Hello, recently been having problems saving sound on clips, in other words I cannot press "use audio from layer" option. Even for clips using 300 frames. The clips have been either AVI, DV-AVI or WM - any ideas?. Also will Particle Illusion in the future support other video files such as MPEG-2 etc?
There are some restrictions for using "use audio from layer" -- have you checked the docs? From what I remember, input has to be AVI, output has to be AVI, and the output movie has to be the same resolution and length as the input movie.
Your best bet may be to just add the audio back in with your video editing application.
