A few things to know :
- Bitrate is adaptive to accommodate for
- slow to high speed transport layer
- windowed to fullscreen image size (as for C++ you pay for what
you want :)
- resolution can be forced ( click the bottom right gear )
- The original format you upload matters : see

- YouTube quality can be very high :
https://www.youtube.com/playlist?list=PL5BF9E09ECEC8F88F (again,
go fullscreen with high speed connectivity or force the
resolution and possibily wait for data to come)
- As it's been stated a few times in this thread : YouTube
reencode the videos for various reasons, a particularly important
one being security. Some people use videos to do code injection
so they don't distribute a bit precise copy of the source. It
needs to be a valid video from start to finish with no hidden
data.

I'm not an expert in videos but as I mentioned I've studied a
few options last year before deciding to use archive.org as our
reference upload site.
I got curious just now, so I just uploaded two screenshots:

http://i.imgur.com/CEFCgAi.jpg with youtube.com
Indeed the archive.org resolutions looks visibly better; my
understanding is archive.org is streaming the very mp4 content
I uploaded to it. Could anyone give more detail on what
processing youtube does?
Thanks,
Andrei
