Re: is image sequence faster than movie?

Until somebody else (like Todd) answers, I'll have to do: leave them as sequences. Generally, getting frames from disk, whether stills or movies, is not the biggest part of a multi-layer render. The biggest part is the number of calculations required to render each frame of the final piece. It's the same for a RAM preview.

But ... if you have time to spare, don't take my word for it. Do a render test with the Render Details visible. After it's done, add the time it took to make the QT movie, then compare.
(Make sure the QT movie is neither MPEG nor HDV.)
