Thanks falconperigot Looks as if only quicktime is support for sound. If thats the case not that impressed. I can get round it by adding the sound after rendering & using my video editing program to add the sound. Was hoping to do it all in carrara. Ive created a talking figure in poser 6 using mimic for lip sync.I then import into carrara for further work. Also found that transposer does not import the sound file. I have to add it after. Was hoping that I could save time by doing all the final animation work in carrrara 5 pro.
