Can you adjust a slide duration without dragging the end point? May 23, 2013 By Andrew Hooper I know this has been asked before but I can't find an answer... Is it possible to adjust a slide duration without dragging the end point? I have a slide that is 900 seconds long. It contains 10 seconds of audio and 890 seconds of silence. When using a seekbar the audio ends and the seekbar is only 5% full. Every slide in my course is the same and it takes forever manually dragging the end point back to 10 seconds. I just want a box where I can type in the number of seconds for slide duration, or to right-click on the time line and select "set end point".
