Hi, I'm attempting to mask with the Bezier plugin. When I apply to a video event however, the preview window goes black except for the mask resize cursor tool thing. When I playback, the video flashes red and black. When I track a point for the mask, then playback, it doesn't follow the tracked video, even though the keyframes are accurate.

Thanks in advance for your help. I'm about to rip my hair out over this.
