commandline avisynth --> mp4 (h264+aac) that plays in QT Player

[hanfrunz]

Hello everyone,

i am trying to convert a avisynthscript to mp4 (h264+aac) that will play without problems on quicktime player7.

Does anybody has a working solution It's just for preview movies (640x360@25fps@~1000kbit) so there's no need for highly optimized stuff, it should just play on every player and look "okay".

Ideal would be a ffmpeg commandline, because i use a batch-script to start the conversion.

thanks,

The only thing that caused problems when decoding with QT7 on my mac was qmin, I must make sure to set it to 4. I think it's something to do with hardware decoding. Otherwise you can opt for ipod compliance (the lowest common denominator?) and make sure you encode at level 3.0, baseline profile, no b-frames, no trellis, vbv-bufsize 10000, vbv-maxrate 10000, cabac can be hard to decode, etc.
--tune fastdecode is also a good option.

Best thing is to try different options to find a good quality/settings ratio.
