Like I said before: editing and using right good codecs for converting. You can edit video clarity, color temperature, shadows etc in video editing software.
If you upload ur original file then youtube converts it to downsize your video.
If my original video is like 2gb then edited video is maybe 500-700mb.
My DSLR camera raw photos are 32mb and after editing they are 12mb.
So edit your videos, just 1 hour driving videos are boring anyway and way too long for today standards. Nobody got time to watch that long videos
Even i dont want to watch my own videos for hours, i keep the good parts only.
"You tubes settings are so that when you upload a large bandwith file it is automatically compressed loosing a lot of clarity. This is mainly because You Tube would like to keep it's bandwidth usage down so that the most people can upload and watch videos. "
