In disguise, if you want to replace a range of frames in a piece of content, you can render only those frames that have changed, and tag them with a frame index.
The file that you are replacing frames with needs to have its own version number, so if the original video is "myfile_V2", then the n in the format:
‘myﬁle_v3_frameXXX.mov’ where XXX is the first frame number to be replaced. Note that frame 0 is the first possible frame in the clip, not 1.
the file ‘myﬁle_v3_frame187.mov’ replaces frame 187 onwards in ‘myﬁle_v2.mov
Please note: If you want to replace a set of frames in clip version V, the new clip should have a higher version number (V+1), not the same number.
