Works great with a high FPS source video

This video player works great with a source file that is already recorded with a high frame-rate. I use videos recorded with my Sony HDR-AS1000v Action Cam at 120 and 240 FPS, and the slow motion playback is very smooth. If youre just using the built in camera or some other normal source video source file with 30 frames per second or less, the playback wont be very smooth.
