I’m having the same “Kronos” crash. I’m also time-stretching footage with frame blending (Pixel Motion), from 25 to 30fps, though in my case the source is an image sequence (2k x 2k JPGs), not a compiled movie. And I’m outputting an image frame sequence.
It’ll work for a while, but AE crashes every 3000 frames or so. Fortunately, it’s an image sequence, so I just set AE to Skip Existing Frames, and start the render up again. Unfortunately, the whole project is some 60,000 frames, so at this rate, I may finish up several days from now.
I’m running a multi-machine render with two machines rendering the frame sequence. One has XP, 4G RAM, the other XP64, 8G RAM; CS3. Both machines crash eventually, at different points. I tried disabling/enabling Disk Cache, no diff.
I ran the same 25->30fps conversion project using After Effects 6.5’s old frame blending method, which worked as well as it always did. I thought I would see if CS3’s Pixel Motion version of frame blending worked better. It’s slower, for sure — and not just from the crashing.
