AI Relight

Add virtual 3D lights to any footage, no 3D model needed.

After Effects Premiere Pro DaVinci Resolve Nuke Product page →

1. Description

AI Relight adds virtual lights to ordinary footage. A neural network looks at every frame and estimates the shape of what is in it (which way each surface faces and how far away it is), so the lights wrap around faces and objects as if the shot were 3D.

You get up to three lights, each with its own position in X, Y and Z, color, intensity and falloff. Animate them like any other parameter, limit them to a depth range with Depth Cut, or render the light on its own to composite it yourself.

AI Relight Pro adds Temporal Consistency for steadier light on moving footage and, in After Effects, Use Comp Lights to light the shot with the point lights in your comp.

Requirements

Mac: Apple Silicon (M1 or later), runs on the GPU. Intel Macs are not supported.
Windows 10 or 11, 64-bit: uses an NVIDIA GPU (CUDA) when available, otherwise the CPU.
The Baskl installer is required: it downloads the AI model (about 150 MB) and, if not installed yet, the AI MACHINE render engine.

2. Installation

2a. Baskl installer (all host apps)

Every Baskl plugin installs through the Baskl installer. It sets up AI Machine, the local engine the plugins run on, and puts AI Relight in the right place for After Effects, Premiere Pro and OFX hosts (DaVinci Resolve, Nuke). Close your host apps before running it.

macOS

Click Download on baskl.ai, unzip Baskl.Installer.zip and open Mac/Baskl Installer.app. You need an Apple Silicon Mac; the installer stops on Intel Macs.
If macOS asks, confirm you want to open an app downloaded from the internet, then enter your Mac password so the installer can write to the system plug-in folders.
Click Let's Get Started, select AI Relight in the plugin list and click Install. The first install also downloads AI Machine, so give it a few minutes.
When you see Installation Complete, restart your host app. The effect is in the Baskl category.

Windows

Click Download on baskl.ai, unzip Baskl.Installer.zip and run Windows\Baskl Installer.exe.
Click Yes when Windows asks to allow the app to make changes. The installer needs administrator rights.
Click Let's Get Started, select AI Relight in the plugin list and click Install. On NVIDIA cards the installer picks the matching CUDA build for you. The first install also downloads AI Machine, so give it a few minutes.
When you see Installation Complete, restart your host app. The effect is in the Baskl category.

The effect is in the BSKL category.
The first render after opening your host loads the AI model, so it takes a little longer than the following frames.

Activating your license

After Effects / Premiere Pro: in After Effects, click Register at the top of the effect in Effect Controls (next to Reset), paste your license key and click Activate. In Premiere Pro, click the small icon button at the top right of the effect in Effect Controls to open the same dialog. The license is saved for the whole computer, so registering in one of the two apps covers the other.
Resolve / Nuke: click Register at the top of the effect's controls, paste your license key and confirm. Once activated, the button reads License Info.
Where to find your key: if you bought on baskl.ai, it is in your purchase email and under Account → My Licenses, with a Copy button. If you bought on aescripts + aeplugins, activate through the aescripts + aeplugins manager app, or paste the key from your aescripts account into the same Register dialog.
Without a license, AI Relight runs as a trial: everything works, but renders carry a watermark until you register. Activation needs an internet connection, and each key works on a limited number of computers (shown under My Licenses).

3. Parameters

General

Help / Contact: Opens Baskl support. We're here if you need us.
Register: DaVinci Resolve and Nuke: activate the effect with your license key. Shows License Info once activated.

Main

Output Mode: What the effect outputs.

Result your footage with the light added (default).

Light only the light, on black, so you can composite it yourself (for example with the Add or Screen blend mode).

Result against Light: only the added light.
Model Type: How the frame is prepared for the AI. Technical: leave it on Original unless the light looks wrong on your shot.

Original processes the frame at the Quality size (default).

Normalized w Padding processes the frame at a fixed size, padded to fit. Ignores Quality.

Normalized w/o Padding processes the frame at a fixed size, without padding. Ignores Quality.

Normalized w Resize normalized processing at the Quality size.
Quality: The size the AI analyses the frame at. Higher is more detailed and slower. Used with Model Type Original or Normalized w Resize.

Fastest 256 px.

Faster 512 px.

Fast 768 px (default).

Balanced 1024 px.

Detailed 1280 px.

Precise 1536 px.

Sharp 1792 px.

Accurate 2048 px.

Custom... uses Custom Resolution.
Custom Resolution: The analysis size when Quality is Custom... (256 to 8196, default 512). Hidden otherwise; Premiere Pro grays it out instead.
Use Comp Lights: After Effects only, AI Relight Pro. Adds the point lights in your comp to Light 1 to 3, seen through the active camera. Each light's color, intensity and radius are used (a larger radius gives a broader, softer highlight). Parallel, spot and ambient lights are ignored. To light with comp lights only, turn off the Enabled box of Light 1.

Temporal Consistency

AI Relight Pro. Works in After Effects and Premiere Pro.

Enable: Averages the AI's surface estimate over the current and previous frames, so the light flickers less on moving footage. Off by default.
Frames to Average: How many frames are averaged, including the current one (2 to 10, default 5). More is smoother and slower.

Depth Cut

Limits the lights to a range of depth, for example so only the foreground picks up light. The scale of the depth values depends on Model Type, so set Near and Far by eye.

Enabled: Turns the depth range on. Off by default.
Near: Where the lit range starts (-100 to 100, default 1).
Far: Where the lit range ends (-100 to 100, default 20).
Smooth: How gradually the light fades in at Near and out at Far (0 to 100, default 5).

Light 1, Light 2, Light 3

Three identical lights. Light 1 is on by default, Lights 2 and 3 are off.

Enabled: Turns this light on or off.
Position: Where the light is. X and Y place it on the frame; Z brings it toward the camera, so it lights surfaces facing the viewer more. In Premiere Pro, Z is a separate slider under the point.
Color: The light's color (default white).
Intensity: How bright the light is (0 to 500%, default 100%).

Intensity 100% against 250%.
Gamma: How quickly the light falls off as a surface turns away from it (0 to 10, default 2.2). Higher gives a tighter, more contrasty highlight; lower spreads the light more evenly.

Examples

Result: Light 1 at its default settings.
