Changing gears a bit... What's a good, cheap way to capture "high-res" 4:3/5:4 modes at 60 or 75Hz? Specifically 1600x1200 or 1280x1024.

I guess any modern game capture device should have the horsepower to do this, but do they allow those resolutions or force you to "1080p"?

Modern game capture devices are geared towards 16:9 resolutions, typically 720p, 1080p and few high-ends supporting 4k. Neither 4:3 nor 5:4 are common enough anymore to be supported. Less so any going above 60Hz. Lastly most are only going to have HDMI input, and while you haven't specified type of video signal I assume it's most likely to be analog. In short your requirements definetely fall out of what modern game capture devices support. To summarize this very long and exhaustive thread you basically have two routes: a VGA-HDMI converter/scaler paired with a generic HDMI capture card, or not-so-cheap pro capture cards from vendors like DataPath and Epiphan.

Hi!

I am looking for advice. I need record video from C64, C128, Amiga 500 and DOS-based VGA (up to 800*600).
Will be good have posibility record and see video at one time.
PC-dvr is mac mini (with usb2) or laptop (ubuntu, usb3) or old PC with Amd Phenom (4 core).

CPU: Amd K6/450, RAM: 256M, VIDEO: S3Trio V+, SOUND: EWS64XXL/64M
CPU: iP/100, RAM: 16M, VIDEO: S3Trio V+, SOUND: SB AWE32
IBM Aptiva, CPU i486DX/80, RAM: 96M
Compaq Contura 4/25 2820D, CPU: i486SX/25, RAM: 4M, VGA.
HP 200LX/2M

So, as result, i'll try AVERMEDIA C039 EZMaker 7 - for my Commodors and AverMedia LGP Lite GL310 for Dos VGA

Thanks, for help!

Hi, so if I buy the following: "Datapath DGC103C Vision RGB-PRO1" I will be fine for VGA/DVI with convertor capturing ? Thanks

DGC103C is PCI card with VGA input. E1/E1S is PCI express card with DVI-I input. Which one to use depends on your capture PC specs and combinations of target resolutions and refresh rates. DGC103C is much older model and PCI bus doesn't have bandwidth to allow for capturing high resolutions and refresh rates.

I have a separate capture card Elgate Game Capture HD which I can use to capture from DVI source (DVI>HDMI cable). I have PCI & PCI-Express slot.
The purpose would be for capturing from VGA source (WIN95/DOS); would the older card DGC103C be the best option then ?

In that case yeah, it'll cover analog VGA capture for you as long as you don't push resolutions and refresh rate too high for it to handle. Dual-head variant sometimes can be found at same price as single.

Be aware there are models with PCI-X interface and some sellers mistakenly label them as plain PCI or even PCI express, so be sure to check which model you're buying and photos are real.

After I read arncht posts on pouet with

we could enjoy the original quality, if it would be possible to capture and show 1:1 (generally not possible 320x200 is not 4:3 - scaling needed, especially with mixed resolutions), and capture with the original frequency (would be possible with some limitations) - practically you need an analog crt display.

I still think that is doable.

For the 4:3 aspect it is only required to have a container format that is able to specify the output aspect ratio, like matroska (mkv). Then the player scales any resolution of the video stream to a 4:3 aspect.
Now for resolution and frame rate changes the video stream has to support that and there are formats that can actually do that. If you employ f.e. mpeg_ts live streaming in vlc it automatically adjusts.

The actual problem is that most of the capture or streaming programs are designed such way that the end user sets a resolution and frame rate, whereas the wanted feature would be that the video source defines the resolution and frame rate (frame time) on a per frame basis.
It wouldn't even be a problem of the output then with GSync/Freesync screens.

I am sceptical, that you dont have any problem with the video players. Another problem is the youtube.

is there any card, where is possible program and drive not just the active modes, but also possible to add special modes? i mean, eg set the 400 line vga and the text modes separately.
the datapath e1s would be very nice, but the api is limited from this aspect.

It is the same mode, thus a capture card can not distinguish if it is text or graphics showing.

No, not the same, it is possible to detect and program it. The position is also different (if the card cannot detect the difference), just it does not matter on a crt with black borders. But this is just an example, i also would like to set different modes.
