What is the vocabulary from video?

The Vocabulary From Video is a free online tool from ShortsHero: study the words before you watch. AssemblyAI speech recognition does the work — a 5-minute recording usually comes back in under 30 seconds. It is free for files up to 1 hour with no watermark; longer recordings need a paid plan.

Free transcription covers files up to 1 hour. If your recording is longer, a paid plan lifts the limit — or trim it into parts and run each one.

Common questions

Is this vocabulary list from video free?

Yes. Files up to 1 hour long are free, with no watermark and no account needed. Recordings longer than 1 hour need a paid ShortsHero plan.

Which files can I upload?

MP4, MOV, WebM, MKV, MP3, WAV, M4A, AAC, OGG, FLAC and most other audio and video formats, up to 1 GB. For a long video, uploading just the audio is faster.

Can I edit the subtitles?

Yes. Download the SRT and open it in our free online SRT editor, or in any video editor, to fix a word or a timing.

How long does it take?

Usually well under the length of the recording — a 10-minute file is typically done in about a minute.

What else can ShortsHero do?

ShortsHero turns long videos into short vertical clips with AI moment detection, face tracking and animated captions — and has free tools for subtitles, transcripts and video formats.

Got a long video? Make it Shorts.

The same transcription powers ShortsHero's clip maker: it finds the strongest moments, reframes them to vertical and adds word-by-word captions in 36 styles.
