hey, thanks for explaining the details.. i didnt know much about the editing potentials of these render formats,. but now i feel frame by frame sequences are more flexible towards the end.
And as i...

yes, i work using real time(24 fps) setting.. it is playing in the scene but the output has no voice.. is this is a common issue with avi renders?

My rendered video doesn't have sounds. It is totally muted. (maya 2009)

Sound works while i play the animation in its scene file. Its there in playblast output too. But when i render its gone....
