Post-production tools · Built in a working studio
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
NDA footage and sessions go out over FTP and transfer links. Nobody is sure who has what, and big files break on the way.
Or watch a compressed screen share where the mix sounds wrong and the picture stutters. Every remote session feels like a compromise.
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
Each tool solves one daily problem. Today they work on their own; next, they come together in one workspace.

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.

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.

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.
The editor, colourist or mixer streams the session. The director joins from another city — from a laptop or a phone.
They talk, draw on the frame and leave notes tied to the exact time.
Notes come out as markers for REAPER and Nuendo — no retyping.
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
Every feature started as a problem on a Sunrise Film project — and gets tested there first.
SunDrive connects the studio NAS and cloud drives, with invite-only access and per-person permissions across all of them.
A SunStream link opens in any modern browser — laptop, tablet or phone.
SunQC flags what looks wrong; a human listens and confirms. No black-box verdicts.
Proof of work
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.
Coming next
Notes and corrections arrive in each tool first. Then Drive, Stream and a task manager meet in one place — and every note lives with the project it belongs to.
