Tested a new affordable mobile system for vMix 21.0.0.45 4K.

Acer Nitro V 15 BE VN7-593G-74FW
I7 7700 HQ
256 GB SSD+ 1000GB HDD
8 GB DDR4 RAM
GTX 1060 6GB
2x USB 3
1x Thunderbolt 3

Aktio Node Lite Thunderbolt 3 PCI Express Expansion Chassis
BM Decklink Duo 2
BM Decklink Minirecorder 4K

2x Elgato Camlink HDMI to USB 3

Elgato Streamdeck

Behringer UMC202 HD

The Nitro seems to have 2 USB 3 curcuits, so its posible to run the 2 Camlinks simultaneously.

Following configuarations were tested successfully:

vMix @ 1080 50p
- 2x Camlink @ 1080 50p
- 1x BM Minirecorder 4K with Akitio over Thunderbolt3
- Decklink for switching (shortcuts)
- UMC202HD Stereo

2 HD and 1 UHD input via HDMI, recording MP4 high profile @ 28mbit -hardware encoded.
6 virtual inputs from the 4k source, 2 native inputs from the Camlinks, 20 various inputs like lowerthirds, video, pictures...
Streaming to facebook @ 720 2,5mbits hardware encoded.
NDI not tested.
Testtime about 3 hours, rendertime never over 11ms, Cpu load 25-35 %...

2 HD via HDMI, 4 HD via SDI inputs @ 50p, recording MP4 high profile @ 28mbit -hardware encoded.
20 various inputs like lowerthirds, video, pictures...
Streaming to facebook @ 720 2,5mbits hardware encoded.
NDI not tested.

At first tests this notebook tended to overheat, average temperatures of 98 degrees celsius were dedected bei Core Temp.
It seems that the manufactor used a cheap and unusable cool paste.
Repasting CPU/GPU and ligthly undervolt CPU gave me -15 degrees of CPU temperature and stable performance with vMix 4k.

Conclusion:
Easy transportable and stable System with 2HD+ 1 UHD or 6 HD inputs and extendable to 9 HD inputs with an additional switcher like Roland V1HD.
Great for me...:)
