How to remove the background in a gif?

Question

Adobe Photoshop

Good afternoon.
I just started learning about Photoshop. I removed the background in the gif in each frame with the help of a magic brush, but when you save it, this is what happens:

Tell me how to properly remove a non-monotone background so that the gif looks normal.
Here is the original gif:

Answer 1

You have all the previous frames in the timeline. And they need to be turned off. Turn off all unnecessary layers in each frame in the frame -by-frame
animation panel When switching frame-by-frame in the animation panel, layers will turn on those layers that are active. You need to turn off everything below, so that there is only one layer in each frame

Answer 2

Well, if there is a Photoshop project left, then try other export options. Either directly into the video, or into a jpg sequence and then assemble it again. But initially it would probably be easier to remove it in the video editor through keying, because in this case there is a homogeneous background.
