AI Slate ID in DaVinci Resolve 21 automatically detects the clapperboard or smart slate in every clip and extracts the metadata written on it — scene number, take number, roll, date, and other production details — saving hours of manual metadata entry. It works even in dark, distant, or out-of-focus clips where the slate information would be difficult for a human to read. ![AI Slate ID](https://images.blackmagicdesign.com/images/products/davinciresolve/whatsnew/ai/slate@2x.jpg?_v=1775106164) The feature uses DaVinci Resolve's Neural Engine to analyze each clip, locate the slate within the frame, and apply optical character recognition to read the written information. It processes the slate data during media analysis and populates the corresponding metadata fields in the Media Pool automatically. For narrative film and commercial production, this eliminates one of the most tedious tasks in the dailies workflow. ## How do you use AI Slate ID in DaVinci Resolve 21? AI Slate ID runs automatically during media analysis. When you import clips that contain clapperboards, Resolve 21 detects the slates and processes them in the background. The extracted metadata appears in the Media Pool columns for Scene, Take, Shot/Take, and Roll. To review the extracted metadata, open the Media Pool and ensure the relevant columns are visible. Right-click on the column header and select Scene, Take, and Roll if they are not already displayed. Each clip that contained a readable slate will have its metadata populated automatically. You can also trigger Slate ID manually on specific clips. Select a clip in the Media Pool, right-click, and choose "Analyze Slate" from the context menu. This is useful for clips that were imported before you enabled automatic analysis or for clips where the initial detection did not produce clean results. The accuracy of the extraction depends on the visibility of the slate in the frame. Clips where the slate is clearly visible, well-lit, and positioned in the center of the frame produce the best results. The AI is designed to handle challenging conditions — dark scenes, distant slates, and partially obscured information — but accuracy decreases as visibility decreases. ## How does AI Slate ID handle smart slates and timecode? AI Slate ID can read both traditional clapperboards with handwritten information and digital smart slates that display timecode, scene, and take information on an LCD screen. For smart slates, the tool extracts both the visually displayed metadata and the timecode information when it is visible in the frame. The timecode extraction is particularly valuable for multi-camera shoots. When multiple cameras capture the same scene, each camera's footage includes the slate with matching timecode. Slate ID reads the timecode from each clip, and Resolve can use this information to synchronize clips from different cameras in the timeline. The tool does not read audio timecode from the clapper's audio track. The slate detection is purely visual. For audio-based sync, Resolve's existing auto-sync features using waveform matching are the appropriate tool. Slate ID complements these tools by providing the visual metadata layer. ## What is the complete dailies workflow with AI Slate ID? For narrative film and commercial productions, AI Slate ID fits into the broader dailies pipeline. The typical workflow looks like this: 1. **Ingest media**: Import your camera originals into DaVinci Resolve 21. This can be ARRI RAW, RED R3D, Blackmagic RAW, or any supported format. 2. **Run Slate ID**: Resolve automatically detects slates in the media pool and extracts scene, take, and roll metadata. 3. **Organize bins**: Use the extracted metadata to automatically organize clips into bins by scene or take. Smart Bins can be configured to group clips based on scene number, making navigation instant. 4. **Select takes**: Review the metadata to identify the best takes for each scene without manually logging every clip. 5. **Sync audio**: Use Resolve's auto-sync to synchronize external audio with the video clips, using the timecode or waveform. 6. **Edit**: Build your timeline with clips that already have complete metadata, making it easy to identify sources during the edit. For productions that use Cutsio upstream in the dailies pipeline, the workflow extends further. Upload native camera files — ARRI RAW (.ari, .mxf, .arx) or RED R3D — to Cutsio as an enterprise add-on. Cutsio transcodes the originals into streamable review assets, indexes every frame with Visual Intelligence, and keeps the original camera files attached for download. Your team reviews selects in Cutsio, exports an EDL with proper clip name mapping for Resolve relink, and when the timeline lands in Resolve 21, Slate ID reads the metadata from the original raw files automatically.

## How does AI Slate ID compare to manual metadata entry? | Method | Time per 100 clips | Accuracy | Consistency | |---|---|---|---| | Manual entry | 2-4 hours | Human error-prone | Varies by operator | | AI Slate ID | Automatic (seconds) | High in good conditions | Consistent | | Smart slate metadata | Automatic (from file) | Highest | Perfect | Manual metadata entry for a feature film with 500+ clips can take an entire day. AI Slate ID reduces this to the time it takes to import and analyze the media. The trade-off is that the AI may misread damaged, dirty, or partially obscured slates. Most productions find that reviewing and correcting a small percentage of clips is significantly faster than entering all metadata manually. ## How do you fix Slate ID errors in DaVinci Resolve 21? When Slate ID misreads a slate, you can correct the metadata manually. Select the clip in the Media Pool and edit the Scene, Take, or Roll fields directly in the metadata columns. You can also use the Metadata panel on the right side of the Media page to view and edit all metadata fields for the selected clip. For clips where the slate was not detected at all, you can trigger a re-analysis. Right-click the clip and select "Analyze Slate." If the slate is still not detected, the clip may have the slate positioned too far from the camera, in extreme shadow, or at an angle that the AI cannot read. In these cases, manual entry is required. Batch corrections can be applied using Resolve's metadata editing tools. Select multiple clips, edit the metadata field, and the change applies to all selected clips. This is useful for correcting consistent errors, such as a misread roll number across an entire shoot day. ## FAQ ### Does AI Slate ID work with the free version of DaVinci Resolve 21? No. AI Slate ID requires DaVinci Resolve 21 Studio. The Neural Engine features necessary for slate detection are not available in the free version. ### Can Slate ID read handwritten slates? Yes. The AI reads handwritten information from traditional clapperboards using optical character recognition. Accuracy depends on handwriting legibility and lighting conditions. ### Does Slate ID extract timecode from the slate? Yes, when the slate displays timecode visually (as on a smart slate), Slate ID reads it. It does not extract timecode from audio tracks. ### Can I export Slate ID metadata to other applications? The metadata is stored in DaVinci Resolve's project file. You can export it using Resolve's project export features or through third-party metadata management tools that integrate with Resolve. ### How long does Slate ID analysis take per clip? Analysis time depends on clip duration and complexity. Most clips process in a few seconds during the background media analysis phase.
