. I was under the impression (from reviews) before I bought my Desire that it would record at close to 30 frames per second (fps), but I'm only getting frame rates of 13 - 16fps which is brutal. My nokia used to record at 28 - 30fps.
Was I wrong to think the Desire would do 30fps? I know the HD recording was not coming etc, but I thought 30fps was standard.
brutal.
It is standard alright. My Nokia N95 8GB from 3 years ago took much smoother videos @30FPS. Hell, even an LG Viewty from 3 years ago can record at 120FPS and that's not even a smartphone.
We're getting 720P recording so i'm assuming they will fix the FPS issue aswell with the video recording. If they don't then I can only imagine how slow 720P recording will be.
I've noticed the same thing and am quite annoyed about it. I've realised through testing that the brighter it is, the higher the fps is. I got it up to 20fps today outside but indoors its more like 10fps even when using lower resolutions. Maybe the reviewers should have tested this rather than just quoting the specs.

The Snapdragon CPU supports 720P encoding and decoding hat and apparently HTC confirmed that DivX and 720P recording will be coming to the Desire in an update.
Let's hope they keep their word.
Yeah I agree, the reviewers should have done their homework instead of 'guessing' the stats. I guess they thought it impossible that the Desire could have anything less than 30fps. The Nexus one is listed as 20fps minimum rate. Is it really faster than Desire?
GSM arena who are normally very reliable had 30fps as the Desire recording rate until recently. now its 15fps on their Desire stats page.
I would not even be bothered if HTC don't bring in HD video recording, once they at least bring 30fps at 800x480. I mean its a 1ghz phone with plenty of RAM, this should be a piece of pie for it to handle. My nokia had a 300mhz chip and 128mb of RAM and did it no problem. (640x480 @ 30fps)
Well personall I think the video recording is pretty good. Its definately better than my old Xperia X1.
10 - 15fps is 'passable' but not very good in real world terms. Certainly not on a cutting edge 1ghz phone thats capable (hardware wise) of recording 720p at 30fps. I used to get 30fps video from my old N82 and its more fluid than on the Desire. As I say, its passable on Desire, but I think 30fps is pretty much the accepted minimum for the past while. Lets hope it comes in an update.

Well, hope dies last. HTC and their word... Have a look at Hero topic, and search for the so called 2.1 update for Hero. Shame on HTC!
Sorry for the offtopc.
Hero update is near, as a matter of fact (tweet this week from HTC Benelux director).
I think this is a software limitation slowing the exposure on low light to brighten the image. it'd be nice to be able to adjust this feature though.

there are alot of Desire made videos on youtube already. just do a search. They look 'ok', some of them, but the original files are still only about 16 - 18 fps at best! 30fps nakes the video seem more fluid. You'd really need to compare side by side to see the difference I mean. (I attached 30fps nokia clip at bottom. WOW for the difference. very obvious)
http://www.youtube.com/watch?v=Dnxcfjq3QvE (desire at 15fps)
and another
http://www.youtube.com/watch?v=rnRpOSP0U-o (desire at 15fps)
and now compare to the lower res 640x480 Nokia but filmed at almost double frame rate of 30fps. Very fluid and sharp.
http://www.youtube.com/watch?v=ojt5LS4LFZc (Nokia X6 at 30fps)
I think alot of people will be impressed and happy enough with this level of video recording. I was just irked as I expected 30fps and thought that was pretty much the minimum on new phones now.
thx . i think the vid qlty is gud on desire .... hmmmm .... better than x1 anywayz by the looks of it
My N95 8GB outperforms the Desire in video recording. What's the point in a high res video camera if it records at 15fps?
I get 12fps indoors... haven't seen higher in over 50 recordings. Colour reproduction is also off. N95 sure does beat the pants off it in this area.

How do you tell what frames per second you're getting? Can't seem to find anything in the phone that will tell me.
Well now there is root acces. So this means we can put custom roms on our decvice and/or we can adjust the build.prop so we can also adjust the camera settings...
Personally I think there is no need to worry. Just have patience
Cheers Bart. Patience it is.
Meson1 I use a codec analyser like 'gspot' to look at the details and properties of the video files. If you use Windows 7 you can also just click on the file in explorer and it displays the frame rate and associated details at the bottom of screen.
Its easier to just long press the video and select details to see the frame rate and other info.

Okay, so I know absolutely nothing about ROMs, so this is mostly a question of if this is possible:
Currently, the EVO's 720p video recording is lackluster. I find that the biggest reason for this is the bitrate of the video used. I imagine that the bitrate used on the video was to accommodate the included microSD card's Class 2 write speed.
Is it possible to increase the bitrate used for encoding of this video, to something ~5mbps, to which a Class 6 microSD could handle just fine? Ideally this could even be implemented as an option in the camera app, so that those who don't have/can't afford a class 6 microSD could still use the ROM.
If that is possible, what are the chances of having the video also record using a different audio codec? The current codec used is pretty much impossible to play back in anything except Quicktime (VLC's latest release candidate just added support, but it still sounds awful, like a pack of hyenas on top of the track). I'm really not particular on what audio codec is actually used; be it mp3, ogg, etc, as long as it's more easily played.
The best case scenario, the DREAM EVO ROM for camera capability for me, would be:
1. At least double the bitrate (4-5mbps) for the 720p video with an option to use old settings.
2. A better audio codec using higher quality settings (minimum 64kbps mp3/ogg/similar) that is playable in many more programs.
3. A more compatible container format like mp4/m4v.
Am I dreaming or would this be possible in a custom ROM?
Don't forget it will also be limited to how fast the hardware can encode the video. Someone with the right skills will have to push the hardware encoder to see how high they can push the bitrate without exceeding real time.

Yes, there might be hardware limitations, that's sort of what I'm asking; if this is something that can be "fixed" in a ROM or if we're stuck.
I think as long as it can handle the bandwidth though, I don't see why the chip would be incapable of higher bitrates. I'm not an expert on the matter, but I thought that the less compression/higher bitrate something is, the less power was required to make it happen.
well im pretty sure this is possible, if a dev puts the time and effort into such a large project. i only say this cause the nexus one recently got 720p video recording, something it didnt have from the start. and i think its known that htc made the video recording compressed, so i think theoretically if we lift this compression and use a different form of compression, we can get higher bitrates from the video.
Yeah, I'm hoping a developer can investigate this thoroughly. Even if it takes a while, it'd be nice to know someone is at least looking into it.
And to make it worth their while, I'd be more than willing to pitch some donation funds towards such a project when it becomes successful. I doubt I'd be the only one as well.
I was wondering this also. I'm not up on the technical aspects of this, but I was also wondering if the 720p could be improved through software fix/ROM development? I agree also that I'm sure a lot would be willing to donate for such a fix.
I'm sure eventually we will get a better cam, i mean look at the how the nexus got 720p video
You can easily get 720p at 60FPS... The snapdragon can support it.
i would most certainly donate for this improvment
yup i would donate as well
we just dont have as lively a development community as the nexus yet, but we will in time - we;re gaining momentum fast

Go look at the Nexus One forum... They've got up to 1080p capture.
Realistically though, it seems silly to rely on our phones to capture HD video. I have a G9 that does that task quite handily.
All I could find was 720p capture at 20fps and a max bitrate of 12Mb, which is plenty.
This is interesting, I'd like to see this happen as well.
I'll do what I can in terms of research.
Better low-light pictures too, if at all possible

I'll start:
http://www.youtube.com/watch?v=NxxPdPd8ea4
Description:
Me being very concentrated while playing the Drums... new song Bad Lighting hard sound situation (way too loud for this little Phone ) so worst case
Problems:
I see constant drops in FPS, or more likely a stuttering ever few seconds video playback just kida stops, audio is fine though! I did not have this Problems with other Roms so I think its not my SD card acting up?
FPS: 5-11 not very constant at all, although lighting was very constant (although very bad)
ROM used: LeeDroid 7.1b
Before official update:
http://www.youtube.com/watch?v=ugjI5ygsXzQ
Average/good lighting
20fps
Can't remember the rom, I think MCR v5, it was before the official update.
Not a lot of stuttering that I can notice, but the lens cover was a bit smudged and so the video came out a bit opaque.
After the update:
http://www.youtube.com/watch?v=S6KuPCn6_2M [quality should improve in a bit]
Probably a tad better lighting conditions
23fps
ieftm semi-stock rom
This is the best sample of three, one was ok, but the last one was stuttering quite a bit, as I think some background program was accessing the sd card heavily. Also lens here was a bit dirty
by the way, youtube quality doesn't render properly, linking videos should be better.

No, I think it was me that turned contrast a bit too high and the fact that without optical zoom or camera lens optics you can get lose details in the distance on such high resolution
I gave up 720p, it is not good. Jumpy, low fps and especially ****ty voice quality.
I use 480p, but it is also not good, not too jumpy ... still ****ty voice quality.
I have 2.2 rom from here and 720p keeps freezing every few seconds.
720p is ok for me. Is it possible that its to do with the internal memory available? I have 60mb or more free, I know some people are down to low numbers. my card is a class2 too. I think the clips look better played on the PC in VLC lpayer than when I upload them to youtube. I think youtube might be introducing some of the negative aspects seen... maybe?

720p is crap, its just upscale from lover res., dont use it.
more info:
The data rate of 720p is over 4 times greater than 800x480. 6000kb/sec versus 1200kb/sec. It's not purely upscaled at all. I made two sample videos of a page of text and compared.
There was ALOT more detail in the 720p video. Even when I zoomed up the 800x480 one. I agree it's not as good as "true 720 HD" but its certainly not 100% upscaled.

1200:6000 it's 5 times more. Yes it's not true 720 hd, but I can perfectly live with that quality if we get a couple of fps more
I've taken two short videos of a label, took screenshots from video player, cropped them, resized the 480 to fit the same size as the 720 one. It's very blurry compared to the normal 720p. See the hour in the fake pda, you can't read it in the upscaled one.
Video upscalers tend to do a better job than a simple photo resize and they do introduce more data leading to a larger file size. The disire may truly just upscale the video after all. In any case, its a shame that video capture on this device is as poor as it is. I dislike Apple and their iphone, but i'll give them this; all aspects of the software work very well from go and if not, a fix/upgrade is provided in a reasonably short time.

Given the current state of their last shiny toy, I think it's a bit funny to say so.
Anyway, I've done some more tests and I can take the screen captured from a 480 video and upscale it with any tool with best quality or other algorythms and you always end up with a lot less detail than 720p, especially when there is a lot of light (unlike that test above). I don't think the desire has the processing power to do a better upscale than what I'm trying and while there might be a bit of upscaling given you have a tiny lens, it's not all there.
Also any tiny lens without zoom is pointless when taking videos from the distance anyway.
I can only get 15-16 fps... anyone can do higher?
I can easily get 25 average, outside in. good lighting, with a class 6 sd

I talked to some iPhone engineers about how the iPhone can archive 30Fps ... its because all the decoding of pictures delivered by the camera is handled by the GPU... for Android its all done on the CPU! so we need to find a way to decode the video stream using the Desires GPU, but I think the iP4's GPU is far better than the Desires... i am a hardware engineer... i am in no way able to code anything like that! What Makes me curios is file size comparison between an iP4 and the Desire.
Also: Desire running a non sense rom (AOSP) just like the Nexus gives much better 720 Quality!!! so I guess its in the software

SInce I am NEITHER a hardware nor software engineer, I am useless here, other than to ask obvious questions. Your apple access to methodology of iP4's video capture is itself useful information -- something that if I were a software engineer working on the various test projects here at XDA, I would want to know. Maybe that's something they could infer, or maybe its published somewhere, or maybe it's one of those "Geez, it's so obvious do i really need to be told that?" points.
That then gets blurred and muddied by the REAL armchair knowitalls (*I* disclose that I know nothing) who pounce on a pronouncement by someone here and say "That's impossible, or that's bullcrap, look here at my image, it proves you wrong, end of story" -- only to often find --- NOT end of story and that person got it wrong.
All i know is -- my experience has told me never presume -- because this site is SO HUGE, it is actually quite often that the right hand doesn't know what left hand is up to.
I wish there were a better means of coordinating the total knowledge holders of XDA site on this 720p issue regarding TOTAL CAPABILITY, software and hardware, so there is 100% collaboration. In the end, there is only one answer: Yes, desire can meet or exceed iphone4 720 p in every measure of resolution, or not.

Which is bigger? what is your initial inference? larger file size = higher rez?
thank you
roufianos cooked a Rom that achieved 29-30 fps but the phone restarted after 50 seconds of recording. Was that due to overheating of the processor? I don't know. His phone gave up spirit and he is waiting for a replacement so the development of his Rom is on pause at the moment.

Ive managed 26fps @ 720p with my Desire running official unbranded 2.2. Im using a Class 4 card, so that might help over your Class 2.
http://www.youtube.com/watch?v=saS39iqjDgs
I just compared the youtube clip to the original on my PC (i scaled the VLC window down to the same size as playing the youtube clip in its 'expanded' size) and there is definatly a small quality difference. The details on the original are noticable finer, so even @ 720p on youtube the bitrate must take a small hit.
Here is a screenshot of the comparison.

Hi guys.
I'm new here, so if I put this in the wrong category please correct me.
I got my Desire with the official Froyo update on it, and as many others I'm very disappointed by the 720p video, I get 24-26 fps on a very bright day and sound is horrible.
So I was wondering, are there any roms that gives you 30fps 720p and/or better audio?..
My phone is not rooted, but I will be willing to do it for a better phone experience as I'm very very disappointed..
This is my first Android phone..

Bad performance filming in 720p
I agree with you, Froyo is faster but filming in 720p is a disaster Stuttering performance!!!! How could they do this upgrade with no trying!!! Is ther any solution? I thinking to go back to my old HD2. TV programs looking back is still in a smaller view and not better than before...
Just wondering if there are any roms which have greater 720p fps?
Which is the best?
Thanks for answering.
the problem isnt with the roms, its with adreno the gpu! this is all its capable of, untill we find a way to o/c the gpu, its gunna have to do .....
It seems that sense roms are the main offenders when it comes to video stuttering, (not sure about sense HD as there is no camera yet).
OD, MIUI and Defrost all do not stutter for me, and record at about 27 ish FPS in good lighting conditions.
I can confirm that. Switched from LeeDroid to DeFrost and HD video performance was greatly improved!
Is anyone currently trying to figure out a way to overclock the GPU?
I want it too. But I think it is not so easy and safe (class 6 shdc? overheating..)

OK , I am new here, but this is what I think , where the problem lies.
A bit of background first:
A few months ago, when I got my Desire with factory 2.1 rom, I took some videos, at 800X480 . I have checked them today, they all are at full 25fps (I am in UK) , no juddering and very smooth. here is the interesting bit! the bit rate was an average of 2Mb/s for encoding.
Recently, after upgrading to Froyo, I realized that the video capture is awefull, so like a fool, I got myself, a new 16GB class6 card, tried it again, and same rubbish fps I got.
Then I noticed that now videos are being recorded at around 8Mb/s !!
I believe the higher bitrate recording is where the blame lies. nothing else.
I think, some clever sod, thought lets raise the bitrate to make it easier on the processor, but the extra bitrate, has caused problems elsewhere.

Then I noticed that now videos are being recorded at around 8Mb/s !!
I believe the higher bitrate recording is where the blame lies. nothing else.
I think, some clever sod, thought lets raise the bitrate to make it easier on the processor, but the extra bitrate, has caused problems elsewhere.

have you checked the codecs?
what one works best for you? mpeg-4, h.264 or h.263 ?
they are all as bad as each other.
It's because it saves the video to the SD card instead of internal memory and the GPU isn't the best so theyw ill always be jumpy.
But i thought it can do 720p only with 3GP, if it would use H.264 probably will get better result.
It has nothing to do with "saving it on sd card" and its write speed. even a basic class 2 card has enough write speed for proper operation.
My phone, on android 2.1 with a basic card could manage 800x480 @25fps easily, but on Froyo can not do the same, nevermind 720p.
something has gone wrong somewhere with the camera, and I'll doubt if it ever gets fixed.
After all, how else could they push new models with better capabilities, if older medels performed just as well ?
On a different note, for those who are not aware, 3GP is container format, not a codec! just like AVI or MKV are just containers. within these containers you have various components such as video, audio subtitles etc. H263 , H264, Divx etc. are all derivatives of Mpeg4 video codec. To make matters more confusing Mp4 is also a container and not the same as Mpeg4!! Just as Mp3 is not the same as Mpeg3!! ( to my knowledge mpeg3 was abandoned). Just for your information.
I just shot a small video clip today with leedroid, was stunned that 720p was unusable if anything moved in the picture.
Well, didn't have time to think too much about it, so changed to 480, should increase fps, but did not, which means camera is useless if there is any faster than slow movement in the picture.
My old ericsson t650 could do 30 fps nightshots with modified camera driver, so kinda expecting a desire should at least do 30 fps nightshots with 480p
Has there been any update on this, or still waiting for someone to figure out how to hack the camera?
