Post-production tools · Built in a working studio

The tools our studio needed. Now built for yours.

Bring your studio NAS and cloud drives into one place, work on edit, grade and sound with anyone in the world in real time, and check every mix before it leaves the room. SunStack is built inside Sunrise Film, a working post-production studio.

The problem

Post-production still runs on workarounds.

  1. 01

    Files travel the hard way.

    NDA footage and sessions go out over FTP and transfer links. Nobody is sure who has what, and big files break on the way.

  2. 02

    The client has to be in the room.

    Or watch a compressed screen share where the mix sounds wrong and the picture stutters. Every remote session feels like a compromise.

  3. 03

    Mistakes slip through QC.

    Not every broadcaster, platform or distributor has its own QC. One missed defect — a click, a phase issue, dialogue doubled in the surrounds — and it ends up on screen.

The stack

Three tools. One studio workflow.

Each tool solves one daily problem. Today they work on their own; next, they come together in one workspace.

SunStreamIn development

Post-production, live, from anywhere.

Stream your edit, grade or mix session to anyone's browser in real time. They watch, listen, talk, draw on the frame and leave notes tied to the moment.

SunQCIn development

Audio QC that never gets tired.

Scans 5.1, stereo and mono mixes and stems for loudness, peaks, clicks, phase and channel errors — then takes you straight to each spot. You make the call.

One project, start to delivery

How it works in the studio.

  1. 01SunDrive

    Store & share

    Footage, sessions and references stay where they are — on the studio NAS or in the cloud — and the team reaches them in one place. Each person sees only what they need; a set of files goes out with one link.

  2. 02SunStream

    Work together

    The editor, colourist or mixer streams the session. The director joins from another city — from a laptop or a phone.

  3. 03SunStream

    Note the moment

    They talk, draw on the frame and leave notes tied to the exact time.

  4. 04SunStream

    Back into the timeline

    Notes come out as markers for REAPER and Nuendo — no retyping.

  5. 05SunQC

    Check before delivery

    The final mix and stems go through QC. Flagged spots land in the DAW as markers; compare old and new after the fix.

Why SunStack

Made by people who edit, grade and mix.

Born on real projects.

Every feature started as a problem on a Sunrise Film project — and gets tested there first.

Every drive, one set of rules.

SunDrive connects the studio NAS and cloud drives, with invite-only access and per-person permissions across all of them.

Nothing to install for clients.

A SunStream link opens in any modern browser — laptop, tablet or phone.

The machine finds. You decide.

SunQC flags what looks wrong; a human listens and confirms. No black-box verdicts.

Proof of work

Built inside a working studio.

Sunrise Film is a sound design and mixing studio for film and series, working from Warsaw and Kyiv. SunStack is how we fix our own bottlenecks — and then share the fix.
