What is the best way to convert out a VGA signal to Composite, S-Video, Component, etc...?
I'm currently looking for a new method for capturing footage from an older desktop, over to a DVD.

Currently, I have a box that can convert the VGA signal into Composite/S-Video. I take that connection, and route it into a DVD recorder.
Obviously, at that point I have no way to actually see what's going on. So, I use the HDMI out on the recorded, and use a HDMI to DVI cable, and plug it back into the monitor.

In theory this works, but the problem I have is a noticeable delay in the image (versus an action inputted off a keyboard/mouse), and the image on the screen is incredibly blurry (DVD footage is unaffected)

Any tips on a more practical solution?

Affordable capture cards that can handle VGA are on the market.

That card is identical to the one sold by Micomsoft (makers of the XRGB line of upscalers). It has DirectShow support and works with a variety of applications.

I use this:

It has a VGA out, so you can capture and use the monitor like normal. Works very well, but only up to 640 x 480 with decent quality. Anything higher and it gets too blurry.

The two options are basically what Maur1wurf1977 linked to, or a more expensive VGA capture card.

Here is a "demo" of DOS VGA capture with my card (mainly Doom):

Remember that if you intend to capture higher resolutions the difference in quality will just increase. If you think the quality increase is worth it, is up to you 😉

The capture card goes in a modern machine. USB devices that capture VGA are practically non-existent as most only do HDMI and component. I'd say its a decent trade off for a massive increase in quality. Crystal clear nearly 1:1 video quality vs. a fuzzy, interlaced, macro block filled mess.

To be clear: the card has a VGA-in port. You insert the card into a modern PC, and then you connect it to your various other computers whose output you want to record.

Doing high resolution quality video capture with nothing but older technology is pretty difficult; I don't think it's possible to stream the data to disk fast enough without some sacrifices.

I did try a method of direct capturing to a modern computer with an external unit (USB 3.0)
It works, but due to resolution variances, especially with DOS games, it becomes a bit erratic.

Hence why I moved to the DVD option. 🤣

Looks like it's exactly what I need 😀

Any demonstrations out there on it's video quality?
Have you had any glaring issues with the unit?
