Video with transparent background in Storyline 360

I found that Matt's Kurtin's post is a practical solution to this issue. I understand that removing an existing background color with tools like After Effects or similar and converting video formats can be time-consuming, but the effort is worthwhile. Once you've converted your MOV file to WebM for playback in Chrome, you can encode the same MOV file to HEVC directly on your Mac to ensure compatibility with iOS devices. Follow his tutorial on integrating multiple video formats within a single video tag in Storyline. Although I don't own any Apple devices to test whether HEVC playback is successful, I've attached a brief video demonstrating how WebM transparent video functions within Storyline.
