I don't know why but it doesn't remove right frames for me

ExactDedup removes only EXACT duplicates [hence the name], if a single channel of a single pixel is different, then it is not an exact dupe.
Those very precise time codes would require double precision floating point, not do-able from script.

Suggest simple dupe detector based on Ydifference threshold to create frames list and then use RejectRanges().
