Anyone can cut.
Deciding what to cut
is the job.

I watch the raw footage and the person in it, find the story that's already there, and pick a style that fits them.

Case studies

What it did

01
Liberty Funding · Jesse Tacoronte

He sells funding programs without ever filming himself.

Jesse needed video every week to sell his funding programs, but getting him on camera was the hard part. I built his AI avatar, so he keeps putting out video without a shoot.

Programs sold on video he never had to film.

02
BBDO · BMW Motorrad

BBDO put me on the BMW account for the motion work.

I was assigned to the BMW account specifically, handling After Effects and motion graphics; teasers, lifestyle content and key visuals for BMW Motorrad.

Chosen for the craft, on a global account.

03
Brands · UGC

UGC that's built to convert, not just to look good.

Ongoing short-form work for brands running creator campaigns. Hooks, pacing and cuts built around what each platform actually rewards, across skincare, supplements, property and SaaS.

Short-form made for performance, at volume.

How I work

When I get a brief, I don't wait for every detail to be spelled out. I look at the footage, figure out what the story is, and make the call on style and direction. Most of the time that's exactly what the client needs.

Services

What I Deliver

Long-Form Video Editing

Long YouTube edits, brand documentaries and campaign videos. Cut so people stay past the first minute.

Short-Form & Reels

Vertical video for Instagram, TikTok and Shorts. Fast cuts, hook up front.

Motion Graphics

Animated titles, transitions and graphics. The part that makes an edit look finished.

Content Systems

Ongoing content for brands that post every week. Same look across every piece, without the back and forth.

Paid Social Ads

Ad edits for Meta, TikTok and YouTube, cut in several versions with different hooks so you can test what sells.

Podcasts & Webinars into Shorts

Your long recordings, interviews and founder videos turned into a steady flow of clips for every platform.

About
Mia Greiff

Hi, I'm Mia

I'm a video editor in Argentina. I work with brands and creators around the world, turning raw footage into video people actually watch. I study English at the Facultad de Lenguas, so briefs, calls and scripts in English are no problem.

I've worked with global agency BBDO on visual content for BMW, and collaborated with U.S. agencies Branded Strong and Upperhand Creative, editing social media content, podcast clips, educational videos, and live performance coverage.

I trained in digital marketing at Coderhouse, so I edit with the goal in mind: what the hook has to do, where people drop off, and what makes them click.

I also helped develop Fayce, an AI video tool that clones a creator's face and voice from one recording.

5 years in. Premiere Pro, After Effects, Photoshop.
If you need content that's clean, fast, and on-brand, let's talk.
