Setting up multi-capture to disk setup

I'm trying to spec out a system, and am hoping someone here can let me know if I'm on the right track or not. I want 4 cameras capturing to files on my local machine, with an externally generated timecode signal. It looks to me like I could use four Micro Studio Camera 4K's feeding over SDI to four DeckLink SDI 4K cards. Media Express looks promising as software to capture to file on disk, but I'm not sure if it can capture four streams simultaneously - is that possible? Also, can I provide a timecode signal through the RS-422 port on the DeckLink cards?

Any advice is appreciated - I've done a lot of work with video manipulation in the past but I'm just getting my feet wet with pro recording tools. Thanks!

Get a tool like Vmix. They have multiple capture options. But there are more out there.

If you would only do 3G-sdi i would recommend to buy a Decklink Duo 2. This is 1 card that can capture 4 inputs at the same time.



As for timecode.. This is already embedded in the SDI signal from the camera. So you need to put that timecode to the camera and set the camera on LTC input.

If you want to capture 4x 4K (Hence Decklink 4K) you are looking at a serious monster machine with a lot of SSD's and transfer speeds between them. Also you might get in trouble with bandwidth issues on your motherboard as often PCI-E busses are shared for 2 or more slots.
Which can lead to instability issues if you have 4 cards pumping out 4K signals into your motherboard.

Thanks for the recommendation on Vmix - I'll check it out. I do want to capture at 4k, and I've done some preliminary specs for disk I/O necessary to support it. The one thing I'm still not sure about is how much CPU/GPU will be necessary to be able to encode 4x 4k streams on the fly, but I'll have to play that by ear once I have some actual equipment to test with.
