Summary
The Film Halation Effect for After Effects is a $36 pack that adds the warm red-orange glow film stocks produce around bright highlights. You apply it to a layer or an adjustment layer in the timeline, then shape the bloom in the Effect Controls panel using intensity, spread, softness and hue. It runs natively in After Effects with no third-party plugins required, and behaves correctly in 32-bit float projects.
What Is the Film Halation Effect?
When light is bright enough on film, it passes through the emulsion, reflects off the back of the film base and re-exposes the frame from underneath, slightly offset from where it entered. Red scatters most through the base, so the resulting halo skews warm. That is halation: the orange-red bleed around windows, practicals and specular hits that characterises 35mm and 16mm stocks like Kodak Vision3.
The Film Halation Effect recreates it on digital footage, giving bright highlights a soft, dreamy bloom instead of a hard clipped edge. The pack includes:
- Film halation presets — so you are not rebuilding a duplicate-layer, luma-key, blur, tint and blend-mode chain from scratch every time.
- Adjustable glow controls — intensity, spread, softness and hue, exposed in Effect Controls and fully keyframeable.
- Looks inspired by real motion picture stocks — the halation characteristics follow how real stocks respond.
- Native support — nothing third-party to install or license, which also means no missing-effect warnings when a project moves between machines.
It is $36.00 and also covers Final Cut Pro, DaVinci Resolve and Premiere Pro.
How Film Halation Works in After Effects
After Effects is the one application in this list where halation is naturally a compositing operation rather than a colour operation, and where you have the most control over how the glow is generated and recombined.
-
Install the presets — quit After Effects and copy the preset files into
Documents/Adobe/After Effects [version]/User Presets. Relaunch and they appear in the Effects & Presets panel under * Animation Presets > User Presets. You can also apply a preset file directly with Animation > Apply Animation Preset without installing it. - Set the project to 32 bits per channel — click the bit-depth indicator at the bottom of the Project panel while holding Option (Alt on Windows), or use File > Project Settings > Color. Glow falloff over 8-bit will band, and 32-bit float also preserves the over-range highlight values that make the bloom behave sensibly.
- Add an adjustment layer — Layer > New > Adjustment Layer (Command/Ctrl-Option-Y). Put it at the top of the layer stack, above everything you want treated.
- Apply the halation preset to it — double-click the preset in Effects & Presets with the adjustment layer selected, or drag it onto the layer.
- Open Effect Controls — F3 with the layer selected. Set intensity, then spread for how far the glow travels, softness for the falloff, and hue to bias it warmer or cooler.
- Check it over motion, not a still — RAM preview a full shot (spacebar). Moving specular hits are where an overcooked setting shows up as pulsing.
Precomps, Order and Comping Notes
After Effects renders bottom to top within a layer, and inside-out through precomps. A few consequences worth knowing:
- Grade inside, glow outside — if your colour work lives inside a precomp, put halation on an adjustment layer in the parent comp so it sees the graded result. Applying it inside the precomp alongside the grade makes ordering depend on effect stacking rather than comp structure, which is harder to reason about later.
- Collapse Transformations changes what the adjustment layer sees — with the collapse switch on, the nested comp is rendered in the parent's coordinate space and adjustment-layer effects apply differently. Turn it off if the glow is landing in unexpected places.
- Adjustment layers only affect layers below them — an obvious rule that still catches people. If a title or graphic should not glow, put it above the adjustment layer, not below.
- Trim the adjustment layer — the layer bar defines the range. Trimming it is cheaper than keyframing intensity to zero, and it saves render time on shots that do not need the effect.
- Linearize Working Space is a judgement call — with it on in Project Settings, blurs and blends compute in linear light, which makes glow spread more physically. It also changes every other composite in the project, so switch it deliberately, not mid-job.
Render Performance
- Blur radius is the cost driver — spread is the most expensive control in the pack. If previews are slow, reduce spread first and compensate with intensity rather than the reverse.
- Multi-Frame Rendering helps on export, not scrubbing — check it in Preferences > Memory & Performance. It parallelises frames, so it pays off in the Render Queue and in longer previews rather than on single-frame scrubs.
- Drop preview resolution while tuning — set the Composition panel to Half or Third, then go back to Full to judge falloff and check for banding. Reduced-resolution previews smooth over exactly the detail you are evaluating.
- Pre-render heavy sections — Composition > Pre-render gives you a rendered proxy for a locked section so you are not recalculating the glow on every playthrough.
- Export in a high-bit-depth codec — a 32-bit float project exported to 8-bit H.264 can reintroduce banding in the glow falloff. Render to ProRes 422 HQ or better if the delivery allows, or add grain on top, which dithers the gradient.
When to Use It in After Effects
The reason to do halation here rather than in an NLE is usually that other elements need to interact with the glow:
- Titles and graphics — text sitting over a bright practical looks pasted on if the practical blooms and the text does not. In After Effects you decide layer by layer what participates.
- 3D renders and CG elements — a clean render with a hot area and no halation is one of the fastest giveaways that a shot is synthetic.
- Keyframed changes — a light coming on, a car headlight sweeping past camera, a practical dimming. Intensity and spread are keyframeable, so the glow can build with the light.
- Beauty and product work — controlled specular hits benefit from a warm bloom that a sensor simply will not produce on its own.
If you are still setting up the colour side of the pipeline, the step-by-step grading guide covers the order of operations that halation slots into.
Conclusion
After Effects gives you the most granular halation of the four supported apps: a 32-bit float project, an adjustment layer at the top of the stack, keyframeable controls, and full say over which layers glow and which do not.
The Film Halation Effect is $36.00, includes intensity, spread, softness and hue controls, and runs natively in After Effects with no third-party plugins required. Work in 32-bit, tune spread before intensity, and finish with grain over the top.
FAQ
Q: Where do animation presets install in After Effects?
A: Documents/Adobe/After Effects [version]/User Presets. Relaunch the app and they appear in Effects & Presets under * Animation Presets > User Presets. You can also apply a preset file directly via Animation > Apply Animation Preset.
Q: Do I need to work in 32-bit float?
A: It is strongly recommended. Glow falloff over 8-bit banding is the single most common complaint with any bloom effect, and 32-bit float also preserves over-range highlight values that make the effect behave predictably.
Q: Should it go inside the precomp or in the parent comp?
A: In the parent comp, on an adjustment layer above the precomp. That way it sees the fully graded result and your comp structure, rather than effect stacking order, controls the pipeline.
Q: Can I keyframe the glow?
A: Yes. Intensity, spread, softness and hue are standard effect parameters in Effect Controls, so they animate like any other property.
Q: Why is my adjustment layer not affecting everything?
A: Adjustment layers only affect layers below them in the stack, and Collapse Transformations on a nested comp changes how the effect is applied. Check both before assuming the preset is at fault.
Q: Why does the glow band after export?
A: Exporting a 32-bit project to 8-bit H.264 reintroduces stepping in smooth gradients. Render to ProRes 422 HQ or better if you can, or add a grain layer above the halation to dither the falloff.
