a film from YouTube

[czgirb]

The software used is:
* Firefox with it's Video Download Helper add-ons
* Media Info

For example:
whenever there is a film, which i love, on youtube ... at first, i will download it in Medium (360p) version.
After saw it, and I decide to collect it ... so I download it in 720p version

regarding to the resolution ... i believe it was previously set by youtube.
but regarding to the video bitrate ... is it also set by youtube or the software that i used?
is there a standard for youtube downloaded video's bitrate?
please guide me to the URL
thank you

Unless you're reencoding it, the bitrate used is YouTube's.

is there a standard for youtube downloaded video's bitrate?

Yes, and it's done by resolution. Just download videos of the various resolutions and you'll figure it out.
