The problem is the instant replay button, and the many mistakes. I have six of them posted on Corel's Forum, to be told only that cavort only users and not Corel employees on this forum. Contact? None. This is a mass product, either it can be as it is to use, or you are out of luck.
For example, I can not do it with this product to create an h.264 encoded video file (MP4) with a resolution self-selected. There are only a few pre-defined resolutions offered me. "Same resolution as the first video clip" creates an AVI, "same as project resolution" an MPEG.
Sure, I can then make an open source tool like FFMPEG darüberlaufen, but just creating video files could be provided by this tool but really expect.
And that's just the beginning - the surface is inconsistent, the size of a video I can only prune at%, but not at the pixel level - when I edit X6 videos with Corel VideoStudio Pro, I am fighting against the program. One might think that the product is mittlerweise mature, but that's not the case. Perhaps with X7 or X10, who knows. Amazon also has "CyberLink PowerDirector 12 Ultra", which has slightly better reviews. If in doubt, you should definitely try for both of these products, the trial version.
