Addons

Fonts, sticker packs, speech models, cutout models, and acceleration runtimes are optional downloads. That keeps the base install small — open Extras in the header (layers icon) when you need more.

Open the Addon Manager

• Click Extras in the header, or
• Follow an in-app prompt from the font picker, Stickers tab, auto-subtitle flow, or cutout / face-tracking / noise-removal tools.

Packages are signed .driftpkg archives. Drift verifies them before install and stores them under the app data addons/ folder.

Categories

Filter chips in Extras:

Filter	Examples
All	Everything available
Effects / Transitions / Audio FX	Shader and audio updates (core packs can patch bundled content)
Fonts	Extra typefaces for titles and captions
Stickers	Emoji and sticker packs
AI tools	Whisper speech, cutout (SAM2), face model, DeepFilter noise cleanup
AI engine	ONNX Runtime builds (CPU, CUDA, WebGPU, …)

Exact package names vary by release; install what the feature you want asks for.

What needs an addon

Feature	Typical packages
Extra fonts	Font addons
Stickers	Sticker packs
Auto captions	Whisper model + AI engine
Cut out subject	Cutout model (~190 MB) + AI engine
Face effects	Face model + AI engine
Remove noise	DeepFilter + AI engine

Effects and transitions also ship bundled with the app so editing works offline; addon updates can supersede bundled ids without a full Drift upgrade.

After install

New fonts appear in the Text inspector. Sticker packs show under Stickers. AI features unlock once both the model and a compatible engine are installed — restart or retry the action if a prompt still appears (see below for AI details).

AI-powered addons

Every AI feature needs two installs:

1. An AI engine (ONNX Runtime) — how Drift runs models on your machine.
2. The AI tool for that feature — the model weights (speech, cutout, face, or denoise).

If either piece is missing, the UI shows an install button such as Install AI engine first or Download speech recognition (about 670 MB) instead of the feature controls. Clicking it opens Extras on the right category.

Install the AI engine

1. Open Extras → AI engine.
2. Install a runtime pack for your platform (CPU always works; optional GPU packs are faster when available).
3. Under How AI runs, pick how Drift should execute models:

Option	Meaning
Automatic (recommended)	Uses the fastest option you have installed; falls back to this computer if the graphics card can’t help.
This computer	Force CPU.
NVIDIA graphics (faster)	CUDA, when that pack is installed.
Graphics card (faster)	WebGPU (or similar), when that pack is installed.

If Drift says Restart Drift for this to take effect, quit and reopen after changing the core runtime. Switching acceleration plugins on an already-loaded engine can apply without a restart.

Install AI tools

Open Extras → AI tools and install only what you need:

Tool	About	Used for
Speech recognition (~670 MB)	Whisper	Auto captions
Subject cutout (~190 MB)	SAM2	Cut outs
Face model (~5 MB)	Face landmarks	Funny Face effects
Noise cleanup (~9 MB)	DeepFilter	Remove noise

You can install several tools; they share the same AI engine.

Use auto captions

1. Select a video or audio clip on the timeline.
2. Open Assets → Text, or Properties → Audio.
3. Choose a language (or the auto / default entry in the list).
4. Click Add auto caption or Create captions from speech.

Drift shows progress (Getting speech recognition ready…, Transcribing…). Use Cancel to stop. When finished, subtitle clips appear for editing — see Captions.

If speech isn’t found, Drift reports No speech detected.

Use subject cutout

1. Select a visual clip → Properties → Cutouts.
2. Click Cut out subject… (install prompts appear if the model or engine is missing).
3. In the Cut out subject window:
   • Scrub Frame to a clear moment of the subject.
   • Left-click marks the subject (green); right-click marks areas to exclude (red). Click a marker to remove it.
   • Choose a Result: Two clips (subject + background) or Hide everything except the subject.
   • Click Cut out subject (or Cut out & apply effect when a template requested the cutout).
4. Longer clips take longer — each moment is processed. Use Cancel to stop.

Details and geometric masks: Cutouts and masks.

Use face tracking (Funny Face effects)

1. Install the face model + AI engine.
2. Select a clip → Properties → Effects.
3. Click Detect faces… (or Re-detect faces after a cut/reframe).
4. Apply Funny Face effects from Assets → Effects (Alien Head, Big Eyes, and so on).
5. Clear face track removes stored face data when you no longer need it.

Without a face track, Funny Face effects won’t lock onto people correctly.

Use noise removal

1. Select a video or audio clip → Properties → Audio → Remove noise….
2. In the Remove noise window, Drift previews a short section (~8 s).
3. Compare Original and Noise removed (Play / toggle between them).
4. Scrub the window position if you want to audition a different part of the clip.
5. Confirm to process the whole clip. Drift adds the cleaned result as a new audio track above the original — the source clip stays untouched.

Cancel closes the window and stops an in-progress run.

Opening a project that needs AI packs

If you open a .drift project saved with addons this machine doesn’t have, Drift shows Extra packs needed:

This project was saved with extra packs you don't have. It has opened, but anything they provide will not show until they are installed.

Choice	Result
Install all	Download the listed packs.
Skip	Keep editing; AI-backed looks stay inactive until you install later.

Tips

• Install the AI engine first, then the tool — the UI guides you that way.
• GPU packs need matching hardware/drivers; if results look wrong or fail, set How AI runs to This computer and retry.
• Large downloads (especially Whisper) need a network connection; Extras shows Can't reach the download store with Retry when offline.
• Removing a pack from Extras deletes its downloaded data; you can install again later.
