A python script that converts a video.mp4 into a text file, that can be played back as video in Scratch. This all works without costumes
Make a folder somewhere on your computer
Store the python script and your MP4 video inside of that folder
Run the script through Visual Studio Code or Command Prompt
Just type in the video name (with .mp4 at the end), wait for the conversion to finish, and you now have "colors.txt"
Download the VIDEO.sb3 file
Open the "VIDEO" list, and import the text file
You will not need to change any code. Just click the green flag
If you want to add your video's audio, just replace the sound in the SOUNDS tab
