The photos below are from the same time in a video that I made but played with 2 different apps. The one on the bottom with the pink bars across the screen was from software I was using to add music to the video and it happened again later in the video. I've used the software to add music to another video that I made right before this in the same location that doesn't have the bar. Any ideas about what happened?
It looks to me as if the application you were using, or indeed the tablet, is not able to properly handle 4K material. Perhaps try editing on a computer instead.
Appears to me to be a copy of a screen capture (second generation maybe) with digital lag. Seems only one frame affected, which is odd too. You should put the original P4 captured video on YouTube so we can a better look.
Thanks for the replies. These are screen shots from the video - the top one is from the video player playing the original video and the bottom one is from the video editing software. The video plays fine in the video player on my tablet and the bar isn't in the original video. This only appears when editing the video to add music. I have another video that I made right before this video in the same area with mostly the same shot and the edited video is fine.
