There is a bug when dragging the tennis ball to mark the ball landing in the service box, it doesnt move right or left. This happens about every other time. Also it is annoying that the video reverts back to the begining position after marking the contact point, it should be easy to make the video resume at the point after i mark the contact point, so i can mark the ball landing point. Most of my videos are of multiple serves so it is really annoying to fast forward and find the serve in a long file.
