Video translation and subtitling is one of the most time-consuming tasks for editors and content creators.
Editing the footage is already a lot of work… but writing subtitles manually and syncing them perfectly with the audio? That’s a real nightmare that can take hours — sometimes days.
Many online tools promise to solve this, but most are slow, expensive, or force you to upload your files to the cloud.
Today, I want to introduce you to AutoSubs — a powerful open-source tool that runs locally on your computer and eliminates this pain with literally one click.
What is AutoSubs?
AutoSubs is a smart AI tool that converts any video or audio file into accurate, timed subtitles, with automatic speaker identification and perfect synchronization.
It works entirely locally on your machine (no cloud upload), and you can use it as a standalone app or directly inside DaVinci Resolve.
The result? Professional-looking subtitles ready in minutes instead of hours.
