l'd recommend AviDemux as a video converting/editing alternative. It's completely free, has a lot of conversion options (lots of file types/encoding, quality settings ++), allows for simple editing (mostly trimming down video, removing scenes, also crop, flip, resize, rotate etc, and more stuff but i don't rly use complicated stuff). It allows exporting frames, but tbh mostly I just trim to import mp4 to photoshop. But since it's free (not trial) it doesn't block any features! And v lightweight.
Also since when importing mp4, you just edit out the specific scenes, you can go really high quality file so you don't really lose any quality to compression.
Ah, thanks for the suggestion! I just ran some tests, and the output quality is indeed much better than any mp4 converter Iâve used so far (and Iâve tried a fair few lmao). đ
