Vertical stock video: specs and rules by agency

Vertical stock video requirements by agency

All three agencies take vertical clips. Shutterstock and Adobe Stock publish the same four vertical resolutions; Pond5 publishes none and sets a file size cap instead. Everything else follows the usual video rules.

Two agencies also say there is demand. Shutterstock’s mobile article states that “vertical videos are in high demand for social media.” Adobe’s video overview lists vertical video for social platforms, 9:16 content made for Instagram Stories, TikTok and similar formats, among its high-demand themes. It adds that mobile-captured vertical video “performs on par with professional cinema camera videos when both meet technical and creative standards.”

48 fps is the one rate to avoid if a vertical clip also goes to Adobe Stock, which does not list it. The reasons behind each rate are in the stock footage frame rates guide.

Native 9:16 or rotated? Where Shutterstock disagrees with itself

Three Shutterstock help pages deal with vertical video, and they do not agree.

• The technical requirements page (17 December 2025) accepts “horizontal or vertical” orientation and lists four vertical resolutions.
• The mobile video article (13 March 2026) asks you to “rotate vertical clips into a horizontal position before submitting them for review,” to optimize how they display on the site.
• The orientation article (16 July 2025) rejects content that is “oriented incorrectly or flipped,” including a vertical image submitted horizontally and a vertical video submitted upside down.

Adobe takes the opposite line to the mobile article: “Shoot vertical video natively and upload video in the 9:16 aspect ratio. Do not convert the video to 16:9 and upload horizontally.” Placing a vertical clip inside a 16:9 frame with black bars on both sides does not help either: that is pillarboxing, which Shutterstock rejects unless the footage is archival.

The orientation article also describes a trap that hits phone footage. Preview software on your computer can correct the orientation for viewing “without changing the actual orientation of the file.” A clip that looks upright in your file browser can reach the reviewer sideways. Open it in your editor and export a new file, so the rotation is written into the picture itself.

Shoot vertical or crop a horizontal clip?

A 9:16 crop keeps the full height of a horizontal frame and takes 9/16 of that height as its width. From UHD, that leaves 1215x2160 pixels, which scales down to a valid 1080x1920 file. From 1080p, the crop is about 608x1080 and would have to be enlarged to reach any listed size.

Upscaling is where crops fail. Adobe refuses upscaled video, with HD to 4K as its example, and Shutterstock lists pixelation from upscaling as a quality fault. A crop from 4K therefore tops out at HD, and a crop from 1080p cannot be used at all.

Crops also meet the similar-content rules. Shutterstock rejects a cropped or reformatted copy submitted next to the original, then adds an exception: “1 horizontal and 1 vertical orientation of the same unmoved subject is allowed.” The article does not say whether that vertical version may be a crop. The safe route for both agencies is a separate vertical take: turn the camera, reframe for the tall frame and roll again. The rules on variants are in similar content rejections.

Vertical clips from a phone

Phones are the usual source of vertical footage. The agencies accept them under conditions:

• Use the rear camera. Shutterstock notes that on most phones the user-facing camera has a much lower resolution, and asks for the highest resolution settings.
• Transfer by cable. Emailing or messaging a clip loses quality, which Shutterstock says can lead to unacceptable noise and grain.
• Record 1080p or more. Pond5 sets 1080p as the minimum for smartphone footage.
• Frame for the tall format. Shutterstock warns that filming vertically makes it easier to crop out the subject by accident.
• Keep it steady. Unintentional abrupt movement can lead to rejection, per the same article.

Two phone defaults need attention before export. Many recent phones record HDR video in HEVC (H.265). Shutterstock accepts H.265 but does not recommend it, citing a known HDR compatibility issue, and prefers Rec. 709; Adobe’s codec list does not name H.265 at all. Our advice: turn HDR video off, or export an SDR Rec. 709 version in H.264 or ProRes. Some phones also record at a variable frame rate, so export at a constant rate taken from the agency lists. Codec choices are compared in ProRes or H.264 for stock footage.

File size: Pond5’s 3 GB cap on vertical clips

Pond5 caps vertical footage at 3 GB, the same as HD, even when the clip is 4K. A 2160x3840 frame holds as many pixels as UHD, so in ProRes it reaches that cap well before 60 seconds. The estimates below use Apple’s published target data rates for UHD; real files vary with the picture.

Shutterstock’s 10 GB and Adobe’s 3,900 MB leave more room, but a 60-second 4K vertical clip in ProRes 422 HQ at 30 fps, about 6.6 GB, fits neither Adobe nor Pond5. Trim the clip, step down to ProRes 422 or LT, or export H.264 at a high bitrate.

Length, titles and keywords for vertical clips

Adobe is the only agency with vertical-specific advice. It recommends 10 to 30 seconds per vertical clip, inside the usual 5 to 60 second limits, and asks you to include the keywords “vertical” and “video” in titles and keywords “for optimal search results.”

Shutterstock and Pond5 have no vertical keyword rule, so their usual limits apply: 7 to 50 English keywords and a one-sentence description at Shutterstock, an English title of 40 to 80 characters and up to 50 keywords at Pond5. Add “vertical” once, if it describes the clip. Shutterstock counts the same word or word stem repeated across keywords as spam, so “vertical,” “vertical video” and “vertical format” in one list is a risk.

The method for the rest of the list is in how to keyword stock footage, and the video spec checker compares a vertical file’s resolution, frame rate and length with each agency’s list before you upload.
