If it did, what it says, it would be better

This program can, oh, sooo much! But if you want to actually use and allowed to try to put an effect to a clip, the display is out of sync and jerky. On the same computer Adobe Premiere has no problem with that. The effects are not working. And if so, it is apparently not intended that removing an effect. But there's no button. It is the exact opposite of intuitive. You really have to read about each process the PDF. And then you will not find often, what one seeks. Too Bad. I would not buy me. Certainly not.
