I had teenager help. I wouldn't have been able to do it myself. But here's what I used for my videos.
Use "InShot" a free video editing app. It'll allow you to put the emoji sticker over your face. You can go thru several frames and you'll have to move the emoji a few times - size the emoji big and it'll cut down on the number of times you have to move it.
Once you have the video, create a burner gmail account to use to create a burner youtube channel. Upload your video and set it to "Private" it will open only when someone has a link to it.
Then you just need to copy and paste the link to send it to whoever you want or post here.
