MuseTalk.app

MuseTalk.app is an independently operated web service that uses MuseTalk to synchronize mouth movement in an existing video with a separate audio recording. Upload an MP4 video and a WAV or MP3 audio file, choose the portion to process, and review the generated clip with sound before downloading it. The service is designed for footage with a visible speaker, such as presentations, interviews, narration and video localization. Results depend on the source footage and audio, so users should review the mouth movement and timing. Users must have permission to use their footage and audio. The website provides examples showing source inputs and real generated outputs, along with information about the source material and limitations. An account is required to create a clip. Newly verified accounts receive 10 credits once, valid for 30 days; users can also manually claim daily credits. Paid credit packs and subscriptions are available. Each generated second costs one credit, subject to frame alignment and rounding. Clips are processed privately, and downloads use short-lived links. MuseTalk.app is not affiliated with the MuseTalk research team and links to the upstream open-source project. The browser workflow brings the video and replacement audio together in one workspace. Visitors can review examples before signing in, compare footage with a generated result, and read the conditions under which each example was made. The examples illustrate particular outputs rather than guaranteeing results for every recording. For best results, use a clear view of the speaker and an audio recording that fits the intended segment. The service does not provide a transcript or synthesize a voice as part of the MuseTalk lip-sync workflow. Pricing and credit terms are available on the website. Technical failures release reserved credits, while completed jobs deliver a downloadable result. The product is intended for creators who already have footage and a replacement recording and want to inspect the result before using it.
