This is a simple workflow I use to upscale videos and increase FPS.

Choose between 3 Upscale methods: RTX Video Super Resolution, Upscale by Model or Upscale Image By lancos, etc.

Interpolation can be disabled and Target FPS set as needed.

If you want instruction for any of the nodes I use, please look to the creator's documentation.

Feel free to message me and ask questions and I will do my best to help you when I am able.
