Why we like it

Earns its place in the aescripts library for handling 100+ languages with automatic detection and offering both online and fully offline transcription.

What is AutoCaption?

AutoCaption is an Adobe After Effects plugin that automatically generates captions with styles from any audio or video. It reads common video and audio formats, including MP4, MOV, MKV, WebM, MP3, WAV, M4A and FLAC, and imposes no file-size limit because audio is extracted locally, so long videos and large files just work.

The plugin detects and transcribes 100+ languages automatically, with full right-to-left support for Arabic and Hebrew and per-character animation for Chinese, Japanese and Korean. It ships with 60+ animated caption styles, including script-matched designs, and word-by-word highlighting stays synced to the voice. Captions can be generated online or fully offline, with no connection needed.

Processing time scales with clip length, and transcription accuracy depends on audio clarity, so heavy background music or noise can reduce it. AutoCaption is built for ongoing use. Version 4.5.0 was last updated on June 26, 2026, and a demo video is available.

Frequently asked questions

Does AutoCaption work with After Effects 2026?

AutoCaption lists compatibility with After Effects 2020, 2021, 2022, 2023, 2024, 2025 and 2026, and requires After Effects CC 2019 or later. If you are on 2026 or any release back to 2020, the plugin is supported. Version 4.5.0 is the current release, last updated on June 26, 2026. Check the developer's page for the latest compatibility details before installing, since supported versions can change with new releases.

What audio and video formats does AutoCaption support?

AutoCaption works with any common video and audio format, including MP4, MOV, MKV, WebM, MP3, WAV, M4A and FLAC. There is no file-size limit because audio is extracted locally, so long videos and large files just work. Processing time scales with clip length, and transcription accuracy depends on audio clarity, which means heavy background music or noise can reduce accuracy. For anything beyond these listed formats, check the developer's page.

Can AutoCaption generate captions offline?

AutoCaption works online or fully offline, with no connection needed. Offline mode lets you generate captions even without an internet connection or when the server is temporarily unavailable, so your workflow is not interrupted. Version 4.5.0 included a bug fix for offline mode on macOS. Transcription accuracy still depends on audio clarity, and heavy background music or noise can reduce it whether you work online or off.

Does AutoCaption support right-to-left languages like Arabic and Hebrew?

AutoCaption offers full right-to-left support for Arabic and Hebrew, with proper fonts and correct RTL layout. It also handles Chinese, Japanese and Korean with per-character animation. Automatic detection covers 100+ languages, and style previews can be shown in your language. Word-by-word highlighting stays synced to the voice, and there are script-matched caption designs among the 60+ animated styles for these scripts.

Is AutoCaption free?

AutoCaption is listed as free in this catalog. For current licensing, including any subscription or perpetual options, check the developer's page on aescripts to confirm what is offered. The plugin is built for ongoing use, and as listed no credit card is required to get started. Pricing and terms can change over time, so the developer's page is the best source for up-to-date information before you commit.
