One of the Youtube members and I are using the same capture card in addition to the fact that we both use component leads. But we both get different colour graphics and smoothness. Mine is a little sharper and has more saturation. I tried to adjust the setting, but it does not give exactly the same as his one. This is my video https://www.youtube.com/watch?v=XM8vJAux3IM and here is the other one https://www.youtube.com/watch?v=81BW2tYuo6c. Can anyone tell me if there's other factors that affect recording?

Analog always varies from device to device and cap to cap. You upscaled/uploaded 1080p, the other guy uploaded 480p. Youtube always allocates more bitrate to HD video. That's why your video is sharper.

Even when I upload it as the same resolution, mine still has different colour graphics. Is it something has to do with rendering or pc graphic card? -
You're looking at only one component in the processing chain. Same source, same cables? Same processing, deinterlacing, capture codec? There's much more than the capture card to be considered. And even then, don't expect an exact degree of sameness even if the two entire setups are similar.

The proc amps on capture devices exist because analog video capture is always imprecise. No two devices produce the same output. Even a single device will produce different output depending on age, temperature, cables, etc. No two capture devices will produce the exact same results even if their settings are the same and the sources are identical.

I have just found the guy I was referring to uses Virtualdub for cropping, resizing, and deinterlacing video. I use that too. In Virtualdub, there are plenty of colour depth settings. I have no idea on what these are. Can somebody tell me what colour setting should I choose and which one gives me closest result to his video? My video is darker and more saturated and his is slightly brighter and deeper colour graphics.

What a shame. Makes me shudder to think of the results. Most would suggest Avisynth.
Color depth is unrelated to saturation or brightness adjustments. The YouTube encodes discussed here were encoded at a color depth of YV12. There is a table of the color depths that Avisynth can handle in the wiki page at http://avisynth.nl/index.php/Convert. Virtualdub can handle most of them and a few others . If you want to know about colour depth and colorspaces, try this video which has several good links for greater detail: Introduction to Color Space.
No one can advise about color settings because we have no idea what your video looks like.

Generally, you want to avoid unnecessary colorspace conversions. Colorspace conversions may lead to loss of accuracy and blurring of colors. Your source is probably interlaced rec.709 YV12. But many VirtualDub filters work only in RGB so you may not be able to avoid converting to RGB. In VirtualDub's Filter dialog enable Show Image Formats to see what colorspace each filter is working in.
VirtualDub doesn't handle interlaced YV12 properly. It will irreversibly screw up the chroma when it converts to RGB (it blends the colors of the two fields together). You can sometimes avoid this by requesting the source filter output YUY2 or RGB instead of YV12. It depends on whether the source filter can provide that or not. If your source filter can't output YUY2 or RGB you should use a different source filter.
Your sample HD images may show a difference caused by incorrect rec.601 vs. rec.709 color decoding.

VirtualDub generally uses a rec.601 matrix to convert between YUV and RGB. The greens in your sample images don't look different enough to be the wrong matrix.
If you upload an RGB format video to youtube they will convert it to YV12 with a rec.709 matrix before encoding.Last edited by jagabo; 8th Sep 2018 at 10:40.

The graphics card and driver can effect what you see on-screen. But it doesn't effect the actual captured video file.

Hello all. I know it's an old post, but I'm still working on getting the colour display I want. I know video display I've posted above have different texture. Would chroma change help me get the same display?
-
Changing the chroma doesn't change texture, it changes the colors. The first picture has more saturated colors than the second. So you can increase the saturation of the second to match the first.
-
I'm trying to match the second one. I found FixChromaBleeding filter does reduce saturation level and colour correct video. Would that work?
-
I suggest you fix the problem where it starts. Adjust the video proc amp in your capture software to get the colors right to start with.
