Matching slide timeline length to video length in SL2

Note: I have submitted a feature request on this issue, and hopefully this won't be a problem in the future, but in the meantime, I suppose this is a decent enough workaround (although it is somewhat cumbersome). Also, if you have a better workaround, PLEASE let me know.


Unfortunately, SL has some limitations when it comes to the player timeline.

Key among those limitations is the problem of matching a timeline to the length of media. This becomes an issue when building a sample slide for repeated use. If I create a video slide, and then later copy the slide for use with a different video, the timeline remains at the length for the original media. Sometimes the difference is several hundred seconds. There is no way to select an option for "snap timeline to media length". (Also, weirdly enough, the timeline is only listed in number of seconds, not minutes: seconds: milliseconds.)

Here is my workaround until the "snap timeline to media length" feature is added:

1. Replace old media with new

2. Right click media and select "Edit media..."

3. Write down the trim length of new video (here, the times are shown in minutes:seconds:milliseconds) E.g. o5:49:22

4. Grab calculator (I'm a concepts guy, not even slightly proficient at math). Calculate (e.g. 5 x 60 + 49.22 = 349.22 )

5. Close media editor

6. Right click media and un-check "show always"

7. Set cue point at media length+ (e.g. 350)

8. Drag end of media from end of timeline to cue point. (takes forever)

9. Drag timeline to cue point (faster, as I can press the left arrow while dragging)

10. Save and preview

If you have a sample slide you use for repeated use, I know a lot of people save that in an unused scene without the video. Duplicate it, then add the video, and avoid the problem.

Even if you have to replace a video, when you add a new video, and before you do anything else, right click it and deselect show until end, sometimes it shrinks its timeline to the correct length. Delete the old video, and jump directly from step 1 to step 9.

2018 now, the problem still exists. Maybe people don't think of it as a problem. But my experience said otherwise. I wasn't aware of this weird design and ended up having multiple videos with stretched length. The SME told me, "there is a bug in your video" and I went back to change all of them. Huge waste of time!

So my conclusion is:

There should be a feature that adjusts the timeline to the longest video on slide; and this should be default.

But before that happens (maybe in 10 years), my workaround:

What I did is to use a short video (start with the shortest video) as template. If you duplicate that slide, then any video longer than it will expand to the right length of the video. No extra work is needed! JUST REMEMBER to start with the shortest video.
