AUDIO/VIDEO SETTINGS
● DEINTERLACER - The Deinterlacer converts interlaced video into progressive video before
streaming, improving the appearance of video that has been scaled down
from the original input resolution. In addition to supporting scaled down
interlaced video, deinterlacing is useful when streaming to the Internet or
mobile devices.
● RESOLUTION - Maintain the input’s native resolution (Auto), or select from a list of resolutions.
● BITRATE
SELECTION
- Select from a list of bitrate figures, or manually enter a custom bitrate.
● BITRATE (kbps) - Select your stream’s target bitrate. Lower bitrates require less
bandwidth and may allow for a more stable stream while higher bitrates
oer better video quality, but require more network bandwidth.
● FRAME RATE
SELECTION
- Select Auto to maintain the input frame rate, or select Custom to choose a
frame rate that matches the exact figure or a fraction of the input frame rate.
● KEY FRAME
INTERVAL
- Adjust the amount of time between full picture refreshes.

Analog audio.
● MUTE - Turn o Audio.

NETWORK
Vidiu X allows you to connect and stream to
the Internet by utilizing one of several network
interfaces. Navigate to Settings>Network
(Network Settings from the front panel), then
make a selection.
NETWORK SETTINGS
● SSL/TLS
ENCRYPTION
- SSL (Secure Sockets Layer), and its successor, TLS (Transport Layer Security),
are encryption protocols used to protect the confidentiality and integrity of any
data transmitted over the Internet. Use this option to enable or disable
SSL/TLS encryption.
● WIRED
- A wired Ethernet connection is typically the most reliable means for
connecting to a network, as you don’t have to deal with the instability of a
Wi-Fi or cellular connection. Connect an Ethernet cable to Vidiu X, select
Wired, then choose a configuration mode:
● Dynamic (DHCP):When set to DHCP, Vidiu X will request an IP address and
network configuration from the network’s DHCP server.
● Static: When set to Static, you will need to manually configure the IP
address, subnet mask, gateway, and DNS server to connect to the network.
● WIFI - Although an Ethernet connection is the most reliable method of connecting
to a network, a Wi-Fi connection may be more convenient, especially if an
Ethernet connection is unavailable. There are two wireless modes available:
● Access Point (AP) Mode: Vidiu acts as its own dual band access point,
allowing you to connect your device directly to Vidiu’s AP network.
● Client Mode: Vidiu and your mobile device connect to the same local
wireless network. Access Client Mode, scan for available networks or
connect to a previously saved network, then enter your credentials.
● MODEM - A USB modem allows you to broadcast wherever a cell connection is
available. Vidiu X automatically detects and supports many modems using
Auto mode. Custom mode allows you to manually configure a modem if it’s
not automatically detected. Available configuration modes are Composite,
and Ethernet.

17
● FIRMWARE - Check for new updates and upgrade Vidiu X’s firmware to the latest version.
If an update is available, simply follow the prompts to complete the firmware
update.
● SECURITY - Add, change, or delete your password.
● DATE & TIME - Enter an NTP link to automatically synchronize the time and date.
● ABOUT - Display Vidiu X’s model and serial number.
● RESET/IMPORT
& EXPORT
- Factory Reset: Restore Vidiu X to its original settings.
Import/Export: Import or export Vidiu X user settings to another Vidiu X unit.
These files can be used by a dierent Vidiu X to replicate the configuration.
Additionally, the export settings feature can be used for troubleshooting.
● LOG OUT
SESSIONS
- Log out of one or all sessions.
● DIAGNOSTICS - Generate a diagnostic report for your Vidiu X. Diagnostic reports can be used
by Teradek’s support team to assist during troubleshooting.
● REBOOT - Restart Vidiu X.
SYSTEM
Essential system functions, including factory
reset, firmware upgrade, and diagnostics
reports can be performed from the System
menu in the web UI.

MY FIREWALL/ROUTER IS BLOCKING RTMP STREAMING.
Vidiu X uses a set of ports for RTMP streaming. Make sure the required ports are allowed
through your firewall or router. The list can be found at https://support.teradek.com/hc/en-us/
articles/226177168.
WHAT ARE THE SUPPORTED RESOLUTIONS FOR EACH SOCIAL MEDIA CDN?
Every live streaming platform’s specifications are dierent, and generally change over time. Visit your
streaming platform’s website to find supported resolutions.
WHY IS MY STREAM SUDDENLY CHOPPING WHILE STREAMING?
Intermittent Wi-Fi connections can cause instability even when streaming over Ethernet. If you
encounter issues while streaming over Ethernet, disabling Wi-Fi may help. To fix this:
1. Scroll to Network Settings.
2. Select Wi-Fi.
3. Select Client. Turn Client mode to O.
WHY DOES YOUTUBE TELL ME MY BITRATE IS TOO LOW?
Vidiu X is preconfigured to use adaptive bitrate which changes according to the user’s bandwidth. This
means that the bitrates can sometimes jump or dip depending on the stream, prompting a message
from YouTube. While this operation is completely normal, it may cause a message to appear on the
YouTube event control room page.
CONFIGURING VIDIU X VIA FRONT PANEL IS DIFFICULT.
We recommend using Vidiu X’s web interface or the Vidiu app for configuring Vidiu X. It’s much
faster and simpler. To connect to the app, connect Vidiu and your cellular device to the same wireless
network. Vidiu will automatically appear in the app.
To connect using the web interface, find your Vidiu’s IP address from the front panel. Type this
address into your web browser. You will be connected to your Vidiu and can change settings
accordingly.
I’VE PRESSED THE START/STOP BUTTON TO GO LIVE, BUT MY STREAM IS NOT LIVE.
Some streaming networks such as Periscope, YouTube events, and Facebook Pages may require
additional steps to publish your stream.. This depends on the CDN’s workflow. Remember to go live
on both Vidiu and destination page to fully start streaming.
