StoryLine 3 and Camtasia Studio 22 Codec Jul 18, 2022 By Colin Davis Storyline 3 Update 17. I've just updated to Camtasia Version 22 and when I try to import an MP4 video it produces, Storyline says "Could not be imported ... latest media player ... and codecs". The video plays fine with MS Media Player and VLC Player, but won't import into Storyline. Storyline can import a different video created using PowerPoint. Camtasia Studio and Storyline are both installed on the same PC so the codecs are there. Any ideas?
