So many media players only show the key frames when scrubbing, making it a much less pleasant experience. Some mobile phones (Apple, Samsung) built-in media players seem to do it nicely, but I've never found a desktop media player that does it (VLC can't).
Probably would require a lot of extra decoding behind the scenes to extract all the frames, but worth it on a modern machine.
Right seek 5 # In seconds; these are limited by keyframes
Left seek -5
Shift+Right seek 2 exact # Smaller non-keyframe-limited, seeks with shift
Shift+Left seek -2 exact
Anecdotally, I’d change that “sometimes” to “often”. After years of using `exact` I finally stopped. It always felt that the wait was longer than going to the previous keyframe and rewatching the bit. Now if I could only find the perfect timing to go back, though.
That said, I have replaced most of my "exact seeks" with "sub-seek"; in input.conf:
Alt+Right sub-seek 1 # Go to next/previous sub (within demuxer-readahead-secs)
Alt+d sub-seek 1
Alt+Left sub-seek -1
Alt+a sub-seek -1
demuxer-readahead-secs=120 # sub-seek only works within this cache
demuxer-hysteresis-secs=60 # Fill cache only if lower than this; saves battery
I think it's also bound by default, but I'm not sure what that is from the top of my head. You'll definitely need to set that cache as it's only 2 seconds or so by default.
