This assignment was definitely a challenge but I did enjoy doing it. I really wanted to keep my character a certain shape, close to the sketch of my character. I had trouble getting the walk cycle to move the way I imagined it. To help I actually took a video of myself walking, Doing the keyframes first and then adding in-betweens was very helpful.
Same thing happened to me. When you are uploading a new post on a laptop/computer, there will be a little side tab on the right of the screen. Add your GIF then scroll down on the side tab. Under “Image Size” there is a drop down tab, select “Full Size” and it should play you GIF properly 🙂
