I know this is off topic but I'm looking for a reference so that I can help people with submitting reports. Some bug reports are lacking file samples as the problem files can be rather large.
I'm looking for the best OS X command to clip a movie file to create a smaller of a file. I found:
dd if=sample-file of=small-sample-file bs=1024 count=5000
Is there a better way for users to create a clip to submit with their bug report?
