What instead of Playmemories on Mac?
I would be most grateful for recommendation on what alternative to use for Playmemories using the not compatible macOS Big Sur to edit videos from my Sony RX10M4 camera.
The PlayMemories app I can locate was for Sony PlayStation, not sure what you were using.
For editing video on Mac, iMovie is free, and Final Cut Pro is not.
There are a couple of Adobe Premier packages, Pro and Elements.
I’ve mostly used iMovie.
