Submagic

What Submagic is

Submagic is a captioning and packaging tool for short video. It generates subtitles with highlighted keywords, emoji and template styles so clips work when watched silently, and adds B-roll, transitions and rhythm adjustments.

The platform also produces titles, descriptions and tags for publishing, and imports from links or files.

What you can do with it

• Caption clips automatically with keyword emphasis
• Insert B-roll without manual searching
• Apply transitions and tempo optimization
• Generate publish-ready titles and tags

Who it is for

• Short video creators at volume
• Podcast teams producing clips
• Content matrix operators
• Marketing teams packaging social video

What to watch out for

• Auto B-roll can distract from the spoken point; review insertions
• Emoji-heavy caption styles do not suit every brand
• Captions need proofreading for names and terms
• Generated metadata should match actual content
