There is no way past the 10000 frame limit, and I would hate to see how particleIllusion responds when working at such a high frame number.
The only reason you’d ever need to use a particleIllusion project that is that long is if you have emitters going the entire time, with no breaks at all. Even then there is a workaround.
First, the smartest thing to do is break the extrememly long video into smaller parts… let’s say 5000 frames each (I’d probably use a smaller number like 2000). Use points in the video where there will be breaks in the emitters. Then work on each section as its own project.
Use your video editing software to put the pieces back together.
