Submagic

Submagic takes a raw clip and runs the editing pass that makes short-form video watchable. You upload footage, and it lays in captions, b-roll, zooms, sound effects, and emphasis on the words that carry the point.

Recording the clip was never the slow part. The hours go to what comes after: transcribing the audio, styling the captions, hunting for b-roll, dropping a zoom on the line that matters. Submagic does that pass on its own and hands back something close to finished.

Most of the edit happens before you touch it:

• Captions transcribed and styled, with templates that match what's trending
• Key words highlighted and emojis added where they fit
• Contextual b-roll and stock footage placed on relevant phrases
• Zooms, transitions, and sound effects added automatically
• A hook title and description drafted for the post

After that you adjust rather than build. Captions, b-roll, zooms, and sound effects all stay editable, so the parts the AI guessed wrong are quick to fix. You start from a near-finished cut instead of an empty timeline. One more feature scans a long recording and pulls the moments most likely to stand on their own as shorts.

Who reaches for it:

• Content marketers turning one talking-head recording into a week of clips
• Social media managers captioning and styling clips across several accounts
• Founders and creators shipping daily short-form with no editor on staff
• Agencies producing branded short-form for a roster of clients

Brand presets matter once more than one person is publishing. You save a caption style, font, and color set, and every export from the team matches it, so three people posting to the same account don't produce three different looks.

A few specifics worth knowing:

• Captions and transcription cover dozens of languages
• Exports run from 720p to 4K in vertical, square, and horizontal ratios
• Caption templates track the styles trending on each platform
• The whole thing runs in the browser, with nothing to install

Submagic is built for fast, automated short-form. Anything bigger, a feature-length edit or a complex multi-track timeline, belongs in Premiere or DaVinci Resolve. It works on footage you already shot rather than generating video, so the raw clip is still on you.

Submagic is a paid subscription priced by exported videos, AI features, and team seats.

Best for content teams and creators putting out short-form video at volume who want the editing pass handled. Not ideal for long-form or complex multi-track work, where a full editor earns its place.
