# This is a specialized model with the following constraints on its input parameters:
|
||
# * The model renders and outputs video based on a sequence of keyframes; therefore, `wantodance_keyframes` must be provided correctly.
|
||
# * If you need to generate a long video, please generate it in segments, and ensure that `wantodance_music_path`, `wantodance_keyframes`, and `wantodance_keyframes_mask` are properly split accordingly.
|
||
# * The audio file specified by `wantodance_music_path` must match the video duration, calculated as (`num_frames` / 30) 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 30 FPS, setting it to other values is not recommended.
|
||
# * In `wantodance_keyframes`, frames that are not keyframes should be solid black.
|
||
# * `wantodance_keyframes_mask` indicates the positions of valid frames within `wantodance_keyframes`.
