I’m trying to use a video for a base to draw over and I can find where the place to upload the video into the app??
Yes you can! just import the video on Candlestick, our most advanced and best fork https://candlestickers.app/ just, click on open and open any video you want.

then create 2 layers, one with the video, and one with the animation.
the candlestickers is a blocked app on my school laptop is there other was to add videos to the app. n
If you want to add video frames to Wick without using Candlestick (and not having a script/bookmark to help), you would need to add each frame individually.
or just adding a gif, or uhh yeah your method
Note, transparent GIFS are broken in normal Wick Editor.
