For a native LinkedIn video post, upload a video file (LinkedIn lists MP4, MOV, AVI, WEBM, MKV, WMV and others) of 75 KB to 5 GB, 3 seconds (2 on mobile) to 15 minutes long, in any shape from 1:2.4 (tall) to 2.4:1 (wide), at 10 to 60 fps. LinkedIn's help pages disagree on length: the video specs say 15 minutes, an older LinkedIn Pages article says 10, so keep a Page video to 10. Captions go on from a desktop as an SRT file. Exemplary AI makes that SRT from your video, and square or vertical versions of it. Free plan: 500 one-time credits; files up to 500 MB and 30 min long; 720p video exports with a watermark. ## How to post a LinkedIn video with captions 1. Export the video as an MP4 in the shape you want. In a phone-width feed, 1:1 and 4:5 show taller than 16:9. 2. Make the captions: upload the video to Exemplary AI, correct the transcript and download it as SRT. 3. On LinkedIn from a computer, start a post and add the video, click Edit, then Select Caption and attach the SRT. 4. Write the post, up to 3,000 characters, with the point in the first line, since a long post folds behind "see more". ## LinkedIn video specs at a glance | Fact | Value | | --- | --- | | Formats | MP4, MOV, AVI, WEBM, MKV, WMV and others | | File size | 75 KB to 5 GB | | Length | 3 seconds (2 on mobile) to 15 minutes; a LinkedIn Pages article says 10 minutes | | Shape | 1:2.4 (tall) to 2.4:1 (wide) | | Resolution | 256 × 144 to 4096 × 2304 | | Frame rate | 10 to 60 fps | | Captions | An SRT file, added from a desktop (Edit, then Select Caption), or LinkedIn's own auto captions | | Post text | Up to 3,000 characters | Facts checked October 2026. ## Captions on LinkedIn: LinkedIn's own, or an SRT? LinkedIn makes auto captions for videos in English, Spanish, Portuguese, French, German, Italian, Indonesian, Turkish, Arabic and Dutch, with a step to review them before viewers see them. An SRT is the better fit when the video is in another language, when you have already corrected names and terms in a transcript, or when you want the same captions on every platform. LinkedIn's article on attaching an SRT is several years old, so if the button has moved, look for captions in the video's edit screen. For video ads, LinkedIn's ads guide suggests keeping the intro text to about 150 characters to avoid it being cut off; for regular posts LinkedIn documents no cut-off. Need the SRT? The [SRT generator](https://exemplary.ai/srt-generator) makes one from a video, and [horizontal to vertical video](https://exemplary.ai/horizontal-to-vertical-video) reframes a wide recording into 9:16, 16:9, 1:1 and 4:5. ## Ready for LinkedIn, Captions Included The file LinkedIn asks for, in the shape that suits the feed, with captions people can read on mute. ### The SRT LinkedIn asks for Transcribe the video, correct names and terms, and download a standard SRT to attach to the post. ### Square and vertical versions Cut clips or reframe the whole video in 9:16, 16:9, 1:1 and 4:5, with the speaker kept in frame. ### Captions in other languages Translate the transcript into any of 116 languages and download each as its own SRT. ### Burned in, if you prefer Export the MP4 with the captions in the picture, so they show for viewers who never turn captions on. ## Give your LinkedIn video a clear message Add captions for silent viewing, write the accompanying post, or choose a short highlight. ### [Burn subtitles into video](https://exemplary.ai/burn-subtitles-into-video) Keep captions visible wherever your video plays.
