I use shotcut, which is open source. It’s a little rough around the edges. I used to use adobe premier (cracked) but adobe figured out how to get around it, plus it kept crashing.
I wonder what people use, since I’ve heard a lot of people for shorts/tiktok just use those web editors instead of making their own thing.
I use Kdenlive but it gets a hint crashy time to time. Especially if you put multiple large files in the project, woops.
