How effort-intensive (or automatable) is it to take a large video file and append a picture/thumbnail to it so its not a black thumbail?

you can easily do this with ffmpeg, I did it all the time putting movie covers on movies. it won’t transcode so it’s pretty quick and you can use it in scripts or batch files. 

ffmpeg -i input.mp4 -c copy -attach cover.jpg -metadata:s:t mimetype=image/jpeg out.mp4
