yesTool

yesTool is an audio to video tool that turns a song and a still image into an animated lip-sync performance. A web tool that animates a still image into a lip-syncing singer for an uploaded track, using the Wan S2V model with emotion-aware facial animation.

yesTool's AI Music Video generator takes a song file and a single still image and turns them into an animated performance where the character appears to sing the track. The engine is Wan S2V, a speech-to-video model with 14B parameters that the team has adapted for music. A Wav2Vec-based analysis pass reads the vocal line, rhythm and emotional tone of the upload, then drives mouth shapes, facial expressions and body motion so the animation stays locked to the audio rather than drifting into generic movement. The workflow is deliberately short. The user uploads audio alongside a portrait, illustration, cartoon or any character design, picks a framing (portrait close-up, bust or full body) and an aspect ratio from the presets on the page, then generates. Rendering runs in the cloud at 480P or 720P, so the machine on the other end does not need a GPU, and the site reports turnaround in the range of a few minutes depending on song length and chosen quality. A roster of preset performers (Mr Cat, Punk Rebel, Opera Empress and others) is offered for anyone who does not arrive with artwork of their own. The tool suits independent musicians who want a visual for a single without commissioning animation, social media creators building lyric-style clips, and small labels or band projects that need separate performances for each member. Because only a still image is required, it also works for producers who would rather animate a mascot or painted character than appear on camera. Instrumentals are supported too, though the emotion-driven movement is a weaker fit there than lip sync is for vocal tracks. The closest alternatives are avatar and talking-head platforms built for narration, which tend to produce a seated speaker rather than a staged performance, and full text-to-video models, which generate scenes but rarely bind a mouth to a specific vocal track. yesTool's narrow focus on the singing case is the differentiator. Commercial use of the output is stated as permitted, including music releases and monetized video platforms, which matters for creators publishing on YouTube or TikTok.
