Resolume Layers — Controls + Auto Mask
Layers are the horizontal rows of your composition — and the unit where most of the actual mixing work happens. This is the lesson where every layer control, the X/B/S buttons, the right-click menu, the way Resolume renders bottom-to-top, and the Auto Mask trick that solves the top-layer-priority problem all get walked through.
Lesson 8 in our beginner course, right after Lesson 7 on Blend Modes. Blend modes matter here — specifically Alpha — so make sure you've got those down first.
Selecting a Layer
Click on the layer's name (not the row body) — this brings up the Layer panel with the master controls for that specific layer.
Inside the Layer panel you have:
- Master Opacity + Video Opacity
- Master Blend Mode
- Width / Height
- Transition Blend Mode + Transition Duration
- Transform (Position X/Y + Scale)
Right-click any control to reset it to default. Saves a lot of "wait, what was the original value" moments.
Transport Options (per Clip, in Layer Controls)
Layer controls also let you set transport behavior for clips in that layer:
| Mode | What it does |
|---|---|
| Backwards / Pause / Forwards | Standard playback |
| Loop | Restart on end (default) |
| Bounce | Reverse direction on each end |
| Random | Jump to random timestamp |
| Play Once Clear | Stop and clear after one play |
| Play Once Hold | Stop and pause after one play |
Restart / Continue / Relative — Clip Re-Trigger Behavior
Three modes that decide what happens when you re-click a clip:
- Restart — every re-click takes the clip back to frame zero
- Continue — clip resumes from wherever it last left off (even if you triggered other clips in between)
- Relative — clip's playback position stays in sync with whatever the previously-triggered Relative clip was at. Powerful for matching beat positions across multiple clips you mix between.
Speed Controls
Speed is clip-specific — there's no layer-level speed slider. But there's a master composition speed that affects every clip in every layer at once. Useful for global tempo matching.
Blend Modes + Transitions in Layers
Two blend modes per layer:
- Master Blend Mode — how the layer composites with what's beneath it (covered in depth in Lesson 7). Rob's default: Alpha.
- Transition Blend Mode — how clip-to-clip transitions blend within this layer. Rob's default: Alpha.
Transition Duration: Rob's recommendation is to manually plug in the same duration 1-2 seconds for every layer. Consistent transition timing across layers makes mixing look clean. Use the per-layer Transition tab in the Layer panel.
X / B / S Buttons — Live Mix Controls
Three small buttons on each layer that change live mixing:
- X — kill the clip currently playing in this layer
- B (Bypass) — silence this layer entirely. Other layers still mix normally.
- S (Solo) — ONLY this layer shows. Everything else hidden until you turn solo off.
Crossfader A / B Channels
Each layer can be assigned to crossfader channel A or B. The crossfader slider then blends between the channels — gives you finer mix control than fading individual layer opacities. Especially useful with a hardware controller mapped to the crossfader.
Right-Click Layer Menu
Right-click any layer's name (or use the Layer tab menu) for the full set of options:
- New layer
- Insert above / below selected
- Duplicate
- Rename
- Copy Effects / Paste Effects — huge for re-using effect stacks across layers
- Group (covered in Lesson 9 — pending)
- Clear all clips
- Remove layer
- Create Masking Layer (future tutorial)
- Color (visual organization)
- Fold (collapse layer to save real estate)
How Resolume Renders — Bottom to Top
Critical mental model: Resolume renders layers bottom to top. Layer 1 (top) sits on top of everything beneath it. Push Layer 1's Video Opacity to 100% and the layers below disappear entirely.
Push Layer 1 to 50% and you get a blend — but the result usually looks messy because of the default blend mode.
Add Blend Mode → "White Soup"
The default blend mode for layers is Add. Add stacks the color values of every layer, which means brights get brighter and brighter and brighter — until you're staring at blown-out whiteness that Rob calls "white soup."
Switch to Alpha for cleaner layered mixing. We covered this default-change in Lesson 2 (changing the global default from Add to Alpha) — this is the WHY.
One Honest Note About Alpha
Alpha blends cleaner than Add, but it can feel dimmer. Here's why: with Add, the Video Opacity slider treats 50% as 100% (no further change above 50%). With Alpha, the slider is true-to-scale — 50% means actual 50%. You can crank it to 100% and now things actually get brighter.
Alpha isn't dimmer than Add. It's just honest about the value. Push it past 50% if you want what Add was giving you for free.
The Auto Mask Trick — Lesson Highlight
Here's the problem you'll hit: you switch to Alpha for cleanliness, crank layer opacities to 100% for proper brightness, and now the top layer hides everything beneath it again. Damned if you do, damned if you don't.
The trick: Auto Mask. Native effect inside Resolume.
- Effects tab → search Auto Mask
- Drag Auto Mask onto every layer (drop it on the layer or directly into the layer panel)
- In each layer's effect panel, find Auto Mask → bring Contrast to 1
- Crank all layer Video Opacities to 100%
Result: all layers visible at full opacity AND blending cleanly via Alpha. No more priority problem. No more dimness compromise.
Rob's recommendation: do this on every layer of every composition you build. It's the single trick that separates muddy beginner stacks from pro-looking comps.
Layer Ordering Best Practice
Once Auto Mask is in place, layer order becomes about creative choice not technical workaround:
- Top layers: overlays, masks, branded accents, effects-driven content
- Middle layers: primary content + mid-ground visuals
- Bottom layers: backgrounds, base imagery, base audio-reactive content
Experiment with order before you build out a deep stack. The same clips can look completely different at different layer positions.
Cheat Sheet
- Select a layer: click its name
- Reset any control: right-click it
- X / B / S: kill clip / bypass layer / solo layer
- Default blend mode: Alpha (not Add — avoids white soup)
- Render order: bottom to top, top takes priority at 100%
- Auto Mask trick: drop on every layer, contrast to 1, crank opacities to 100% — all layers visible, all blending cleanly
- Transition duration: match across layers (1-2s)
- Copy/paste effects: right-click → for stack reuse across layers
What's Next
Once Layers click, the next foundational topic is Groups — bundling layers so you can apply effects, control opacity, and manage them as a unit. That lesson is in production — when Rob's transcript ships, it'll land here as Lesson 9.
The full beginner course path:
- Install & interface
- Composition Settings
- Composition Layout
- Display Output
- Codec Conversion
- Audio Reactivity
- Blend Modes
- Layers (you're here)
- Groups (Lesson 9, pending)
The two highest-leverage next moves once Layers + Auto Mask click:
- Custom Transitions (Transition Phases) — Rex's trick for turning any effect into a clip-to-clip transition driver
- Effect Stacks — workflow for building and re-using effect chains (pairs with Copy Effects / Paste Effects from the right-click menu above)
