Bug in Storyline 3 when inserting videos
Never had any issues with SL2 when inserting videos. In version 3 the video appears in a reduced format, shrinking the image. I could'nt change it, tried several options. Once the control bar was added, I could click on play but no sound, then the video continued to display while I was clicking on other layers. Then the program crashed. I tried several other actions, closing the program, etc.
My solution was to keep working in SL2 for that specific slide giving several the user several videps to watch. Then I saved this slide under a new project name. Imported that file in SL3.
I hope that you provide a patch or an upgrade soon!
