Hey guys, got a quick one. I've got a comp full of image sequences that I rendered out from C4D and imported them into AE. It takes a wee while to ram preview now cos of the many layers I have. My images are PNG sequence. Just wandering if quicktime movies are faster to work with than image sequences? Is there any difference at all? Is it worth converting these PNG sequences to QT 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.)
