Introduction

The library includes cinematic, ambient, electronic, lo-fi and jazz music. Filmstro also offers cinematic trailer sound effects and a bespoke music service.

What Filmstro offers

Filmstro offers three ways to work with its music: a desktop app for Mac, an extension for Premiere Pro and a web app in Google Chrome. Each uses the same music and Momentum, Depth and Power controls.

The music library includes tracks that can be shaped on a timeline. Filmstro also offers licences for uses including social media, games, podcasts, film festivals, streaming, TV and radio.

Brands named on the site

FILM RIOT action and horror scores are included with PRO or PRO PLUS licences.

Using the website

Filmstro offers a browser-based app in Google Chrome, with scoring sliders, a pen tool and real-time video preview. Tracks can be exported as WAV files.

The site also offers a handbook, a knowledge base and tutorial videos. An account dashboard and music and app-feature request options are available.

Notable features

Scoring controls: Momentum, Depth and Power can be moved in real time or drawn and keyframed on the timeline. In the desktop app, Momentum controls rhythmic drive, Depth controls harmonic colour and fullness, and Power controls weight and intensity.

Length and video sync: The desktop app can import video and match music to its length. Its Smart length feature uses intro, loop and ending sections to fit the length set.

Stems and MIDI: Desktop users can mute or solo instrument groups and see per-stem meters. A MIDI controller can be mapped to Momentum, Depth or Power.

Premiere Pro extension: The extension can take its music length from the in and out points in Premiere Pro. It also supports keyframes and stem controls, with offline editing once a track has been loaded.

Frequently asked questions
