Trimming Videos On YouTube

This is a really quick and simple method of cutting/cropping videos that you have uploaded to YouTube (from your PS4 or any source).

Trimming/Splitting Videos On YouTube - Uploaded From Your PS4  

I prefer editing videos this way rather than faffing around with other tools such as the SHAREfactory on PS4. By doing this directly you can always quickly share whole clips from your PS4 without getting completely dragged out of the game :)
