Do I need to set-up a CRON job for Video Processing? (SIMGallery and JomSocial integration)

It keeps saying Video Processing (but thumbnail and video show when clicked). It sees like the video has already been processed, but there is still a message that says, "This video is currently processing." I worry that maybe I need to set up a CRON job or something (like other Video plugins).

Do I need to set up a CRON job with SIMGallery? It seems to work well without it.
