Correcting color stripes in AE
by Chase Carnahan 1 day ago
Hey all, I'm having some serious trouble with some footage I shot a week ago. (This seems to happen on most of my footage in bright settings, too). Canon 7D Canon 10-22mm 3.5 1920x1080p 29.97fps squar

I believe chromatic aberration would not be exhibited in that way. What you have looks more like moire artifacts from compression, i.e., I don't think a new lens would help. -Jeff

The only downside I've found with PNGs in AE is that they are a bit slower to read & write than TIFFs (not sure about TGAs; haven't tested yet). A small issue if you are using file sequences. The upsi

Re: 25fms to 24fms conversion
by Jeff Brown 1 month ago
A common way to do 24 <-- 25 FPS conversion is to just reinterpret the footage as the frame rate you want. I.e., tell AE that your footage is 24FPS. Then: use audio software to make the soundtrack
