Importing 4:3 size file to 16:9 size file : how to make it easier and work fine? -Storyline

Jul 26, 2016


I guess it never hurts asking this question. I am working on one project with the size of 16:9, then now I have to import some existing slides from another storyline file made by the size of 4:3 which was designed by others. As we can imagine, after importing the 4:3 file to the existing 16:9 file, every slide from 4:3 file looks kinda messy and just fits in the middle of the slide, I have to manually adjust them slide by slide. So, is this the only way to do that?

On top of that, some slides from the 4:3 file were generated by video screenshots, I don't think I can adjust the screenshots to fit the 16:9 size screens?!

So, any thoughts or suggestions?

Thank you so much

  • You could import and scale to fit, to 16:9 this will be fine for most elements.
  • Then manually replace the elements that can't be stretched and should be manually scaled.
  • Full screen Images, or screenshots that require resizing to 16:9 may benefit from scaling in something like photoshop.e.g. 4:3 image, scale up, use a sharpen filter, crop to 16:9, this way it fits without being stretched. this would probably be the fastest way.
  • alternatively some screenshots may work well in a nice frame, such as a photo of an ipad or a computer screen, you use the scale difference to your benefit. e.g.


Hope this helps

Hi Phoebe,

Never hurts to ask the question! I'd agree with Byron's recommendations, and you may also want to look at how you set the story size elements before you import the slides.  You could use some of those features to have changes take effect automatically in a new file, and then import that version into your existing 16:9 set up. 

Screen recording that have been inserted as a video on a single slide should be available to scale as a normal video, but any screen recording inserted as a step by step on multiple slides become a part of the background and therefore cannot be scaled.

Hi Byron,

I simply imported 4:3 slides to 16:9 template and manually scaled some messy slides, but like Ashley said, I can not be able to scale those screen recording inserted as a step by step slides since they were a part of the background, but fortunately it did NOT look that bad. LoL

Thank you once again. :-)

Good to hear it worked for you, I think there may be another option

In the original project those step by step slides could be set from step to to step, to videos and then you should be able to scale them :)

In that case you would loose the step by step,elements such as captions

the other option would be to set the resolution of the original project higher but with the same aspect ratio, set to publish with scaling, publish and capture it with a new story line project open in the desired ratio

hope this helps

Thank you very much Byron once again for two alternatives. :-)

But, I thought another question based on the first alternative in case in the future I will run into the same situation: How to reset the original slides (4:3) from step to step, to videos mode? The thing is the "step to step" mode was identified/selected before saving. Can we still change this mode to "videos" mode (in one slide) even after we saved it already? I think we cannot change the screens mode after it is done/selected. Sorry, I am kinda confused.

Thank you.

Hi Phoebe,

When a screen recording has been inserted into your project, the original recording still exists as well and you can insert it again in as many different ways as you like! Click on the arrow icon within the "Record screen" button and you'll see all the screencasts available - just choose one of those and you'll go through the insert process again!

I am having a similar issue. Screencasts were taken in Storyline in a file with a 4:3 story size. I want to move the screencasts to a 16:9 file and then create a step-by-step test mode simulation. If I make changes to the screencast such as stretching it to fit, I see that when I use the drop-down to then convert to step-by-step test mode, I am back to using the original screencast and any changes size changes I made don't apply. Should I try changing the story size to 16:9 in the 4:3 story (where the screencasts were recorded), first, before importing to the new 16:9 file?  I

am not sure if this would only apply the size changes to the recording on the slide--not the saved original that can be accessed in the dropdown to create the step-by-step layout. Also, is there a way to change the name of the saved screen cast. I changed the name in the slide, but in the drop down, each of the screenshots are named by date and time of recording, and it is hard to tell which is which.

Hi Deirdre!

I'm happy to help!

Yes, you can change the Story size to 16:9 and then add the screen recording again. In this video, I resized the story size while the screen recording was on the slide and then I added the screen recording to a new slide with the 16:9 story size. 

It would be easiest to import the screen recording to a new slide with the exact ratio you want!
