I mean the video still does not look as good as vimeo in html5 but the main pixelation and blocking is not there.

I have made another discovery, If I view the videos using youtube HTML5 ( https://www.youtube.com/html5 ) they look fine!

I am going to try and talk to someone youtube/google about this as it seems very odd that the default adobe flash player encoding causes such quality degradation.

It appears that it was a youtube problem all along as the video looks fine on vimeo.

My theory is that youtube has started to give SD video a lower bit-rate, hence 1280×720 video looking much better as it allows for a higher bit rate.

I came across this thread on youtube of people experiencing similar problems https://www.google.co.uk/support/forum/p/youtube/thread?tid=3261e6e60e29f228&hl=en

But when I render the footage out to a .MP4 and view it on my computer it looks crisp and fine, it is just when I upload it to youtube the video becomes blocky (I have uploaded footage before taken in daylight that also had the same problem).

Thanks I really appreciate your help, Here is the some raw footage for testing 1406_hvarc3.avi.zip

It is not the exact same one as the file size is too large for my slow internet but it is from the same shoot and the subject.

@Aleksey Tarasov Do you mean sharing the original .AVI clip (very large) or the rendered .MP4 clip on a file sharing site? (The rendered .MP4 clip looks fine on my computer in VLC media player).

Thanks.

Before I upload it, the video files rendered out in Vegas look fine when played in VLC media player and windows media player. it is just when uploaded to YouTube they look blocky and loose lots of quality.

I have tried many bit rates from the 3mbps you recommended all the way upto 15mbps yet they still look the same.

I am going to test NTSC 873×480 now to see what results I get.

Edit: still no luck, same blocky effect

@Aleksey Tarasov I tried that but the quality was still poor and blocky.

@John Rofrano Still no luck when trying your directions. How ever if I render using 1280×720 it looks much better when viewed in 720P on youtube, but still poor in lower resolutions and with an internet connection like mine 720P takes an age to buffer.

, how ever there are videos taken with the same camera by other people that look fine in 360P and 480P like this one

I am out of ideas as into why my footage comes out looking poor when there are people using less advanced means to edit their footage yet it comes out looking fine.

Thanks for the reply, but after trying those settings it still looks blocky and washed out

Do you know what is usually the cause for these “blocks” appearing in video?

@Aleksey Tarasov thanks but I am not comfortable inputting my youtube login details into something I have not heard of.
