Video acquisition

Hello,
i would like to know what is the best solution (easier and cheapest) to connect 4 caméras with SDI 3G on my computer and use this 4 sources in software as OBS STUDIO or RESOLUME AVENUE ?

How BlackMagic can help me to do that ?

I thank you in advance for your lights.

The BMD Decklink Duo 2 should work. https://www.bhphotovideo.com/c/product/1247779-REG/blackmagic_design_bdlkduo2_decklink_duo_2.html

Keep in mind the processing power a computer needs for that many inputs, transcoding, streaming, encoding, recording, hard drive speed, etc.

You may consider a hardware solution.

Thanks Kevin !

Allow me to ask you if you do not know a solution external to the computer ?

Thanks anyway for your help.

Use a dedicated switcher like the ATEM Television Studio HD. https://www.blackmagicdesign.com/products/atemtelevisionstudio/techspecs/W-APS-08

Use a BMD HyperDeck Studio Mini to record. A Teradek VidiU Pro to stream/record.

Use your computer to control the switcher and build graphics. Even use PowerPoint as an input for graphics, video playback, live titles and lower thirds with the SimpleSupers.com app.

You will have a lot of flexibility to add cameras in the future, or other inputs if needed. The hardware does the work and frees your computer up for other tasks.
