Rotate video
Turn a sideways or upside-down clip the right way up, or mirror it. The rotation is written into the pixels, so it sticks in every player and app.

Questions
Why is my phone video sideways on my computer?
Phones often record in the sensor's landscape orientation and add a "rotate" flag. Players that ignore the flag show it sideways. Rotating here rewrites the pixels, so every player shows it upright.
Does rotating reduce quality?
Rotating pixels requires a re-encode. At the Balanced or High setting the difference is not visible for normal viewing.
Can I mirror a selfie video?
Yes. Choose "Mirror (horizontal flip)".
