Slice Strobe Resolume
The slice strobe in Resolume Arena is a high-energy VJ technique used to trigger rapid, flashing visual pulses within specific mapped areas of a stage design, rather than across the entire screen. By targeting individual "slices" created in the Advanced Output, VJs can create intricate, rhythmic patterns that sync with lighting fixtures and music, making it a staple for professional LED wall performances. Understanding Slice-Based Strobing
Unlike a standard strobe effect that affects the whole composition, a slice strobe leverages Resolume's mapping capabilities. Slices are parts of your composition that you've routed to specific areas of your output, such as different LED panels or geometric shapes on a stage.
Dynamic Mapping: You can strobe individual shapes like triangles, circles, or custom polygons.
Precision Control: VJs often use this to "mimic" lighting blinders by flashing white or colored pulses on specific panels of an LED wall.
Workflow Integration: Most slice-based effects require you to reveal the Slices tab (View > Show Slices) and drag your defined slices into the effect's parameters. Key Plugins and Tools
While you can manually create these effects using the built-in Strobe effect on specific layers, most VJs use dedicated Wire patches or plugins for more advanced behavior: SLICE STROBE - KPT HIPPO
. These "pieces" of software allow you to trigger strobe effects on specific slices of your composition mapping rather than the entire output at once. Popular "Pieces" for Slice Strobing SLICE STROBE by KPT Hippo
: A widely used addon for Resolume Arena that creates colored strobes for specific composition slices. It supports random or sequential order modes and allows for strobing edges or flashing specific videos/images instead of solid colors RadicalSlice
: A Wire patch that enables dynamic strobe effects using Resolume’s Advanced Output. It features adjustable edge thickness, frequency, and the ability to stack multiple instances with different colors Resolume Slice Pulse/Strobe slice strobe resolume
: A simpler Wire-based patch from TechSane that uses BPM for speed control and can chase across slices in order or randomly StrobeMask (JuiceBar)
: A plugin available through JuiceBar that adds stroboscopic effects to a clip, switching between the visual and a solid color or alpha channel Key Features of These Tools Slice Selection : You can pick specific slices from your Advanced Output via a dedicated "Slices" tab in the effect panel Trigger Modes : Most offer (strobe pops up on any slice) or Chaser/Order (strobe moves sequentially across your mapping) Visual Customization
: Options often include solid fills, edge-only strobes, secondary colors, and adjustable fade/smoothness

, covering everything from built-in techniques to specialized add-ons that can transform your LED wall into a high-energy light show. Master the Flash: A Guide to Slice Strobe in Resolume Arena
If you’ve ever looked at a massive LED stage and wondered how the VJ makes specific panels flash in perfect sync with the beat, you’re looking at Slice Strobing. Whether you are using built-in effects or the popular Slice Strobe add-on, mastering this technique is essential for high-impact drops. 1. What is a "Slice Strobe"? The slice strobe in Resolume Arena is a
In Resolume, a Slice is a specific portion of your composition mapped to a physical screen or LED panel. While a standard strobe effect flashes your entire output, a Slice Strobe allows you to:
Flash specific sections of your LED wall while leaving others visible.
Create complex patterns, like strobing triangles or circles.
Trigger "chaser" effects where the flash travels across the stage. 2. Using the Slice Strobe Add-on
While you can build strobes manually, the third-party Slice Strobe Add-on by KPT HIPPO is a favorite among pros. Key Features:
Two Modes: Choose between Random (organic, chaotic flashes) or Slice Order (sequential chasers).
Custom Colors: Unlike a standard white flash, you can set specific strobe colors for each slice.
Edge Strobing: Version 1.2+ allows you to strobe just the edges of your slices for a cleaner, "neon-outline" look. The "Scanner" Slice Strobe We can emulate a
Media Flashing: Use the "Flash Video" mode to strobe actual content or logos rather than just solid colors. 3. The "Native" Way (No Add-ons Required)
If you don't want to buy extra plugins, you can still achieve great results using Resolume’s built-in Slice Transform effect.
Create Your Slices: Define your panels in the Advanced Output.
Apply Slice Transform: Drag the Slice Transform effect onto a Layer or Composition.
The Strobe Hack: Apply a standard Strobe effect after the Slice Transform. By clicking the Slices tab in the effect’s settings, you can select which specific slices the strobe should affect.
Pro Tip: Hold Ctrl+Alt while dragging the strobe effect to apply it to individual layers rather than the whole composition. 4. Tips for a Better Performance
The "Scanner" Slice Strobe
We can emulate a broken laser scanner.
- Create 8 vertical thin slices (each 12.5% width).
- Apply the
Strobeeffect to Slices 1,3,5,7. - Apply the
Strobeeffect to Slices 2,4,6,8. - Link Slice 1's Strobe interval to
LFOmapped to a Sine wave. Link Slice 2's interval to the negative of that LFO. - The strobe speed will move up and down the screen like a VU meter.
Step 2: The Strobe (The Flash)
Now we need the flicker.
- Add a new effect to the same layer. Add the Strobe effect.
- Important: Put the Strobe after the Slice in the effect chain.
- Brightness vs. Opacity: Set the Strobe Mode to Brightness (default is usually fine). Set Hold to
50%and Fade to0for a jagged on/off feel. - The Strobe Trick: Turn the Rate knob all the way up to the right (non-sync) and then map it to a BPM Knob. Set it to 1/1, 1/2, or 1/4 notes depending on the song's double-time feel.
Masking and matte techniques
- Layer masks: Use a Track Matte — place a black/white clip on a layer above and set Clip Blend to Alpha to mask which areas strobe.
- Use solid color clips: Create solids with shapes to act as masks, then invert/mult to control strobe regions.
- Advanced Output masks: In Advanced Output, import PNG alpha masks per slice for pixel-accurate strobes.
Mastering Slice Strobe in Resolume Arena
Using the FFT (Fast Fourier Transform)
Resolume allows you to map any parameter to audio input.
- Right-click the Strobe Rate knob.
- Click FFT Input -> Low (Kick drum) or Mid (Snare/Hat).
- Set the range. Map the minimum to
0(No strobe) and maximum to30(Crazy strobe).
Now, every time the kick drum hits, the Slice Strobe triggers. Because the slices are constantly shifting via the Slice Offset LFO, each kick hit reveals a different vertical chunk of your video.
Creative Use Cases for Slice Strobe
- The "Robot" Vocal Stab: Isolate a vocal clip. Add a Slice Strobe with 32 vertical slices. Map the Offset to the vocal pitch. The singer's mouth will appear to "break" into digital pixels.
- The Bass Headbang Tie: Assign the Slice Number to a LFO. During the bridge, use 2 slices (split screen). During the drop, automate it to 16 slices. The visual complexity increases with the audio energy.
- The Reverse Echo Strobe: Use Video Echo before the Slice. Set Echo Duration to 1 sec. Then apply Slice Strobe. The result is a trailing ghost that strobes behind the main action.
Creative Applications & Tips
- The "Hard Cut": Slice Strobe works best with clips that have a very distinct first frame (a flash, a logo reveal, or a high-contrast color shift).
- Blending Modes: Combine Slice Strobe with the Add or Screen blend modes. When the video snaps to the start, it will create a bright flash overlay on top of your background layers, enhancing the strobe effect.
- Tempo Halving: If the strobe looks too frantic, set your Snap Division to 2 Beats or 1 Bar. This creates a more rhythmic, "breathing" pulse rather than a machine-gun flicker.
- RetriggerFX: Use the Retrigger effect on the clip. Set the Retrigger to sync with the BPM. This simulates the slice strobe effect without changing the actual playhead position of the clip, often providing smoother results for certain file types.
