Available options:
pcm16, pcm32, wav, mp3, ogg Turns off the face restoration pass on legacy faces.
Width of the video in pixels, Trinity-2 faces only (the others keep their own frame size). At least 512, and with streaming_height one of 1:1, 16:9 or 9:16, otherwise a 422. A canvas larger than the avatar's frame is padded with its background; a smaller one crops a window out of it.
Required range:
x >= 512Height of the video in pixels. See streaming_width.
Required range:
x >= 512Where the avatar sits across the canvas, from 0 (left) to 1 (right). Trinity-2 only.
Required range:
0 <= x <= 1Where the avatar sits down the canvas, from 0 (top) to 1 (bottom). Trinity-2 only.
Required range:
0 <= x <= 1The camera the video starts with, on top of the avatar's own framing. Trinity-2 only. Leave it out to keep the avatar's framing.
Show child attributes
Show child attributes
One of your uploaded backgrounds, by the id POST /assets/backgrounds returned, to show behind the avatar, cropped to fill the canvas. Trinity-2 only. Leave it out for the avatar's own. An id that is not one of your account's is dropped with a warning, and the video uses the avatar's own. An image is not accepted: upload it first.
One of your uploaded foregrounds, by the id POST /assets/foregrounds returned, laid over the avatar through its transparency and cropped to fill the canvas. Trinity-2 only; otherwise as background_id.
