After a bit of compression trial and error, I've figured out what to do to get a truly full quality video uploaded. This is a great comparison of the best in 2014 consumer video capture technology versus the same thing from 2007.
Back in 2007, the best I could do was record 480i video at 30 fps through an analog capture device, deinterlace it, and heavily compress it using the very early h.264 algorithms.
The new setup allows an all-digital, 1080p up-rezed 480p capture at 60 frames per second using 60 mbps. The video is (slightly) zoomed to fill the whole screen, making it conform to modern video aspect ratios. I also ran a color enhancer that will pull out some of the details from the game's rather dark rendering style. (The latter two changes help mitigate some of the artifacts of the way old video game consoles output analog video.)
Check it out! Be sure to select the highest quality setting available in the gear menu.
Pretty good, huh? Compare that to the original upload garbage.
The change is so drastic that I've decided to remaster all the Krystal cutscene videos from both Adventures and Assault. This is THE best quality you can get without emulating the games to run at a different resolution. I've already recorded almost all of the Adventures cutscenes. It's just a matter of cutting up the parts, compressing them, and uploading them to YouTube. As always, the full quality versions will be available for download here. That way, you can see the video's quality before YouTube recompresses it to a lower bitrate.
Finally, I am planning on doing a midnight stream of the Star Fox parts of Super Smash Bros. Wii U once I get it on November 21st. More details coming soon.
I've made an image comparison of the same frame using different capture techniques. After looking at it again, I think I'm going to go with the Remastered (widescreen) version.
