on

On this weeks Videoguys Live, James hosts Ask the Videoguys where he will give Technical Advice for your production as well as sharing our Top Videoguys Tech Tips. James will share tips on frame rates/bit rates for live streaming, differences between 3G, 6G, & 12G SDI, finding the IP address of NDI PTZ Cameras, setting up a REMI production, differences between RAID 0, 1, 5, & 6, on the go storage solutions, and more!

What streaming resolutions/frame rates do different CDNs recommend? What bitrate should I use?

Tech Tip: use the highest common denominator for resolution and frame rates when streaming to multiple destinations if your encoder doesn’t allow different settings


What is the difference between 3G, 6G and 12G SDI? And why would I choose SDI over HDMI?​




  • 3G SDI - Up to 1080 60 ​


  • 6G SDI - Up to 4k 30 ​


  • 12G SDI - Up to 4k 60

Tech Tip: Consider using AV over IP as it is the best of both worlds giving long cable runs, on a common cable with a locking mechanism!​


How do I find the IP address of my NDI PTZ camera and change it to either DHCP or Static?




  1. Download NDI Tools​


  2. Open NDI Analysis​


  3. Plug camera into network​


  4. Run the "NDIAnalysis.exe /find" command​

  5. Find the IP address of the desired camera

  6. ​Plug in external Network Adaptor to computer​

  7. In Network settings on computer change Network adapter settings to be on the same range as the camera​


    1. Select “Change Network Adaptors”​

    2. Right click on USB Ethernet​

    3. Select “TCP/IPv4”​

    4. Change Ip address to be same range as range from NDI Analysis​


  8. Plug camera into network adaptor and turn on camera

  9. Now you can access the cameras web gui to change camera settings to DHCP or a Fixed Ip of your choosing​


  10. ​Once DHCP or Static is selected, unplug the camera and plug into Network Switch​​





For complete Remi control, what products do you recommend starting with?



  • PTZOptics​​ Hive Studio​​

  • BirdDog Cloud​​

  • Epiphan Connect​​

  • NDI Bridge​​

  • LiveU Studio


  • Now Is the Perfect time to get into Remote Productions with so many workflows!​



What is the difference between Raid 0, Raid 1, Raid 5 and Raid 6?​




  • RAID 0 (Striping): Data is stored evenly across the number of disks in the array. This process is called disk striping and involves splitting data into blocks and writing it simultaneously/sequentially on multiple disks. It provides improved performance but no redundancy


  • RAID 1 (Mirroring): ​Data is duplicated and stored on each drive. This process is called mirroring, and it ensures you won’t lose your files if a drive fails. It provides redundancy but no performance gain


  • RAID 5: ​Uses disk striping with parity. It sets aside “one drive’s worth” of disk space for parity data. RAID 5 requires fewer hard drives but can provide protection against a single drive failure


  • RAID 6: ​Similar to RAID 5 but introduces dual parity. It sets aside “two drives’ worth” of disk space for parity data. RAID 6 can provide protection against two simultaneous drive failures​



What is the best storage system for storage on the go?​




  • Definition: Portable rugged SSD drives are high-capacity, high-speed storage devices that are designed to withstand harsh conditions.​


  • Use Cases: Ideal for outdoor use, travel, and situations where data might be exposed to rough handling or environmental hazards.​


  • Advantages: They offer the speed of SSDs, combined with a design that is resistant to shock, dust, and water.​


  • We can help you find the perfect drive for your on-the-go needs, whether it's waterproof, dust proof, shock proof or all of the above​
