A custom video resolution has no bearing on quality here; only the choice of encoder, bitrate/rate factor and other parameters will impact the final result. Youtube's player frame on its site is always 16:9, so if your video has an aspect ratio other than 16:9, YT will automatically add black bars as necessary. No need for the uploader to do so.

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 ...
