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.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% similarUnverifiedFine-grained professional editing such as cinematic-level color grading and complex multi-track audio mixing will still require assistance from traditional tools in the short term.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.72% similar
