DaVinci Resolve features a context-sensitive smart trim tool that automatically switches between Roll, Ripple, Slip, and Slide trimming based on where you position the cursor on a clip in the timeline. You select the trim mode once, and the tool changes behavior depending on whether you hover near the edge, the center, or between clips. This eliminates the need to manually switch between trim tools as you work. The smart trim tool is activated by clicking the trim icon in the toolbar or pressing the T key. Once in trim mode, move your cursor over the timeline and watch it change icons based on position. The cursor tells you which trim type will be applied before you click. ## What are the four trim types in DaVinci Resolve? ### Roll Trim A roll trim works on both sides of an edit point simultaneously. When you drag the edit point, one clip is shortened while the adjacent clip is extended by the same number of frames. The overall timeline duration remains unchanged. ![Roll Trim](https://images.blackmagicdesign.com/images/products/davinciresolve/edit/trim/roll@2x.jpg?_v=1642653016) Use roll trimming when you want to adjust the transition point between two clips without changing the total timeline length. If your dialogue scene is perfectly timed but the cut between two speakers feels off, a roll trim shifts the cut point earlier or later without affecting anything else. ### Ripple Trim Ripple trimming extends or shortens the beginning or end of a single clip. When you ripple an edit point, everything to the right of the edit is pushed down the timeline or pulled in to accommodate the clip's new duration. ![Ripple Trim](https://images.blackmagicdesign.com/images/products/davinciresolve/edit/trim/ripple@2x.jpg?_v=1642653235) Ripple trimming is the most commonly used trim type. Use it to shorten a clip that goes on too long or extend a clip that ends too soon. The ripple effect ensures there are no gaps in the timeline — all subsequent clips shift to maintain a continuous sequence. ### Slip Trim Slipping changes the portion of a clip visible on the timeline by moving its in and out points together. The clip duration remains the same, but the content shifts earlier or later within the clip. A white outline in the viewer shows the full source clip duration and your current position within it. ![Slip Trim](https://images.blackmagicdesign.com/images/products/davinciresolve/edit/trim/slip@2x.jpg?_v=1642653018) Use slip trimming when the clip duration is correct but you want to show different content within that duration. For example, if a talking-head clip is the right length but you want the speaker to start on a different word, slip the clip forward or backward without changing its position on the timeline. ### Slide Trim Sliding changes a clip's position on the timeline without changing its length. The clips on the left and right get shorter or longer as you slide the middle clip. Think of a slide as a roll trim between three clips — the middle clip moves while the adjacent clips adjust to accommodate it. ![Slide Trim](https://images.blackmagicdesign.com/images/products/davinciresolve/edit/trim/slide@2x.jpg?_v=1642653017) Use slide trimming to reposition a clip within a sequence while preserving the total timeline duration. If a B-roll clip needs to appear a few seconds earlier in the sequence, slide it left and the surrounding clips adjust automatically. ## When should you use each trim type? | Trim type | What changes | Timeline duration | Best for | |---|---|---|---| | Roll | Both sides of an edit point | Unchanged | Adjusting cut points between clips | | Ripple | One edge of one clip | Changes | Shortening or extending clips | | Slip | Content within one clip | Unchanged | Changing visible content without moving the clip | | Slide | Position of one clip | Unchanged | Repositioning clips in a sequence | The smart trim tool detects which trim type to use based on cursor position. Hover near the edge of a clip for Ripple trim. Hover exactly on the edit point between two clips for Roll trim. Hold Cmd/Ctrl and hover near the center for Slip trim. Hold Cmd/Ctrl and hover near the edge for Slide trim. ## Can you trim during playback in DaVinci Resolve? Yes. You can trim while the timeline is playing, which lets you hear the exact moment a cut should happen. In trim mode, click and hold the edit point you want to adjust, then listen as you drag. The audio plays in real time, and you can release the mouse when the cut sounds correct. This is significantly faster than stopping playback, trimming, and playing again to check. For dialogue editing, trimming during playback is essential for achieving natural pacing. For music videos, it lets you align cuts to beats while hearing the track.

## How do you trim multiple tracks at the same time in Resolve? Hold Shift while trimming to apply the trim to the same edit point across all linked tracks. If you have video on V1, dialogue on A1, and music on A2, a Shift-trim adjusts all three simultaneously, maintaining sync between the tracks. For more selective multi-track trimming, lock the tracks you do not want to adjust by clicking the lock icon in the track header. Only unlocked tracks are affected by the trim operation. ## FAQ ### How do I activate the smart trim tool in DaVinci Resolve? Click the trim icon in the toolbar (looks like a pair of arrows pointing away from each other) or press the T key to enter trim mode. ### Can I switch between trim types manually without the smart cursor? Yes. You can select individual trim tools from the toolbar dropdown if you prefer to work with explicit tool selection rather than context-sensitive switching. ### Does slip trimming work with clips that have speed changes? Yes. Slip trimming changes the source frame range without affecting the speed change applied to the clip. ### Can I trim using keyboard shortcuts instead of the mouse? Yes. Use the trim keyboard shortcuts — typically , and . for frame-by-frame adjustments, Shift+, and Shift+. for larger increments. ### What happens if I try to slip a clip that has no additional source footage? The slip trim reaches its limit when the in point reaches the start of the source clip or the out point reaches the end. The cursor indicates when you have reached the limit.
