Captions vs Submagic: Generate the Video or Finish the Short?
A practical, evidence-led decision guide. Product capabilities and limits are separated from anything that would require hands-on testing.
Captions and Submagic overlap on subtitles, social edits and translation. Their centre of gravity differs: Captions is a mobile-first generative production environment; Submagic is a caption-first short-form finishing system with long-form clipping sold separately.
Choose from the input
Start with Captions when the team may create actors, ads, B-roll, voices or complete social video inside the product. Start with Submagic when source footage and chosen moments already exist and the job is to caption, trim, brand and publish them.
For long podcast repurposing, neither base price tells the whole story: Submagic's Magic Clips is an add-on, while Captions' clip/edit functions draw from plan and feature limits.
Meters resist a one-line price table
Captions' reviewed iOS plans range from Max $24.99/500 credits to Scale tiers with 1,400–5,600. Feature rates vary from one credit per output second for Creator/Ads/Skits to eight for Prompt to Video and 10–40 for AI Edit. Device limits differ between iOS and desktop.
Submagic's monthly plans count finished videos per member: 15 at Starter $19, 40 at Pro $39 and 100 at Business+API $69, with duration and export gates. Magic Clips and API minutes are additional capacity decisions.
Compare one real calendar:
`Captions cost = plan + feature credits/upgrade + correction labour`
`Submagic cost = seats + Magic Clips + API packs + correction labour`
Test a generated ad and a recorded short
For the generated ad, give both the closest available workflow but do not penalise Submagic for lacking actor generation; record that as product fit. For the recorded short, use the same one-minute footage with difficult names, numbers, music and two speakers.
Score caption words/timing, safe area, brand style, cut logic, generative-asset rights and time to approval. Run Captions on the actual production device.
For the recorded-short round, include a difficult proper name, a price, an interruption and a disclaimer. Have one editor correct both results without knowing which product made them. Record correction actions rather than asking which template “looks better.” A caption system that is stylish but repeatedly changes numbers cannot pass a commercial workflow.
For the generated-ad round, retain the actor, voice, B-roll and music provenance. Captions can create more of the asset, which means it can also introduce more items that need rights and claim review. Submagic's narrower role may leave more source work outside the platform but can make the evidence chain simpler.
Team economics diverge
Submagic's reviewed plans are priced per member and count completed videos. Captions' self-serve surface is plan/credit-led and device-sensitive. A five-person review team may therefore face very different access costs even when one person creates every asset. Determine who needs editing access, who can review through exports and whether enterprise controls are required. Do not multiply or ignore seats by habit.
Verdict
Captions is the stronger candidate for creating or transforming the whole mobile social asset. Submagic is the more legible purchase when finishing volume and caption style are the job. Neither should win from “AI features” alone; price the exact mode and add-on.
