Why we like it

SpeedX earns its place in the aescripts library as an AI-driven time remapping option that spans both After Effects and Premiere Pro, with its Sharp mode and optical flow refined in a 2024 update.

What is SpeedX?

SpeedX is a time remapping tool for After Effects and Premiere Pro that uses AI technology to handle retiming. Because it leans on AI processing, its performance is highly dependent on your GPU card, and the developer recommends trying it before purchase.

The plugin's Sharp mode was refined with more accurate optical flow and set as the default mode in a 2024 update. Support for Multi-Frame Rendering and Apple M1 Silicon arrived in earlier releases, and later fixes addressed flicker, memory leaks, a macOS load issue and general stability.

SpeedX runs across After Effects and Premiere Pro from the 2020 through 2026 versions. The current build is 2.0.1, last updated on September 22, 2024. A demo video is available, and the developer's page lists the full version history.

Who is SpeedX best for?

SpeedX is best for artists retiming footage in After Effects and Premiere Pro who have a capable GPU card.

How much does SpeedX cost?

SpeedX is completely free to download and use.

Frequently asked questions

Which After Effects and Premiere Pro versions does SpeedX support?

SpeedX runs in After Effects and Premiere Pro across the 2020, 2021, 2022, 2023, 2024, 2025 and 2026 versions. That range applies to both hosts, so if you work in either application on a current or slightly older release, the plugin is covered. For confirmation of the exact build you're running before you install, the developer's page is the place to check the latest compatibility details.

Does SpeedX need a powerful GPU?

SpeedX is a time remapping tool powered by AI technology, and its performance is highly dependent on your GPU card. Because results tie so closely to graphics hardware, the developer recommends trying it before purchase to see how it runs on your own system. Testing on the machine you'll actually use is the most reliable way to gauge what to expect from the plugin.

Does SpeedX work on Apple M1 Macs?

SpeedX added support for Apple M1 Silicon in an earlier update, so it runs on M1-based Macs. A later fix also addressed a load issue on macOS, which arrived in the September 2024 release. If you're on Apple Silicon, the plugin is built for that architecture. Checking the developer's page for the most current macOS notes is still worthwhile before you install.

What changed in SpeedX's Sharp mode?

SpeedX improved its Sharp mode with more accurate optical flow, and made Sharp mode the default in that same update. Those changes landed alongside a macOS load-issue fix in the September 2024 releases. Earlier versions addressed flicker, memory leaks and overall stability, and added Multi-Frame Rendering support. The developer's page carries the full changelog if you want the complete record of what each release fixed.
