    Default iphone 3gs HD video recording on ios 6?
    Hi All,

    The iPhone 3gs HD video recording runs on ios4 and 5.
    Does anyone know if it works on ios6 as well?

    The folder where you need to copy the modified files is not available on ios 6:
    System/Library/PrivateFrameworks/MediaToolbox.framework



    Thanks

    Now it's //System/Library/Frameworks/MediaToolbox.framework/N88/AVCaptureSession.plist but it's not working like on IOS4&5. The only things I managed to change are Min FPS and bitrate. But if I change anything about the preview, sensor or capture resolution the shutter animation doesn't "open" anymore for movie capturing and during the recording besides the issue that I cannot see anything on the display, the phone is also super slow.

    That's already a big step. Can you please write down how did you manage to do that?

    1. Goto //System/Library/Frameworks/MediaToolbox.framework/N88
    2. Make a BackUp of AVCaptureSession.plist
    3. Edit AVCaptureSession.plist
    4. AVCaptureDevices ->AVCaptureSessionPreset640x480
    <key>LiveSourceOptions</key> -> <key>MinFrameRate</key> - Change from 15 to 25
    <key>TemporalNoiseReductionMode</key> - Change from 1 to 0
    <key>VideoCompressionProperties</key> -> <key>AverageBitRate</key> change from 3500000 to 5000000
    <key>VideoCompressionProperties</key> -> <key>DataRateLimits</key> change from 10000000 to 2000000
    <key>ProfileLevel</key> -> <string>H264_Baseline_3_0</string> change to <string>H264_Baseline_3_1</string>
    5. Same changes for AVCaptureDevices ->AVCaptureSessionPresetHigh

    This is what I changed based on tutorials for IOS 4 and 5.

    Thank you.

    Is it possible that you left one "0" character from the 2000000?:
    <key>VideoCompressionProperties</key> -> <key>DataRateLimits</key> change from 10000000 to 2000000

    The edited number should be bigger than the original?!

    yes, sorry, it's 20000000. it should increase the bitrate for higher quality.

    Here is the updated plist for higher quality video recording, if anyone needs it:

    AVCaptureSession.plist
