We’ve received reports that when recording video with the webcam or document camera, the footage is mirrored. This makes recording math or writing especially challenging.
The first step is to see if the program you record with has the ability to record it correctly from the start. If not, you can use Movie Maker to fix this, but it will take a few steps.
An easier option we’ve found is a tool called Free Video Flip and Rotate. This is a small program that is named very appropriately. You simply drag in a video, click one button to flip it, and save the result. If can flip and rotate in seven different directions to accommodate pretty much any scenario. When it finishes, you have a second copy of the video alongside the original.
It can save in the MP4 format that YouTube and other sites prefer. You can then open it in Movie Maker or another editor if you want to do further work on it.
