Yes thats why I usually add a link to the encoded original file in my YT descriptions. Ok it is still not lossless, however x264 with a quality factor of 18 is already quite close. As the colors are concerned, most loss is due to the conversion from RGB to YUV.

VLC says the format is unsupported when I use those steps. Same result even if I modify the hell out of them in arcane ways. So if not that, can I get OS 8.6 to output at a more normal refresh rate?

on my previous post, i'd also like to see a r_mode 2 (512x384) capture just for the double-scan to make the filter clearer. 😀

I cannot seem to capture low resolution accelerated voodoo3 through the TV-out. 🙁

Sorry everything you said went over my head. It seems very specialised. Might be worth for you to get a capture card 😵

The system is all packed away again.

I still have the original 60 fps 1024 x 768 capture off a V3 3500 for GLQuake and Quake 2. Around 1 GB each.

Alright, now I'm just confused. I swapped to a different DA-15 -> DE-15 converter, and now I'm able to select a much wider range of resolutions and refresh rates. Including 640x480 @ 60Hz. And STILL VLC and Avermedia RECentral are unable to pick up the signal. What in the hell?

You could send an uncompressed file and youtube would still butcher it's quality. A youtuber I follow on social media posted a few screenshots a while back showing stills of the original and after youtube's processing, and it is absurd how the colors get messed up and how compressed anything with too much detail onscreen looks.

Didn't get a beter video on YouTube using diferent codecs and resolutions (most of the time iswas much worse) so we have to live with it for now I guess.

Don't know if its common kwowledge that RECentral can downscale recordings? Done it with this recording to get the aspect ratio correct from the DVI DOS output of the graphics card.
Ofcourse YouTube caused some strange glitches (specially in the txt scrolling) but the colors are this time much beter.

The thing is I don't know if it actually scales the image or "signals" the computer that a monitor with a certain resolution is connected. Either way the end result is as you describe.

I capture in Recentral and then produce in PowerDirector 13. Here you can adjust aspect ratio in case you have a 16:19 1920 x 1080 recording of 4:3 material. 4:3 videos I render at 1440 x 1080 and 16:9 videos at 1920 x 1080. Sometimes I render in 4K for no reason apart that it has the option so why not use it. But it doesn't do 4K AND 60 fps which is a bit of a shame.

Also the card doesn't do 1600 x 1200 or 1920 x 1200 which is annoying because then you're stuck with 1024 x 768 for old games or 5:4 ratio at 1280 x 1024 but here the Game Broadcaster does 50 fps max.

I'm still always tempted to get the DVI2PCIe but the price just scares me.

EDIT: http://www.startech.com/AV/Converters/Video/P … ponent~PEXHDCAP

Is anyone using this card?

And this one seems new: http://www.startech.com/AV/Converters/Video/u … i-vga~USB3HDCAP

I wonder who makes this product. It uses the capture software StreamCatcher:

Manual page 9: http://sgcdn.startech.com/005329/media/sets/U … l/USB3HDCAP.pdf

The manual mentions 4:3 support but not what resolutions.

http://www.sixfortyfive.com/streaming/xcapture1.html

This one seems interesting as well. But who sells it here?

There is also a new USB 3.0 product from epiphan: http://www.epiphan.com/products/dvi2usb-3-0/

A bit cheaper than the DVI2PCIe

I asked them about the DVI2USB 3.0 and they assured me it supports the same resolutions as the DVI2PCIe. There is a difference however, it doesn't support full RGB at higher refresh rates, but YUV 4:2:0 Color Space.

Not sure how important this is though.

So including shipping it would be $859.90 compared to $1199.90 for the DVI2PCIe.

I guess the USB interface makes this product a little bit more convenient / flexible. But still a LOT of money.

It would be awesome if someone would bite the bullet and test that USB 3.0 capture device from StarTech.

Was thinking the same thing but the price kept me from buying it and take the gamble (and I could get an Avermedia ExtremeCap demo model for a nice price)
Maybe someone can persuade startech to send one for a Vogons preview 😉 ... maybe for your YouTube channel? 😎 😁

That Startech USB 3.0 device would be great if it has the same mode support as the Micomsoft X-CAPTURE-1. The Micomsoft should be able to do standard VESA resolutions at 60Hz. The DVI2PCIe card is nice, but very overpriced for what it is. I believe it uses an off the shelf Analog Devices capture chip like the rest of them, but it can do oddball refresh rates without a problem.

Datapath is another PCIe option although I don't know how they handle picky sources (this card uses an Analog Devices chip for capture): http://www.datapath.co.uk/products/video-capt … e/visionrgb-e1s

They have older PCI cards with VGA input as well. There are usually a few VisionRGB-PRO on ebay for under $50. Drivers for modern versions of Windows are available for them too.

Micomsoft X-CAPTURE-1 is interesting but I'm finding it hard to find information and option to purchase.

StarTech support is pretty average I found in terms of answering technical questions or testing something for you.

Micomsoft doesn't sell outside of Japan, many folks have purchased them from retailers that ship overseas like Solaris Japan. The shmups forum is an excellent source of information on upscalers and RGB capture devices, there is a thread on the X-CAPTURE-1 there: http://shmups.system11.org/viewtopic.php?f=6&t=46689

With all these devices, drivers are a major factor on stuff working or not. Also keep in mind that if your content switches video modes often, you are going to have problems. Video capture applications usually expect video coming in at the frame rate and resolution you set. Some of these devices will scale on the fly to match your capture resolution, but do a poor job of it (it get worse when the frame rate changes, hello jutter!). An ideal device would stop capture and start a new file at the new target resolution/framerate. The only problem with that method would be frame loss from the card re-syncing with the source and starting the capture again.

That is not the whole truth. Ideally the device delivers frames as they are shown by the VGA card. The video stream represents these frames in time and resolution. Actually there are container formats that support resolution changes and frame rate changes on the fly. So it is all there, however software support is poor. You have already problems to find a software that supports resolution changes on the fly. (VLC does)
I couldn't find one yet that supports variable fps within the same stream.

This Mac capture thing is kicking my ass. Have any of y'all captured footage from an old Mac successfully?

I contacted StarTech and they couldn't help me. All they could tell me is that it supports 720/1080 p/i. A sample unit was also denied.

I left some feedback after receiving a feedback survey link but I doubt anything will come out of it.

It really comes down to someone on VOGONS purchasing and fully testing this unit. The contact on YouTube who used this product didn't respond to my questions either.

Lol, you actualy did it, awesome but didn't you notice the smileys in my reply 😁
Got this as reply from startech :
This capture device will also accept standard definitions, from 640x480 up to the max resolution supported (1080p)

Coming back to the USB3HDCAP.

I believe it's on sale now with Aamazon.

I know that some European countries have no questions asked return policies when shopping online.

Is anyone able and willing to help out, purchase this unit, do a through test of VGA and DVI resolutions (640x480, 800x600, 1024x768, 1280x1024, maybe 1600x1200, 1920x1080) + DOS support (BIOS screen, boot process, 320 x 200 VGA games) and when done ship it back?

My brother could do it but he doesn't know enough about Computers and the specific things we are interested in 🙁

http://www.startech.com/AV/Converters/Video/u … i-vga~USB3HDCAP

We have a return policy but its more complicated.
Yes we can return within 14 days but the package has to be unopened and undamaged so testing isn't possible, also almost no shop here has one at stock so trying to ask for a review give little hope of success.
Did some further research, none of the capture devices that is using the CY3014 driver seems to be able to capture dos resolutions and/or 70Hz.
At least there are no reports they can... The xcapture-1 also needs the xsync-1 even to be able to capture older 15 and 24 KHz signals if google translate is correct.
Looking for a "cheap" solution seems to be going for a cheap vga to hdmi converter that claims it can hande 720x400@70Hz and hope the best of it i guess 😢

That's frustrating that there are no decent reviews and the manufacturer is not helpful either.

Yea I use that StarTech Scaler and it works well. The only issue is that it outputs in reduced RGB (15-235) colours. So you either have to convert it which adds more work or just live with colours being a bit off. Again nothing in the specifications tells you about this. I guess they just assumed it would be for connecting to a TV and not a PC.

Spotted this device: avertv.avermedia.com/Upload/ProductImag ... asheet.pdf
