Clips vs Tracks
In VideoCanvas you can choose to scale, move or apply effects to either a single clip or a whole track. You choose which by clicking the Clips and Tracks tabs:
When rendering the movie frame, VideoCanvas first applies all the clip filters and transformations and then the track filters and transformations.
The clip and track tab selection also controls what you manipulate when you move things on the movie canvas. For instance, the position of an image or movie is the sum of the Track Origin and the clips Position in Track. So before positioning your media by dragging it around the canvas you need to decide wether you want to move only the current clip or the whole track of clips, and choose the corresponding tab.
