Youtube degrades my HD video quality?

Hello guys, I recently uploaded a video on youtube and the video looks terrible to me even in 720p.
Take a look at this:
This is the video quality when uploaded to youtube.

& This is the video quality when viewed in windows (not uploaded to youtube)

You can clearly see that when uploaded to youtube the quality drops and looks pixely.
I render the video with sony vegas pro 12 and record with bandicam.
This is my render setting for videos:

& My recording settings for Bandicam:

Can anyone help out with this? How do I make it so the quality stays the same (as seen in the second screenshot) when uploaded to youtube?

It looks ok, but there's no official documentation (that I can find from a quick search) about what that quality setting is. I can only assume it's a percentage.

I don't think I've ever seen this sort of quality loss except when uploading videos that are odd resolutions. You might just have to play around a bit with some of the settings. I can't see anything specifically that would be causing issues. You could also try recording in lossless or high quality lossy and then transcode the video using something else afterwards. I normally transcode with x264 using VidCoder as the graphical front end, although unless you stick mostly to presets you'll probably find yourself confused by all the available options.

Firstly, if your original source isn't much good you can't expect miracles, because each successive transcode will only ever reduce quality (even if imperceptibly). Just because you specify a 14Mbps bitrate (which is incredibly high for Youtube anyway) doesn't mean you're going to get an improvement if your source is garbage.

Secondly, Youtube will always transcode your videos, so give it the best you can to get the best final result. That doesn't necessarily mean the highest bitrate either. I'm obviously not privy to exactly what transcoding goes on when you upload a video, but I would not be surprised if the service has decided that your 14Mbps video needs to be cut right down to be even close to a bitrate that can be streamed on most connections, especially for a relatively low resolution. Most 1080p videos I've watched don't average over 8Mbps, let alone 720p. Upload a 1080p video if possible, because a 720p version will be generated anyway, and the 1080p video will retain more of the original quality.

I would use a variable bitrate with 2 pass encode as kenrivers said. Constant bitrate makes little to no sense in almost all cases. Also, change your profile to High. By selecting Baseline you're telling the encoder not to use some of the more effective compression techniques, which means that it has to reduce quality further to fit inside your bitrate requirements.

Hello Sharkzie,

I assume that your footage, even after rendering it, looks better than what it does on YouTube now. Is that correct?

See, I think the problem is with your file type. Try using H.264 through QuickTime, I've found that H.264 works the best when it comes to gameplay videos.

I've watched the gameplay you uploaded and it looks much better than the majority of MV vids uploaded.

It looks even worse with the Variable bit rate and Two-pass.
You can clearly tell that the video (which is in MP4 file type) looks clear and in good quality (which is 1280x720) while when I upload that video to youtube it turns pixely and looks terrible, you can not even read the text on the pipe because of how much quality it loses.
EDIT: Are these good settings for bandicam so my videos won't lose quality?
