In situations where bandwidth is limited, using HEVC will preserve the video quality while using lower bitrates. Teradek’s HEVC encoders using Core require a transcoding engine to convert video back to H.264 for delivery to streaming platforms that don’t support HEVC.

Activating Transcoding on VidiU Go:
For VidiU Go, Core has built in transcoding functionality that automatically converts HEVC video back to H.264 for delivery to your RTMP destination. No transcoding engine is needed. There is a $3/hour charge for this service. To switch between HEVC and H.264:
- From the Core dashboard, select your device, then tap the gear icon to enter the Settings menu.
- Tap the Codec button and select HEVC or H.264.
- Tap Apply at the bottom of the Settings menu.
Launching a Transcoding Engine for 700 series (Cube, Slice, Bond) or T-Rax:
- Log into your Core account.
- Open the Engines menu on the left-hand side and select Transcoding Engines.
- Click Launch, then choose a region closest to the location of the encoder you intend to use.
- Navigate to your device's web user interface (web UI) by entering the network IP address into your browser’s navigation bar. You can obtain the IP address from the front panel by pressing down on the Menu joystick/control dial.
- Open the Cloud Services menu, then select Core.
- Enter your credentials, then tap on the Connection tab to display a list of available transcoding engines.
- Select your transcoding engine, then tap Apply.
- To verify your encoder is associated with the correct transcoding engine, navigate back to
the Core web UI and select your source from either the Dashboard or Sources menu. - Under the Info tab, you will see the engine your encoder is associated with.
Things you should know:
- Transcoded output video quality and bitrate: Values are not configurable, but are matched to the detected video resolution, frame rate, and keyframe interval. Approximate bitrates are:
- 1920x1080: 12 Mbps
- 1280x720: 5.3 Mbps
- 960x540: 3 Mbps
- 854x480: 2.4 Mbps
- Transcoding engine uptime: For Cube/Slice/Bond, the server starts when a connection request is received from the encoder. After startup, it is billed by the hour, rounded up to the nearest hour. The server stops 20 minutes after all connections to the server are terminated.
- Device/video limits: Transcoding engines support 1 device with up to 1080p @60 fps video. Maximum inbound video bitrate is approximately 12mbps.
