Static Ladders

There are some situations where the predictability of your output outweighs other considerations, such as cost — for example, when you want to ensure a similar experience across all devices. In such cases, LightFlow allows you to define custom static ladders.

Adding a Rendition

To add a rendition to the Static Ladder profile, click Add rendition and then configure the following parameters:

• Packaging: MP4, MP3, MPEG-DASH, HLS, MSS
• Video bitrate (Kbps): Target bitrate
• Video Width: Number of pixels
• Video Height: Number of pixels
• Video FPS: Number of frames per second (FPS=0 for passthrough)
• Video Codec: H264, VP9, NONE
• H.264 Profile: Baseline, Main, High
• Audio Codec: AAC, MP3
• Audio Bitrate (Kbps): Maximum value is 384 Kbps
• Audio Channels: Passthrough, or up to 8 audio channels
• Audio Sample Rate: Passthrough, or one of thirteen discrete options from 7350 to 96000 Hz
