Animated video in Content library with green screen

Jun 02, 2023

I found several animated characters in the Content Media library 360 videos and they have a green screen.  I am looking for a transparency tool under Options so I can add the animated character to my choice of background.  I can't find it.  Is it not the case?   I have looked through the forums without success. How do I use the animated video?  I will upload a screen shot.

to remove the green background you need e.g. Adobe After Effects -> "Chroma Keying"


  • there is no way to integrate videos with transparence in storyline
  • storyline uses mp4 for videos
  • mp4 can't do transparency

these videos in the content media library are just videos with a green background - they are supposed to show a green screen scene

Thank you very much. It is unfortunate that the background selected is green if SL has no transparency tool. Green screen is kind of an industry standard, I think. I have Premiere Pro and I believe I have used a green screen tool. But it is good to know about available online tools like OBS studio. I have used Davinci Resolve with success as well. Thank you both, Math Notermans and Jürgen Schoenemeyer.

Hi Doris. Just an FYI, but there are a couple of options for incorporating video with transparent backgrounds in SL.

For a super short animated character clip, you can try an animated GIF. GIFs tend to be large however, for what they contain, and have some behavioral problems in SL.

For a more robust solution, you can use a WEBM (chrome, ff, edge, etc.) or HEVC (Safari browser only) format embedded into a web object.  Once you key out the greenscreen in whatever software, render it into the desired format. You can do transparent WEBM in Premiere Pro with an optional plugin. You can overlay the WO onto other objects or images to get your final look.
