#and the tutorials i saw on tumblr used the frame by frame method

How do you make the transparent vg gifs?

I used this website! Load your gif, set the background color to the color you want to remove and then play with the percentage until you get the shade you want gone (if the bg is one shade of green, then 1% will do the trick, if it's multiple shades of green, you'll need to go higher). Also turn off and on the Alpha Channel Preview to make sure you're not deleting any pixels of the character

BIG warning tho, I used this on gifs that had a very simple background, with one specific shade of violet and another specific shade of yellow, so I was able to colorpick the code of both and then set the percentage at 1% to only target those colors (I had to do this with one color, then save the gif, then load it again and finally delete the remaining bg color)

If you are working with something more complex, it will be more difficult, and you'll probably need to do some color adjustments in Photoshop to make the background colors different to the character's (for ex, if you want to delete the background of a gif with Mario in it, you'll need to make sure the bg doesn't contain red, orange or blue)

Otherwise you can remove the background with Adobe After Effects or do it in Photoshop frame by frame, but obvs that takes more time. Couldn't find anything more efficient than these methods sadly :(
