A Submagic alternative for people who also make the video

Submagic turns an uploaded video into a captioned vertical short, quickly and well. Here it is next to a Short engine that sits at the end of a studio.

Updated September 8, 2026 · 4 min read

Submagic does one job: you upload a video, it transcribes it, styles the captions, and gives you back a short. It is fast, the styles look current, and for a lot of people that is exactly the right size of tool.

The comparison here is not style against style. It is a single-purpose tool against a Short engine that sits at the end of a studio, a recording library and an editor.

Where the two differ in shape

Where the Short comes from. With a dedicated shorts tool the workflow starts with an upload: you find the file, you wait for it to go up, you wait again. Here the source is already in the product. Shorts can be produced automatically when a broadcast ends, or started from any video of ten minutes or more sitting in Storage. Nothing is uploaded twice.

How passages are chosen. Not an even division of the running time. Silence detection finds where speech actually pauses, candidate ranges are scored on how cleanly they start and end and on how continuous the speech is, and boundaries are snapped to a real pause so a Short does not cut through a sentence. On the plans that include it, a second pass transcribes the candidates and reranks them on whether the passage carries a complete point. Pressing again produces a set from different passages rather than the same ones.

Framing. The vertical crop is centred on the speaker, using face detection that runs locally on sampled frames rather than a paid vision call. When two people are too far apart to fit one vertical window, the Short is rendered as two stacked tiles instead of cutting somebody out of frame. Output is 1080 by 1920 for 9:16, with 1:1, 4:5 and 16:9 available depending on plan.

Hebrew. This is the part most caption tools get wrong. Right-to-left cues are rendered through a headless browser rather than the usual subtitle renderer, because that renderer reverses word order the moment a word-by-word highlight is applied. The result is Hebrew that reads in the right order with the highlight still moving across it. Punctuation direction is handled explicitly, and a Latin-only font is swapped for a Hebrew-capable one rather than showing boxes.

What is behind it. Every Short is one output of a larger pipeline. The same recording can go through the translation studio, where the transcript carries a timestamp per word, more than eighty caption designs are available, lines can be split, merged and retimed by hand, and the result can be exported as SRT, VTT or ASS or burned into the picture. Short captions can be corrected afterwards too: edit the lines, choose a style, and the Short is re-burned from a clean copy.

Where Submagic is still ahead

This is the honest part, and it is a real list.

• A much larger, more current style library. Submagic maintains many caption looks and refreshes them against what is doing well right now. Shorts here render with nine built-in caption engines, not the eighty-plus designs available in the editor. If you want this week's look, they have it and we do not.
• It writes the words around the video. Hooks, titles, descriptions and hashtags per short are part of what Submagic produces. We do not generate any of that — Shorts come out numbered, and you write the caption yourself.
• Trend-driven motion. Zoom punch-ins, sound effects and stock cutaways are a routine part of their output. Here cutaways and a music bed depend on a media library being configured, and there is no automatic zoom.
• Turnaround on a single file. If you have one video and you want one short, a tool built for exactly that will be quicker than a pipeline that also transcribes, reframes and renders several variants.
• Right size, right price. If you never stream, never run a podcast and never open an editor, buying a studio to get captions is the wrong shape of purchase, and their pricing reflects a narrower job.

A short comparison

Which to choose

If shorts are the product — you receive files from clients or record on a phone, and what you need is a captioned vertical Short with the current look and a hook written for you — Submagic is built for that and it is good at it. If the video starts in your own studio and the Shorts are one of four things you need out of it, alongside the recording, the translated captions and the published post, then having the Short engine at the end of that pipeline saves an upload, an export and a second subscription.

Frequently asked questions

Do the Shorts come out with captions burned in?

On the plans that use the AI selection pass, yes, in one of nine caption engines including a word-by-word highlight. Captions can also be corrected afterwards and re-burned from a clean copy of the Short.

Can I download an SRT file for a Short?

Not for an automatically generated Short — its captions live burned into the MP4. Subtitle files in SRT, VTT or ASS come from a translation project in the editor.

How is Hebrew handled differently?

Right-to-left cues are drawn through a headless browser instead of the usual subtitle renderer, which reverses word order as soon as a moving highlight is applied. Punctuation direction is marked explicitly and a Hebrew-capable font is substituted when the chosen design is Latin-only.

Does it write titles and hashtags for me?

No. Shorts are produced numbered and you write the post text yourself. If automatic hooks and hashtags are the main thing you want, a dedicated shorts tool will serve you better.
