compressed vs uncompressed feasibility question? I have multiple videos uncompressed. I uploaded them a while ago to vimeo. I lost the original files. However, I found the original files stored in vimeo under the download button below the 1080p version. I realized that the 1080p WAS 100MB in size, whereas the 1080p original was 1.96GB.

In term of storage saving the 100mb IS IDEAL, however will i lose quality? I still cannot grasp the differences btw these two version. if possible would someone explain the differences? 
thank you!
As you can imagine, a file that is compressed from 1.96gb to 100mb has lost a lot of information. The question is what you need to do with this film now. If you want to make a version to be shown in cinemas, that's not going to work well since you probably will see compression artifacts etc on a big screen. If you need to create a Sd DVD from it, probably that's fine.
