Seriously it is true!!

scratch has no support for movies. just images.

They said you could import .mov files in the scratch wiki.

found it, but you missed a step

Mac

Open your movie in iMovie and export it as an Image Sequence using Share > Export with Quicktime.
You may change the frame rate using the Options button. A lower frame rate is recommended for longer videos.
Open the frames with Gimp using the ‘Open as layers’ function and export as a .gif file. Use shift+click to select multiple files.
To add sounds, go back to iMovie, and export the sounds as mp3 using Share > Export with Quicktime and choosing mp3 as the export format.

scratch will not accept the .mov on it's own you need to convert it into a gif

Yeah i found that you need a program to do it
Even worse the variation was photoshop and it said you needed quicktime
