App to delete unwanted media so that FCPX projects and events can be archived.
You can choose to delete: render files, proxy files, high quality media files and optical flow files. All of which can be generated if needed later. Only folders of more then 100MB will be checked for deleting by default.
You just don't want to archive to much data. So this app will help you clean up your Disc, SparseImage, Movie folder or SAN location. You can toggle all on/off, by using the header for each type of files.
An example: A film shot with a Panasonic AG-f100 camera, makes AVCHD folder of 8,7 GB. On importing to FCPX you get a new 8.7 GB just on the import. This is you extracted original recording. But were are still in H.264 land of codecs. You want to use a more power friendly codec, and you do a transcode to ProRes for editing/online. Now you have a transcoded folder of 60 GB!
