Don’t use for video comparison

Can’t use this for coaching purposes. The app doesn’t let you start 2 videos at different spots. It’s impossible to sync up 2 videos to see differences in a golf swing for example. Gave 1 star because I had to pay $ just to immediately figure this app was useless for my needs.

Response from developer

Hey Mike! Version 1.2.0 adds exactly what you are asking for! Trim each video so both swings start at the same moment, then compare them in sync with frame-by-frame stepping and slow motion down to 0.25x. Please give it another try, email support@gintechsystems.com if anything could work better for coaching once you get a chance to try the 1.2.0 update. If you feel the app is better, after testing 1.2.0, I would appreciate an updated review.
