Importing large number of frames form Video - improved method?

I find that import times of individual frames behave very different depending on what frames I want to import: Table[{x, AbsoluteTiming[Import[vidName, {"Frames", x}]][[1]]}, {x, 1, 30000, 1000}] … Thanks, mondo EDIT: ran my suggested single-frame import/crop/export loop and found some interesting pattern in the timing for each import: Does this immediately make sense for anyone? …
