Media Player Classic, the slow motion isn't great, but it works. and you can set the amount of jump and the keyboard shortcuts to use in milliseconds, to any amount you want.
I assign the arrow keys to short jumps, and ctrl
arrow keys to long jumps. Yes, trying to drag those bars just never lands where you want. Some limitations of jumping on some programs are because of the way things are encoded/compressed, there is one intra coded ("solid") frame, then many frames that are built out of the differences from the intra frame.
It is also usefull to know that when dragging the seek bar around in MPC, if you hold the shift key the moves are made by KeyFrame. Jumping through the file by keyframe is fast, and restart from that position begins with a KeyFrame , or solid frame, so compressed playback is instantaious without the broken frames. (may not work for all codecs)
VLC should be able to do this too. There is also Media Player Classic Home Theatre.
In VLC there are hotkey assignments available for Long jump, medium jump, short jump, and very short jump. You can assign a key to any of these. | Tools | Preferances | Hotkey |
To Alter the length of time that any of the jumps work for It is simply a matter of going to "ALL" in preferances (bottom left). In there is | Interface | Hotkey settings | , the advanced settings for the hotkey stuff. There are reports that agressive use of very short jumps can crash the player
Again not all videos will be able to jump the distance you set, if the program can only jump that video type by KeyFrame.
