(Sorry, I'm not good at English, so I used Google Translate.)
I was speedrunning my 8-4 iL with the fceux emulator and luckily I got decent results.
The resolution of the window I was playing was 768672, but it was recorded in 1280720 due to the wrong recording settings. As a result, the video was stretched horizontally.
Can I get on the rankings if I upload this video? Do I need to change the resolution of the video? Or do I have to make a new video?
If you need to change the resolution of the video, please tell me how. Even if I search the internet, it is difficult to get the answer I want, so I ask here.

It can still be accepted, don't worry

Videos that are low resolution or stretched are still accepted as long as you can still see what’s going on. A lot of runs in the very old days had mediocre quality since not all of us had high resolution. So don’t worry

As long as the video is at least somewhat watchable, it is fine
