Stock Video Spec Checker

Choose a clip and this page reads its container, video codec, frame rate, frame size, duration, file size and audio tracks, then checks each one against what Adobe Stock, Shutterstock, Pond5 and Getty Images publish. The file never leaves your computer: your browser reads only the part that describes the clip, and nothing is uploaded.

Choose a clip or drop it here. It never leaves your computer: the page reads only the part of the file that describes the clip, and sends nothing anywhere.

What each marketplace checks

Adobe Stock is the strictest. It takes MOV, MP4 or MPG with H.264 or ProRes video, 5 to 60 seconds long and 3.9 GB at most, at 23.98, 24, 25, 29.97, 30, 50, 59.94 or 60 fps, in an exact list of frame sizes (1920×1080, 3840×2160 and nine others), with no audio at all.

Shutterstock takes MOV or MP4, 5 to 60 seconds, H.264 or ProRes (HEVC is accepted but not recommended), 48 fps and audio, with a 480-pixel floor on the short side (its full list of sizes is not in our sources). It states 4 GB in one help article and 10 GB in a newer one, so the checker holds to 4 GB. Pond5 takes MOV or MP4 in H.264, HEVC, ProRes or DNxHD, from 640×480 to 8192×4320, 5 to 60 seconds, under 5 GB. Getty Images publishes a 5 second minimum, a suggested 30 second maximum and a 6 GB ceiling; its lists of codecs, frame rates and frame sizes are not in our sources, so those rules show as not checked.

Why 48 fps matters

It is the one common frame rate the marketplaces disagree on. Shutterstock and Pond5 take it; Adobe Stock’s list goes from 30 straight to 50, so a 48 fps clip is refused there. A frame rate cannot be changed without changing the motion, so Rushlot does not convert it: it stops and tells you before anything is sent.

Why an audio track is a rejection on Adobe Stock

Adobe Stock does not accept audio with video, and a silent track counts: a muted or empty track still makes the file a clip with audio. A camera or an export preset can add one without you noticing. Rushlot strips every audio track before upload and copies the picture untouched; an HEVC clip loses its audio in the same pass that transcodes it to H.264. Pond5 prefers the audio removed, and Shutterstock allows it.

What pillarboxing is

Pillarboxing is black bars at the sides of the picture. It happens when a UHD timeline (3840×2160) is exported at 4K DCI (4096×2160): the file’s frame size is on Adobe Stock’s list, but the picture inside it is not full frame, and Adobe Stock rejects it. Upscaled footage is rejected the same way. This page reads the frame size the file declares, not the picture, so it cannot see bars or an upscale.

Quick tips

  • Export at the size you shot: UHD as 3840×2160, not 4096×2160, and never 1080p scaled up to reach 4K.
  • Keep clips between 5 and 60 seconds. Adobe Stock, Shutterstock and Pond5 all hold that window, and Getty Images suggests 30 seconds or less.
  • A 29.97 fps clip is fine. Rates are compared with a 0.05 fps tolerance, so 30000/1001 reads as 29.97 and 23.976 counts as 23.98.
  • Check the file you will send, not the camera original: an export can change the frame rate, the frame size and the audio.

Limits

What this tool cannot check

  • Upscaling. A 3840×2160 file made from 1080p footage reads as 3840×2160 here. Adobe Stock rejects upscaled footage, and only you know how the clip was made.
  • Pillarboxing and letterboxing. Black bars are part of the picture, and this page reads the frame size, not the picture.
  • Image quality: focus, noise, exposure, banding and compression artefacts are judged by each marketplace’s reviewers.
  • Content policy: people, property, logos, trademarks and editorial use are a reviewer’s call.
  • MPG and other containers. The page reads MP4 and MOV only. An MPG (which Adobe Stock accepts), MTS, MXF, MKV or AVI file gets a plain “cannot read” rather than a guess.
  • Rules a marketplace does not publish. Shutterstock’s frame-rate list and full size list, and Getty Images’ container, codec, frame-rate, frame-size and audio rules, are not in our sources, so they show as not checked.
  • Variable frame rate. A phone clip often varies its frame rate; the page shows the most common rate and says so.
  • Changes a marketplace makes after we read its rules. These come from each marketplace’s own pages, and its current page is the authority.
