After you get your video on to Video Edit Magic's Timeline, you can use the "Image Transform" effect to invert the video upside down. By default, the "Image Transform" effect flips the video horizontally. You will find the "Image Transform" effect under the "Video Effects" tab of the Collections window. To use the effect, drag and drop it to the Effects Track in the timeline.

You can also rotate and resize your videos using the "Animated Transform" effect.

Animated Transform (called 2-D Transform in earlier versions) is a video effect that you will find under the Video Effects tab of the Collections window.

If all you want is inverting a video upside down then you can also use the "Image Transform" video effect present under the Video Effects tab. The "Image Transform" effect was available in older versions of Video Edit Magic.
