Among all the Magix typical problems, this seems hopeless: as in video attached, when in Proxy the video can be seen, when not in proxy, the image disappear, just a few pixels can be seen. Of course that at export, those pixels are all there is... No video. The ,mov is ok, works on everything but Magix, the PC is performant, the same video works not long ago well... It's like a course, this program...
Please help!!!
