md5sum can take a while on large files, and video files are known to be large; it may be worthwhile anyways and better as an opt-in option to do this. Would it be feasible to run md5sum against just the first and last X megabytes of the clips that are incorporated into a project, to help keep this quick for very large files?

eljefe$ time md5sum mall_trip_015.dv
The above md5sum didn't take too long but with a whole lot of clips it may take much much longer; or not. Just a thought.

This 'off-line editing' would be fantastic, as it would allow for less disk-access for the main files (which may be stored in another location); the kdenlive project file could then be sent to that location for rendering. I think this would require a low-quality copy of the footage to work, however. Would it be worthwhile (for RAM reasons etc) to have a tool to convert/compress the real footage to a much smaller version to work on? Or is this overkill and not needed due to the way KDEnlive already works?
