black lines on edge of mp4's imported into Storyline
Feb 06, 2024
Hello, I've searched here for possible answers to an issue I'm encountering with imported videos/mp4's in my Storyline course.
When I preview the slides, many of the videos which I've cropped or re-sized to only take up a portion of the screen have black lines usually either on the bottom or right hand side of the video or both.
I did find a discussion here where it was explained that the dimensions need to by divisible by 8, but even when I try to crop or re-size the mp4 to these dimensions divisible by 8 I'm still encountering the problem. I am creating the animations in a graphic design software called KeyShot (which I'm fairly new to), and most of these are rendered at 1920 x 1080 but when I import the video into Storyline, it automatically converts it to the size of my story screen which is 1365 x 768.
I have moments when I think I've fixed the issue, but then later I see the lines again.

Hi Meg!
Happy to help with this!
It would be easier to assist if we could have a closer look at the .story file that's been giving you trouble. Are you comfortable sharing a copy here in the discussion or privately through a support case?
In the meantime, my teammate Joe shared a troubleshooting step in a related thread you may find useful.
Looking forward to hearing from you!
Was there a solution to this? I am encountering the same issue. I ended up having to manually add lines on the other sides of the video creating a 1-pixel frame around the video. I don't want the frame, but it was the only way to make it look like the lines were supposed to be there. I also tried laying a box over the unexpected lines to cover them with the same color as the background and that did not work.
Hi Andrew!
Sorry to hear you've also run into this setback!
If you're comfortable sharing your .story file, I'd be happy to take a closer look to see what adjustments can be made. Feel free to upload it here in the discussion or privately through a support case.
We'll delete it from our system as soon as troubleshooting is complete!
