Does what it says...
...but it doesnt bother to maintain any metadata about the original file. If we drag in a video clip from iphoto, even if we select to save the file in the same place, the new file that is created as ouput of this program loses geographical location, date of creation, etc. This causes iphoto to treat it as a brand new file, and it is difficult to reset all these properties by hand (if even possible for the average user).
I would give 5 stars if the program would literally do as one would expect and simply rotate a videos orientation without having to muck around with creating and organizing new files and restoring metadata by hand.
