How it works
- App Review Information Notes allow up to 4000 bytes, and a reply to App Review allows 4000 characters with optional file attachment. The fetched pages state no attachment file-type list, per-file size cap or file count. Treat the video as a supplement and describe the flow in text.

Measurements and reference values
- Apple's published codec, size and length limits (H.264 High Profile Level 4.0 at 10-12 Mbps or ProRes 422 HQ; .mov/.m4v/.mp4; 500 MB; 15-30 s; Mac previews 1920x1080 landscape) are for App Store app previews. They are not documented as limits for App Review attachments, so they are a safe conservative target but not a rule. (low confidence) (verified as of 2026-10-02) [source]
Facts and statements
- On macOS, Shift-Command-5 opens the Screenshot tool with record-entire-screen, record-window and record-portion options. Recordings save as .mov files named 'Screen Recording <date/time>'. Options include microphone choice, timer, mouse pointer visibility, and an HDR or SDR capture format. (low confidence) (verified as of 2026-10-02) [source]
- Developers reported failed review-attachment uploads in App Store Connect (thread from March 2024). Renaming .MP4 to lowercase .mp4 fixed one case. Wrapping the file in a .zip fixed another. Rename to lowercase and zip are practical fallbacks. (low confidence) (verified as of 2026-10-02) [source]
- App Review's own forum tips say to put hardware-related demonstrations in the Notes field of the version's App Review Information. For hardware integration it asks for a video of the real hardware plus the app on a physical device, not only a screen recording. A network monitor needs no accessory, so a screen recording suffices. (low confidence) [source]
- Attach the recording to App Review Information or the reply as the default, so the reviewer needs no external access and the evidence stays with the submission. Use a link only if the upload fails or the file is too large, and then prefer a long-lived unlisted URL over an expiring share link, with the access note in Notes. This is inference from the documented 4000-byte Notes and attach-file support, not an Apple rule. (low confidence) [source]
