When running the script from inside its downloaded directory the frames and processed directories are created outside the enclosing directory and the individual frames are saved inside the directory. When the frames have been extracted a path error occurs as the frames are not found in the correct location.

Rembg works correctly.

Hey,

I've followed the steps mentioned here to remove the background from the video, and it is working all right.

But when I use the -a option, to apply the alpha-matting and refine the results, it shows this warning and never generates the output:

PERFORMANCE WARNING:
Thresholded incomplete Cholesky decomposition failed due to insufficient positive-definiteness of matrix A with parameters:
    discard_threshold = 1.000000e-04
    shift = 0.000000e+00
Try decreasing discard_threshold or start with a larger shift

Any idea how we can make it work properly using -a option?
