"idxs" is missing frames that videoTensor still had when using "--is_folder"

I have 49 video frames, and if I check the length of videoTensor, it matches (49).

However, idxs ends up being only 46 long, resulting in the first and last frame not being interpolated.

Update:

This also happens when using a video input, so --is_folder doesn't seem to be relevant here.

tarun005 commented 3 years ago

Yes, that is expected. FLAVR requires at least 4 input frame for reliable interpolation, so the boundary frames cannot be interpolated.

Inserting fake entries into the beginning and end of the input file array works fine as a workaround.
