Generate AI B-roll inside Premiere Pro with Seedance 2 and Kling 3

B-roll is a rhythm problem, not a research project. When you leave Premiere to hunt stock or prompt in a web app, you lose the feel of the cut — pacing, music, and the speaker's energy on either side of the gap. A sixty-second generation loop only works if it starts from the gap you are staring at on the timeline.

Chat Video Pro treats video generation as an editorial action: identify the hole, choose a model, optionally capture a reference frame from a nearby shot, generate, preview in Library, drag to the sequence. Wholesale billing through our [integrated video generation features](/products) means you fund FAL when a project needs shots instead of stacking monthly credits across [alternative platforms like Higgsfield](/compare/chat-video-pro-vs-higgs-field). The Usage panel in Gear shows what you spent in the last day, week, and month so client pass-through lines stay honest.

The mental model is the opposite of stock: you are not searching a library for something close enough. You are briefing a cinematographer who can only see the mood of the cut around the gap. That is why editors describe the camera move, the weather, and the light temperature instead of writing marketing adjectives. When the first take is wrong, you adjust one lever — wider framing, slower push, different time of day — and regenerate without rebuilding a folder of downloads.

Seedance 2 is the default when no faces need to carry the shot. Cityscapes, coastlines, fog, neon rain, empty interiors, product reveals, and abstract motion all land in the territory where it is strongest — up to fifteen seconds at 1080p with ambient audio baked in so many clips arrive mix-ready.

Prompt with camera language editors already use: slow push-in, aerial drift, static wide, shallow product focus. Describe light and weather literally — "golden hour through office windows" beats "warm vibe." Seedance 2 Reference Mode accepts multiple reference images and audio references when you need a series of shots to share the same sonic environment.

The honest limitation: close-up people are not its best lane. When a human subject must read clearly in b-roll, switch to Kling 3.0 rather than fighting the wrong model. For dialogue-forward character shots the Gitbook decision table points to Veo 3.1; for high-speed action plates, Hailuo 2.3 is the alternate when motion blur and athletic movement dominate the brief.

Practical Seedance prompts from the docs read like shot lists: slow aerial push over a foggy mountain valley at sunrise; close-up rain on a city puddle with neon reflections; empty office interior with late-afternoon window light and a slow drift; product shot with subtle focus pull on a minimal desk. Each example names subject, camera, and light — the same discipline you would give a second unit.

Kling 3.0 Pro is for takes that matter — natural faces, hand interactions, walking talent, office scenes with bodies in frame. Kling 3.0 Standard is the fast pass: generate several framings, pick a winner, then run a Pro pass on the composition you trust.

Native audio on Kling 3.0 covers footsteps, room tone, and light effects so you are not always laying silence under human b-roll. For dialogue-heavy character moments the docs steer toward Veo 3.1; for sports and extreme motion, Hailuo 2.3 is the alternate called out in the model decision table.

Documented Kling prompts skew human and professional: talent walking a modern hallway with shallow depth of field; hands typing with coffee in soft focus; handshake in a bright meeting room; runner at dawn with cinematic motion blur. The pattern is recognizable situations with clear subject and lighting — not abstract "corporate vibe" language.

Iteration strategy matters: Standard for three to five quick framings, Pro for the take you will show the client. Generate more than you need and choose the best performance — AI variance is real, and editors who only keep the first render often mistake bad luck for bad tooling.

While cutting, name what is missing: wide or close, mood, whether people appear. People in frame → Kling 3.0 Pro. No people → Seedance 2. Optional: park the playhead on a shot that already has the right grade and hit Frame Capture so the model inherits color temperature and composition.

Structure prompts as subject + camera + light + style. Example shape: aerial drift over a coastal town at golden hour, gentle movement, warm evening light, cinematic. Generate into Library, audition takes in-panel, drag the keeper to the timeline. If the first pass is close but not right, tweak one variable and regenerate — the loop is designed to stay under a couple of minutes.

• Transition Mode — start and end frames from the timeline, Seedance 2 or Kling O3 Transition fills the bridge
• Kling O3 Multi-Cam — new angles from footage you already shot
• Reference Mode — consistent product or character across a batch of b-roll clips

Beyond single clips, Reference Mode keeps characters or products consistent across a series — Kling O3 Reference for up to seven images, Seedance 2 Reference for up to nine images plus audio references when sonic environment should match. Transition Mode bridges two frames you mark on the timeline; Multi-Cam generates new angles from footage you already have. Those modes turn b-roll from one-off rescue into a repeatable show look.

Audio tip from the workflow doc: on environment shots, try Seedance ambient before replacing everything in the mix — wind, city hum, and rain are often usable with light level rides.
