after razoring new clip boundary goes gray/distorted

[Callum]

I make a video file into clips using the razor tool. Taking two such clips and playing them sequentially causes the image to distort and become gray right after the boundary for a few moments before normalizing. This happens in all profiles I have tested and when a razored out clip follows an image or another video clip. It does not happen if I just place a whole video file after an image in a track, and play through the border. The gray/distortion carries over into exported video.

Solved by not using MTS files as input. Converting to MP4 with ffmpeg fixed it.
