    Having built something similar with CLIP on an M1, frame sampling rate is the whole ballgame. One frame a second on 12k videos is days, keyframes only got me to an overnight run.

      Have you tried scene detection? I would guess camera cuts are even less frequent than keyframes.

      Maybe you need a minimal downscale version as well, I heard is very common technique in the video editing world.

      Based on my experience, sampling rate can be tricky if what you are looking for lasted less than interval period.

        Proxies. You transcode proxies from the original media, edit off those, then you use OM for the final render. NLE’s usually let you flip between them.

          And in this case, you'd still end up with the same number of frames to process, right? They'd just be smaller frames with less fidelity.

            Yes they are generally a fraction of the bitrate. As low as 1/4th or 1/5th typically IME. But it varies.

      > 12k videos ?

      you are pirating first-release movies for commercial purposes?

        I think 12K is quantity not resolution.

          Such a tool is very helpful for editors who manage video footage, and since 12K cameras are affordable now, I'd guess 12K actually refers to the resolution here.
