Camtasia looks like a nice way to make medical teaching videos, but there appears to be a show-stopper problem. I can't find a way to loop the short medical video clips to match another timeline, like the audio. For example, medical cardiac images are typically 1-cardiac cycle in length (e.g.: 1-sec at a HR of 60 beats per minute). The medical clip needs to loop over and over again without jerk or pause in between until an audio description of the loop completes (say 2 min). Simply duplicating the loop won't work for a variety of reasons and would be very inefficient (would require 120 duplications for the example given). Is there a setting to loop continuously?
