Video lag when slide appears
I've been using video in courses for awhile and haven't come across this issue yet.
Setting up a few variations to how a learner plays multiple video:
1. Four small videos on one slide. Each with the controls attached and each set with trigger to stop when the timeline starts. Users click each video to play.
2. Four thumbnails of the videos with an overlay play button. Off to the side is a larger shell to play each video. Then each video resides on its own layer. Respective triggers in place to manage this setup.
3. One main video centered on the screen.
The current format is .mov
Outside of Storyline they play fine and as intended. Yet, in any of the configurations above when you click to play, you hear audio for about 1-2 seconds and then the video catches up now out of sync. Audio ends and then you see the remaining video play.
I thought at first the lag was due to having multiple videos on one slide, but it shouldn't behave that way in option #3 with a single video on one slide.
Any thoughts? Is it perhaps the .mov format? My next move is to convert to mp4 and flv to see if there's any difference.
