video2sb3 is an unofficial, free, and open-source Python tool to turn videos into Scratch projects. Try it out here!
Before video2sb3, you had to convert any videos you wanted to import into a GIF, and then import that into Scratch (which was unreliable). You also had to convert it into an MP3, import that, and create the playing code yourself... But that all changes with this tool, which converts your videos directly into a Scratch 3 project file for you, including compressed images, audio, and pre-made code!
If you have any questions, feel free to make a discussion. If you enjoyed, you could also follow me on Scratch.
