I'm using obs with a canon XA50. I'm shooting at 50fps 1/100 F3.7. If I pan the camera back and fourth the view in the camera seems normal but when I do the same and look at the view in OBS it looks like the whole picture is swaying. The top part of the video seems to move slowed than the bottom part and there isn't a line like when you should use v-synv. Any idea of what could be causing this issue?
