EDL and OTIO

OpenRV Web supports exporting Edit Decision Lists (EDL) in CMX 3600 format and importing OpenTimelineIO (OTIO) editorial timelines. These features bridge OpenRV Web with editorial and conform workflows.

EDL Export (CMX 3600)

Export the current playlist as an EDL file. Two paths are available:

• Playlist panel -- click the EDL export button in the panel footer
• Export menu -- select "Export EDL (CMX 3600)" from the top-bar Export dropdown (the export uses the same playlist data)

Format

The exported EDL uses the CMX 3600 standard format:

TITLE: OpenRV Playlist
FCM: NON-DROP FRAME

001  SourceA  V     C        00:00:00:01 00:00:04:01 00:00:00:01 00:00:04:01
* FROM CLIP NAME: SourceA

002  SourceB  V     C        00:00:00:01 00:00:02:01 00:00:04:01 00:00:06:01
* FROM CLIP NAME: SourceB

Timecode

Timecodes use the SMPTE format (HH:MM:SS:FF) at the session frame rate (default 24 fps). Each entry includes:

• Source in/out -- the frame range within the source clip
• Record in/out -- the position in the output timeline

Drop Frame Support

The EDL writer supports drop-frame timecode for frame rates that require it (29.97 fps). Non-drop frame is the default.

How to Export

1. Open the Playlist panel (Shift+Alt+P)
2. Add clips to the playlist using "Add Current"
3. Configure in/out points for each clip
4. Click the EDL export button (download icon) in the panel footer
5. The EDL file downloads to the browser

OTIO Import

OpenTimelineIO (OTIO) files can be imported to reconstruct editorial timelines within OpenRV Web.

Supported OTIO Elements

Element	Support
Clips	Imported with source references and timeline positions
Gaps	Preserved as empty regions; gap spacing is reflected in playlist globalStartFrame values so that clips are not contiguous when gaps exist
Transitions	Parsed and stored as metadata (lastOTIOImportResult.transitions); wired to TransitionManager when available (visual crossfade rendering depends on the transition manager)
Markers	Imported from timeline, track, and clip levels; colors mapped to hex
Metadata	Preserved on each playlist clip (PlaylistClip.metadata) and on the import result (lastOTIOImportResult.metadata)

Import Process

1. Load an OTIO file using any of these methods:
   • File picker -- click the Open button in the top bar and select an .otio file
   • Drag and drop -- drop an .otio file onto the viewer
   • Playlist panel -- click the Import button in the panel footer and select an .otio file
2. OpenRV Web parses the timeline structure
3. Clips are mapped to available media sources

Conform / Re-link Panel

When OTIO clips reference media files that are not yet loaded, the Conform/Re-link panel appears (toggle with the link icon in the header bar). This panel allows:

• Viewing unresolved media references -- each clip shows its original filename, reason for failure, and suggested matches from already-loaded sources
• Per-clip browse -- click "Browse..." on any clip row to open a file picker, select a replacement file, and the clip is re-linked automatically
• Batch re-link by folder -- click "Re-link by Folder..." in the toolbar to select multiple files at once; unresolved clips are fuzzy-matched against the selected files by filename (score >= 80) and re-linked in bulk
• Auto Re-link -- click "Auto Re-link" to match unresolved clips against already-loaded sources by filename similarity
• Suggestions dropdown -- when loaded sources have similar names, a dropdown lets you pick a match manually

Once media is re-linked, the timeline plays back with the correct content at the specified frame ranges.

Pipeline Note

EDL export enables the editorial roundtrip: assemble a review playlist in OpenRV Web, export a CMX 3600 EDL, and import it into Avid, Premiere, or Resolve to conform the edit against the original media. OTIO import works in the opposite direction -- export a timeline from editorial and load it into OpenRV Web to review the cut with the VFX team. This closes the loop between editorial and VFX review.

VFX Use Case

When using OTIO import for conform, the Re-link panel is critical. VFX media often lives on different storage paths than editorial media. Use the "Browse..." button on individual clips or "Re-link by Folder..." to select multiple replacement files at once. The fuzzy filename matching will automatically pair unresolved clips with the best-matching files, so you can quickly re-link shots to your local VFX renders and review the edit in context with the latest comp versions.

Dailies Reports

The Report Exporter generates review session reports in CSV and HTML formats. Reports include:

Field	Description
Shot name	Clip or source identifier
Status	Per-source review status (pending, approved, needs-work, etc.)
Notes	Review notes and comments
Version info	Version number and history
Frame range	In/out points for each clip
Timecodes	SMPTE timecodes for each clip

Exporting Reports

Reports are available from the Export menu:

• CSV -- tabular data suitable for import into spreadsheets or production tracking tools
• HTML -- formatted report suitable for printing or sharing via email

Playlist Integration

EDL export and OTIO import are tightly integrated with the Playlist Manager. The playlist stores clips with source indices, in/out points, and global timeline positions. The EDL writer serializes this data, and the OTIO importer creates playlist entries from the imported timeline.
