Best Video playback settings/performance of Desire?

Dear Desire users, it's no doubt that one of the points of getting Desire is to use for movies playback, what's your best conversion setting found so far for SMOOTH and HIGH REG. playback?
I've tried various settings and found
Resolution: 720p
Avg. Video Bitrate: 3000k (2500k runs a bit smoother but with noticeable lower picture quality)
Avg. Audio Bitrate: 192k
running pretty well on short HD movie trailer. (just a slight lag while playing w/ HTC album)
Yet, I found Act1 player plays the same file a little bit smoother, is it my illusion?

If you are converting movies specifically to run on your Desire, why bother with 720p when the screen doesn't support that resolution?
I can only really understand it if you are converting for use on other devices that do support that resolution and don't want to duplicate the effort.

valid point Dave, however, some HD video sources I got got some real "wide" resolutions, such as 1280x532, having the aspect ratio of 2.406, the clip ended up with two black bar on the top and bottom of the screen, that's why I would choose to encode into 720p so that I would got much lost while Zooming in while watching~
besides, I've tried to encoded the same file with same bitrate (3000k), the file size only dropped from 59mb to 57mb, I don't know the reason but I guess the machine speed quite similar effort in rendering both clips right?
please drop some more thoughts guys!

I use the Nexus One defaults from Any DVD Converter:
x264
800x480
1200kbps
25fps
1 encode pass
AAC
128kbps/44kHz
Converting from 1080p source. Looks awesome. Wouldn't bother with higher bitrates, personally.

Isn't a 3000k bitrate massive overkill for a phone anyway?
I encode my video to iPod Touch presets on Handbrake, so my wife can use the same files on her iPod.
Playing these videos on the Desire is more than adequate visually even at a much lower than native resolution (for my needs at least) and the total bitrate is usually between 550kbps and 600kbps.

I personally wouldnt bother with converting. My crummy pentium m laptop wouldnt be able to convert it in a satisfying timeframe anyway.
still hoping that one point in the future a better ndk which would allow access to the gpu video acceleration will allow spiffy stuff like hd video (through coreplayer maybe)

Don't watch any movies on my PHONE, nor play music - it was never a point of me getting it so that statement is a bit off
Watching a film on a tiny screen is the last thing I want to do - besides, battery would die in a couple of hours

Dear Daern & Dave, I admit using 3000k is just kinda trying to test how far the Desire could take, smart people saying that even though the phone can handle it, the battery won't stay long for running massive data, 1200kbps might be just fine for the balance between quality/battery life. but besides battery life, it's absolutely glad to see our Desire could render a 3000k 720p video (without almost un-noticeable flame drops - tested with "bare-eye"). it's impressive. (while my Blackstone could only take around 700-900kbps.

Dear EddyOS, since there aren't too much driving in a tiny place like Hong Kong, movies/favorite TV shows could actually do me some good while riding on a train or bus. Meanwhile, catching some clips in the bath room while handling "big" business is also good.
yet, I have to admit that, I've been surfing multiple Android websites for news and tweaks, and Froyo whenever I got time. hoping that one day I would jump into a web telling me HTC had released its Froyo update for our new (but already old) Desire.

[Q] too many issues wih new DHD

Guys
I have had HTC phones for a long time and generally beed happy eith them .
This in not true with my new DHD.
I have alist of issues and want to know if they are hardware or software.
Rubbish speaker - much more tinny then Hero
Low volume - less the Hero
sometimes no volume
can record HD video but cant play back on phone
now video app bombs out when trying to record HD video.
HD recording is atrociuos
My girlfriend got the samsung galaxy S ( smaller hands- smaller phone)
and its much better, even plays flv
Could this be a Hardware fault or have peeps managed to resolve this with different roms?
Your help is much appreciated

The quality of the speaker is hardware caused. Nothing you can do about it expect not using it. Seriously, I think it's not meant for listening to music with it. I always use headphones or my PC to playback video.
The volume is low, I was also very disapppointed with it especially as I was almost unable to listen to audiobooks while being outside with my headphones even though volume was to 100 %. Good news is, there's a solution: Get a custom ROM like Revolution HD. It boosts the volume. I also got 16 Ohm headphones and now I have the volume down to 30 % where before 100 % wasn't sufficient.
Of course for flashing a custom ROM you need to root/s-off your phone. But there are 1-click apps for this fortunately.
And for playing flv, I never tried it but there will surely be an app that can do it. Same for HD playback.
But you have to consider, even though your girlfriend's phone plays HD the display still doesn't support HD resolutions same as the DHD doesn't. So the video will have to be scaled down. But I'm pretty sure there are apps for that problem as well.
So bottomline, the speaker quality and HD recording quality is something you have to live with. All else can be dealt with by apps/ROMs.
And if you're really not satisfied, you might consider returning the DHD and getting a Galaxy S. Both are great phones and it can well be you'll like the Galaxy more.

RockPlayer plays pretty much every format FFmpeg can decode. Sometimes it is a bit buggy though, like sound out of sync, but nothing major. I suggest you give it a try.

There are thousands of flash players on the market that can play flv.... and there is not one phone in the world with the screen resolution for HD playback. lol

I read that it won't play the HD recorded video back very smoothly because of the cheap and slow SD card they give you with the phone.
Try a faster good quality SD card, Class 6 should work better.

How much space do you have left on your s3?

How much space do you have left on your s3?
16GB S3
4.5gb remaining
What do you have on there that takes up the most space? I cant find an app where its easy to see exactly which files/folders are taking up how much space

My 16GB is almost full, and the culprit is mostly GameLoft gamedata.
I definitely want at least 64GB internal in my next phone, + 128G external, and 1080p flexible samoled+, wireless hdmi, ~5", 12MP, ... better stop myself here.

1080p comes in handy when you connect your phone via MHL-HDMI cable to a 1080p display. Currently, WhatYouSeeIsWhatYouGet, which means 720p upscaled to 1080p. Also, if you've got eagle eyes, the S3's 320dpi still isn't good enough.
In any case, 1080p displays are coming, along with GPUs efficient enough to drive 'em. At some point we'll have to make a disconnect between the phone's display resolution and it's output resolution (when 4K and 8K TVs become more common in a few years).

You have eagle eyes? It depends how far you hold it from your eyes as well. There will most likely be no difference - except for people that like to think they see the huge difference while they are staring like -
I know 1080p is coming. There is lots of things in the world that are unnecessary so I didnt doubt it for a second.

zmore said:
My eagle eyes comment wasn't the main point, but thanks for choosing that for your subtle diss launching pad.
Both you and I would be able to tell the difference, and not just "like to think" we would. At 1ft the human eye starts reaching its limit of seeing individual pixels @ greater than around 300dpi. I often hold my phone 6 to 8 inches away and can easily see jaggies, so, until we've actually reached the physical limits of our eye, moar dpi == moar betteh. Kthxbai.

Not sure where you interpreted a diss launching pad from.
There are many web sites discussing this topic. I dont need to get into the specifics (especially since this is partly my field of work).
1080p on screens this size is pointless.
I am now asking you nicely to stop posting in my topic. If not, I will report to moderators.
Thank you.

zmore said:
400+DPI may be pointless for MANY people, but definitely not everyone, including the millions of us with exceptionally good eyesight (20/15 or 20/10). For those with regular 20/20 vision, they'll get the better display anyway, and primarily take advantage of it when it's natively output to a matching 1080p display instead of upscaling from 720p (which was my main point previously).
AND NOW I SAY GOOD DAY TO YOU SIR!

My point was 1080p is pointless for the SMARTPHONE's screen. Obviously not for a 1080p external display (which still has its stipulations - depending how far you are sitting, etc).
Regardless, I have reported you.

None... I have to use a backup SD Card and that's almost full. I have mainly music taking up all if the space. Second is apps and the photos.

Any chance at 24 Hz (24p) output?

It's a bit frustrating that none of the major streaming devices (Fire TV, Apple TV, Chromecast, etc) support 24 Hz video output, and this despite indications that the video chips used by these devices are fully capable of it. It's as if no one working at Amazon, Apple, or Google care a lick about video quality and preserving the native frame rate of most films (24 fps). Hell, the Boxee Box supported 24 Hz output. From what I've heard the Roku Stick does as well, though I'd love it on a device a bit more open such as the very hackable Fire TV. Which leads me to my question; have there have been any in roads made in unlocking 24 Hz video output with the rootable Fire TV?

im at a loss here, what is the problem? i have seen a wide variety of video formats and have yet to have a single problem. i assume the firetv is running at 60hz? i may be wrong but that means it can play anything from 1 to 60 hz smoothly. so whats the big deal? if anything running a higher hz would mean a smoother animation?

no offense, but I was actually going to make a comment in my original post along the lines of, "if you don't know what 24 Hz output (24p) is or why it's important, then don't bother responding". Obviously nothing against you personally, it's just that I've seen 24hz/24p related threads on other forums (Plex, Roku, etc) and they quickly get sidetracked into an explanation of its benefits and why it's important. Google is your friend for that.
But just to summarize, most movies (and even many modern TV shows) are filmed at 24 progressive frames per second. When outputting a native 24 Hz video at 60 Hz, the device must fill in the gaps to "magically" create 60 frames/second out of just 24. And since 60 is not an even multiple of 24, the process is far from ideal. This results in judder or non-smooth playback, which is most noticeable during slow panning scenes (can also be seen quite easily on scrolling credits). If you find yourself saying "well every video I've played looks good". Well, this is case of "ignorance is bliss". Watch a movie on a projector at 24 Hz or a 120Hz TV that accepts 24p input (120 is a nice multiple of 24, so each frame needs to be merely replicated 5x) and you'll see the difference with your own two eyes.

well at least you said no offense...
but IF the hardware is capable, unlocking 24hz shouldnt be a problem IF they manage to make custom roms for it
*i just watched a blueray on my 72hz monitor (3x 24) and then changed it to 60hz, sadly i saw nothing different, perhaps my fast computer does a better job at rendering. guess its one of those things that videophiles can detect that a normal guy cant xD

I have Amazon Fre TV and Minix neo x7. Minix x7 have 24hz output and video plays smooth without jitter or stuttering. On Amazon Fire TV all videos have jitter and stuttering this can be seen when picture is moving slowly from left to right and wise versa. I though that it's problem with with my Fire TV because I'm from UK and I bought Fire TV from USA. If I change refresh rate on Minix to 60hz I see the same jitter and stuttering.

Its not only the one refresh per frame that makes the movies so smooth when outputting with 24Hz.
Depending on your TV, it also smoothes the motions (inserting calculated frames between the movies frames) when the signal is appropriate (e.g. 24Hz).
Outputting at 60Hz, and probably even into the DVI-HDMI, usually results in the TV just showing the 60Hz it gets.
Oh btw did you use a movie player which allows to sync the movie to the refresh rate like MediaPlayerClassic HomeCinema?
I´m pretty sure the result wouldn´t have differed much though: 24fps, being in sync or not, are simply not enough for smooth playback of motion.
The Hobbit movies for example were filmed in 48fps (HFR(-3D)). This way one was able to see smooth motion even in the cinema. For home use you only get to buy 24fps BluRays - but your (reasonable good) TV does the smoothening on the 24Hz signal it gets from your BluRay player.

How to set 25fps?

So just got the phone a couple days ago... And im trying to figure out why im stuck in NTSC frame rates.
Im from the UK so obviously i prefer the look of 25FPS and when i do content I work in 25 fps.
It really seems strange that the cameras are arbitrarily locked to US frame rates.
Is there anyway to get 25fps?

Yes can be annoying. Cannot change it in the stock camera APP AFAIK. But other apps like Open Camera for example will allow you to set the FPS to 25fps.
It's likely just not as important as it once was... Unless you are specifically playing back on a older interlaced television set, than the chances are that item you are watching the video back on will support it regardless..
i.e Most phone, laptop and PC screens are running at 60hz, and most TV's will handle 24/25/30 fps intervals without issues these days.
Most people are uploading to youtube or online where by 30/60fps make more sense. 25fps is a leftover from the interlaced broadcast TV days. So the only difference it would make is if you shoot at 30fps and then need to broadcast it at 25fps, in which case you would have 3:2 pulldown.
The standard camera app does allow flicker/banding to be set to 50hz/60hz/Auto thus not to have strobing light issues.
But is there a specific reason you want to shoot 25fps and not 24/30/60?

Having worked in video production for much of my working life, I cant say i fully agree. While sure 30fps is common thats only because most content on youtube is from the americas where 30fps was common
It isnt just a hang on from the interlaced days either. A lot of american shows were actually shot on film at 24 and 25fps and then upsampled to 29.97 fps (or there abouts) 24 and 25fps have a more filmic and natural flow than 30/60.
Even today nearly all dramas and filmic shows in america are filmed at 24 and 25fps. With only soaps and news hanging onto 30fps.
Ive also tried open camera, even though the "option" is there, when i watch the footage it comes back at 30fps.
So its like its baked into the hardware encoder. Its really stupid though. Its not like its a limitation of hardware, not being capable of producing that frame rate because its too complex... Its as if just a config option or api is missing.

I'm from Australia where we also use PAL25FPS, because of 50hz electricity same as you in the UK, but any PC screen or monitor or phone for the last however many decades default is 60hz. Which is why 30/60/120fps makes more sense all around the world.
If YouTube was a British TV program being broadcast on TV, than 25fps would make more sense. But because it's being viewed on monitors, phones, laptops, tablets etc, than 30fps ensures no extra/interpolated/missed frames etc.

Motion pictures have always been shot at 24fps, but TV in PAL countries has indeed been shot at 25fps, while US (NTSC) TV shows are shot @ 30fps.

Ahh, I didn't actually test it, I just remember the setting... GCAM ports will definitely let you shoot [email protected] (as well as 30/60).

I agree the option would be good. But at the same time it's likely not as important as it once was. Many years ago I required 25fps for broadcast TV, but these days it's simply not required. I cannot really see a use case where it matters anymore.
It really is a leftover from interlaced fields, and now days screens are capable of progressive scan.
If you are intending on shooting for broadcast TV with this phone (which seems odd) you no doubt would be editing in post, and thus would convert the 24/30/60fps footage to match your 25fps timeline in post, which would automatically do a 3:2 pulldown or pullup to convert the frames anyway.
If they did offer 25fps, there would be lots of complaints from people wondering why their footage is stuttering and jumping, when played back on their phone, PC, Chromecast, Youtube etc... Which I think is why they don't like to offer it.

Sadly even the best 3:2 pulldown can cause ghosting and artifacts, but I also plan to do some VFX as well, so for things like tracking thats a real killer...
Also im sorry youre wrong many shows in america (assuming they expect to sell internationally) always shoot at 25. Startrek for instance was shot at 25fps on 35mm.
And also when rendering out FX sequences, that extra 5 frames per second really add up.
Id rather keep to 25 for the aesthetics, and the ease of workflow.
I wonder if the framerate is something baked into the firmware of the camera hardware.
