This is the list you bookmark. If your camera’s on it, you need 12G cables. No wiggle room.
What 12G-SDI actually means
12G-SDI (SMPTE ST 2082) pushes 11.88 Gbps over a single cable. That’s enough for 4K/UHD up to 60fps, DCI 4K (4096 × 2160), large format resolutions at full bandwidth, HDR without compromises, and high frame rates without splitting signals. No quad-link spaghetti. No dual-link headaches. One cable. Full fat signal.

The rental house test
Walk into any top-tier rental house today and pull a high-end package. You’re walking out with an ALEXA Mini LF, ALEXA 35, RED V-RAPTOR, or Sony VENICE 2. Every single one outputs 12G. Every single one expects 12G cables to deliver full-resolution signal to your recorder or monitor.
Show up with 3G cables and you’re either downscaling your gorgeous 4K+ image to 1080p (which is like buying a Porsche and driving it in first gear) or making trips back to the truck while the AD’s patience evaporates.
Don’t forget the other end of the cable
Your camera might spit 12G all day long, but can your monitor actually catch it?
12G-SDI monitors include SmallHD Cine series, TVLogic LUM series, Sony BVM-HX series, Flanders Scientific, and Atomos Ninja V+ / Shogun Ultra.
12G-SDI recorders include Atomos Shogun Ultra, Blackmagic Video Assist 12G, Blackmagic HyperDeck Studio 4K Pro, Sound Devices PIX 270i, and Convergent Design Odyssey 7Q+ (with upgrade).
If your monitor or recorder taps out at 3G, you’re bottlenecked. You get a downconverted output regardless of how beastly your camera is.
The investment argument
12G isn’t just for big-budget features anymore. The RED KOMODO brought 12G to the sub-$10K price point. The ALEXA 35 is becoming the default for anything with a proper budget. Sony’s BURANO is pushing 12G into documentary and indie territory.
If you’re buying cables, monitors, or any infrastructure today, 12G capability is table stakes. You might not need it this week, but you will. Buying the same gear twice because you cheaped out the first time is the most expensive way to save money.
Quick reference
| Camera | 12G Outputs | Max Resolution |
|---|---|---|
| RED KOMODO | 1 | 6K |
| RED V-RAPTOR | 2 | 8K |
| ALEXA Mini LF | 1 (2 w/ accessory) | 4.5K |
| ALEXA 35 | 2 | 4.6K |
| VENICE 2 | 1 | 8.6K |
| Sony BURANO | 1 | 8K |
| Canon C500 II | 1 | 5.9K |
| Blackmagic URSA 12K | 1 | 12K |
Bottom line
If you’re touching anything made in the last 3-4 years at the professional level, you’re in 12G territory. Plan your cable bag accordingly.
You can use the 3G output if you want, but you’re paying for resolution and throwing it in the dumpster. Somebody’s budget bought that resolution. Don’t waste it because your cables couldn’t keep up.
