Here’s a simple gif tutorial, using PotPlayer instead of KMPlayer. Sorry if everything is choppy in the video. I probably had way too many things open while I was recording this. Also, please ignore the part where I’m clearly having an issue selecting all the layers. The screen recording box was in the way. All you have to do is select the top layer, scroll down and hold down shift while you select the bottom layer.
Also, when resizing your image, you do not have to resize it to 502 and then crop it to 500 later. I just prefer to do that because in the past I have had issues with lines appearing around my gifs when I would post them and they are not pretty. It does not always happen and it is not necessary to go through this process.
If you have any questions, please feel free to send me an ask!
