Prompt Scheduling

Encode a schedule of prompts with automatic interpolation.

Schedule format

Schedules support JSON and Python-like formats. Frame 0 is the first frame and max_frames - 1 is the last.

"0": "blue rock on mountain",
"16": "green rock in lake"

0 = "blue rock on mountain",
16 = "green rock in lake"

Prompts must be enclosed in double quotes. Prompt portions may use keys supplied through values_replace.

Single: A positive integer such as 0 or 2 selects that frame. A negative integer such as -1 or -5 selects from the end (-1 is the last frame). A decimal such as 0.5 or 1.0 selects a relative position (0.5 is halfway and 1.0 is the last frame).
Range: start:end uses an uninterpolated prompt from the included start index to the excluded end index. Examples: 0:12, 0:-5, 2:0.5.
Hold: A colon after one index stops interpolation until the next supplied index. Examples: 0:, 0.5:, 16:.

Input	Description
`prompts`	The prompt schedule.
`clip`	CLIP used to encode prompts.
`prepend_text`	Optional text added before every prompt.
`append_text`	Optional text added after every prompt.
`values_replace`	Optional value schedules substituted for keys written as `some_key` in prompts.
`print_schedule`	Print the resulting schedule when enabled.
`max_length`	Intended schedule length. At 0, the largest schedule index determines the length, but negative and decimal relative indices are disabled.
`tensor_interp`	Prompt-conditioning interpolation method; defaults to linear interpolation.
