WanInfiniteTalkToVideo generates video sequences from audio input. It uses a video diffusion model, conditioned on audio features extracted from one or two speakers, to produce a latent representation of a talking head video. The node can generate a new sequence or extend an existing one using previous frames for motion context. ## Inputs ### Common Inputs | Parameter | Description | Data Type | Required | Range | | ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------- | -------- | ---------------------------------------- | | `mode` | The audio input mode. `single_speaker` uses one audio input. `two_speakers` enables the additional audio input and masks listed in the Two Speakers Inputs section. | DYNAMIC\_COMBO | Yes | `"single_speaker"`
`"two_speakers"` | | `model` | The base video diffusion model. | MODEL | Yes | - | | `model_patch` | The model patch containing audio projection layers. | MODEL\_PATCH | Yes | - | | `positive` | The positive conditioning to guide the generation. | CONDITIONING | Yes | - | | `negative` | The negative conditioning to guide the generation. | CONDITIONING | Yes | - | | `vae` | The VAE used for encoding images to and from the latent space. | VAE | Yes | - | | `width` | The width of the output video in pixels. Must be divisible by 16. (default: 832) | INT | Yes | 16 - MAX\_RESOLUTION (step 16) | | `height` | The height of the output video in pixels. Must be divisible by 16. (default: 480) | INT | Yes | 16 - MAX\_RESOLUTION (step 16) | | `length` | The number of frames to generate. (default: 81) | INT | Yes | 1 - MAX\_RESOLUTION (step 4) | | `clip_vision_output` | Optional CLIP vision output for additional conditioning. | CLIP\_VISION\_OUTPUT | No | - | | `start_image` | Optional starting image to initialize the video sequence. | IMAGE | No | - | | `audio_encoder_output_1` | The primary audio encoder output containing features for the first speaker. | AUDIO\_ENCODER\_OUTPUT | Yes | - | | `motion_frame_count` | Number of previous frames to use as motion context. (default: 9) | INT | Yes | 1 - 33 | | `audio_scale` | A scaling factor applied to the audio conditioning. (default: 1.0) | FLOAT | Yes | -10.0 - 10.0 | | `previous_frames` | Optional previous video frames to extend from. The last `motion_frame_count` frames are used as motion context. | IMAGE | No | - | ### Two Speakers Inputs The inputs in this section are shown when `mode` is set to `"two_speakers"`. | Parameter | Description | Data Type | Required | Range | | ------------------------ | --------------------------------------------------------------------------- | ---------------------- | -------- | ----- | | `audio_encoder_output_2` | The second audio encoder output containing features for the second speaker. | AUDIO\_ENCODER\_OUTPUT | No | - | | `mask_1` | Mask for the first speaker, required if using two audio inputs. | MASK | No | - | | `mask_2` | Mask for the second speaker, required if using two audio inputs. | MASK | No | - | **Parameter Constraints:** * When `mode` is set to `"two_speakers"`, `audio_encoder_output_2`, `mask_1`, and `mask_2` are required for the second speaker setup. * If `audio_encoder_output_2` is provided, both `mask_1` and `mask_2` must also be provided. * If both `mask_1` and `mask_2` are provided, `audio_encoder_output_2` must also be provided. * If `previous_frames` is provided, it must contain at least as many frames as specified by `motion_frame_count`. ## Outputs | Output Name | Description | Data Type | | ------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------ | | `model` | The patched model with audio conditioning applied. | MODEL | | `positive` | The positive conditioning, potentially modified with additional context such as a start image or CLIP vision output. | CONDITIONING | | `negative` | The negative conditioning, potentially modified with additional context. | CONDITIONING | | `latent` | The generated video sequence in latent space. | LATENT | | `trim_image` | The number of frames from the start of the motion context that should be trimmed when extending a sequence. Equals `motion_frame_count` when `previous_frames` is provided, otherwise 0. | INT | > This documentation was AI-generated.
