Need help uploading avi (unity errors)

So I have an avi I’ve been trying to upload for a few days but I keep getting errors when I do and I don’t know what they mean (I don’t have a lot of experience with unity), I’ve figured out how to fix some of them, but I’m still stuck with these. I have no idea what to do now and I really need some help or someone to look at the avi themselves, pls
