Picture / Video Formats Matter ?

I was wondering if the mb size of the photo matters ?
Some roms I get pictures that are up to 2.0 mb. Some don't even reach 1.0 mb
And also some roms record in AVI (Unity Rom)
Some record in 3gp.
Do these formats / size matter in the quality.

[DEV] media_profiles.xml modding (improve picture&video quality)

Hi,all .
I'm trying to modding media_profiles.xml for desire s because this thread
http://forum.xda-developers.com/showthread.php?t=1065992
(some time i use phone cam to record my piano so sound quality is important )
This is what i change from original file
Main Cam / Front Cam
Audio
- Change Audio Codec from amrnb to aac (for high quality)
- 2 channel(stereo)
- Increase Bit Rate to 128kbps and SampleRate to 44.1k
Image
- Change Image Encoding Quality to 100/95/90
Video
- Change height&width to match 720p size and bit rate to 17000000 for main cam
- Change height&width to match VGA size and bit rate 4000000 for front cam
Testing with VoidU S 1.1a it work perfectly audio in video improve a lot! and i can use stereo recordring now (stock kernel)
Feel free to test but! Don't forgot to backup original before use adb to push file to /system/etc
**seem to be not working with UnityV9 (Stereo Recording) but on stock kernal it work perfrectly!**

How strange, I was just modding this file this morning.
I was able to successfully mod the file too and improve audio quality in camera recordings, but what I actually want to do was improve the sound quality when using the stock voice recorder. Any ideas?

I just test with Unity Kernel. It seem like unity doesn't support Stereo Recording! :/

Is this fix possible to apply also on MIUI rom?

Can you not increase image quality from this file?

Fantastic video capture software found 1080p50 !! incl. GPS tracking

Hi all. I installed VideoRegPro and its fantastic. Gps track info on video or not. Fullhd up to 50 frames per second! Great resultat! Example on my youtube channel: youtube ..... user .... CREANOA

http://www.youtube.com/watch?v=g1kXLZWY8bY&feature=youtube_gdata_player

thanks I try it

Dear Friends,
Just tried demo version... Designed specially for in car video recording but seems really great for daily video recording... Higher frame rate and bitrate compared to stock camera... 10 seconds of 1080p video recording @50 mbs @60 fps takes ~20 mb... I am outside right now and couldnt transfer video to my pc to check the real results for bitrate and framerate of the recorded video... Thanks emu28 for the info...
EDIT:
Copied the recorded mp4 file to my pc... eEven the app settings are @50mbs and @60 fps, the result is really like stock camera but mono also... The recorded video has 24 fps and around 18 mbs... Better to go with stock camera but videoreg has different features for in-car recording; so not uninstalled...
Kind Regards,
Kind regards.

For me of course perfect, sensation for my youtube channel with car driving, now incl. Gps data... just waiting for next storms or so...

That's a neat app, I'll get it a try - thanks.

New test video, night, on my channel. Youtube/user/creanoa

They can't increase the FPS just like that without doing something to the firmware of the camera.

You do realise that that isn't mathematically possible, no?
10 seconds * 50 megabits per second = 500 megabits, which is around 62 megabytes.

[MOD] 2.3.6/7 Video Recording audio improvement -- WIP

Hi everyone
when you record a video on your original SGS 4G camera, your audio sampling is :
66 kbps bit rate.
16 KHz sample rate.
which is pretty lame...
If you ever tried to record live shows or concerts, you probably noticed audio is awful on recorded video...
Introducing Video Recording audio improvement MOD
found and very well explained by rafalense (http://forum.xda-developers.com/showpost.php?p=10980448&postcount=268).
Performed on SGS 4G camera by me. So, now recorded audio sampling is :
118 kbps bit rate.
32 KHz sample rate.
file size change is barely noticed.
Still camera is not modified.
I took, as a basis, the Team Acid modified camera - done by DSexton702.
So it is capable of taking pictures when battery is low and also by using the power button.
This is still in beta as :
1. Currently Audio-Video is out of sync. I need to check if this can be fixed by changing Video sampling rate....
In the meanwhile, you can fix this on PC very easily.
2. This mod does not use the media profile xml for greater video frame rate.
I actually put the original file back. I found the result to be not supported by all players and having some side effects like visual waves (and much larger file size).
3. Actually I examined DSexton702 media profile and it defines some various audio sample rates but always create 16KHz at the end.
If someone here has the knowledge in A/V synchronization or a good setup that works - please let me know so i will fix it.
Thanks.

Awesome work! Thanks.

Glad to have u aboard thanks for this man this is well needed!!!!!

Now having AntonX kernel supporting Vodoo Sound - I will test audio HiFi record option enabled on video recording and update.

Would love to see this become final. You certainly are right about the audio during concert recording. All we hear is pure bass... Thank you for working on a much needed video recording mod.

Yeah.. would be awesome.
Thanks for the work, itzik2sh.

Edit : guys working with Voodoo sound (with supporting kernel)
need to run the Voodoo sound app and choose 'Recording Preset' - then change default to 'Loud environment - with DRC'
This should improve the recording level of loud shows.

Hi
Did anyone here test this MOD with live concert recording ?
If it doesn't help than I'll drop all further work.
I thought this problem is SGS 4G unique, but it turns out it exists on all Sammy phones,
even Nexus and SGS 2. See this bounty thread for SGS 2 :
http://forum.xda-developers.com/showthread.php?t=1172048
and this :
http://forum.xda-developers.com/showthread.php?t=896826
I'll try to ask AntonX to take a look or maybe ask supercurio on kernel implementation...
I also tried installing LGCamera from the market, which supposingly has an audio gain control, but it fails to launch and I had to uninstall it.

Nice improvement

After voodoo digital recording, video and audio are repacked and converted to the device analog sampling rates, that this tweak changes (but also unsyncs)...
So if you have the time and effort, I'd appreciate if you share your experience with us all.

Help with recording constant frame rate video on the HTC Desire S

I have been trying to get the most out of the camera of my HTC Desire S in terms of video quality, and now I am able to record 720p [email protected] Mbps. The vanilla camera app(rooted stock 2.3.5 ROM) records [email protected], so it is nice improvement.
I am using an app called IgCamera, it has lots of options for customization(bitrate, frame rate, codec, etc.), and I have modified the /system/etc/media_profiles.xml to increase the H264 encoder bitrate cap. It was set to 8Mbps in vanilla, I bumped it up to 24Mbps, but I have found out, that the maximum bitrate the phone can handle is 12 Mbps, any higher and the camera app freezes, and the camera cannot be used until reboot.
Now, I am looking for a way to force a constant 30 FPS. Currently, the videos are recorded with variable frame rate, and VFR is nasty for any kind of video editing. I have tried setting both the minimum and maximum frame rates in media_profiles.xml, in the encoder caps section(it seems to be the only one that affects IgCamera in any manner), but I am still getting a variable frame rate video.
Has anyone done something similar? I would appreciate any information on making a phone record CFR.
