One-click cover
Park the playhead on the frame you want, click the slot once, and LmBox Bridge grabs the current Program Monitor picture, imports it into the project, and lays exactly 2 frames of cover over the start of the timeline. Placement uses overwrite / append, so it does not ripple later clips forward. After success, the playhead returns to the start of the timeline.
What you will learn
- Drag "One-click cover" into an empty Toolkit slot
- Connect the editing extension, then drop a cover in one click in Premiere (CEP / UXP) or DaVinci Resolve
- Read tips such as "Open a timeline first" and "Could not grab the current frame"
Where to find it
- Open in the sidebar
- Drag One-click cover into an empty slot
- Click the slot in the main window or on the floating toolbar: it runs at once (no extra settings panel)
Connect the editing extension first. It works with Premiere CEP, Premiere UXP and DaVinci Resolve. After Effects, Final Cut and similar hosts currently show "Not available in this editor".
What it does
| Step | Description |
|---|---|
| Capture | Grabs the current frame of the active sequence / timeline from the Program Monitor (in DaVinci Resolve it briefly switches to the Edit page first, so a Color page grab does not capture only one clip) |
| Import | Writes the still into the local cache folder, then imports it into the project bin / media pool |
| Place | Lays 2 frames over the start of the timeline; prefers an empty track above V1, or creates a new video track; never places on V1 |
| No ripple | Premiere uses overwrite edit; DaVinci Resolve appends at the timeline start frame; neither pushes existing clips |
| Finish | Footer says "Cover placed at the start"; playhead returns to the start |
Common failures
| Footer tip | Meaning |
|---|---|
| Connect the editing extension first | Target extension is not connected |
| Not available in this editor | Connected, but not Premiere / DaVinci Resolve |
| Open a timeline first | No active project or no active sequence / timeline (needSeq) |
| Could not grab the current frame | Still export failed or the file was not written (needFrame) |
| Could not place the cover | Import or placement failed, or another error |
Notes
- Cover duration is fixed at 2 frames, converted from the current sequence frame rate; you cannot change it in the UI.
- You need an active timeline that can be captured; an empty project or no open sequence hits "Open a timeline first".
- If DaVinci Resolve is not on the Edit page, it switches briefly to capture, then tries to return to the previous page.
- Some Premiere versions also try to set the sequence poster frame; if that API is missing, it is skipped and placement is unaffected.
