Ratings and reviews

Works as expected. Love it

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.

I am really curious what is the frame rate of the video it gets the time from, would be nice if it could get it faster like 50 fps or something because for example I can t get exactly the frame when the ball bounces, one frame before it didn t make contact yet and one after already it bounced a little . Maybe you could use also the audio to find the frames ?

What's new

Support for Reverse motion added. Now if you miss an important frame, you can always go back to it.
Some important UI optimizations too.
