Attempting to export video from my google pics or someewhere to YouTube

I think this is a little video of students art of a winter scene we worked with. I'm testing why I could not export the vid I wanted. Seems it was not exporting because the file is too big at 2 gb. I had the option to download it but google drive warned that it was too big for them to scan for viruses, this vid seems to be exporting. We'll see. I'll have to break up the other one, or something.
