Hello.
What will give best quality of MPEG4, H.263 and H.264 when filming in 720p?
You cannot record with H.264 and H.263 in 720p mode. MPEG4 is your only option.
What will give best quality of MPEG4, H.263 and H.264 when filming in 800x480?
There is no general answer to that question. It depends on the encoding rate. Anyway, since H.263 was meant for less motion and for small bandwidth, I'd say go with H.264. But be warned: H.264 is a very performance hungry codec.
What are the proper settings for encoding video to MPEG4 for playback on the G2?
height 320?
width 480?
what should the video bitrate be?
what about the audio bitrate?
thanks in advance
Honestly I'm curious also.

try
MPEG-4 (H.264)
1000-1500kbps
800x480 default / 800x340 and 800x334 for wide screen movies, ect.
23.97 or 29.97 fps
aspect ratio should always be "auto" or "keep aspect ratio"
audio.. wouldn't go under 112k

First, as you all known, Touch pro2 can't record VGA video in H.264 format(the resolution is limited to 352x288), it's really a pity. And if you want a VGA res, you just can use a MPEG4 format and finally get a video full of noise and blocks...... After I buy my Touch Pro2, I always try to find a way to enhance the video recording quality. And finally found it!
If you have the software "BsB tweaks" in your ROM, you can see it has such two tweaks：
Video Format--Enable hidden video recording format
(Add H.264, Motion JPEG,3GPP2 to the format list)
Video BitRate--Improves Video recording in MPEG4
I should tell you that, this two tweaks is not useful on Touch Pro2 (I don't know if they have any effects on other phones).The first one makes you could record in H.264 format, but only with a resolution up to 352x288. The second one has no use at all.
But from BsB tweaks, I know that there're some Reg keys handle the video recording parameters, So I spend whole night on these keys, and find many interesting things
1.Enlarge video recording Bitrate and Framerate:
Value function
"HKLM\SOFTWARE\HTC\Camera\Recparam\<...>\<Bitrate;VSBitRate;FrameRate>"
These Reg Values control the video recording Bitrate and FrameRate, if you want to enhance the quality, you can write down a bigger number.
For example, change
"HKLM\...\Recparam\H264Large\BitRate" to 600000(dec)
"HKLM\...\Recparam\H264Large\VSBitRate" to 600000(dec)
"HKLM\...\Recparam\H264Large\FrameRate" to 20(dec)
(Tips: Large equals to CIF, Medium equals to QVGA, etc...)
then when you set the Capture format to H.264 and Resolution to CIF(352x288),finally you will get a *.3gp video at 600kbps(VBR)@20fps.
Now a new question comes out: what's the upper limit Bitrate of Touch pro2 to record a H264 video?
I have done the test and find out that you could record a H.264 video as high as [email protected](352x288) ! Maybe you have thought that MSM7200 couldn't be so powerful to encode 1000kbps H.264, but it really works fine！
So，if MSM7200 could support 1000kpbs bitrate，then it should have enough power to record a VGA H.264 video! Go next！
2.Crack H.264 VGA video record limitation on Touch Pro2:
Don't wasting time on the HTC video recording program, whatever you do finally you just can use the resolution no more than CIF(352x288) when H.264 format is selected.
Now the way out is here:"HKLM\SOFTWARE\HTC\Camera\P2\"
When I delete it, the HTC video recording program can't start anymore. Now you know, this Reg Key has the Values to decide which format and resolution the recording program should use
Value function
"HKLM\SOFTWARE\HTC\Camera\P2\CaptureFormat"
When set to "10(hex)", the video format is MPEG4 (*.mp4 V:MPEG4, A:AAC);
When set to "2000(hex)", the video format is H.264 (*.3gp V:H.264, A:AAC);
Other value not tested.
"HKLM\SOFTWARE\HTC\Camera\P2\MainCamCaptSize"
When set to "20(hex)", the video resolution is 352x288;
When set to "1000(hex)", the video resolution is 640x480;
Other value not tested.
PS: Check if there is a Key "H264VGA" in "HKLM\SOFTWARE\HTC\Camera\Recparam\", if you can't find it, please create it manually and copy all Values from "H264Large", set BitRate & VSBitRate to 1000000(dec) and FrameRate to 20(dec).
When you set CaptureFormat=2000(hex) and MainCamCaptSize=1000(hex),then start HTC Video Recording, you'll get a VGA H.264 video with great quality!
3.Try 1000kbps VGA MPEG4 video recording:
Besides H.264 format, you can also enlarge the BitRate (in HKLM\...\Recparam\MPEG4VGA) of MPEG4 formate to get a excellent quality MPEG4 video.
Compare between MPEG4(1000kbps,VGA,20fps) and H.264(1000kbps,VGA,20fps), I find that MPEG4 has a better quality on rapid motional scene, because it's variable bitrate is up to 1600kbps, and H.264 is limited to 1000kbps. MPEG4 also has a higher average famerate, act more smooth than H.264. On the other hand, H.264 has a strong advantage on slow motional scene. Altogether, MPEG4 has a surprising better quality than H.264 at 1000kbps VGA mode.
4.Attention:
1.Don't set the bitrate more than 1000000, if you set it as 1100000, you could find that the actual bitrate break down to 128kbps! That is why the BsB tweaks didn't work, it tweaks the MP4VGA bitrate to 4194304(dec) !
2.Don't set the framerate more than 20, or you'll get a less framerate.
3.MSM7200 handles MPEG4 and H.264 recording in HW mode, so lowering the bitrate is useless to get a smoother video. You just need to keep the bitrate less than 1000kpbs then MSM7200 will work best enough.
4.When you decide to record a VGA H.264 video, a overclock is recommonded. Just use WiMoSpeed to oc to 710MHz!
5.Don't open HTC Camera's setting panel in video recording mode, that will lock the H.264 VGA mode again and the resolution goes back to CIF!
6.Only tested on T-Mobile Touch Pro2 with EnergeRom, other MSM7200/7201 phones should work too.

Cab and Reg files for this topic:
Enable MPEG4 & H.264 VGA recording at 1000kbps: MSM7200_H264VGA_Tweaks.cab
Unlock the H.264 VGA limitation: vgaunlock.reg (included in MSM7200_H264VGA_Tweaks.cab, but if you click out the HTC Camera's setting panel and the resolution go back to 352x288, you may need it to turn on VGA again.)

OC to 768MHz？ I think this is too high for your phone, MSM7200 use HW mode to encode video, It's video DSP maybe unstable even while your CPU works fine.
If you have tried without OC, I would say that your phone really need a repair
And you could depress the clock lower than 518MHz,for example:400MHz then try again, maybe it works.
PS: Did you try EnergyROM?
Thanks!!! could you please post some video tests on YouTube?

I really want to do this, but there is a Great FireWall in my country which makes us can't visit YouTube, Twitter or Facebook, because there're many "disharmonious" information on such sites and we're "protected" by the Goverment...
But I could show you two video captures(my Laptop's desktop),left one on H.264 and right one on MPEG4, both has a 640x480 resolution and the bitrate as high as 1000kbps, I promise there're video's captures but not photos

From day 1 the hidden formats have never worked. I use BSB TWEAKS to show them but they just freeze my camcorder. This happens whether i am overclocking or not. Yes i have tried ENERGY roms but still nothing. Could I be doing something wrong with BSB TWEAKS? I ask because my friend has the same settings and these formats do not work on her device either. It would be great if I had the reg entries for HKLM/SOFTWARE/HTC/CAMERA so I could compare them to my registry.

Oh, the Default format of HTC Camera really sucks, here is my Camera.reg, pls flash the newest EnergyROM and import it then try again.
By the way, what's the version of your TP2? Mine is T-Mobile without the front Camera, maybe there is something wrong with your front camera Reg setting.
Check the Value "2ndCamCaptSize" under "HKEY_LOCAL_MACHINE\SOFTWARE\HTC\Camera\P2", try set it as 10(hex) or 20(hex).
Or hard reset your TP2, then only change the value "HKEY_LOCAL_MACHINE\SOFTWARE\HTC\Camera\P2\EncodeFormat" to 7FFFFFFF(hex), which add H.264, Motion JPEG and 3GPP2 to you format list (do not use BsB tweaks), and try again.
And, if you really can't use H.264 whatever you do, why not try a 1000kbps MPEG4, it has even better quality that H.264 in VGA mode.
So... what's the way to go?
install the CABs, do the reg edits, both?

Just install the CAB that's OK.
And you could also do the reg edits if you want to adjust the recording parameters yourself
The vgaunlock.reg is used to set the recording format back to H.264 VGA when you:
1.want to try another format (for example, MPEG4), then you want to use H.264 again;
2.click out the HTC Video Recorder's setting panel by mistake, this would pull down the H.264 recording resolution to 352x288.

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+ .

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.

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.

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.
