How to Use Submagic: A Captioner, Not a Camera

Submagic is a captioner and a finisher, not a camera or a full long-form clip finder. You hand it a clip you already shot, and it transcribes the audio, lays down animated, word-by-word captions, and tidies up the sound and pacing before the video goes out. It will not film for you or write your script, and its base workflow is not built to find moments inside a two-hour podcast. Those jobs belong to Opus Clip or another of the Submagic alternatives.

Which is why this guide leads with what the tool is before it touches a single button. Pin down the boundaries and the rest, your files, your plan, your spend, follows from there.

The one input Submagic assumes you already have

Every workflow in the app starts from footage you shot elsewhere. You upload a talking-head clip, set the spoken language and the number of speakers, and click "Generate Captions." In about 40 seconds it transcribes the audio and adds animated, word-by-word captions, which is the feature people pay for. From there you trim, clean the audio, add B-roll and zooms, then export or publish.

Read that sequence again and notice what is missing from the front of it. There is no recording step and no text-to-video step. Submagic captions and finishes footage rather than filming it or generating video from a prompt. Its ideal input is scripted or spoken content with clear audio: a piece to camera, a product explainer, a short interview cut. Vertical, voice-driven footage with clean, close-mic audio gives it the most to work with.

The tool runs in your browser on Windows or Mac. There is no native desktop or mobile app yet, though a mobile app has been listed as in progress, so plan to edit at a computer.

The three jobs people wrongly assume it does

Three expectations account for most buyer disappointment, and all three are about the tool's edges rather than its bugs.

It does not turn a long video into short clips as part of the base product. That is the Magic Clips add-on, a separate purchase at +$19 a month (+$12 annually) layered on top of a paid subscription. It processes a long upload in roughly 10 to 25 minutes and returns 20+ clips, each with a virality score. It is not in any base plan, so budget for it separately if long-to-short clipping is your main job. Base Submagic assumes the clip you hand it is already cut.

It does not translate the audio of your video. Its AI translation adds translated subtitles and keeps your original voice and audio intact, so it is not voice dubbing or lip-sync. That reaches viewers who read along, but it is not a localized voiceover, so say so if a market expects native audio. Caption translation is a Pro feature, and the language count depends on the source: the caption interface cites 48 languages while translation is advertised at 100+.

And it does not handle every script equally. Right-to-left languages are the weak spot, so run a short test clip before trusting it with Arabic, Hebrew, Urdu, or Persian content.

Where the transcription holds and where it slips

Captions are strong on clean English audio. Submagic markets 99 percent accuracy across 48 languages, but real-world results on messy audio land lower. Accuracy drops on heavy accents, fast speech, background noise, and brand names or jargon. A silent or music-only file generates nothing at all, because Submagic only captions what it hears.

The practical consequence is a proofreading pass you cannot skip. After generation, click "Edit Captions" and fix any wrong words before you go further, because a wrong word inside a big animated caption is glaring in the final cut. In the same pass you can reposition and resize the text, emphasize specific words, and add or remove emojis. Feed it a noisy voice memo or heavily accented speech and that cleanup pass grows, which is time the tool was supposed to save you.

Why the length caps, not the price, decide your plan

The free plan (which Submagic also calls a free trial) gives you 3 videos a month, each capped at 1 minute 30 seconds, with a Submagic watermark burned into every export and no AI credits. That mix tells you what it's for: three short clips get captions and a style pass, but the burned-in watermark and the total absence of AI credits for B-roll or cleanup mean nothing leaves the free plan looking finished. Removing that watermark is the main reason to move to a paid plan.

On the paid tiers, the per-video length cap matters more than which tier you pick, because it is the wall you hit first:

• Starter is $19 a month ($12 if you pay annually): 15 videos a month at up to 2 minutes each.
• Pro is $39 a month ($23 annually): 40 videos at up to 5 minutes, and it adds the Brand Kit, post scheduling, and caption translation.
• Business + API is $69 a month ($41 annually): 100 videos per member at up to 30 minutes, with unlimited seats and 4K export.

Pricing is per member, so a team multiplies the monthly figure by the number of seats. Annual billing lands around 37 to 41 percent cheaper. The mistake here is buying on video count and ignoring length: a podcaster on Starter or Pro hits the 2 or 5 minute wall immediately, and Starter's 15 videos a month runs out fast for anyone posting daily. If your source is long-form, you either need Business or you cut clips first somewhere else.

The file rules that decide whether your upload even loads

Format trips people up more than they expect, and getting it wrong is a top cause of failed uploads. Before you touch the dashboard, export your clip to meet these criteria:

• An .mp4 file with the H.264 codec.
• A whole-number frame rate of 30 or 60. Decimal rates like 29.97 or 59.94 break things.
• SDR Rec 709 color rather than HDR, or your colors can shift and wash out on export.
• Under the 3 GB per-video size ceiling, per Submagic's format doc.
• Within your plan's length cap: 1:30 on Free, 2 minutes on Starter, 5 minutes on Pro, and 30 minutes on Business.

When an upload fails, the usual culprits are a format that misses one of those points or an unstable connection. Pre-compressing with Handbrake also causes trouble, so if you must shrink a file, use a different compressor. Check the file first, then retry.

Working the editor in the order it expects

Once a clean file is in, the app is built to be worked top to bottom. Knowing the order keeps you from paying for steps twice.

From the dashboard, "Generate Captions" opens the core flow. Click through "Generate AI Captions" and use "Click to upload or Drag & drop." The neighboring "Clip Videos" / "Get Magic Clips" path is the long-form add-on described above, not where most new users should start.

After captions come down and you have proofread them, style them. Browse the caption template library, which Submagic describes as 35+ animation presets, and pick one or build your own. You can adjust color, font, weight, and size on any preset, though custom templates are limited to Pro and Business. Styling is quick and trend-matching is easy, but granular per-word control is limited next to a dedicated subtitle editor, so it favors speed over pixel-perfect brand control.

Next is the AI Auto Edit. In the Trim section, text-based trimming cuts by deleting words from the transcript instead of scrubbing a timeline, and it is available from Starter up. The heavier cleanup steps sit here and are mostly gated to Pro and above: "Remove Silences" and "Remove Bad Takes" strip dead air and flubbed lines, "Clean Audio" improves the sound, and "Correct Eye Contact" nudges your gaze back toward the camera. Want an intro hook? "Generate Hook Title" auto-writes one you can adjust for text, font, style, and duration, and AI hook titles are a Pro feature. Under color adjust you can shift brightness, saturation, and temperature.

Then dress the picture. Click "B-rolls" and use "Magic B-roll" to auto-insert stock footage that matches your transcript. Starter includes free B-roll; Pro and Business add the Storyblocks library. Auto B-roll is helpful but imperfect and usually needs a review pass, so use "Change Media" to swap anything that misses. You can also add transitions between scenes and apply "Zoom Effects" or "Magic Zoom" for automatic smooth zooms that keep a static shot moving. For anything client-facing, set up the Brand Kit so your fonts, colors, and logo stay consistent across projects. Brand Kit starts on Pro; adding logos, brand assets, and a custom pronunciation dictionary for tricky brand names is a Business feature.

Finally, export. Click "Export" in the top right and pick your quality and frame rate. Starter exports 1080p at 30 FPS, Pro adds 2K at 30 FPS, and Business goes up to 4K at 60 FPS. Free-plan exports carry the watermark; every paid plan removes it, and a render usually takes a minute or two. Run a short test export early, because font weights, colors, and emoji placement can render differently in the final file than in the preview, and every re-render eats into your monthly video count. When you correct the source and need a clean re-export, the "Replace Video" feature swaps the underlying clip without redoing your caption edits.

From there you download the finished MP4 or publish straight from the editor. The built-in scheduler posts to TikTok, Instagram (Reels), YouTube Shorts, LinkedIn, Facebook, and X. "Publish Now" works even on the free tier, but scheduling a post for a future date or time requires Pro or Business. For a multi-platform push, select every platform on the publish screen, tailor each one's caption, set the time, and Submagic posts on schedule.

The metered currency, and the charge that lands quietly

Two costs sit outside the plan price and catch people off guard.

The first is AI credits, the metered currency you get 3 of on Starter, 6 on Pro, and 15 on Business each month. The generative steps spend them: prompt-generated AI B-roll, AI images, and the AI cleanup functions all draw down credits faster than you would guess. Lean on free stock B-roll for anything generic and save the credits for shots you cannot source otherwise, or you run dry mid-month and are into buying credit packs or waiting for the reset.

The second is renewal. Submagic auto-renews monthly plans every month and annual plans every 12 months. Submagic's own help article says it does not refund SaaS fees, though the current Terms of Use grant EU consumer buyers a 14-day right of withdrawal that professional accounts do not get. If you publish regularly and choose annual billing, set a calendar reminder before renewal; the vendor also documents a subscription-pause option for a temporary break.

FAQ

What can you do on Submagic's free plan?

Sign up with an email or Google account, no card required. The free plan (Submagic also calls it a free trial) gives you 3 videos a month, each up to 1 minute 30 seconds, with a Submagic watermark on every export and no AI credits. With zero AI credits you can't run B-roll or the cleanup tools, and the watermark stays put until you upgrade, so the free plan will caption and style a clip but can't hand you a finished one.

How does Submagic make the video?

You upload a clip you already shot, set the language and number of speakers, and click "Generate Captions." In about 40 seconds it transcribes the audio and adds animated, word-by-word captions. From there you trim, clean the audio, add B-roll and zooms, then export or publish. It captions and finishes footage rather than filming for you or generating video from a text prompt.

Does Submagic turn a long video into short clips?

Only with the paid Magic Clips add-on, which costs +$19 a month (+$12 annually) on top of a subscription. It processes a long upload in roughly 10 to 25 minutes and returns 20+ clips, each with a virality score. It is not part of any base plan, so budget for it separately if long-to-short clipping is your main job.

Can Submagic translate my video into other languages?

It translates the captions, not the audio. Submagic adds translated subtitles and keeps your original voice and audio intact, so it is not voice dubbing or lip-sync. Caption translation is a Pro feature, and the language count depends on the source, with the caption interface citing 48 languages and translation advertised at 100+.
