I have Adobe Premiere Elements 12. I’m running it on Windows 7, Intel 2.5Ghz, 6GB RAM. The input video is shot on a Sony DSLR, AVCHD/MPEG, 25 fps, 1920x1080.
I am trying to video myself drawing and then speed it up. However there is a significant loss of quality after I’ve done a vertical flip, horizontal flip and sped up the video. The video appears grainy and jittery. I’ve tried a number of combinations. When I make no changes to the video then the output is fine. The main loss of quality seems to come when I do the horizontal and vertical flip.
Any tips on how to reduce the loss of quality or where to read to learn about this would be greatly appreciated.
