VGA capture alternative in Desktop

Greetings, 

I had been using Epiphan's VGA2USB adapter for my desktop units. 

being an Audio/Video enthusiast for quite some time, I was bothered by the price of VGA capture cards.  I realize there is limited need and VGA2USB works fine for the resolution of coursecast but I still was bothered by the price.

So, knowing that there are HDMI capture alternatives that are less than $100 (Avermedia HDMI capture card), I decided to test one of these with a VGA to HDMI scan converter and it worked perfectly.

I utilized an Atlona AT-HD500 VGA to HDMI scaler and set it to output at 720p and it correctly converted my 1024 X 728 signal to the appropriate resolution and it worked great.  Best yet, when I use this setup with other capture solutions, I get much better frame rate and lossless resolution.  Overall, the two devices together were still less than Epiphan's VGA2USB adapter.

Just a suggestion.

Thanks for posting this Anton! It's nice to know of some cheaper (but still good quality) alternatives to Datapath and Epiphan.

Regards,

Dave

Which of the range of VGA2USB adapters are you using and I wasn't a 100% from what you have said but I take it that you are using it with Panopto right?

Does anyone know if there are any special setup procedures to get this setup to work? I just received my Atlona VGA->HDMI Scaler and an Avermedia HD capture card. The Atlona converter works great when connected to an LCD television, but when connected to my PC, Panopto only detects a "AVermedia BDA Analog" primary and secondary video input.... there's no option for HDMI or digital input. Also, the included AVermedia software doesn't display anything on the HDMI input either. I've tried in Win 7 and XP, same results...

Make sure you set the Atlona Converter to output at 720p.  It seems to work for me with Windows 7.  I would have to go to my remote room to see which input it is connected to but I will check this for you. 

 

Neil, I only tried the low end VGA2USB capture solution.  It works very well (although on occasion, a VGA signal will start "Flashing" within panopto).

Anton,

Thanks for the confirmation. I just checked, and for some reason, I was trying to output at XGA resolution... double-checking and setting output to 720p@60 worked great. Thanks!

No problem!  It is important to use 720p@60 because the card only recognizes HD formats.   now that I think about it, I had the same issue too.  I guess I should have posted that it in my original post.

I have an MacBook Pro outputting at 720p@60 connected to an AverMedia HDMI input card.. It displays in the AverMedia software but if I use Panopto, I just get a black screen. All I get is the AVermedia BDA analog in.

Any thoughts? Thanks.
