On **Takes**, the picker at the top chooses what the column lists. ![The Takes tab of the Editor with the picker menu open. It shows a script name, All Takes, three lists with their counts, and New list.](https://mintcdn.com/lightcraft/wOgMVOSKOvh9lobi/images/spark/editor-list-picker.png?fit=max\&auto=format\&n=wOgMVOSKOvh9lobi\&q=85\&s=77fd4c629b634af4a965937ca1f7be85) 1. The menu is grouped by script. 2. **All Takes** lists every CG Take and take in that script. 3. A list from the Gallery, with the number of items it holds. 4. **New list…** creates a list. Click any row to load it in the clip viewer. ![The Editor with a take row highlighted in the left column, the take showing in the clip viewer, and its source values in the Inspector.](https://mintcdn.com/lightcraft/wOgMVOSKOvh9lobi/images/spark/editor-take-loaded.png?fit=max\&auto=format\&n=wOgMVOSKOvh9lobi\&q=85\&s=bff2ef3cf3f0c801755ff49102878b0c) 1. The row you clicked is highlighted. 2. The clip viewer names the kind of item: **CG Take**, **Take**, or **Audio**. 3. The Inspector shows the **Source** values: dimensions, frame rate, and duration. Audio shows only duration. ## Adding takes to the timeline Drag a row by its grip onto a timeline lane. You can also open the row's **…** menu. ![A take row's menu in the Editor with Add at playhead, Regenerate BG, Download, and Remove from this list. A plus button sits beside the picker.](https://mintcdn.com/lightcraft/wOgMVOSKOvh9lobi/images/spark/editor-take-row-menu.png?fit=max\&auto=format\&n=wOgMVOSKOvh9lobi\&q=85\&s=053ac94c5757a8b9af1aa80fb6c66e79) 1. **Add at playhead** puts the item on the timeline at the playhead. 2. **Remove from this list** takes the item out of the open list. The change also shows in the Gallery. 3. The **+** button adds CG Takes and takes to the open list. To put several takes on the timeline: 1. Drag a row by its grip onto a video lane and let go. 2. Click in the time ruler to move the playhead. 3. Open another row's **…** menu and click **Add at playhead**. The list in the Editor is the same list the Gallery shows. With the sort set to **Custom order**, drag a row up or down by its grip to reorder the list. The Gallery shows the new order too. ## Marking a stretch of a take You do not have to put a whole take on the timeline. Mark the stretch you want first. 1. In the Editor, click a take or a CG Take in the left column. It loads in the **Clip** pane, to the left of **Program**. 2. Play or scrub to the first frame you want and press **I**. The button is **Mark in**. 3. Go to the last frame you want and press **O**. The button is **Mark out, including this frame**, so the frame you see is included. A band with a white edge at each end shades the marked stretch on the scrub bar. * Pressing **O** on a frame before the In mark clears the In mark. The band then runs from the start of the take to the new Out mark. * Press **Alt+X**, or click **Clear the marks**, to remove both marks. With no marks, that button's tooltip reads **No marks to clear**. ### Audio files An audio file is marked the same way, with **I** and **O**. Dragging a marked audio file to the timeline places only the marked stretch. While you drag, the ghost shows the marked length in seconds. ### Marks belong to one edit Marks are saved. After you reload the page, the band is still on that take. The same take in a different edit has no marks. ### When a timeline clip is selected While a clip on the timeline is selected, **Mark in** is greyed out. Its tooltip reads **A clip is trimmed on the timeline. Open its source from the name to mark it**. Press **F**, or click the clip's source name (tooltip **Open the source**), to load the full take in the **Clip** pane and mark it there. ## Inserting and overwriting Two keys put the marked stretch of a take on the timeline at the playhead. **Insert** (**V**) pushes later clips along. **Overwrite** (**B**) replaces what is under it. ### Where the clip goes One video lane header is tinted. **Insert** and **Overwrite** put the clip on that lane. It is the last video lane you clicked in. If that lane is locked, the tint moves to an unlocked video lane. ### Inserting 1. Load a take in the **Clip** pane and mark the stretch you want. See [marking a stretch of a take](#marking-a-stretch-of-a-take). 2. Move the timeline playhead to where the clip should start. 3. Press **V**. The button's tooltip reads **Insert at the playhead, pushing later clips on the lane along**. The marked stretch lands at the playhead. A clip under the playhead is split there, and every later clip on that lane moves right by the length of the new clip. The playhead jumps to the end of the new clip, and the **Clip** pane still shows the take, so you can press **V** again to lay clips back to back. For a marked audio file, **V** puts the marked stretch on an audio lane. ### Overwriting Press **B**. The button's tooltip reads **Overwrite at the playhead**. The marked stretch lands at the playhead and nothing moves. Clips under it are shortened or cut to make room, and the end of the lane stays where it was. ### Undoing One **Ctrl+Z** puts the lane back as it was, including a clip that was split. **Ctrl+Shift+Z** brings the insert back. ### When Insert and Overwrite are greyed out * While a timeline clip is selected, both buttons are greyed out with the tooltip **This clip is already on the timeline**. * If every video lane is locked, **V** shows **Every video lane is locked. Unlock one to insert.** and changes nothing. ## Choosing which video a clip plays A take can have several videos: **Comp**, **BG**, **Camera**, **Matte**, and **Depth**. 1. Load the take in the **Clip** pane. 2. Click the video button on the take's name line. 3. Choose a video from the menu. Videos the take does not have are greyed out. The **Clip** pane shows the video you chose. A clip you place on the timeline after that shows the video's name on a second line. Select the clip to see a **Video** section with the same choice in the Inspector. ## Audio Add and control audio tracks alongside your clips. The **Audio** tab is beside the **Takes** tab in the left column of the Editor. It lists the production's audio files. * To add a file, click **Upload** at the top of the tab. * To use a file, drag its row onto an audio lane, or open its **…** menu and click **Add at playhead**. ## Keyboard shortcuts Hover a button to see what it does. If the button has a keyboard shortcut, the tooltip shows the keys on the right. For example, the step back button in the clip viewer reads "Step back one frame" with the **←** key, and "Back one second" with **Shift** and **←**. The keys match your keyboard. On a Mac they show as ⌘, ⌥, ⇧, and ⌃. On Windows they show as Ctrl, Alt, and Shift. ### Editor keys | Action | Key | | - | - | | Mark in | **I** | | Mark out, including this frame | **O** | | Clear the marks | **Alt+X** | | Insert at the playhead | **V** | | Overwrite at the playhead | **B** | | Open the source of the selected clip | **F** | | Split the selected clip | **Ctrl+K** (**⌘K** on a Mac) | | Trim the start of the selected clip to the playhead | **Q** | | Trim the end of the selected clip to the playhead | **W** | | Previous or next item in the left column | **Up** and **Down** | ## Export Export the edit as an MP4 with a chosen aspect ratio, resolution, and frame rate. > [!NOTE] > > Edits operate on rendered MP4 clips. You cannot dive from an edit back into the live 3D scene, and there is no EDL export. ## What edits are for Use the editing tab to see the story come together quickly, produce a rough cut for review, or prepare footage to hand off to an external editing or AI pipeline.
