You can use Swing Tune-Up's swing compare feature to compare two swings side-by-side. We designed this tool to make the comparison easy while enabling a deep frame-by-frame analysis experience.
You can enter the swing comparison view from the swing analysis view by tapping the compare button.
You should see the original video on the left side of the compare view. Tap the + icon to open the browser to select which swing to compare. You can set filters to narrow down your search so you locate your desired swing easily.
The video playbacks are synchronized, so you can watch both videos simultaneously to learn the difference in swing tempo. If you want to control just one video, you can use the timeline bar on each side to jump to different positions, as shown above.
You can tap |< and >| to jump to the previous/next swing stage.
You can enable/disable annotation overlays by tapping the annotation button.
