What's the best way to record a video on Mac without the camera flipping right and left?
QuickTime doesn't seem to have this option. I tried QCamera as it was posted as the answer to a similar question How do I prevent the mirror-effect in video recordings in Photo Booth?
but it doesn't have an option for recording video, only displaying video.
The only way I have access to the camera where the video is not flipped is FaceTime, but I have no way to record it (unless I did a screen capture on top of FaceTime, which just seems unnecessary).
Best Answer
Shift+Command+H will flip a video horizontally in QuickTime after you stop recording.
In summary:
I tested this on macOS Catalina using QuickTime 10.5.
