A message from Castmagic April 2025

Hey Sumolings 👋

We wanted to drop in with a quick update directly from the Castmagic team.

First up—YouTube Imports.

If you’ve had issues importing YouTube links recently, you're not imagining things. YouTube updated their Terms of Service and has been actively cracking down on third-party downloads. Even major platforms like Descript have deprecated YouTube importing entirely due to these changes. We’re actively exploring compliant solutions, but this one’s a tough nut to crack—so thanks for bearing with us. In the meantime, the best solution would be to use an external downloader and then import directly into Castmagic for all your content creation needs.

Next—Studio is our top priority.

We've heard the reports of export instability in Studio, and we’ve already rolled out several fixes to improve performance. But we’re not stopping there. Our current 6-week sprint is fully dedicated to Studio: adding powerful new features and customization options, boosting overall stability, and rolling out an upgraded UI/UX to make it even easier to create stunning visuals, audiograms, and captioned clips.

We’re super grateful for all the feedback—it directly informs what we build and how we prioritize. Your support means a lot, and we’re excited about what’s coming next.

Thanks for being part of the journey.

—The Castmagic Founders
