The Coherence Challenge of AI Song-to-Video

The author experimented with generating videos purely from audio tracks using AI. The core takeaway: **technically, generating clips is possible, but the real challenge is stringing them together into a music video with narrative or thematic consistency**. ### Main Issues - Many models can only produce "good-looking shots", but lack a coherent visual story between scenes. - A common flaw is over-reliance on literal keyword-to-screen translation—for example, if the lyrics mention "sun", it forcefully generates a sun, rather than a more emotionally expressive sunrise or sunset. - The true difficulty lies not in aligning visuals with the beat, but in understanding the song's **subtext, emotional arc, and atmosphere**. ### Author's Perspective - **The higher the automation, the weaker the controllability**; - **The stronger the controllability, the closer it gets to traditional editing**; - The ideal solution is for AI to make smart suggestions based on the music first, followed by human artistic fine-tuning. They also tested **freebeat**, noting that it does a decent job at **beat-synced cuts**, but **visual storytelling** remains its weak point.
