VerifiedTraditional 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.73% similarUnverifiedLip-sync detection methods are designed specifically for static, frontal videos, and perform poorly in dynamic, non-frontal or in-the-wild recording scenarios; detection performance collapses when the speaker turns their head more than about 45 degrees, is occluded, or when the resolution is insufficient.73% similarUnverifiedExisting audio-video joint generation methods rely heavily on paired corpora, yet paired data is scarce in joint generation and editing scenarios.73% similarVerifiedLip-sync video generation remains a difficult challenge in the industry, as it requires frame-level precision with dual alignment of local inpainting and audio timing.72% similar
