Should I ask an AI video agent clarifying questions before generating, or just prompt it directly?

Let the invideo agent ask clarifying questions whenever a missing variable would change the output — character identity, duration, pacing, format, CTA, or how a shot should land. Prompt directly only when your brief already locks those. The questions cost seconds; a wrong generation costs credits.

Use this decision rule on every prompt: if your instruction leaves any of goal, audience, format, duration, character/product identity, or shot intent open, let the invideo agent ask before it generates — otherwise go direct. The invideo agent is an agentic video tool that holds project context across generations, so a 10-second clarification round upstream prevents a 4-second Seedance 2.0 clip rendering at the wrong pacing downstream.

When to let it ask first. Any time the gap between your words and a finished shot is wide: a new shot setup, a hook beat, a duration call, camera movement, or any creative decision you haven't locked. In one documented production, the invideo agent asked three things before generating a single clip — duration, speed, and how the shot should land — and the first generation came back usable. In another, the invideo agent pushed back on a requested 15-second edit and recommended 20 seconds based on existing brand ad benchmarks; that single clarifying exchange protected hook beats that a direct prompt would have compressed away.

When to prompt directly. When your brief already covers the variables. If you've locked cast, wardrobe, location, shot breakdown, and duration — or you're regenerating one shot inside an established setup — skip the dialogue and prompt. Repeat shots inside a locked setup inherit the look automatically, so a direct prompt is the right call there. The same holds for batched iterations: once the first shot of a setup is locked, the next four in that batch don't need a new Q&A round.

The minimum brief that earns a direct prompt. Goal, audience, format/aspect in your delivery spec, duration, character or product identity (with reference images if relevant), and shot intent (framing + camera move + how it lands). Missing any one of those — ask. A sharper brief up front makes the invideo agent more proactive on next steps throughout production; a vague brief invites guesswork that burns credits.

One habit to combine with both modes. When you do prompt directly, instruct the invideo agent to state its assumptions and play back its planned execution before generating — duration, camera move, transition, landing. You confirm or correct in text, then it generates. This Confirm-Before-Generate step is cheap (no credits spent) and catches the misreads that otherwise show up as a rejected 4-second clip. For shots where framing is genuinely uncertain, go further: ask for a still image first, lock the frame, then spend video credits — across documented productions, clip rejection ran around 85%, and image-first iteration is what kept per-ad cost near $125 instead of multiples of it.

The sitrep prompt — use it mid-project, not just at the start. Periodically ask the invideo agent for a sitrep: what's locked (cast, wardrobe, location, music, shot breakdown) and what's still open. This surfaces unresolved decisions before you waste a generation on them, and is the cleanest way to decide whether the next prompt should be a question round or a direct instruction.

Watch some of these to see what works for you:

The agent proactively, like a good AD, asked me three things before generating: the duration, the speed, and how it should actually land.
