Video timeline tie to seek bar

Aug 05, 2022

Hi all, 

I understand the video timeline doesn't tie to the storyline seek bar. Now I run into problem in this scenario:

We have a long 30minute video where we want to lock the video timeline in 3 sections. After the first 10 min that watched portion is unlock and the rest of 20min is still lock. Same happen at 20min (first 20min unlock and last 10min is lock). In middle of the video there is an inactive button to jump backward or forward to different part of the video. And at the end of the video it will trigger a "Complete" button where user can click and exit back to the menu. 

I can't program the seek bar so the other way is to put a transparent block on the video timeline. But of course once the first portion is unlock and user can scrub the timeline and off sync with the seek bar and the "Complete" button won't come up at correct timing. 

Another way is program a scroll bar that control the video. But that comes with hundred of commends and become very complex. 

The easiest of course is to break the video in 3 different piece but need to have a single timeline.

Any other idea please?

Your issue is not really if the video timeline can be tied to the slide timeline; that's easy. The real issue is trying to lock and unlock the video by thirds.

If all you want is a video timeline tied to the slide (Storyline) timeline, do this:

take the seekbar off the video and start the video when the slide starts. That puts both the video and slide on the same timeline, which can be controlled by a seekbar on the slide.

Although it occurs to me that if you use only a video seekbar, you might be able to place three invisible shapes over the corresponding parts of it. If those shapes are filled with color, and made 99% transparent, it might work. When the seekbar is moved, moving over the shape might break the connection between the cursor and the seekbar, preventing moving it into a locked third.

Edit - A second thought makes me realize that while that would prevent moving ahead, it might prevent moving back. I'll have to test it.
