If you optimise a video for original quality, for example, the resulting file is often smaller, of great quality still and requires no transcoding unless for network reasons. In this circumstance, it’s better to simply replace the original file with the optimised version. Currently, I have been doing this manually and it’s a pain in the ass
There’s already a feature suggestion for an option to keep only the optimized version of a video.
