Render Profile Parameters - How to read them
The parameters that go into a render profile derive from the ffmpeg program.
This is a worked example to show how you can understand what these parameters mean using the ffmpeg documentation.
In the example above the parameters are:
f=dvd vcodec=mpeg2video acodec=mp2 b=5000k maxrate=8000k minrate=0 bufsize=1835008 mux_packet_s=2048 mux_rate=10080000 ab=192k ar=48000 s=720x576 g=15 me_range=63 trellis=1 profile=dv_pal_wide pass=2
Looking up the ffmpeg help translates these parameters as:
a main option is
-f fmt force format
video options are
-vcodec codec force video codec ('copy' to copy stream) -pass n select the pass number (1 or 2) -b bitrate set bitrate (in bits/s) -vb bitrate set bitrate (in bits/s) -s size set frame size (WxH or abbreviation) -me_range <int> E.V.. limit motion vectors range (1023 for DivX player) -trellis <int> E.VA. rate-distortion optimal quantization
audio options are
-acodec codec force audio codec ('copy' to copy stream) -ab bitrate set bitrate (in bits/s) -ar rate set audio sampling rate (in Hz)
The AVCodecContext AVOptions include:
-b <int> E.V.. set bitrate (in bits/s) -maxrate <int> E.V.. set max video bitrate tolerance (in bits/s) -minrate <int> E.V.. set min video bitrate tolerance (in bits/s) -g <int> E.V.. set the group of picture size
So all the render profile options are documented here in the ffmpeg documentation.
