Video Formats

So I'm going on a trim over the weekend and I'm just wondering what to set everything for Converting a video.
.WMV is a no brainer for containers but what about the Audio & Video What should the BitRate and Sample rate be set as?
I left the Defaults and its sorta big...and needs to buffer ever 30-60 seconds
Current sets are:
Video:
.WMV
320x240 - 29.979FPS - Bitrate 4000Kbps
Audio:
Bit rate 198Kbps - Sample rate 48000Hz
Stereo
With that The video is great quality, and GREAT audio but kinda skippy
Also The phone:
3VO 3.00 - 6.5
Omap clock is 240Mhz
30.60MB left on Flash and Videos are stored on 2Gb Kodak SD with 19.75MB free.
Thanks guys.

There is quite a bit of data on this topic if you searched "bitrate" on the forum.
From [ http://forum.xda-developers.com/showthread.php?t=518749&highlight=bitrate ], I gather that the best way is :
timepassman said:
i encode them in avi using virtualdub or tmpgenc
bitrate 288, 2 pass encoding,
320x 240
for proper aspect ratio use this
http://andrew.hedges.name/experiments/aspect_ratio/
put source ratio, then put 320, get the 4th parameter !

.mp4 is the best to use to recode good quality films for dash @ 320 x 240, just keep the bitrate low, mono sound about 92kbps will keep the size down.
You can use SUPER © http://www.erightsoft.com/SUPER.html it's free.
I use A-One FLV to AVI as i use it for YouTube but will encode any file to .mp4.

You could probably find more by searching (as I only skimmed the results). But these should help some.

AAC enable in Froyo?

Hi all,
Is there any way to get AAC encoding working in Froyo? So it can be used for video recording?

AAC stands for 'Advanced Audio Codec' and it is used to encode the audio stream in Froyo too. The bad news is that the codec settings in 2.2 where pushed too low and that's the reason the sound in video clips to be such low quality. I don't think that there is a way of changing the settings.

According to the media_profiles.xml file in system/bin, video recording actually uses amrnb codec for audio, which is a terribly low quality sound. From what I have been able to find out so far, AAC isn't actually enabled in Froyo at all. I tried editing the media_profiles file to enable AAC for video but it doesn't seem to make any difference...

This is what MediaInfo says about a video I shot while Gingerbread wasn't released yet.

I don't know what it says in the xml files - the fact is that the files are encoded with aac but the settings are so low that the result is just terrible.

These are the settings from a video shot with Gingerbread:

As you can see both the bitrate and the sample rate are higher which results in better quality, but the codec is virtaly the same.

You're right
Thanks for that tkolev - very interesting. I guess I should have checked that myself first. You're quite right, it is indeed very low quality AAC.
So question is, how to change the AAC encoding settings in Froyo. Doesn't seem to be in that media profiles file, because AAC encoding isn't even mentioned in there...

I don't think you can do that. Upgrade to GB is the only way I know of to get better sound in videos.
EDIT: Actually the stupidity of limiting the sample rate to 8 khz led me to believe that HTC used a microphone with a very low frequency response because that's the only logical reason they might have in using such low settings. Fortunately this is not the case.
Sent from my Desire HD using XDA App

LGCamera
Just as an update to this. I found the solution to the sound quality problem in video in froyo roms. A camera app called LGCamera. You can set everything the way you want it, including bitrate for the video, and file format (eg MP4 rather than 3gp), and also crucially AAC sample rate and bitrate for audio. Very nice. Video quality seems to be at least as good as stock app, possibly slightly better. This is at 8mb bitrate, haven't tried the higher bitrates yet....

does aac work on lgcamera on froyo?

[Q] CM7 Video resolution settings

I have a issue with the video recorder in CM7. I had this in RC1v2 and also in latest nightly, don't know in versions before that.
I can't use the high and youtube resolution setting. I can select them, but when I press the record button nothing happens. The other settings, for example wide, do work.
Is this normal? If not is there a sollution to solve this?

I installed Nordic rom and reinstalled CM7 latest nightly, that didn't solve my issues.
However changing the frame rate for the encoder profiles (in media_profiles.xml) to 24 did. (this was a suggestion in the developers forum). Now I can use all resolution settings.
My defy has red lens.

During testing I also noticed that the standard bitrate for the high and wide recording setting are really high.
For a 640x480 (high) mp4 video it is 10000 kb/s
For a 848x480 (wide) mp4 video it is 8000kb/s
This a lot higher then most good looking xvid 720p movies I have , which are around 2000 kb/s.
I now use 1300 kb/s (high) and 1500 kb/s (wide) which seems to give usable results but with a lot smaller videos.
Which settings do other people use/suggest?

Try the newest LG Cam (free) from market an set it to these parameters:
video resolution: 848x480
video encoder: mpeg4
video file format: mpeg4
video bitrate: 8
video framrate:24
audio encoder: ACC
audio samplerate: 44100
audio bitrate: 62900
and check force autofocus before capture
This works great on mey Defy (red lense)!

Can Oneplus 3 Play HEVC x265 1080p 10bit 30FPS Videos in HW/HW+ Mode?

Questions for all the OP3 Users. Can it play HEVC x265 1080p 10bit 30FPS Videos in HW/HW+ Mode on MXPlayer?
Are there any Artifacts or it lags and sttutters?
i have been Asking This question but only 2 OP3 users have replied.
One says it cant play in HW only SW mode. Other Says It Can on Stock ROM.
If Few more users confirm it does or does not, then it will help me decide to buy this one or Le Max 2.
Please Reply.
Thanks in Advance.

I played h.265 videos encoded in 10bits and 1080p23 through the stock video player as well as mxplayer with HW and HW+ modes. I also played a 4k 60fps 10 bit video used to showcase the samsung 4k tvs with no issues what so ever. HW playback yet again. Both on the stock ROM and kernel.

Mine on stock Oxygen ROM.....10Bit x265 CAN'T play in HW/HW+ mode...only in SW.
However, 8Bit x265 CAN play in HW/HW+ without problem.
EDIT: Got mine solved now my OP3 can play x265 10bit video file in hw+ .

Can you play x265 10bit in mkv format in hw/hw+? Mine cannot..Dont know why.

Yup, it can play tested with jellyfish-120-mbps-4k-uhd-hevc-10bit.mkv 438 MB http://jell.yfish.us/media/jellyfish-120-mbps-4k-uhd-hevc-10bit.mkv
and with jellyfish-100-mbps-hd-hevc.mkv 100 Mbps 365 MB http://jell.yfish.us/media/jellyfish-100-mbps-hd-hevc.mkv
give some links with vids that OP3 cannot play so I will check on mine, my op3 have all stock, no root.

Nevermind....I get it play fine now in hw+. All I did was to change the mkv extension of the 10bit x265 video file that refused to play in hw/hw+ to mp4. It played fine in hw+. Change it back to mkv...it also play fine in hw+. Now all my x265 10 bit mkv can play in hw+. Weird!!

Thanks Everyone.
I think i will buy this.

sorry for jacking this thread, but can anyone try hi10p h264 in this phone? I want to know before getting this phone.
I'm currently on zenfone 2 which is x86, no problems with h264 hi10p.

Short answer would be "yes, as long as it's not 4k".
For the long version, it depends on several encoding characteristics. These are video grain, bitrate, framerate (taking anime into consideration, there shouldn't be any 60fps releases so it's okay), chroma subsampling (4:4:4 and 4:2:2 being more CPU intensive to decode than the usual 4:2:0) and colour space (BT.601 and BT.709 are more widely supported and easier on the CPU than BT.2020, but you'd need a beast of a desktop CPU to software render anything in the BT.2020 space anyway, not a mere phone).
If the SSA subtitles are heavily animated, you can't do much about it. You'd need to find a video player on android that can properly render it, or hope that overclocking the phone might reduce the subtitle lag. Testing the file you linked on the MX Player 10-bit playback topic, it seems that the CPU usage doesn't increase by much with the subtitles flying around the screen, but the delays are noticeable while MX Player struggles to render them. It ain't as bad as you might imagine, as there aren't many dropped frames, but the frame representation is delayed severely. As a sidenote, reducing the rendering quality of the video doesn't affect the subtitle rendering lag in any way.

Tried that one. It's bloated and the noise levels are over the top. Simply put, it lags during high bitrate scenes, doesn't during lower bitrate scenes. It is rather watchable with just a few dropped frames if you lower the colour format from YUV to 16 bit RGB and use speedup tricks which butchers dithering and makes the video blocky with visible dither artifacts. Even so, the processor usage sits usually at 100%
I've also tried: http://coalgirls.wakku.to/657/evangelion the first movie in 1080p.
It works fine, colour format YUV with no speedup tricks. The processor usage jumped between 55 and 90%. Do note that this has only ~17Mbps bitrate. I think that 40Mbps is a bit farfetched as well as useless on a screen this small. Fortunately, most encodes have more reasonable bitrates, so it shouldn't pose much of a problem.
Tested on arter97's CM13 + kernel using MX Player Beta 1.8.6. This also means the processor had stock clockspeeds. For 10 bit h264 decoding, Samsung's Exynos 8890 and Huawei's Kirin 950/955 should be a little better than Snapdragon 820. I don't know by how much, but you should take note that the Galaxy S7 had its codec support gimped by Samsung (specifically, it lost 10 bit h265 decoding) after a certain update for both Exynos and Qualcomm versions, and I am not sure about the current codec support of HiSilicon chips like the Kirin.

mean/average bitrate of that movie must be near to (((18823.5 * 10^6) *8) / 7200) * 10^-6
or 20.91500 Mbps
try this one
http://coalgirls.wakku.to/6368/nisemonogatari
^
try that, just get the
Code:
[Coalgirls]_Nisemonogatari_OP3_(1920x1080_Blu-ray_FLAC)_[948BD021].mkv
(((458.18 * 10^6) * 8) / 90) * 10^-6
40.7271111 Mbps on average.
^ my zenfone 2 decodes that file with no problems, given that its an x86 architecture rather than arm.

Using YUV there are a few dropped frames between 1:20 and 1:27, otherwise it's a flawless playback. Using RGB32 there aren't any visible dropped frames during the entire run. I've tested it several times. During those 7 seconds, the processor stays at 100% usage, otherwise it sits around 80-85%. Understandably, the phone gets hot and the battery drains like mad.
I don't think sustained playback at these levels of processor usage is good for the device.

[APP] OOS 9.0.3 (Android Pie) Stock Camera

In general, after factory reset, Pie looks nice on my OP3.
Nevertheless, I have no idea what has happened to Stock Camera app?!?!
Compared to previous versions, half of the settings and options are missing.
Is there any info about what's turned on, off, image quality, slow-mo, image stabilization modes...?

Hi.
Ever since I have bought OnePlus 3 I have been using superb 4K recording.
For many years, it had crisp-sharp details utilizing ~56Mbps for video.
Unfortunately, only now I have found out that for a last year or so recordings are using 32 - 42Mbps and I have so much blocking in videos all the time. Such a destruction of the thing which worked so well.
So does anybody know when exactly has OnePlus destroyed 4K recording? For me it seems that videos up ti Jun 2019 were fine.
Is there any way to revert to back to 56Mbps?
Thx.

sure i can make a magisk module for that but was it really 56 mbps?
but if you use hevc instead you will get 56 mbps worth of quality in 40mbps.

acutally hevc just consumes less mbits than avc to give the same quality as avc at half the space. and hevc might use more processor for the compression. but if you still want it in the avc and at 56 mbps then i made one at my thread, go try it and tell me if it works.
