The fix is to re-encode the video at a constant 30 fps, which can be done via an ffmpeg command (fps=30 filter with H.264/AAC encoding) or with a paid Mac app the author built called App Preview Converter that also handles resolution, duration trimming, and audio track requirements in one step. Other related App Store Connect app preview errors cover resolution, audio, and duration. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why does App Store Connect reject my app preview video with a frame rate error? App Store Connect only accepts app preview videos with a frame rate of 30 fps or lower, but most recording tools default to higher rates. iPhone screen recording via Control Center records at up to 60 fps, QuickTime screen recording on Mac uses a variable frame rate often around 60 fps, and Xcode Simulator recordings can also be variable, so nearly every default recording fails the requirement. _daily.dev surfaces practical fixes like this for developers wrestling with App Store submission quirks._ ### How do I convert a screen recording to 30fps for an App Store Connect app preview using ffmpeg? Use ffmpeg with the command: ffmpeg -i input.mov -filter:v fps=30 -c:v libx264 -preset slow -crf 18 -c:a aac -ar 48000 output.mp4. This forces a constant 30 fps and encodes in H.264, one of the formats App Store Connect accepts, though the video must still meet other requirements like exact resolution, 15–30 second duration, and an audio track. _Developers automating App Store submissions can find similar ffmpeg workflows on daily.dev._ ## Similar posts on daily.dev -
