I am considering a multicamera production.... ​will the cameras (and audio) be in sync?​​

Ways to connect a camera to a switcher:​

  • NDI​
  • HDMI​
  • SDI​
  • USB​

Ways to connect audio to a switcher:​

  • Direct inputs from mic/receiver to switcher​
  • Embedded audio in NDI feed​
  • Dante audio​
  • Master program from dedicated audio mixer​

First let's talk about syncing Video

  • Baseband Video will always have the lowest latency:HDMI, SDI, USB
  • NDI will have different levels of Latency:​
    • Full Bandwidth will have lowest Latency​
    • NDI HX will have varying amounts of latency ​
  • Tech Tip: Always have the same type of connecting cameras facing the same subject

Let's talk about syncing audio

  • Audio inherently has extremely low latency no matter the transmission method because it is a small file to transfer than video​
  • Most modern switchers can delay audio to match the video ​

How can I get a camera in those hard-to-reach spaces?​

NDI​

  • Just 1 Cable needed for video, power & control​
  • Perfect for retrofit applications & flexible production use​

Now you can use your Wi-Fi network when only a power outlet is available

Wireless NDI​

  • Great for older buildings where you can't run new cables​
  • Utilizes the power of NDI HX3 compression ​
  • Both Wireless PTZs and Wireless Encoders are available​
  • NETGEAR Pro AV introduced Wireless Access points for Wireless NDI​

Go truly wireless with BirdDog X4 ​or with Legacy cameras and wireless encoders​

  • 4K 60p​
  • NDI HX3​
  • WiFi 6​
  • Halo Tally ​
  • 3G SDI, HDMI, USB, Ethernet, WiFi​
  • Built in battery (6 hours)​
  • Totally wireless functionality with Battery and WiFi

Wireless NDI Encoders​ Kiloview N2

N2 NDI wireless video encoder is a professional video encoding device for NDI video production. It can encode SDI/HDMI video source into NDI|HX, through Ethernet or WiFi. The network is used for video transmission for any compatible system, equipment or software in the network, and it also supports the SRT/RTMP transmission protocol. N2 supports HDMI input.

Shogun Ultra is your gateway to amazingly fast and productive cloud workflows. So much more than a super-bright monitor recorder, it takes you to new heights of productivity and collaborative creativity. Work faster, work better.

We record long events, but our cameras split the files into multiple clips. Is there a way to record one long, uninterrupted file? ​

Atomos monitor and recorders are the solution!​

  • Take the HDMI/SDI output of your camera and record directly to Atomos device​
  • Record up to 8k 30p RAW or 4k 120p​
  • Check out our latest Atomos Video for more details!​

What if I am utilizing a Switcher workflow? 

  • Most Production System allow you to record master program as well as several other mixes of your inputs whether its baseband or IP. ​

​We do a lot of remote interviews, but our guests always look and sound terrible. What’s the best way to improve their video quality?​

Tips that we suggest to our remote guests:​

  • Have a wired network connection to the computer/camera they are using​
  • Use headphones whenever possible to minimize feedback loops​
  • Recommend using an external microphone – Built in microphones are not ideal on computers​
  • Recommend using a professional camera, whether a DSLR, PTZ or high end webcam​

Send them a camera and microphone if you can!​

  • Utilize things Like BirdDog Cloud and PTZOptics Hive studio. Send your guest a camera and tell them to connect it to the internet and you will control the camera remotely. Some ​
