Questions
No. It is turned in this tab with your browser, so the file never leaves your computer.
Yes. The turn is baked into the picture instead of saved as a note in the file, which some players ignore.
Every frame is re-encoded as H.264, so there is a small loss, as with any re-encode.
Phones record in one direction and save which way they were held. Some apps and editors ignore that, so the video shows sideways.
Many webcams show you mirrored, so text behind you reads backwards. Flipping left to right fixes it.
Current Chrome, Edge and Safari, which can encode H.264 video.
