Hey there,
I have multiple folders with multiple files from my iPhone with the original footage (HEVC, Dolby Vision, 4K60). The thumbnail generation works sometimes - then it is pretty quick. But when it is not working, it is really annoying. I have tried the multiple process option - but it is mostly the same.
Example of how I see the problem:
I open a folder with multiple pages of files. The first page is working, I got to the next page. I see: “Loading or generating thumbnails” - this stays there for minutes (or probably longer) until I close the app and try the same folder after the app restart. Then it works, I go to the next page, maybe that works, maybe not, but mostly a page later it “crashes” with the “Loading or generating thumbnails” message for a long time. I then close the app and start from the beginning. Almost an infite loop with multiple pages of files (I have folders with >100 videos).
Can this be improved? Because it is really annoying and pretty much unusable this way.
