Once in awhile, a frame from a previous clip appears at the end of my timeline. I can usually select and delete it, however it gets pretty annoying after awhile. Does anyone have an idea why this happens? And better yet; how to avoid it?
If your playhead is not at the very end of a clip when you ad one, it’ll “insert” and that last frame can be left behind. Depends on what you’re doing. What happens just before this, how are you adding the clip at the end of the timeline? Hopefully not drag-and-drop but with the E shortcut.
There’s your problem, don’t use W, that’s in Insert (we call it a Wedge) edit. It splits the existing clip at the frame the playhead is on, and inserts the new clip in-between. If the playhead is on the last frame, it splits at the last frame. E is what you should be using to add a clip.
