ABR

When creating a media engine, you need to specify an ABR ladder. This ladder contains all the separate rungs with a resolution, bitrate and framerate. Since this ladder has impact on pricing and is difficult to get right, setting up available ABR ladders is done during onboarding. If later on new ladders are needed, don't hesitate to contact us.

Important considerations

• Frame rate — the frame rate of the encoder and the channel configuration should match (suggested values: 25, 29.97, 30, 50, 59.94 or 60 fps). Mismatches may lead to information loss and stalls.
• Ingest bitrate — the encoder bitrate should be at least as high as the highest rung of the ABR ladder so the transcoder receives a high-quality source for all output qualities.
