I think it would be “interesting” if you could compress already compressed images/videos. They are typically not candidates for advanced storage features.
You cannot really, since the Shannon Entropy of such files is pretty much maxed out already.

But let's say you have a large no of smaller video files, sitting in an ONTAP (WAFL) based system. This 4K block factor, the new "Compaction" will give a positive effect.
Again: it depends
