Long story short i have a Sony fdr-ax33 with hdmi mini output ( i have the mini to normal cable converter)
and i have another old camera using the analog cable AV.
could u point me out a working external device (preferable USB)
that i can connect both HDMI and AV and use the at the same time on vmix?

Hi
I don't think such a device exists on USB.
BTW in general it's not possible to mix analog & HD signals, so you'd have to use the Sony in SD (with a HDMI2Analog converter if this cam hasn't got an analog output)
AFAIK only Yuan offers a multi input USB dongle (which outputs H.264, not uncompressed signals). But I don't know if it accepts HD and SD at the same time. I doubt it will. And I also doubt it takes analog in.
Maybe some other guys know a magical box for you ?

thanks for the reply..
Why would i convert my HDMI output to analog via the HDMI2Analog? there are usb capture devices that can capture hdmi inputs.. the sony has no analog output only hdmi
Rest of it i got the point.. maybe i will get a usb to analog
and a usb to hdmi capture device..

Quote:Why would i convert my HDMI output to analog via the HDMI2Analog? if you want both cams on a single capture device at the same time. HDMI is digital only and FDR-AX33 can't output SD. If you have 2 USB dongles, 1 for analog + 1 for HDMI (like the Magewell for example) then you don't need a converter to capture, but you will need to downscale your sony signal to the same resolution as the other cam (PAL I guess so 720x576). Also You might need to convert from 16/9 to 4/3 (depending on your old cam specs)

There is the Inogeni Share 1 https://inogeni.com/share-apps/You can input 1 HDMI plus 1 HDMI/DVI, or Composite input. It requires an i5 CPU according to Inogeni. But it is much more expensive than the solution proposed by DWAM. A Magewell and an analog capture device such as the EZ CapTV would save you considerable money over the Inogeni Share 1.

There's also the Magewell XI104XUSB USB3 box which has one HD channel (DVI/HDMI/VGA/YUV) plus four SD analogue composite video channels. However, I think it's been discontinued due to the general move away from SD/analogue video, but if you can find one somewhere it would certainly do the job, along with the XI200XUSB box which has two multi-format DVI inputs which can handle either HDMI or composite SD via the included adapter cables.

Hi thanks for ur answer.. yes these magewell will do the job.. but 700$?? thats way over my head.. max budget is 200. if i have to buy 2 seperate capture device, 1 for analog - 1 for the hdmi
budget is 100 each max.

I just found a clone of Magewell HDMI dongle at 89 euro https://www.amazon.fr/Di...id%C3%A9o/dp/B01I0C5ZYU/Can't tell if it's reliable or not. It's up to you... For analog dongles, there are plenty but in general, cheap (or even less cheap) models are not very accurate and most of the time you will get audio/video desync.

DWAM why should i downscale the quality of my hdmi if i am streaming to 1080p? so it can match the other camera and have the "same" quality?
i will propably get 2 capture devices.. i will try my luck with an AV capture device that costs about 14euro.. just for the test. and i will purchase the other one soonish.

Because trying to upscale your SD to HD will give crappy, blurry results, especially with a 14 euro capture card ! ;o).
I'm not even sure vMix can load a SD cam into a 1080p project. Never tried...
