How to Write AI VFX Prompts for Cleaning Up a Shot

Shot cleanup is the most common post-production VFX task — not dramatic explosions or sky replacements, but the unglamorous work of removing boom mics, cables, safety equipment, background pedestrians, and production artefacts from clips that would otherwise be unusable. This guide covers the multi-element cleanup prompt, where multiple things need to go at once.

The most important structure principle for cleanup prompts is: list removals first, then describe the preserve clause (what to keep), then describe the fill strategy (what should replace each removed element). This order gives the AI a clear priority: here's what to remove, here's what to protect, here's what to generate in the gaps.

For complex shots with many elements to clean, working in passes is more reliable than attempting everything in a single prompt. Remove the most prominent element first, confirm the result, then run subsequent passes. Each pass starts with a cleaner canvas.

What FXbuddy needs in a shot cleanup prompt

• Elements to remove: listed in order of priority — most prominent first
• Location for each: where in the frame each removal target is
• Preserve clause: explicit list of what must remain unchanged
• Fill strategy: what should replace each removed element
• Overall target: what the clean shot should look like at the end

Common mistakes

• No preserve clause: In multi-element cleanup, not specifying what to keep is dangerous — the AI may interpret "remove multiple things" as permission to simplify the entire scene. Always list the primary subject and any important elements as explicitly preserved.
• No fill strategy: "Remove these five things" without fill instructions means the AI makes arbitrary choices about what goes in each gap. Provide fill context for each removed element, even if brief: "fill with the wall surface," "fill with the street," "fill with the sky."
• Too many complex elements in one pass: Five simultaneous removals in complex zones (overlapping with subjects, varied backgrounds) often produces inconsistent results. Three or fewer elements per pass produces cleaner outputs on difficult shots.
• Vague location references: "Remove the thing in the background" when there are multiple things in the background gives the AI no targeting information. Be specific about each element: "the monitor stand in the background right."

Tips for better shot cleanup results

• The "clean version of this shot" framing can be useful as a summary statement at the end of a detailed removal list: "overall target is a clean, production-equipment-free version of this shot" helps the AI understand the intent when processing the specific removals.
• For documentary and run-and-gun footage, a common cleanup need is removing audio equipment (lavalier packs visible under clothing, cables visible on the waist). These are reliable removals when the surrounding clothing area is described clearly.
• When cleaning up a shot that will then receive VFX additions, generate the clean version first and verify it before adding effects. Building effects on top of a clean plate is always more efficient than trying to clean up a shot that already has VFX on it.
• For B-roll footage used in documentary or corporate content, a quick cleanup pass removing any visible production equipment or distracting background elements can significantly improve perceived production value with minimal effort.
• If you have a clean background plate (a shot of the location without any subjects or equipment), mention it in your prompt: "the clean background reference is available — fill all removed areas to match that environment." This gives the AI a reference target and produces more consistent fills.

Frequently asked questions

How many things can I remove in a single cleanup prompt?

You can list multiple removal targets in a single prompt, but the more complex the combined cleanup, the more variable the result. For shots with 2-3 distinct elements, combining them in one prompt often works well. For shots with 5+ elements, it's typically better to work in passes — most critical removal first, then subsequent passes for remaining elements.

What is the best order to approach a multi-element cleanup?

Start with the element that would be hardest to undo: large objects before small ones, foreground elements before background elements, objects that cross the main subject before objects in clear space. Once the most challenging element is cleanly removed, subsequent passes are easier because the AI has less competing information to process.

Can I clean up a shot and also make VFX additions in the same prompt?

You can, but the results are more controlled when you separate cleanup from creative additions. Run all removals first, confirm the clean output, then run any additive VFX on the cleaned clip. This two-stage approach prevents the AI from generating fills that conflict with your planned additions.

How do I handle a shot with both production equipment AND background pedestrians to remove?

Address both in one prompt, grouped by category: "remove all visible production equipment including the monitor stand in the background right and the cable visible along the left wall. also remove all background pedestrians. keep the main subject and all foreground elements unchanged. fill all removed areas with the appropriate background environment."
