[QUOTE="Povl H. Pedersen, post: 21908, member: 4634"] Not sure what the jitter is, it could be from EIS (Electronic Image Stabilization) if that is part of the stabilization process. Do you have a frame grab where you can analyze it closer ? But we also have image resizing taking place Video is not a 1:1 crop, but likely closer to a scaling to less than half size (3968x2976 original). Have not looked at cropping to see how much it is actually scaled. For action cams, I try to pick nice scaling factors. 1920x1080 is likely a 2x2 sample to each movie sample. Using 3840x2160. That leaves 816 pixels vertical for EIS / 128 horizontal compensating for the missing yaw gimbal axis. Aka 2 degrees sideways. EIS is not dependent on the IMX377, but on the image processing chip.
