# This is a specialized model with the following constraints on its input parameters:
|
||
# * The model outputs a sequence of keyframes rather than a video; therefore, `framewise_decoding=True` must be set.
|
||
# * When the number of keyframes is $n$, `num_frames` = 4 * (n - 1) + 1.
|
||
# * Reducing `height`, `width`, `num_frames`, or `num_inference_steps` may lead to severe artifacts or generation failure.
|
||
# * The audio file specified by `wantodance_music_path` must match the video duration, calculated as (`num_frames` / 7.5) seconds.
|
||
# * The width and height of `wantodance_reference_image` must be multiples of 16.
|
||
# * `wantodance_fps` is configurable, but since the model appears to have been trained exclusively at 7.5 FPS, setting it to other values is not recommended.
|
||
# * The first frame of `wantodance_keyframes` is the `wantodance_reference_image`, while all subsequent frames are solid black.
|
||
# * `wantodance_keyframes_mask` indicates the positions of valid frames within `wantodance_keyframes`.
