BirdDog BD4K Overview

Based on BirdDog's custom NDI silicon chip, the BirdDog 4K Quad NDI Encoder/Decoder supports up to UHD 4K/60 video input for distribution on NDI networks in full-bandwidth I-frame compression. This compact device is housed in an aircraft-grade aluminum case and features four 12G-SDI selectable inputs/outputs. An HDMI 2.0 output is available but is currently inactive until an expected future firmware update. When the output becomes active, a built-in cross converter will allow you to loop out an SDI input via the HDMI port.

Another major feature is an SFP+ expansion slot that supports SFP+ modules for fiber connectivity and Ethernet protocols from 1-10 GbE (you may require a free firmware update that's already available from BirdDog). A Tally system with a large bicolor Tally light is also built for indicating which camera is live to on-air talent. The Tally system also allows user-selectable Tally borders on loop out. The device is complete with 3.5mm audio input/output, a 4-line OLED display, and USB 3.0 interface. It can be powered by a standard power supply or over PoE+.

The 4K Quad NDI Encoder/Decoder comes with the BirdDog Comms Lite audio intercom software, which supports up to four BirdDog devices. Comms Lite is Windows compatible and offers features such as Director Push-to-Talk, Mute Camera Operator, Auto Detect NDI Sources, Monitor Camera Audio, and Shortcut to Web Console. For a more complete version of the application, an optional upgrade is available to Comms Pro. The Encoder/Decoder is also compatible with the optional BirdDog Central software, which helps you decode NDI back to SDI or HDMI.

BirdDog BD4K Reviews

Works great! IF you understand the nuances of NDI

By Jay Tee
Rated 4 out of 5
Date: 2025-11-28

This unit does exactly what you needed to do, once you get it to an up-to-date firmware. I think that was my biggest challenge with this was at first I could not find the correct firmware for it. The version five firmware that’s listed on the support page of their website, cannot be upgraded to unless you’re already on version five. The problem is these things do not ship with that new version. They shipped with an extremely old buggy version 1.1 that will not work. However, if you go to their previous releases, you will find up to a version 21. There’s about 10 previous versions on there, and you will have to upgrade the unit through each version one by one to get it to want to work with the newest version 21. Once you do that, the unit actually works amazing. Now understand this is a full NDI encoder, so those expecting it to be HX need to look for something else. Additionally, if you’re looking to use this with V-Mix, VMIX only outputs full NDI. There is a trick documented online to get HX feeds, but it adds some delay. So yeah it does take a little TLC to get this thing to function correctly. But if your goal is to use full NDI, and you have a network that supports it, once you get through the lack of documentation and the firmware weirdness, this QUAD 4K is rock solid and I’ve never had a single problem on a show.

Finally working reliably

I had purchased these units about 18 months ago and they were totally unusable, and ended up returning them (the other review here is mine). They've finally got this thing working reliably and I use it in a 24/7 environment without issue. Did knock 1 star as they originally advertised it as it could be a mix of encode and decode, but that eventually changed to all of one or the other.

Does this equipment work or not? Also, based on BD Website, the BNCs can be independently assigned as an encoder or decoder; is this not true?
Asked by: Matt
The 4K Quads will be able to do that, once the final firmware is released. It is not in that current state, but eventually that feature is planned to be on the QUAD. Right now, you can ENCODE all or DECODE all.

Can one unit simultaneously provide 2 ins & 2 outs?
Asked by: Kenneth
As of 5/8/2021 the firmware still does not support simultaneous encode/decode on the SDI ports. The SFP+ port is disabled limiting the interface to 1gb/sec ethernet. The HDMI jack also is not supported for use as stated in the product description. Major features that make this box worth its purchase price are all "coming soon". Very disappointing as this box is a great concept with some exciting features, once they actually are useable as described.
