Video Overlay Doesn’t Work? – KineMaster (OLD) Review

Hello. I like to make Gacha Life Youtube videos and Kinemaster is very helpful. However, I screen recorded my character on a green screen and tried to use it as a video overlay on Kinemaster. It didn’t work. I was so disappointed because I have tried it before and worked. So I looked up tutorials on Youtube on how to fix it, but it seems that all the people on the tutorials had the premium version and did not have the same exact controls as mine. This is the only problem so far, but overall, this is the best editing app in my opinion.?? I would really appreciate it if you could tell me how to fix this problem on Kinemaster. Thank you for your time.....
