Make captions a default part of every video, not an afterthought: set a caption-first policy, write and shoot for sound-off, lock one house caption standard, keep a real accessibility track, and bake captioning into every render.

Captions stopped being an accessibility add-on and became the way most people watch video. Nearly 20% of the world — over 1.5 billion people, per the WHO — lives with some hearing loss, 430 million of them with disabling hearing loss, and captions were built for them first. But the audience has widened far past that: roughly 85% of short-form is watched on mute, around half of Americans now watch with subtitles on most of the time, and among 18–25s the share is higher still — many keep captions on even when the audio is fine, because that is simply how they read video now. The result is a cultural default flip: an uncaptioned video is no longer neutral, it is a video missing its text layer.
This guide is not about which button generates captions — that mechanics-level walkthrough lives in the linked automatic-captions tutorial. It is about the policy decision underneath it: treating closed captions as a default content format, a first-class part of every video you ship, with a house standard and an accessibility floor, instead of something you remember to bolt on per clip. The payoff is measurable — captioned video consistently shows higher completion and watch time (Facebook/Meta measured roughly a 12% lift in view time) — and it is also the difference between content a third of your audience can actually follow and content that loses them in the first three seconds.
Everything above is a policy — "caption every video, to one standard, accessibly." The hard part is not deciding it; it is keeping it true across dozens of videos a month without the default quietly slipping the first busy week. Kompozy holds the default because captions are not a step you enable, they are part of how every video format renders. A Persona Short, a Clipped Short, a Listicle Video, a Naturalistic Video, a Marketing Short — each comes out of the render already captioned, burned in through an ffmpeg/libass pipeline using a short-form caption preset. There is no per-clip caption app in the loop and no toggle to forget, which is the only way "captions on every video" survives contact with a real posting schedule.
It also enforces the two things that make a caption default worth having: one house standard and accuracy. The caption preset is set once and applied to every clip, so captions become a consistent brand element the way your color and persona are — no video re-litigates the style. And for the talking-head formats, Kompozy wrote the script before it made the video, so captions render from the known words rather than being guessed back out of the audio by a speech-to-text model — the proper-noun and brand-name errors this guide tells you to proofread mostly never appear, because the text was never uncertain. Where you do want the accessible transcript track alongside the burned-in look, the words already exist from the same run.
Then the default travels. When captions are baked into the render, every one of the nine social platforms Kompozy publishes to receives a captioned file on schedule, through autopilot and a per-post review pipeline — so "captions as a default format" is enforced at the point of production, not re-applied per platform. And once your source-language captions are standard, generating translated tracks for reach is the same engine doing the same job. Honest framing: if you post a handful of videos a month, you can hold this default by hand with a saved preset and discipline, and this guide is how. If you are shipping across formats and platforms at volume, the default only really holds when captioning is part of the render itself — that is the job Kompozy is built to do. Creator ($49/mo, 2,500 credits) fits a solo creator shipping a steady run of captioned shorts; Pro ($299/mo, 18,000 credits) handles multi-brand, high-volume output; Enterprise is custom.
Because most of your audience already watches that way. Roughly 85% of short-form is viewed on mute, around half of viewers keep captions on most of the time, and over 1.5 billion people live with some hearing loss. An uncaptioned video is not neutral — it is a video missing the text layer a large share of viewers rely on, which is why captioned video consistently shows higher completion and watch time.
Consistently, yes. Facebook/Meta measured roughly a 12% increase in average view time on captioned video, and multiple studies find higher completion rates when captions are present. The mechanism is dual-coding — viewers who both read and hear the words comprehend and retain more — plus the plain fact that muted viewers can only follow the video at all if it is captioned.
For short-form, both. Burned-in captions cannot be toggled off, survive re-uploads, and carry your brand style — best for retention. A real closed-caption or transcript track serves screen readers, search indexing, and viewers who scan — best for accessibility. Leading with burned-in and keeping a CC/transcript alongside covers both jobs; relying only on animated burned-in captions underserves the people captions were built for.
Readable pace and contrast. Keep captions to a pace a viewer can actually read (around 160–180 words per minute, roughly 30–42 characters per line as a ceiling), maintain strong contrast against the background, avoid flashing text faster than it can be read, and keep an accurate transcript. Animated styling is fine on top of that floor — it is not a substitute for it.
Move it out of your memory and into the export step. Standardize one caption preset, batch-caption on your editing day, and ideally use a pipeline that captions as a built-in render stage so a finished video comes out already captioned. When shipping an uncaptioned video takes extra effort instead of less, the default holds under pressure.
Platform auto-captions cover accessibility and are free, but they are unstyled, per-upload, and sometimes delayed (YouTube ASR can take up to a day). If captions are part of your content format and brand look, you want them burned in on your side with a consistent style, plus the platform or transcript track for accessibility — not the platform layer alone.
