LinkedIn Ads video requirements
LinkedIn video ads must be MP4 files with H.264 or VP8 video, up to 500 MB, 3 s–30 min long, at a frame rate of up to 30 fps and with an aspect ratio between 9:16 and 16:9. LinkedIn recommends 30 s or less so the video qualifies for every placement across the feed and the Audience Network, and in-stream ads can be up to 90 s. The file must be uploaded to LinkedIn itself, from a desktop, not linked from YouTube or Vimeo.

LinkedIn Ads video requirements
The feed and in-stream columns share one file table; only the length differs. LinkedIn says in-stream video ads are in testing and released gradually.
| Requirement | Video ad in the feed | In-stream video ad |
|---|---|---|
| File format | MP4[1] The page also says Apple ProRes isn’t supported. | MP4[1] |
| Video codec | H.264 or VP8[1] | H.264 or VP8[1] |
| Length | 3 s–30 min; 30 s or less recommended[1] LinkedIn recommends a shorter length so the video can qualify for all placements across the feed and the Audience Network; the checker warns above it. | 3–90 s[1] The minimum comes from the general length row. In-stream ads are in testing and released gradually; you may not have access yet. |
| Resolution | at least 360 px on the short side; up to 1920 px on the long side[1] The page lists a minimum and a maximum frame size for each ratio; the checker applies the bounds they have in common. | at least 360 px on the short side; up to 1920 px on the long side[1] |
| Aspect ratio | between 9:16 and 16:9[1] The page lists a horizontal, a square and two vertical ratios, and calls one of the vertical ones recommended; the checker accepts anything between the tallest and the widest it lists. | between 9:16 and 16:9[1] |
| File size | up to 500 MB[1] The page also gives a minimum size; only the maximum is checked. | up to 500 MB[1] |
| Frame rate | up to 30 fps[1] The page says “less than”; the checker flags anything above this value and doesn’t flag exactly this value, which the page leaves open. | up to 30 fps[1] |
| Sound | Not published | Not published |
| Audio codec | AAC[1] The page also names MPEG4 audio, which is AAC in an MP4 file, so the checker looks for AAC. | AAC[1] |
| Video bitrate | Not published | Not published |
Numbers come from the platform’s own help pages (sources below). Where the platform says nothing publicly, the cell says “Not published” and the checker skips that rule.
What LinkedIn asks of video ads
Video ad in the feed
- Upload the video file to LinkedIn itself: a link to YouTube or Vimeo is not embedded.[1]
- Apple ProRes is not supported.[1]
- A video under 30 seconds loops until it has played for at least 30 seconds; a longer one plays once.[1]
- Captions must be an SRT file with plain text only: no custom formatting.[1]
- The same specs apply when you sponsor an existing organic video post as an ad.[1]
In-stream video ad
- Pair a horizontal pre-roll with a horizontal publisher or creator video; a square pre-roll can go with horizontal or vertical.[1]
- In-stream video ads are in testing and released gradually: you may not have access yet.[1]
- Upload the video file to LinkedIn itself: a link to YouTube or Vimeo is not embedded.[1]
- Apple ProRes is not supported.[1]
How to upload a video to LinkedIn Ads

Questions
What are the LinkedIn video ad specs?
MP4, H.264 or VP8 video, up to 500 MB, 3 s–30 min long and a frame rate of up to 30 fps. The size must be at least 360 px on the short side and at most 1920 px on the long side. If the file has sound, LinkedIn asks for AAC.
How long can a LinkedIn video ad be?
3 s–30 min in the feed; LinkedIn recommends 30 s or less. In-stream video ads can be up to 90 s. A video under 30 seconds loops until it has played that long.
Which aspect ratio works on LinkedIn?
Anything between 9:16 and 16:9. The page lists a horizontal, a square and two vertical sizes, so one export can serve several placements.
Can I use a YouTube link as a LinkedIn video ad?
No. The video must be a file uploaded directly to LinkedIn, not a link to YouTube or Vimeo, and it has to be uploaded from a desktop.
Does a LinkedIn video ad need sound?
LinkedIn doesn’t say that sound is required, so the checker doesn’t flag a silent file. Many people watch with sound off, so captions in an SRT file are worth adding.
