I cannot do it either as MOV (purchased QT version 6). When rendering in MOV, I wrote by hand the extension of the file. But anyhow, the best is always to ender your animation image by image as a non compressed JPG. 1. if you have a crash, you can restart it, where it has stopped 2. you van easily assemble and compress the animation then in QT. I don't know about B&W, never have tried it. Are you using Mover 4 or just Vue ? :-)Guitta
