Subtitles for LinkedIn video that read at a desk.
Burn them in, or download the SRT and attach it in the composer. Restrained styles that suit a feed people scroll between meetings.
To subtitle a LinkedIn video you can either burn the subtitles into the file before posting, or attach an .srt file in the post composer using LinkedIn’s Select Caption control. LumaCaption produces both from the same edit — a burned-in MP4 and a matching SRT — and never uploads your video.
LinkedIn video is watched in the worst possible conditions for audio: on a work laptop, in an open office, between meetings, with the sound firmly off. It is also watched by people who will judge a bouncing yellow caption as a signal about the company behind it — which makes LinkedIn the one feed where the loudest caption style is the wrong answer.
You have two routes, and they solve different problems. Burned-in subtitles are part of the video, so they survive reposting, embedding and downloading, and they look exactly the way you designed them. An attached SRT stays selectable and switchable and is what accessibility guidance asks for. There is no reason to choose: the same edit produces both.
Both outputs from one pass
Export the burned-in MP4 for the post and download the matching SRT for the composer’s Select Caption control. Same words, same timings.
Thirty-seven restrained styles
The Clean lane is built for exactly this feed — editorial type, measured contrast, no bounce — with cards and lower thirds when you need to carry a brand.
Long enough for a real talk
Paid plans take 30-minute videos on Creator and 90-minute on Pro, so a conference talk or a webinar cut is one file rather than four.
Client and pre-announcement safe
Your video file is never uploaded. Only the audio is used to work out the words — which matters when the video is an unannounced product or a client’s.
Burned-in or attached SRT — which one, when
LinkedIn will auto-generate captions when you upload, and it will also accept an .srt you supply. Neither route styles anything: platform captions render in LinkedIn’s own treatment, in LinkedIn’s position, with whatever the automatic transcription heard.
- Burn them in when
- the video will be reposted, embedded on a site, downloaded by a sales team, or sent as a file — burned-in subtitles travel with the video everywhere it goes.
- Attach an SRT when
- you want viewers to be able to turn captions off, or your accessibility policy requires a real caption track rather than pixels.
- Do both when
- it is a flagship post. Burned-in for the look, the SRT for the people who need a caption track. There is no penalty for supplying both.
- Never rely on auto-captions alone when
- the video contains product names, people’s names, or Hindi and English mixed together. Those are exactly what automatic transcription gets wrong, and on LinkedIn the mistake is in front of your industry.
What actually gets watched with the sound off
Sound-off viewing changes what a caption is for. It stops being an accessibility accessory and becomes the primary channel — the words are the video. That has two practical consequences worth designing for.
First, the first line has to carry the hook on its own, because nobody hears your delivery. Second, the caption has to be readable at the size LinkedIn renders video in the feed, which is small — small enough that a two-line caption at broadcast proportions can be genuinely hard to read on a laptop. Fewer words per cue beats a bigger font here, and the pace control is the lever for that.
Names are the third thing. Automatic transcription mangles company names, product names and surnames more reliably than it mangles ordinary speech, and every word in the transcript is editable — click it, fix it, and the timing stays.
How it works
Add your talk or clip
Up to 2 minutes on the free plan, 30 on Creator, 90 on Pro. The file itself never leaves your device.
Fix the names, pick a style
Correct any product or person the transcription misheard, then choose from the Clean lane or a branded lower third.
Export both
Take the burned-in MP4 for the post, and download the SRT to attach with Select Caption in the composer.
Common questions
Does LinkedIn accept an SRT file?
Yes. In the post composer, the Select Caption control attaches an .srt file to the video before you post, and it can be replaced or removed later by editing the post. LinkedIn will also auto-generate captions if you do not supply one. LumaCaption gives you a free SRT download on every plan, with the word timings taken from your actual speech.
Should I burn subtitles in or attach the file?
Burn them in if the video will be reposted, embedded or downloaded, because burned-in subtitles travel with the file. Attach an SRT if viewers should be able to switch captions off, or if your accessibility policy requires a real caption track. Doing both is fine and often the right call for a flagship post.
What caption style suits a professional feed?
Something restrained. The 37 styles in the Clean lane are built for it — editorial typography, contrast measured against your footage rather than a fixed black box, and motion that draws no attention to itself. If the video carries a brand, the Cards lane gives you a lower third you can pin to your exact palette.
Can I caption a full conference talk?
Yes, on a paid plan: Creator takes videos up to 30 minutes and Pro up to 90. Exports are free and unlimited on every plan, so re-rendering a 40-minute talk after a copy fix costs nothing.
Is my video uploaded anywhere?
No. The video file never leaves your device — only the audio is used to work out the words and their timings. For pre-announcement product footage or client work, that is usually the deciding factor.
