Adding secondary audio/video streams (PiP)
DoStudio Authoring supports a secondary video track to create a picture-in-picture (PiP) effect. In this
document, we will sometimes refer to the secondary audio/video tracks as PiP tracks. You can add multiple
secondary audio tracks to your PiP track. You can not add subtitles to the PiP track.
You can add multiple secondary video tracks to a title and turn their visibility on and off using actions.
Maximum bit rate for secondary video stream
The total video bit rate value of primary video and secondary video streams (including subtitles) must be
less than or equal to 38 Mbps.
Maximum video bit rate for secondary video streams must be less than or equal to 7.6 Mbps.
When using a secondary video track, we recommend encoding your primary video track at a maximum bit
rate of 18 Mbps.
We recommend that you encode your secondary video in standard definition at a maximum bit rate of 5
Mbps. In order to create two secondary video streams and stay within the prescribed buffer, you should use
standard definition video encoded at 3.7 Mbps.
