The problem with generating audio and video separately
Most pipelines write a script, generate visuals, generate a voice-over, then try to line them up at the end. The result drifts: a line lands a beat late, a reveal happens before it's described, the cut feels off. For long-form story content, that drift compounds over an hour and breaks immersion.
One timeline, generated together
longflow plans narration and visuals against a single shared timeline. Each beat of the script carries the moment it's meant to land, and the frames are generated to hit it. The audio and the picture are never reconciled after the fact — they're built to the same clock from the start.
Why it matters for autopilot
When generation runs unattended on a cadence, you can't hand-fix sync on every episode. Locking sync into the generation step is what makes hands-off long-form viable — and it's the quality bar we hold above everything else.

longflow is in private beta — written, animated, narrated, and distributed on a cadence, with frame-accurate sync.
