I've been a lifelong Sony Vegas user, but seems like they don't make a version compatible with Windows 10.

Are there any decent video editing programs out there that you've had success with? Doesn't need to be a super advanced program, just enough to trim and stitch a few clips together for youtube.

It works on win 10.
Use Adobe Premiere instead.

final cut pro or avid are also good
