By far the best tool that helps you find the ball in your video and lets you pin where your ball is at in each frame. Very intuitive UI and detects your ball to its best knowledge. If the ball isn’t found you can still place a pin at each frame or just go to the last frame place a pin at where it lands, and it will generate a predicted line. It will take some effort. It took me around 10-15 minutes to trace 1 video, but it will give you a solid accurate trace.Features needed1. [Urgent] Project ball pins needs to be edit-able, currently the app will just finalize the line then generate the video, then if you want to make some edits later to some pins, you have to start over from scratch, leaving 10-30 fixes throw away work because of 1 undesired frame misplaced the bin. This will cause the tracer to be janky.2. [Urgent] Before pins go into an uneditable state, there needs to be a warning saying this is the point of no return. I wanted to go back to a few frames and edit a few pins to make the tracer less janky, but pressed next before realizing I can’t go back to edit any more.2. [Medium] Tracer smoother, the tracer comes out janky because the video is shaky. But since I placed the pins of each frame very accurately, the tracer shakes with the video. The video shake can be smoothed by our brain, but the tracer being shaky is very obvious.Overall, I’ll subscribe to support, I didn’t want to give it 5 stars because there’s still room for improvements. Will change it to 5 when at least Feature#1 or #2 is delivered. It does deserve better than the current 4.3 rating.
