Youtube time optimization while uploading a video

Yesterday I was uploading a video to Youtube and I have a rant.

I think Youtube should ask all the video meta data after you upload the video. Or better yet: while it's being uploaded. Because I didn't want to think of a description (which I know can be edited later) and just leave the file to upload, because I had a heavy file (almost half GB) and I wanted to start uploading it while I thought of the description and meta data, but, at least in the web based uploading interface, this doesn't seem to be possible.
