Why we like it

Doppler earns its place in the aescripts library for a focused idea: tying music playback to timeline transport so the two never overlap.

What is Doppler?

Doppler, developed by Plugnition, links a music streaming service to the After Effects timeline. When you hit play on the timeline, your music pauses, and when you pause the timeline, your music plays again. The described behaviour is simple, yet the developer notes it as remarkably powerful.

Doppler is macOS only. It runs as a panel with media control buttons, and version 1.1.0 reduced the minimum width of those buttons so the panel can be sized down. That release also added a button to hide or show the controls, along with general stability and responsiveness improvements.

The plugin is compatible with After Effects 2026, 2025, 2024, 2023, 2022, and 2021. It was first released in November 2025, with the 1.1.0 update following in February 2026. A demo video is available for those who want a closer look before installing.

Who is Doppler best for?

Doppler is best for after Effects editors on macOS who want their music streaming service to pause and resume automatically with the timeline.

How much does Doppler cost?

Doppler is completely free to download and use.

Frequently asked questions

Which After Effects versions does Doppler support?

Doppler is compatible with After Effects 2026, 2025, 2024, 2023, 2022, and 2021, covering several years of releases. It is macOS only, so it does not run on Windows. The current version is 1.1.0, released in February 2026, which followed the initial 1.0.0 release in November 2025. If you run one of the supported After Effects versions on macOS, Doppler should fit into your setup.

How does Doppler handle music playback while I work?

Doppler syncs your music streaming service with the After Effects timeline. When you hit play on the timeline, your music pauses, and when you hit pause on the timeline, your music plays. This keeps timeline playback and your music from sounding at the same time. The plugin also includes media control buttons within its panel, and a button added in version 1.1.0 lets you hide or show those controls.

Is Doppler free to use?

Doppler is listed as free in this catalog. Pricing and licensing can change over time, so check the developer's page for the current terms before you download. The plugin is developed by Plugnition and runs as a panel inside After Effects on macOS. A demo video is also available if you want to see the tool before committing to an install.
