Hi all.  
Not sure if this is the right place to post my question…  
I need to be able to convert video file to MPEG4 to suite NTSC with h.264 codec for video and AAC codec for audio, but I can’t seem to find a proper key values to use with the convertor…  
It should be smth like this:  
ffmpeg.exe -i sample.avi -ab 64 -ar 44100 -b 1248 -r 30 -ac 2 -acodec aac -vcodec h264 -target [COLOR=darkred]ntsc-svcd[/COLOR] test.mp4  
(The selected key is for MPEG2… it should be something different, but I didn’t find what…)  
TIA.
