Why You Fail to Play or Upload SB3 Files?

Q: "I have a SB3 file for YouTube upload but it won't let me process it through? It says the file type isn't supported. There are no instructions on how to convert a .SB3 file. Scratch saves it as a .sb3 file, I can't make it a MP4 or anything like that. Please help!"

A: An SB3 file is not a real video file, it's just an on-going project file created using Scratch 3.0, a block-based programming language that allows users to create interactive stories, games, and animations, containing all the assets, scripts, and sounds used in your Scratch project. In other words, the SB3 file is an exclusive file type and can only be opened using the Scratch 3.0 editor.

HD Video Converter Factory Pro offers a dead-easy way to record SB3 projects to MP4/AVI/MOV/MKV with high quality. With this tool, you can even edit and convert your recording with ease. Get this SB3 to MP4 recorder tool and have a try!

Is It Possible to Convert SB3 to MP4?

The short answer is NO! SB3 is the only export file format used by Scratch 3.0, and there is no direct way to render the SB3 file and export it to an MP4 video. Therefore, any application that claims to convert SB3 files to MP4 is a lie, let alone those SB3 to MP4 converters online.

Quite a few years ago, someone found it could be done in a roundabout way. That is, convert SB3 file to SB2 using a Python-based program => port Scratch 2.0 projects to SWF files using a SB2 to SWF converter => then convert SWF to MP4. However, the cumbersome workaround has been obsolete and the tools mentioned don’t work anymore.

Now, the only workable solution is, record your screen with audio when you run the SB3 file in Scratch and save it as an MP4 video. Next, we'll take you through the step-by-step process of recording and converting SB3 to MP4 using a handy video processor.
