From bitmap image to vector.

I am trying to prepare some SVG files from bit maps, but the tool I an using super vectoriser converts drawn lines in the image to filled beziers i.e. it treats lines as filled shapes. What is the best way of going from a bit map to vector for animation in Synfig?

Thanks

hi good day, I post this video Video Tuto: How to vectorize a drawing on Synfig Studio about how to vectorize on synfig maybe can help

Thanks. I don’t understand Spanish but can pick up things just from the video. I will keep plugging away. Might come back with a few questions though
