Ash - what kind of shape are you inserting? Is the same shape being inserted at the same position in each frame? Please provide more details.

Could you solve your problem? I have the same issue right now. First, I read the frames and I make a video by combining the frames and after that, I need to put a dot on the video (like a fixation point).
