Just sharing the settings I have it set at incase you wanted to skip the guess work.
I use OBS but I'm sure it will be a similar setup for other programs.

After Import media > Right click on video/layer and select "Filters". Then Add + "Color Key" filter. Change "Key Color Type" to "Custom Color". Next, click "Select color" and type in #74461d. Please reference the screen shot above for the additional settings that will need to be adjusted for best results. Also enable "Loop/Repeat" option for the video.

I made static versions as well. You can click on them to download.
