Expression to delete every 13th frame

[Dan Ebberts]

This time remapping expression should work:

f = timeToFrames();
n = Math.floor(f/12);
framesToTime(n+f);

Hi Dan. Please tell me, I have a video where there are freezes, frames are duplicated. For example, frame 25,26,27 is the same frame. Is it possible to somehow evaluate the contents of the frames through expressions and delete all duplicates except frame 25 ?

I don’t think there’s any practical way to do that with expressions. You’d have to use sampleImage(), and I think it would take forever to analyze enough pixels to determine two frames were the same.
