In this case converting a movie from one video format to another can take an hour, running such a conversion on all my movies and youtube videos would probably take both CPU cores of my server for several days. I really don't want to do it needlessly.
i figure you know this but for other readers, i'll point out that another way to cater for this without using a Makefile is to move the original file somewhere else after it has been processed. e.g. i've used a ./originals/ or similarly-named subdirectory and mv the original file into it after processing. also makes it easy to delete them all later. alternatively, you can check to see if the target file already exists before doing the conversion (you'd have to manually delete the targets if you wanted to re-run the conversion with different options) craig -- craig sanders <cas@taz.net.au>
