I usually record and edit videos from Sega Genesis and Super Nintendo games via emulation but I never had to do 3D games before. Not every game on the PS1/Saturn/Nintendo 64 games are 3D but 3D is different from 2D and even 2D sprites are better animated than the SNES or Genesis. I am mostly using emulation to dump the videos and it already has an FFMPEG resizer built in but I want to know if I should a Lanzcos resize via Virtualdub2 or some other method to make it presentable?
Edit: To add to my question, what should do about the settings of the recording when I am editing the videos? I usually like to make videos of individual levels / Should I use the same settings as the video below? Or different settings?

That bitrate looks rather low for a capture master. Use a high a bitrate as you can stand if you're going to use x264, crf 12 or less, crf 0 (lossless) if you can. At least you used 4:4:4 chroma. I would avoid resizing while capturing. It's best to avoid multiple resizings.
Can you post a sample? -
As I suspected that video has lots of compression and resizing artifacts. If you can, avoid resizing and use better quality compression. A better source would give smoother edges and an overall cleaner picture.

Since you're already using x264 -- set it to crf=0 -- that will give you lossless encoding. And disable the resize filters -- capture the emulator frame pixel-for-pixel.

Hi Guernsey
All current emulators have a video capture engine (I use Retroarch for 95% my captures).
As Jagabo said, use the X264. My configuration is above:

For resize you have 2 options:
1 - Use some editor like Virtualdub + Avisynth filters
2 - Use upscale from emulator Retroarch using shaders like xbr, xbrz (recommended) or nnedi3 and already record in upscaled mode.

I see. So are certain settings in x264 encoders such as DAR (Display Aspect Ratio) similar to SAR (Sample Aspect Ratio)? Or they different from each other? Other than that there isn't that much difference between most of those encoders right?
-
I just noticed that Guernsey's x264vfw dialog shows DAR instead of SAR (the version I have has SAR there). DAR and SAR are different settings. DAR is the display aspect ratio, the final shape of the picture. SAR is the sampling aspect ratio, technically the relative distance between samples horizontally and vertically -- people think of this as the shape of individual pixels. I'm pretty sure x264 doesn't support DAR directly. So the program that Guernsey is using must convert DAR to a SAR for x264:
Code:DAR = FAR * SAR DAR = display aspect ratio, the final shape of the picture FAR = frame aspect ratio, frame width:height SAR = sample aspect ratio, the relative distance between samples horizontally and verticcally

Okay I think I should be good. I will give those a shot.
-
What do you suggest I use as far AVISynth + Virtualdub filters?
-
nnedi3_rpow2(), aWarpSharp2(), Sharpen(), LSFMod(). For cartoons you may want to use line darkeners like Hysteria() or FastLineDarkenMod(). You also want to reduce noise and other crap before upscaling -- otherwise you just get bigger crap. RemoveDirt(), RemoveGrain(), TemporalDegrain(), etc.
