What Can Really Be Fixed in Post? A VFX Clean-Up Guide for Ad Films

Every ad shoot leaves something behind that nobody wanted in the frame: a boom mic dipping into the top of the shot, a reflection of the crew in a car door, a logo the brand cannot show, a stray cable across the floor. "We'll fix it in post" is said on almost every set. This guide from Film by Him, a post-production and VFX studio, explains what clean-up can realistically fix, what it costs in time, and how to plan a shoot so the fixes stay quick.

The clean-up jobs that are usually quick

Rig and boom removal on static or slow shots, especially when there is a clean background plate.
Small logo and label removal on objects that do not move much.
Skin and beauty retouching for close-ups in beauty, fashion and lifestyle ads.
Screen replacements on phones, laptops and TVs, as long as the screen was shot with tracking markers or a plain colour.
Sky replacements on wide exteriors with clear edges.

The jobs that take longer than people expect

Removing objects that cross people, such as a cable behind moving hair or a stand behind someone's hands.
Reflections on curved, shiny surfaces like cars, bottles and glasses. The reflection moves with the camera and the product.
Fast handheld shots, where every frame needs tracking before anything can be painted out.
Changing the colour of a product across many shots, especially fabric that folds and catches light.

These are all possible, but they are frame-by-frame work. A few seconds of difficult clean-up can take longer than the rest of the edit.

How to make clean-up fast and cheap

Shoot a clean plate. After each setup, hold the camera still and record a few seconds with no actors, rigs or crew in the frame. This one habit saves more post time than anything else.
Lock off when you can. A tripod shot is far easier to clean than a handheld one.
Mark screens. Put small tracking markers on phone and laptop screens, or shoot them showing a flat green or grey.
Flag problem shots on set. A quick note in the camera report ("boom dips at the end of take 4") helps the editor and VFX team plan.
Bring a stills reference of the product, in the same light, for colour and logo fixes.

Fix it in post, or fix it on set?

A simple rule: if a fix on set takes less than five minutes, do it on set. Moving a light stand, taping a cable or wiping a reflective surface is almost always cheaper than removing it digitally. Save post-production for the things that cannot be controlled on the day, such as a passing car, weather, or a last-minute logo change.

Bringing it together

Clean-up is the invisible part of a polished ad film. Viewers never notice it, which is the point. Plan for it during the shoot, shoot clean plates, and give your VFX team clear notes, and "we'll fix it in post" becomes a quick, predictable step instead of an expensive surprise.
