(It will also be much larger, but still smaller than the video on the right since h.264 is still going to be a better codec even in intra only mode)

No idea what Quicktime is doing here, but I’d be impressed if it worked on typical HD content. Still, I don’t get what the point is necessarily. Even if h264 scrubbing could be “fixed,” it’s always going to be horridly inefficient. There’s better encodings for that...

The problem isn't long videos, it's *short* videos. mpv by default uses non-exact seeks which are most efficient and will round your seek position to the nearest keyframe. But if your video is 8 seconds long like OP, you can only seek to one or two places. Try it with mpv.

With long videos, you can't tell that your scrubbing is only landing on seconds that are a multiple of 3. When your video is short, you can. This applies to mpv default settings too. You *can* ask mpv to do exact seeks, but then it'll eat CPU and run slowly for hi res videos.

Hmm, you seem to be right. Consider me fooled, I thought it looked more granular than that at first.
