I posted this over on Gaf but I figured it might be useful to some of you as well so I thought I'd post it here as well.
Youtubes compression is usually pretty rotten. Gameplay footage is always a blurry, splotchy mess. Using this method, you can use the same source footage and get the end result to look significantly better while the file sizes stay identical.
What you need to do is simply make your source footage 2x its normal size using the "Nearest neighbor" resizing method. Here is an example of the difference and below that will be instructions on doing this on your own.
Method used for creating videos
The video was originally shot at 720p - 30fps.
Both videos were exported from Adobe Premiere using the H264 codec, the High profile with the level set to 5.1 and a bitrate of 50mbps. Both videos are 359mb.
The only difference between the two videos is that for the 1440p video, prior to importing into Adobe Premiere it was opened in VirtualDub and resized to 2x using "Nearest Neighbor" resizing. As a result, basically every pixel that was 1x1 is now 2x2.
Quality comparison
Here are the videos in question for you to compare.
720p native resolution video
1440p 2x resized video
Watch both videos in the highest available quality to compare.
Below are some frame grabs of viewing the videos on Youtube in fullscreen compared to the source 720p footage.
Go here and mouse over the image to see the difference in quality between the 1440p and 720p upload.
Instructions
These instructions will cover how to make the video 2x size with VirtualDub. Afterwards you may use any video editing application that you please but I will give settings for exporting with Adobe Premiere as that is what I'm familiar with.
Resizing with VirtualDub
You should now have a video that is 2x the size of your source footage with quality being identical other than each 1x1 pixel now being 2x2.
Adobe Premiere export settings
As for why I use that bitrate, it is Youtubes recommended bitrate.
If you've got any questions send them my way and I'll try and answer em.
