Any devs looking at the possibility to record movies in fullhd, 1080p ? I seem to remember I read somewhere that it should be capable of it.
Well if it is capable of recording in full-HD then why wouldn't Samsung themselves implement it so to make more sales?

Are we talking about the same company that decided to use rfs filesystem and use reserved memory thus limiting available ram... not to mention the weak wi-fi reception / gps issues.

Exactly my point, there could be a thousand of different reasons. But maybe our devs inhere are a bit sharper than Samsung themselves...
People have made mods that claim an extra 20 - 30 megabytes of RAM. When these are applied problems are noticed with 720p recording. Imagine the ram usage for 1080p. I don't think its worth the hassle.
1080p used in mobile phones do you think will be much better?
come on!
i dont think so...
Especially since the audio is still bollixed... if they fixed that first.

Dont think it need it.
First if hardware permit to record 1080p stream the 5megapixels chip wont manage to provide 1080p frames with a decent framerate.
then if it could the optics wont be able to resolve the resolution gain.compared with n8 nokia or iphone 4 720p output you can see what there s place for improvement in this way(sharpest optic and better sensibility)
but may our dev can work on compression level to keep more fine detail , sensibility management or faster autofocus without resolution change.
think this is the only reasonable improvement we could expect by software mod
Well, I have problems with 1080p playing, let alone recording.
Anyway, the hardware is 100% capable of 1080p recording and it would be really cool if some can mod it.

Hummingbird is capable of 1080p hardware decoding/encoding. It's equipped with hardware encoders/decoders. Both of them require decent amount of RAM reserved. I think that was the issue.
5mpix sensor is perfectly capable of delivering decent framerate @720p, why wouldn't it be capable of 1080p?
Resolution is enough, there might be bandwidth limiting factors between sensor-CPU.
Optics is perfectly capable of making quite sharp photos @5mpix, why wouldn't it be capable of shooting just 1920x1080?
There will be no software mod enabling 1080p recording, without hacking into hardware codecs/drivers.
Even if the framerate would go down to 15-20 fps, I would personally really like this feature. Some moments are best captured in highest resolution possible. An idea about the memory could be to allocate needed amount on demand, thereafter releasing it again?
Thanks for confirming that our Galaxy S is indeed hardware-wise capable of recording in 1920x1080.
Actually, why 1080p? It doesn't NEED to be 1080p. Why can't we add support for 800p (800lines vertical res) or even 960p.
We keep thinking about making the jump to 1080p, but is there any reason why would couldn't ramp up the resolution higher on the camera? Just because your TV expects 720p, doesn't mean computers do when playing it back...

800p and 960p are not common, so it would make things awkward. Can't play it on a 720p screen and not properly on a 720p screen.
BTW although noticable I don't think the difference between 1080p and 720p is that big. So I don't think anyone would really notice the difference between 720p and 960p and if so probably more as a placebo than a real difference.

I agree on the odd formats. However, going from 720p to 1080p is a significant improvement, especially if you have a large ( 46" + ) flat panal to view things on.
I would be very interested in this. And for everyone saying its not needed, this is a development forum. Many many many things that are done are "not needed" but still pretty cool. He asked if it could be done, lets stick to if it can, not if it should.

720 from 5 meg camera is already seriously pushing it, almost hack wise. Normally only 8 meg cameras should support it. And im not speaking about 1080...
The sensors usually can't deliver 30 fps at 1080p even if the hardware can encode it (which ive seen no tech specs of,just various "web claims" aka moot stuff)
It's not because its a 5MP sensor etc, its about how much data can go through the sensor after it's captured (that's before the CPU/DSP!!) You have very good 5MP 1080p cameras, because the sensors can handle it. They also cost more. I highly doubt the one in the SGS can handle much more than 720p at 30fps.
i'd rather have the image processing improved than 1080p, since 1080p (if it could be done that is) will be approx the same quality as 720p, use twice the space and need twice the power to decode on other systems.
in fact even the encoder can maybe be optimized. i'm not familiar with the hummingbird, but the OMAP's have TI's own such hardware codecs and while its proprietary you can implement your own codec accelerated by the DSP.
HummingBird's codec produce "very average" 720p H264 mainline (i believe?) at 10-12mbits (!)
Compare with x264 4mbit 720p H264 high profile quality for the same source, it blasts it away quality wise and is 2/2.5x smaller in file size. besides it has a zillion options depending if you want quality, latency etc.
bottom line, if a genius would accelerate x264 via the DSP it would be awesome.
I know the x264 team worked on the OMAP DSP with little success, mostly due to rather cryptic documentation
There are plenty of PC displays which AREN'T 1080P (only cheap ones). 1080p and 720p is optimal for TV's, but not computer displays. There are plenty of computer displays which are 1200 lines vertical resolution.
And I've found a difference between 720p and 1080p, but it's more obvious on larger displays which supports higher resolutions
I'd rather have slow-motion and a proper app that enables video editing/cutting/sound mixing just with Iphone 4.

I'm inclined to agree, theres room for improvement at 720p, its like the same logic as low end cameras and camera phones alike ramping up the pixel count doesn't directly mean better quality..
Plus the phone although it should be able to currently doesn't like playing back 1080p videos...
I'm not saying everyones going to want to watch 1080p on an 800 x 400 panel, just saying you might want to play back what you've just recorded to see how its come out..
i think someone talked about this before but i can't find the thread in searches. is it completely impossible to get 720p video out of the milestone?
likely possible, just depends on how many frames you would like per second...
The camera seems to be high enough quality to capture the pixels you require but the phone may not be able to process/compress the video stream, given the frame rate you may desire.
I'm not totally sure, but I imagine that's going to be the overall consensus.
Cannot be done.
I believe the phone itself couldn't keep up.
No enough hardware for 720p on milestone

I believe once you root the phone and overclock the hardware, it should run video at 720p

is this true?
how would u go about enabling 720p video recording?
that would be awesome!
i have already rooted and overclocked to 900mhz
I don't know if is it possible since we can't even play 720p .mkv videos, which I believe needs less cpu/ram power than recording 720p videos in high frame rate.
Furthermore, Milestone's camera isn't that good at all, why you would want to record a 720p video with a bad camera sensor?
with camera.apk change this is possible?
Playing 720p files is perfectly possible, but recording, hmm maybe at 24 or less FPS so why bother I prefer D1 at 24+ FPS, than laggy 720p,
It should be 720p video recording min requirements are 30 fps rate. Nexus one at best have 25fps. Our phone runs from 30 without root even motorola has specs sheet.. I think it was Verizon who told Motorola not to add 720P video recording. Just to make users upgrade to Droid Incredible and Droid x . In the Froyo update to Droid Last Summer. Milestone will get 720 p video recording in the new update 2.2 os in Europe. You can always talk to Matt from Motorola to verified my statement.

Hi cry3200, could you tell me how do you play 720p .mkv videos??
It's the only thing I wish my Milestone could do and can't get it done. My videos don't play flawlessly whatever video-player/settings I've tried.
I only get 720p+ videos and I would love to play them in my Milestone without having to encode them in lower quality...
Hi there,
first off all i don't need this feature on my phone...
It doesn't make sense to me if the video resolution is higher than the display resolution.
Anyway, no doubt it is quite interesting thing from the technical point of view.
At least some things should be fulfilled:
- hardware support for 720p
- enough bandwitdh on the memory subsystem
- application to handle HD video files
So i took a look into the processors datasheet:
Code:
· XGA - 1024 ´ 768 VESA timings at 60 fps (pixel clock = 63.5 MHz)
· WXGA - 1280 ´ 800 VESA timings at 59.91 fps (pixel clock = 71 MHz)
· SXGA+ - 1400 ´ 1050 direct drive of LCD with minimal blanking at 50 fps (pixel clock = 75
MHz)
· HD 720p - 1280 ´ 720 CEA 861-D timings at 60 fps (pixel clock = 74.25 MHz)
Looks like hardware would basically supporting this.
From my point of view the rest of hardware should be powerful enough to handle it as well (at least it is a SoC with PoP memory).
There's also a high speed connection to the display.
Last but not least the CPU is very similar too the one used on beagleboard.
AFAIK you may play HD on this hardware.
IMHO there might be some trouble on the milestone because of the resolution missmatch.
Please correct me if i'm wrong!
Regards,
scholbert

Just use VPlayer, set the quality in options to Speed or High Quality, and experiment with the buffer for different container types, MKV files should not exceed your card speed I use a class 10 card but the stock is a class 2, but usually I use MP4 720p files that I encode from MKV 1080p, I encode on the GPU so by the time I drink a coffe and smoke a cigarette its almost encoded, original MKV 720p has some audio/video sync issues with VPlayer so I dont use them, but if you overclock to 1.2 or 1.25GHz the sync problems are gone, I dont really remember a bit rate to tell you for encoding, but try with 2000-3000kb/s and see if it works I usually use between 3000-4000kb/s with my card
Just experiment,
EDIT: Forgot to mention, not all of the movies encoded play flawlessly but I'd say that 90 percent of them work, but keep in mind you need to overclock to 1GHz minimum so if you don't want to do that it wont work, and use FroyoMod cause its the fastest and most stable rom available, Gingerbread has problems with VPlayer it just crashes; but the problem is VPlayer itself
Thank you for your answer.
- The only reason i wanted this to work out-of-the-box is to not have to encode, etc.. Just copy the files in SD Card and press Play..
- I am always in 1.1GHz, I will try 1.2GHz..
- I encoded a couple of 720p .mkv files in MP4 with excellent (same I think..) quality with Handbrake and they played absolutely fine in Milestone. I just want to avoid this encoding process.
I will follow your advice and see what happens. First of all I guess I have to change the stock mSD with one faster.
Thanks for all the replies regarding this. I just figured that since the camera sensor has the pixels it should be able to fire out the extra res. I'm not concerned with the screen mismatch as the videos don't get played back on device, they get put on my computer and youtibe, both of which will benefit from the extra pixels.

Why cm10 camera cannot record continuously at 30fps?
be it 720p or 1080p.....frame-rate always drops in low light.
I want a camera which records at 30fps continuously irrespective of the lightning conditions...the same way we had on stock.
Why is fps issue there?It is similar to the one on HTC devices where fps drops in low light.
its normal behavior for lowlight conditions to have longer exposure shutter times during filming with small lenses in mobile phones

then why does it not happen on stock ROM?with LG stock cam flashable mod on CM7..continuous 30fps is available.then why not on CM10?
developers is it possible to make this happen?

higher fps @ night = darker videos.
There is a simple explanation here. The lower light means there is more noise in the video. With more noise the encoding engine has to put far more effort to get the compression it needs. However with low light unless the encoder has a denoiser the encoding engine has far more noise to deal with than normal conditions.
If you want a more technical answer: More noise means that the motion-estimation engine of the encoder is thrown for a toss. This is the part that consumes maximum CPU cycles. Hence the drop in CPU cycles.
There is another aspect here: The more the noise, the worse the compression and hence even other parts of the encoder are basically crunching more. More bits are generated which means that the encoding and entropy engines are also crunching more and hence the worse performance.
Generally in high end cameras a lot of noise is removed by the imaging pipeline in the sensor. However don't expect that in a mobile phone sensor. [This is the ISO performance that you see in DSLRs ].

I know that mates.
I don't care about dark videos or more grainy video
since in lowlight or "not the brightest conditions" anything below 30fps isn't pleasing to the eyes...especially fps of 15fps is a joke.
I'd rather have 30fps while sacrificing a bit of quality.
since the cm10 camera doesn't produce any super awesome video in low light by reducing fps
This should be super simple to answer, but I haven't found and answer, shouldn't csr 2 and nfs no limits run at 60fps? I feel like they did on my Galaxy s4, but I could be wrong.
Are these games locked to 30fps or is my phone not performing right?
Some games change graphics quantity depending on GPU/SoC combination. So you might get lower FPS on some games, but much better graphics, more shaders and higher texture quality and/or polygon counts.

That's kinda cool, but a bummer at the same time. I'd much prefer 60fps to max quality.
I tried to make a video in indoor light in 4K and 1080, 60 FPS, is there a reason why 4K is much less noisy? I did not think that resolution decides how much noise is there.
4K provides you with almost 4 times the resolution of 1080P thus you will most certainly see a difference in clarity.
In running a quick test, at 1080P on the default camera app, it captures the video at a bit rate of 20.0Mbits per second.
In contrast, at 4K @ 30FPS, it captures the video at 41.9Mbits per second.
So the capture size versus the bit rate is certainly going to play a deciding factor.
But there are other ways to achieve an optimal capture rate @ 1080P.
If Xiaomi gave us the ability to utilize the High Efficiency Video Coding (H.265) and dictate our own bitrate, you'd see better capture rates @1080P.
My only other suggestion would be to seek out a third-party camera application (GCAM perhaps?) and test further.

Is there an app that supports [email protected]? There is no point in recording videos [email protected] if there is 4K, but I like the idea of 60FPS.
