Export Video Comments To DaVinci Resolve-Compatible Timeline Format (PROMPT)

[PraiseXI]

Problem

The marketing site currently says lawn supports exporting frame-accurate comments back into an editor workflow:

• app/routes/-for-video-editors.tsx

It includes copy like:

• “Export frame-accurate comments with timecodes and bring them straight back to Premiere, Resolve, or Final Cut.”
• “You see every note with precise timecodes, ready to export back to your NLE timeline.”

After inspecting the repo, I could not find an implemented comment export feature behind that claim.

Current State

These parts exist today:

• Comment schema in convex/schema.ts
• Comment queries/mutations in convex/comments.ts
• Dashboard video page UI in app/routes/dashboard/-video.tsx
• Share/watch pages in app/routes/-share.tsx and app/routes/-watch.tsx
• Video player and markers in src/components/video-player/VideoPlayer.tsx

What exists:

• Comments are stored with fields like text, timestampSeconds, userName, resolved, and optional parentId
• Comments render in the dashboard/share/watch experiences
• Video download exists

What does not appear to exist:

• No Export comments button
• No export endpoint/action for comments
• No Resolve-compatible export format
• No verified path to bring comments directly into DaVinci Resolve

Goal

Implement a real comment export workflow that lets a user download comments from a video and import them into DaVinci Resolve
in a way that is actually useful in editing.

The key requirement is not “download some text.” The requirement is “export comments in a Resolve-compatible format or workflow
that has been verified to import cleanly.”

Requirements

• Add an Export comments action on the dashboard video page
• Export only comments for videos the current user is authorized to access
• Preserve existing auth and access control patterns
• Include precise timing derived from timestampSeconds
• Include top-level comments and replies in a sensible flattened structure
• Include commenter name
• Include resolved state
• Keep the default UX simple and fast
• Avoid adding a public export hole
• Avoid introducing unnecessary loading waterfalls or blocking states

Resolve Compatibility

The output should be designed for DaVinci Resolve first, not as a generic spreadsheet export.

• The primary acceptance criterion is that the exported file can be imported into DaVinci Resolve as timeline markers or
  another clearly usable editorial format
• If a specific export format is chosen, document why that format is the right choice for Resolve
• Verify the workflow manually and document the import steps briefly in the PR or issue follow-up
• If a fallback export is also added, that is fine, but the main feature should still target Resolve compatibility

Suggested Implementation Direction

• Reuse existing protected comment/video access patterns in Convex
• Generate the export server-side so authorization remains centralized
• Return a downloadable file or signed URL the frontend can trigger immediately
• Add the button near the existing video actions on app/routes/dashboard/-video.tsx
• Use a stable filename such as <video-title>-comments.<ext>
• Keep the implementation structured so other export targets can be added later

Export Data Expectations

At minimum, the export should preserve:

• comment id
• parent comment id if present
• comment type such as top-level or reply
• author name
• comment text
• resolved state
• raw timestampSeconds
• human-readable time value
• ordering that is predictable and editor-friendly

Recommended ordering:

• top-level comments sorted by timestamp
• replies sorted by creation time under their parent

Acceptance Criteria

• A signed-in user with access to a video can click Export comments
• The export downloads successfully from the dashboard video page
• The exported file contains that video’s comments with accurate timing
• The resulting file can be imported into DaVinci Resolve in a documented, verified workflow
• Users without access cannot export comments
• The implementation does not weaken existing auth boundaries
• The feature is fast enough to feel immediate for normal review workloads
• The marketing claim is no longer misleading because there is a real Resolve workflow behind it

Optional Follow-up

If the implementation is structured cleanly, leave room for future formats such as:

• Premiere-compatible export
• Final Cut-compatible export
• generic CSV fallback
• SRT
• other timeline/marker exchange formats
