Hello everybody!
My use case is the following: I am doing video live production. I use my laptop as a small video mixer. To capture computer outputs I bought an Ultrastudio SDI (with a HDMI->SDI mini converter) - (e.g. to capture a presentation from a computer on stage). The Ultrastudio actually works in a way that I am able to capture the output of another computer, but the capture quality is not really overwhelming.
It's hard for me to tell why the results look the way as in the attached screenshots - seems that the capture resolution is not anything like 1080 whatsoever.
What I tried so far: Iterating thru all resolutions and refreshrates on the computer I want to capture. Always the same result.
I also borrowed a Ultrastudio Express to test direct HDMI input without the mini converter. Also the same pixeled results.
When I plug in a monitor on either of the Ultrastudios the image is crisp and fine. But not the captured image.
My Specs:
Laptop used for capturing:
Acer Travelmate 648P
Intel i7 6500U 2 x 2,5GHz
8GB RAM
NVIDIA Geforce GTX940M with 2GB of dedicated VRAM
USB 3.0 and Thunderbolt3 (USB-C)
Would be glad for any information on why I get this sloppy results and/or any hints on how to fix this.
Kind regards, Thomas Bergner
