I'm trying to lock the exposure time to a maximum of 10s so I have the same interval for each new sub, this way I don't have to vary the frame rate for the video in the final. If the sub time increases to let's say 30s the video will accelerate for the longer subs because the sky moves 3x further 30s than 10s. I can compensate the signal by either opening the lens or modifying the ISO on the fly. Not sure how to set the camera to do this.
