Sammie Roto 2 Fork

Sammie Roto 2 on GitHub

I forked Sammie-roto-2 and pushed some code to make all of it work on OSX. Recently I also added LTX2.5 Gen Alpha as an matting option to it.

And of course some more goodies like EXR image format and tileable renders with low VRAM:

  • Added a configurable memory budget with tiled VideoMaMa processing on MPS and CUDA
  • Optional automatic matting export.
  • Refactored matting, segmentation, and object removal into self-contained engines. * Switched image loading and processing to OpenImageIO and NumPy, adding EXR and other supported image formats, multilayer EXR export
  • Updated shortcuts: F to fit, H for 100% zoom, and Left/Right arrows to change frames.

This probably will be a separated fork and won't go back to the original repo, because I completely refactored the code so every engine (SAM2, Matanyone, VideoMaMa, etc) is a self contained module that can be easily removed or added in the future.
