a bit of good rendering news...

OK, we all know that After Effects has the edge in a lot of rendering comparisons with combustion, but today I found one where combustion kicks AE in the fanny. Revision FX Twixtor 4.5...I set up two identical compositions in AE and combustion, and with the same footage settings, same clip, same Twixtor settings, combustion took 3 minutes, 33 seconds, and After Effects took 5 minutes. A small victory, but I'll take it. Any other examples where combustion is more efficient?

Well, no disagreement there. But I was referring to rendering...if you're doing a certain process to footage, it helps to know the better option for render time.

This has probably more to do with Twixtor than combustion or AE. It's forgone conclusion that if you're going to do anything big enough in combustion, you're gonna have to farm it. Granted, this should be the case with any comper, but you get the idea. :-)

Actually, it probably has nothing to do with Twixtor being different between the two apps. It's the same plugin, with the same code. We run the AE plugin version within combustion. Okay, I'm stretching things a little, but not very much.
What is probably different is the caching mechanisms of AE and combustion. Within Twixtor we ask for several frames of a sequence at completely different times than for the frame time being calculated. I'm guessing that combustion is keeping the frames we need in memory longer than AE and, as a result, Twixtor speeds up tremendously.
This may or may not be due to *inherent* differences in the two apps' caching mechanisms. It could be, but it may not be. For example, you may setup the memory/caching preferences for each of AE anc combustion in such a way that's favorable to combustion. However, it may also be that combustion is just simply better when it comes to what Twixtor needs.
In any event, I'm glad you are seeing speedups that are favorable to your workflow, no matter what the deep-down reasoning is for the difference.
