Hi;

I have tested MainConcept AVC/AAC format for my .mp4 files. While i can watch the
files on my local pc using QuickTime-pro, others report that they only see a black
screen, and can only listen to the audio-channel.

Hence i suspect, MainConcept is not a Standard-mp4 codec and i only can see it on my pc, because i have installed sony-vegas here. What shall i then do in order
to deliver a "more standard" mp4 file ?

and how can i generate a very good quality/low size .mov file with the H264 Codec ?

thanks for any response,
regards, hussayn
