When the source files are ProRes 422 HQ or ProRes 422, the output fails. If I transcode the source clips to MP4 prior to processing, then they successfully complete. The failed outputs (MP4 ) sometimes are playable, but only contain the first couple seconds of the video. All preview functions work as normal.
