I know this thread is old, and bumping it may not be a good idea. But I want to avoid creating another thread just to ask another resolution question, so I'll use this one.
So... I recorded a small test video about Final Fantasy IV and uploaded to youtube as unlisted. You can see it here:
https://www.youtube.com/watch?v=uNPijeLILKI
It was said that SNES games' native resolution are usually 256x224 in size. Then I used VirtualDub and increased the video's resolution from 100% to 300% using the filter "nearest neighbor", making it 768x672, so youtube will be able to play it as 480p.
However... I noticed that the video looks strange there on this resolution. I mean, it looks normal when it's static, but when it scrolls, the scrolling looks a bit awkward. It looks like the video got compressed a bit vertically, so the lines of pixels are running into each other. Which gives this weird visual effect and makes it look odd when I move up and down.
Can I resize the video to a better resolution which will play better on youtube (without the weird visual effect) and hit 480p at the same time? If so, what resolution should I use?
