I'm getting best results using videos of equal duration, where the cock video is slightly longer than babe video. I set the clip duration to be just under the babe video duration. I set the output size no bigger than 4MB. enable dual video groups, then cock goes in primary group and babe goes in secondary group. if the babe video has good audio, i upload the babe video to the audio group as well and toggle audio. takes like 10 seconds to generate, so im steaming through these
