UnverifiedExisting audio-video joint generation methods rely heavily on paired corpora, yet paired data is scarce in joint generation and editing scenarios.78% similarVerifiedTraditional cascaded architectures generate video before adding audio, which leads to problems such as audio-video desynchronization, lip-sync mismatches, and ambient sound being out of step with on-screen actions.76% similarUnverifiedFor videos that are primarily voiceover-based rather than on-camera presentations, the lip-sync feature can be skipped to reduce costs, as lip-sync increases costs and significantly extends processing time.75% similarUnverifiedIn audio-driven video generation, the beginning of the video tends to align well with the audio beat, but the degree of alignment gradually decreases in the second half.74% similarUnverifiedLip sync refers to the technology that precisely aligns the mouth movements of people in a video with the audio speech.73% similar
