Re: Slowdown in rendering animations 2004-01-26 - By joe_ashear

Andrew,
I don't know the answer for sure, but I have a theory. If nobody
chimes in with a definitive answer, at least you have this. :-)
I think it has something to do with rendering directly to a finished
movie format like QuickTime or AVI. I assume you're using QuickTime,
since you say you're using a Mac. I think that as the file gets
larger, it takes longer and longer to append a new frame to it. So you
might have better results if you render to individual files and THEN
save the finished movie.
I just tried rendering a series of files in "Sequenced TIFF" format.
When the rendering is done, you see a completed movie in Carrara, and
you can save that movie in QuickTime format. I used a very simple
file, so I couldn't tell whether there was any speedup. But you may
see a difference.
