Transcoding Ins and Outs (VidiU Go vs 700 series/T-Rax)

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.

Launching a Transcoding Engine for 600-700 series (Cube, Slice, Bond) or T-Rax:

1.  Log into your Core account.
2.  Open the Engines menu on the left-hand side and select Transcoding Engines.
3.  Click Launch, then choose a region closest to the location of the encoder you intend to use.
4.  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.
5.  Open the Cloud Services menu, then select Core.
6.  Enter your credentials, then tap on the Connection tab to display a list of available transcoding engines.
7.  Select your transcoding engine, then tap Apply.
8.  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.
9. Under the Info tab, you will see the engine your encoder is associated with.
   
   
   

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:

1.  From the Core dashboard, select your device, then tap the gear icon to enter the Settings menu.
2.  Tap the Codec button and select HEVC or H.264.
3.  Tap Apply at the bottom of the Settings menu.

NOTE: VidiU Go can also be connected the same way as Cube/Slice/Bond or T-rax to the separate Transcoding Engine. Both ways are good, just depends on which way is more suitable for the customer.

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: please, see this article to make sure which is the best way to set your Transcoding Engine to go offline and stop being charged.

• Device/video limits: Transcoding engines support 1 device with up to 1080p @60 fps video. Maximum inbound video bitrate is approximately 12mbps.
