I recently prepared and delivered a Yammer broadcast to a work group. One member requested a specific segment to be used in another capacity.
I "trimmed" the original video, but ended up losing the rest of the video, and was only left with the trimmed section.
When cropping a photo or video on a phone, the cropped/trimmed media is automatically saved as a new file, and does not override or replace the original.
A feature like this would be extremely useful. OR allowing users to recover overwritten videos from the Recycle Bin.
