Video editing and post-production

Extra editing hands for producers, agencies, brand teams and post houses. We fix your social video ads, then version and localise them.

One ad. Every screen shape.

From one master to every social size.

The difference

Fixed, not just flagged.

Most QC sends you a list of problems.
We send back fixed files.

Typical QC

  • Tells you what’s wrong
  • Leaves the fixing to your team
  • Back and forth until it’s right
Result: a list of problems

Passix

  • Fixes what’s wrong
  • No extra work for your team
  • Delivered back passed, fixed and ready to go
Result: a file that passes

What we do

Extra hands when yours are full. Three things, done properly.

Passix is a UK post-production overflow studio. When your team is full, we edit your video ads, make every social size, check them against each platform’s rules and fix what we find. For producers, agencies, in-house brand teams and post houses.

No project files needed. Just a clean and texted master.

Editing and multi-format versioning

Your finished edit (the master), reframed and versioned for every social size, from widescreen to phone, with the copy you supply.

Social QC that fixes

Quality checks against each platform’s rules, such as sizes, captions and sound levels.

Overflow capacity

Working alongside your usual team or post house when they’re booked up and the deadline hasn’t moved.

Why Passix

Six reasons to pass it here. Custom automation, a human at the helm.

01

Fixed, not just flagged

No report to decode. Just fixed files.

02

Every size from one master

No project files needed. Just a clean and texted master.

03

Localised for every market

Built from the translated text you supply.

04

Issues sorted before work starts

Six questions up front, so nothing surprises you later.

05

Faster turnaround, built on custom automation

Our own tools take out the repetition. A person checks every frame.

06

Extra capacity when you need it

For the jobs your team can’t fit in.

The Passix promise

A pass,
or you don’t pay.

In scope, in writing, and with any blocking issues named early.

Social deliverables only. Terms apply.

Who we work with

Built for teams that are already busy.

Producers

Tight deadlines and no time for another round.

Agencies

Many versions to deliver, or small jobs not worth a suite booking.

In-house brand teams

More work than people this month.

Post houses

Overflow when the suite is booked.

Questions

Versioning means taking one finished master ad and turning it into every size, length and language you need, each one checked and ready to post.

Passix is a UK post-production overflow studio. We take on editing and multi-format versioning, social QC that fixes what it finds, and overflow capacity for producers, agencies, in-house brand teams and post houses when their own team is full.

Producers, agencies, in-house brand teams and post houses. Producers with tight deadlines and no time for another round. Agencies with many versions to deliver, or small jobs not worth a suite booking. In-house brand teams with more work than people this month. Post houses that need overflow when the suite is booked.

Every social size: 16:9, 1:1, 4:5, 2:3 and 9:16. We reframe and version your finished edit (the master) for each size, with the copy you supply.

No. Send them if you have them, and we’ll use them. If you only have a master, that’s fine too. We’ll ask a few questions first so we know what we’re working with.

Quality checks against each platform’s rules, such as sizes, captions and sound levels. Typical QC tells you what’s wrong and leaves the fixing to your team. We fix what we find, so files are delivered back passed, fixed and ready to go. Already have a QC report? We’ll work through the fixes.

No, you supply the translation. We build each localised version from it and make sure every one fits and passes.

A pass, or you don’t pay. In scope, in writing, and with any blocking issues named early. Social deliverables only. Terms apply.

Who we are

Passix Ltd is registered in England and Wales, company no. 17540411. We decide how the personal information described here is used, so we are its controller. You can reach us at bookings@passix.co.uk.

What we collect

When you send us a brief through the form, we get what you type in: your name, your email address, your company, what you need, your deadline, details of the project and any link to files. If you email us or send us files, we get those too.

Why we use it

Only to reply to you and to do the work you ask for. Our lawful basis is taking steps you ask for before a contract, and our legitimate interest in answering enquiries about our work. We don’t send marketing and we never sell your information.

Who we share it with

Only the service providers that run this site, its form and our email: Netlify hosts the site and receives form submissions, and Proton runs our email. They handle it on our behalf. This site also loads its fonts from Google Fonts, so your browser shares your IP address with Google when a page loads.

How long we keep it

No longer than we need it: up to 2 years after we were last in touch, unless we are working together, in which case we keep project records for as long as the work and our legal obligations need.

Cookies
