Why does the timeline expand for no reason?

I've been having the same problem over and over where for no apparent reason the timeline grows from maybe 10 seconds to something like 200 seconds. I'll resize it back to the original time, and the next thing I know, it's expanded itself again. I can not figure out what triggers it. Although typically it seems to happen to slides that have audio ... that's not always the case. Unfortunately, this isn't specific to any one .story file. I've had this same experience in multiple files. Is there a setting that I can change that will keep the timeline true to what I set it to? I'm working in Storyline 2. Thanks for any help. This little glitch is costing me a lot of time.

Hello Marge!

The timeline normally defaults to about 5 seconds. When you insert audio or video it will adjust to the length of the inserted media. However, inserting a new slide after that should revert to the default.

Please confirm that you are working locally as described here. Also you could follow the steps here if you continue to have issues.

You could also attach your .story file here to see if we can recreate the same behavior.

Thanks ... but I am working locally already. I do understand that the timeline would expand to fit any video or audio. This isn't that. This is just an unexplained increase in the timeline way beyond the length of any slide elements, including video or audio.

Unfortunately, I can't attach my .story file because it is proprietary content. However, as I mentioned, this behavior is not specific to one .story file. I've had this happen before in other files ... both Storyline 1 and 2. It seems to be worse in v. 2 though.

ok .. thanks. This is not something that happens when I first create a new slide. I am working in the slide ... the timeline is whatever the default length is ... I add a couple of things ... it's still fine ... and then somewhere along the line, the length of the timeline just out of the blue changes. I'm realizing now that I usually notice it when I go to preview the slide. I notice then that my seekbar is much longer than it should be ... and when I leave the preview mode, I see that the length of the timeline has changed. Also, if I run the slide from within development mode so I can add cue points to the timeline, it will take a long time to start to run ... probably because the timeline has made itself several minutes long.

So it seems to be preview and running the slide that are triggering this to happen.

This is a pretty old thread but I am facing a similar issue as Marge. With no apparent reason, the timeline increases to somewhere between 500 to 800 seconds. I have tried all that has been suggested but still the same issue keeps recurring. I am not sure what is causing that. I have to manually go to each slide and reduce the timeline to appropriate length and it is quite frustrating and time consuming. Any help woul be greatly appreciated.

Sorry that's happening, Dublu! Since this thread is older, I'd like to start fresh. Can you help me with a couple more details?

  • What version of Storyline are you using?
  • What were you doing just before the timeline jumped between 500 to 800 seconds? 

In the meantime, try this time-saving tip: Click and drag the end of the timeline to the left, and then press the left arrow key while dragging the mouse. The timeline should then jump back to the correct length.
