What resolution should App Store preview videos be?

Each device has a specific resolution. iPhone 6.9" uses 886×1920 (portrait) or 1920×886 (landscape). iPhone 5.5" uses 1080×1920. iPad 13" uses 1200×1600. Mac and Apple TV use 1920×1080. Vision Pro uses 3840×2160.

What codec and format do App Store preview videos require?

H.264 High Profile (up to Level 4.0) or ProRes 422 HQ. Max 30fps, AAC stereo audio at 44.1 or 48 kHz, 256 kbps. Accepted containers: .mp4, .mov, .m4v. Duration must be 15–30 seconds. Color space must be YUV 4:2:0 (yuv420p).

Why does App Store Connect reject my preview video?

Common reasons include wrong pixel dimensions for the target device, variable frame rate (screen recordings are often VFR), missing or incorrect audio codec (must be AAC stereo), using H.265/HEVC instead of H.264, or video duration outside the 15–30 second range.

Do I need separate preview videos for each device size?

Yes. Apple requires a separate preview video at the exact pixel dimensions for each device display size you support. Some sizes cover multiple devices — for example, the 6.9" iPhone spec also covers 6.5", 6.3", and 6.1" displays.

Can I use HEVC or H.265 for App Store preview videos?

No. App Store Connect accepts H.264 High Profile or ProRes 422 HQ only. H.265/HEVC, VP9, AV1, and other codecs are rejected. iOS and macOS screen recordings often default to HEVC, so they must be re-encoded before uploading.

Video codec

Apple accepts H.264 High Profile (up to Level 4.0) or ProRes 422 HQ. Baseline, Main profile, H.265/HEVC, VP9, and AV1 are all rejected. Screen recordings from iOS and macOS often default to HEVC or variable frame rates, both of which are rejected.

Audio track

An audio track must be present even if the video has no sound. A silent stereo AAC track satisfies the requirement. Mono audio, surround sound, or a missing audio stream all cause rejection. Sample rate can be 44.1 kHz or 48 kHz.

Duration & container

Duration must be 15–30 seconds. Shorter videos can be padded by freezing the last frame. Longer ones must be trimmed. The faststart flag moves the moov atom to the front of the file for streaming compatibility.

Why App Store Connect Rejects Previews

Apple doesn't always explain why a preview was rejected. These are the most common technical causes.

Wrong pixel dimensions

Must be the exact resolution for the target device — not the native screen recording size

Variable frame rate (VFR)

iOS screen recordings use VFR — must be re-encoded to constant 30 fps

Wrong codec (H.265/HEVC)

Only H.264 High Profile is accepted — HEVC, VP9, AV1 are all rejected

Missing or wrong audio

Must have AAC stereo at 48 kHz — mono, missing, or non-AAC audio is rejected

Duration out of range

Must be between 15 and 30 seconds — shorter videos need frame padding, longer need trimming

No faststart flag

The .mp4 moov atom must be at the start of the file — without it, App Store Connect can't stream the preview
