Video Editing & Post-Production in London

From AI-enhanced editing to synthetic voiceovers and generative visuals, we help brands unlock a new layer of speed and scale, without compromising quality.

Pre-production planning, scripts and storyboards for a brand video

Overview

Footage on a hard drive isn’t a video. It’s potential. Post-production is where that potential gets shaped into something that holds attention, lands the message, and actually performs.

We handle the full post-production pipeline: editing, colour grading, sound design, mix, motion graphics, VFX, and final delivery. Every stage led by experienced editors and finishers who treat the edit as a creative job, not just an assembly line.

A strong edit can save a weak shoot. A weak edit can ruin a perfect one. The difference shows up in pacing, rhythm, music choice, frame timing, and the hundred small decisions that most viewers feel without ever consciously noticing.

We’ve been finishing commercials, brand films, and branded content for over a decade. The process is structured, the feedback loop is clean, and the final cut leaves looking like premium work, because that’s the only standard worth delivering.

 

Who this is for

For brands sitting on footage that isn’t working yet, and for teams who shoot in-house and need a finishing partner.

  • Brands and agencies that need a full edit pipeline, not just a cutter
  • Marketing teams handing over raw footage and expecting broadcast-ready output
  • Production companies looking for a freelance editor, colourist, or post supervisor
  • Founders and creative leads who care about how the final cut feels, not just what it shows
  • Teams that already shot the project and need post handled by people who’ll finish it properly

What we offer

Our AI marketing services help businesses create professional content without the high costs of traditional production. Using advanced AI technology, we deliver fast, scalable, and visually engaging content tailored to your brand and marketing goals.

Editing

tory-led editing built around pacing, rhythm, and message. We cut for retention, emotion, and clarity, across commercials, brand films, social content, and long-form narrative work.

Colour Grading

Professional grade work in DaVinci Resolve. Match the look to the brand, the mood, and the platform. Cinematic, commercial, premium product, lifestyle, graded properly so the footage stops feeling raw and starts feeling finished.

Sound Design

Dialogue cleanup, sound effects, foley, atmosphere, and full audio mix. Music selection, licensing, and integration. Sound is half the experience. We mix to broadcast-ready standards, not “good enough for social”.

Motion Graphics

Brand graphics, lower thirds, titles, logo animations, and on-screen text. Designed and animated to match your identity, not pulled from a template library.

VFX & Compositing

Clean-up, sky replacements, screen replacements, object removal, rotoscoping, and creative compositing. The fixes nobody sees and the effects everyone notices.

Subtitles & Versioning

Captions, subtitles, multi-language versions, and platform-specific cutdowns. One master film, every version your campaign actually needs.

The Process

01

Ingest

Footage backed up, transcoded, and organised. Sound synced, takes labelled, project structured properly. The groundwork that makes the edit faster and cleaner.

02

Rough Cut

Story shape locked first. Structure, pacing, message, and timing built before any polish. You see the rough cut early, give feedback, and we shape it together before moving forward.

03

Fine Cut

Edit refined to frame-level detail. Colour grade, sound design, mix, motion graphics, and VFX brought in. Every layer handled by the right specialist, not rushed by one person doing everything.

04

Delivery

Final master signed off. Platform versions, captions, and language cuts exported. Files delivered in the formats you actually need, ready to go live.

Frequently asked questions

What is post-production?

Post-production is everything that happens after the shoot. Editing, colour grading, sound design, mix, motion graphics, VFX, and final delivery. It’s the stage that turns raw footage into a finished, broadcast-ready video.

Do you only do post, or full production too?

Both. We can take on post-production as a standalone service when the footage is already shot, or run the full pipeline (pre-production, production, and post), depending on what the project needs.

Can you edit footage we already filmed ourselves?

Yes. A lot of our post work comes from clients who shot the project in-house, with another agency, or through a separate production team. Send the footage, the brief, and any reference, and we’ll take it from there.

How many rounds of revisions are included?

Two rounds of revisions are standard on most projects. We always recommend frontloading feedback at the rough cut stage, where structural changes are quick. By the time we’re at fine cut, big changes get expensive.

How long does post-production take?

Depends on the scope. A short social edit can turn around in a few days. A full commercial usually takes two to four weeks for proper editing, colour, sound, and finishing. Tight deadlines can be accommodated. We just plan around them.

Can you grade footage shot by another team?

Yes. We grade footage from any camera and any project. Send the original files (not transcoded social exports) and we’ll deliver a full professional grade in Resolve.

Do you handle sound mix and music licensing?

Yes. Full sound design, dialogue cleanup, mix to broadcast standards, and music sourcing through licensed libraries or custom composition for premium projects.

What deliverables do you provide?

Yes, where the project allows. We’re set up to move fast when needed, but quality always sets the floor. We won’t compromise the final result to hit a deadline that wasn’t realistic to begin with.

Can you handle urgent turnarounds?

It’s easy! Just reach out through our contact form or email, and we’ll schedule a free consultation to discuss your project and provide a detailed quote.
