Hi guys, I know this is a topic that seems to be brought a lot but i could not find any clear answer in the archives list. ... After some reading in the list , i kinda figure out we cannot do CBR video (as in real constant rate ... but tell me if i am wrong !! (specifically on a Mpeg2video/mp2audio file), so what i am trying to do is @ least having a maxrate set up : meaning as our videos will be use on a satellite broadcast and as we pay for only a 2.5Mb/s link rate, i wanna make sure the video won t be choppy not being @ the proper rate. It looks like maxrate, minrate are the options i should use.. One thing i cannot figure out is the bufsize ? Anyone can explain we what it is and what the proper value should be ? (cause i have either "buffer underflow" message when set too low or another one saying "VBR will be used" when set too high !!) I would appreciate any help Thanks and cheers seb
