Stock video spec checker

What the spec checker looks at

The tool reads the header of your MOV or MP4 file, the part that describes the video without decoding it. That is enough to know the format, codec, resolution, frame rate, length and audio tracks, even for a 5 GB ProRes file, in a fraction of a second.

The complete lists of resolutions and codecs are on the stock video requirements comparison and on each agency page.

What it cannot check

A clip can pass every technical check and still be rejected. Review teams look at the image itself: focus, noise, exposure, white balance, stabilization, visible logos and brands, recognizable people without a release, and whether your metadata describes what is in the clip.

The list of rejection reasons covers all of these, with how to avoid each one. For the metadata, use the title and keyword checker.

Fixing the usual failures

• Resolution not on the list: export to the nearest accepted size, for example 3840x2160 for UHD. Avoid upscaling HD to 4K: Adobe Stock rejects upscaled video.
• Frame rate refused: high frame rates such as 100 or 120 fps are usually conformed to 23.98, 25 or 29.97 for slow motion before export.
• File too large: trim the clip, or export in H.264 at a high bit rate instead of ProRes 4444.
• Audio track: export without audio. Adobe's editing page refuses videos with audio, Shutterstock rejects added sound, music and dialogue, and Pond5 prefers audio removed.
