HOw can I play back video stored as 30pfs back at 7x the speed? Basically I want to view the vid at 210fps. Most players can play back faster than real time, but so far I haven't been able to speed it up to 7x (in neither MPC or VLC so far).

Reprocess the video in Virtualdub to 60-90 fps and then use VLC to speed up to 2-4x. Or just use Virtualdub to reprocess it to 210fps

VLC does support 7x playback speed (well, it actually displays 6.99) using the keyboard shortcuts for Faster (Fine) and Slower (Fine). I believe the default shortcuts are [ and ] .

Of course, bog standard Windows Media Player supports 7x playback speed too; uncheck 'snap slider to common speeds' in Play Speed Settings (View -> Enhancements). Playback may well be a bit more jerkier than in VLC. WMP will try to output audio.

If your CPU/GPU can't smoothly play the @ 210fps, you could try decimating the fps by 2 or 3 in virtualdub first.

:thanks: Using the 'fine' controls worked. Odd, that the 'standard' conrols only got it up to 4x.

What do you mean, after 4x it jumps to 8x , then ~16x and ~31x .

My bad, forgot to use the keys. Fixated on the slider only. :o
