My phone should already be recording at 60fps. If the video is less than that, then the issue must be in the process of transferring the video to my PC and then uploading it to Youtube. I'll try to cut out the middleman in the process of transferring the video to my PC to see if that resolves the issue.
Edit: It seems that my editing program automatically sets the framerate of videos to 25fps instead of the original 60. I will try to remember this going forward.
I've seen stuff like this being used to clip through ropes, but not through the terrain. And not 100% consistently.
At the end of the run your livesplit timer displays that your time was 41:45, but you submitted the run as 41:52, so may I ask where did these extra 7 seconds come from, or is this just a mistake?
