Proxy Media

Start cutting the moment footage lands — Sequence builds an optimized, browser-ready version of every clip in the background while the full-resolution file keeps transferring.

Every editor knows the wait. Dailies land, and before anyone can cut, the footage has to be transcoded to a mezzanine or a proxy, checked, and relinked. The assistant babysits a transcode queue while the editor sits idle. On a distributed team, that wait multiplies across every drive and every location.

Sequence removes the wait. When you add a file to a project, Sequence keeps two versions of it and tracks each separately: the Original Media, preserved at full quality for finishing, and an Optimized Media version it generates for fast, reliable playback in the browser. Optimizing runs as a background job right after the upload finishes, so a clip can play from its original for a moment before the optimized version is ready — and you keep editing the whole time. No online/offline juggling, no manual proxy pass, no relink step.

What you get#

Cut while it processes

  • Optimized Media generates automatically after upload
  • No preprocessing pass before you can start
  • Full-resolution Original Media is preserved for finishing
  • The whole team works from the same optimized versions

Playback built for the browser

  • Optimized versions are tuned for streaming and scrubbing
  • Responsive playback whether footage is local or remote
  • Lighter bandwidth than pulling full-res on every scrub
  • Consistent for everyone in the project, in any city

Runs in the background

  • Media processing is a server-side background job
  • A job is ready the moment it finishes, watched or not
  • Track it in the progress queue under Media Processing
  • Cancel or retry from the queue if you need to

Status you can see

  • Each asset shows an Optimized Media indicator with a status dot
  • See at a glance whether a clip's optimized version is ready
  • Check container, codec, and resolution in the Asset Metadata panel
  • No guessing which version you're playing

How it fits your pipeline#

Optimized Media exists so you can start immediately; Original Media exists so finishing gets the real thing. That split is what makes a cloud editor safe for professional work — you cut against a responsive proxy, and the full-quality source is always there underneath.

For the fastest path in, pair proxy media with Shuttle, Sequence's desktop companion for macOS. Shuttle mounts a project as a local drive in Finder and moves large volumes of footage in and out faster and more reliably than the browser — it starts uploading the moment you copy a file onto the mounted drive, and it prioritizes what you're actively watching over background transfers so playback stays smooth. Drop a reel onto the drive, and you can be cutting from optimized media while the full-resolution files are still on their way up.

Who it's for#

  • Assistant editors prepping dailies who want footage cuttable on arrival, not after an overnight transcode.
  • Editors on high-resolution or camera-original footage who need responsive scrubbing without a manual proxy workflow.
  • Distributed teams where every collaborator needs smooth playback of the same media from a different location.
  • Post supervisors standardizing ingest so nobody waits on transcodes to start work.
