Why does Rise file size increase when using SMALLER VIDEOS?

Thanks Hazel! I came to find out that the main reason my file was so large in the first place, was because I had simulations in there as blocks, and when I was searching the zip package and sorting by file size, to identify the largest pieces, I did not realize that the sims are in another folder, therefore not displaying when I was trying to figure out why it was so big. I had not looked at this course for a while, and forgot about the sims. All is well now. Good to know about the videos too.  That explains why the file kept growing in size, when I was reducing video size, thinking that was my issue!
