Clear the sequencer memory cache? I'm doing some motion tracking, and to quickly edit things I preload the frames into the memory. However, this fills up my ram, and sometimes (e.g when I'm not working with the footage) I want to clear it out of memory. Can this be done?
If you reload the clip on the Movie Clip Editor, the cache will be cleared.



Also keep in mind that the amount of memory used for the cache can be managed on the System Preferences (CtrlAltU) ->System ->Sequencer/Clip Editor ->Memory Cache Limit
