Pro-tip. Don't use Upload Studio to trim your clips. On the clip itself, go to "other options" on the left of the UI, and select "Trim". It won't butcher the framerate, doesn't open a separate app, and you can then upload the clip to Onedrive or XBL in seconds.

Yeahhh...US really does mess it up...a good amount of times I get this grainy pixelated mess that I know damn well isn't 1080, or even 720. Back when I was recording every single thing that ever happened, I didn't have time to go through the whole list each time I selected a clip, but now the normal Trimmer might be a better idea. Thanks!
