Wan2.2 IS2V

Similar to Bernini-R-S2V, added speech-driven lip-sync to Wan 2.2 image-to-video checkpoints. Painted masks let you target one face or two speakers in sequence for simple dialog without audio bleeding across the whole frame.

It is not state-of-the-art audio-to-video, but it removes the need for post-processing lip-sync or a separate speech model just to get a talking head from Wan I2V. For basic talking-head clips, or longer videos built from short image+audio segments, it is a handy all-in-one option on top of Wan 2.2 I2V.

Wan IS2V Dual Speaker custom node handles the full I2V path (start_image, concat mask/latent, optional CLIP vision) plus masked S2V audio.

Inputs

Input	Required	Description
`audio_1`	no	Encoded mono audio for speaker 1
`mask_1`	if `audio_1`	Painted mask on the input image. Painted over = lip-sync region for speaker 1.
`audio_2`	no	Encoded mono audio for speaker 2 (dialog)
`mask_2`	if `audio_2`	Lip-sync region for speaker 2
`speaker_2_start_frame`	no	When speaker 2 begins (default `-1` = auto after speaker 1 ends)
`mask_crossfade_frames`	no	Soft blend between speaker masks (default 4, `0` = hard cut)
`audio_inject_scale`	no	Strength of audio injection inside the mask (default 1.0)
