Yes. You can use Video Edit Magic to flip your media files horizontally or vertically (mirror).

The Image Transform Effect can be added to the effect track corresponding to the video track that you wish to flip. Once the effect is added to the timeline, you can resize or move it to an appropriate position or double click it to change its settings.

In addition to flipping, the Image Transform Effect can also apply X-Ray, Invert Colors (Negative) and Grayscale to your videos. You can also use this effect to change the opacity of your videos.
