What you get
Proofing tools that keep up.
Frame-accurate markup
Draw and comment on the exact frame or time range. Every annotation stays pinned to the moment it's about.
Version comparison
Stack two versions and scrub them in sync across five modes, including Pixel Diff for tiny changes.
Approval trail
Track status from In-Progress to Approved, resolve comments, and lock the final with a permanent log.
No account for reviewers
Stakeholders open a link and proof in the browser. No signup, no app, and they're free on every plan.
Mark up the exact frame.
Draw, type, or record a voice comment on the precise frame. No vague comments, no scrubbing to find what a reviewer meant.
Compare every version.
Split, Wipe, Overlay, A/B, and Pixel Diff with synced scrubbing. Prove that each round of comments actually landed.
Locked approvals on record.
Lock the approved version and keep the full version history. There's never a question about which version got signed off.
How it works
How proofing works in Dusken.
From first markup to a locked, approved final.
Upload the proof
Drop your video or image into a Folder. Voice comments are transcribed so feedback is searchable.
Collect markup
Reviewers draw and comment on the exact frame. Threads keep each comment organized with a resolved status.
Prove the changes landed
Use Pixel Diff and Split to show stakeholders that every comment made it into the new version.
Approve and archive
Lock the approved version. Dusken keeps a clear trail of who approved what.
The shift
What changes with Dusken.
Screenshots marked up in another app, approvals buried in an email thread, and no clear record of the final version.
Markup on the frame, version compare to confirm fixes, and a locked final with a permanent approval log.
| Capability | Traditional Process | With Dusken |
|---|---|---|
| Review & Approval Flow | Screenshots marked up in another app, approvals buried in an email thread, and no clear record of the final version. | Markup on the frame, version compare to confirm fixes, and a locked final with a permanent approval log. |
| Stakeholder Access | Expensive per-seat licensing or account friction required to view drafts | Zero-login instant browser links, 100% free unlimited reviewers on every plan |
| Precision & Tools | Vague timestamp typing, miscommunicated edits and lost version history | Frame-pinned annotations, voice-note transcription, multi-mode version compare and NLE marker export |
“A reviewer used to write 'fix the thing near the start.' Now they pin the exact frame and leave a voice comment that lands already transcribed.”
Post-Production Lead
Why proofing is faster here.
Fewer rounds
Markup on the right frame plus version compare means reviewers and editors agree on what changed, the first time.
A clear record
Locked versions and approval logs protect the team. You always know which version was signed off, and by whom.
Reviewers are free
You pay for your team. Every stakeholder you add to a proof reviews free, so your bill doesn't move.
Questions before you start.
It's a tool for marking up video and getting it approved. Reviewers annotate the exact frame, you compare versions to confirm changes, and you lock the final. Dusken does all three with reviewers free and no login.
Yes. Stack two versions and scrub them in sync across five modes: Split, Wipe, Overlay, A/B, and Pixel Diff. Pixel Diff catches the small changes.
You approve it. Approving locks a version as the final one and keeps the full history, so there's no confusion about which version got signed off.
Both. Dusken proofs video and images with frame-accurate markup. Audio and PDF proofing are on the roadmap.
Neither. Reviewers are unlimited and free on every plan, and they review from a link with no account or app.
