I have been posting on Dtube for ages and love it. They have always been good to me as far as quick and easy upload and smooth playback. There is a great group of folks over there like @tibfox that are very supportive and building a good community. I post there every day and I love it!

I use Vegas but got it for 25 bucks thru Humble Bundle but I checked just now and it is not available.

I looked at the open source Openshot. It looks good. I never tried it but I like using open source.
