  • How to get iOS App Preview video bitrate in range

    29 avril 2019, par JKaz

    Creating new App Previews for App Store Connect has always been difficult. Time to do it again (new app version) and running into same issue without resolution this time.

    Making the video is easy enough, recording it with Quicktime and either a connected device or through Simulator (and the xcrun simctl io booted recordVideo <filename>.<file extension="extension"></file></filename> Terminal command).

    I can open that in iMovie, create a new App Preview, and export/share the preview with proper size, length, frame rate per Apple specs. But the bit rate is always too low ( 4 mbps) and it’s required to be 10-12 mbps (and I’ve had video reject be/c of that). In the past I could always make some change to the .mp4, in conjunction with something like ffmpeg -i ~/appVideo.mp4 -b:v 11M ~/appPreview.mp4 to get the file into the target range, but that’s not helping today, and neither is Developer Tech Support.

    Apple’s documentation says :

    To export the final video, click Share in the toolbar, then choose App
    Preview. The export settings are automatically configured to meet App
    Store requirements. iMovie exports the final video at the correct
    resolution based on the device from which your clips were captured.

    I’ve done that and more, and bit rate is still out of range (every other attribute is in spec). I’ve tried the recommendations from a bunch of other threads here for http://video.online-convert.com/convert-to-mp4 and others, and none seem to do the trick. Am I missing something obvious re bitrate ? Is it this hard for everyone ?

    Thank you.

  • How to set yuv to full range in a mpeg2video ?

    7 mai 2021, par Jefferson Villasan Josol

    I've found out that YUV420P has a limited range based on MediaInfo. How can I set that into Full range using ffmpeg ? Does anyone know how to set it into Full ?&#xA;I'm currently using mpeg2video -q:v 0 because it has an acceptable quality and small file sizes compared to x264 -crf 0.&#xA;Thanks in advance for those who can help me !

    &#xA;

    Edit : I prefer mpeg2video because it is much faster compared to x264 encoding. And I've also noticed that -q:v 0 is better than -q:v 2. I don't know if it sounds strange but on my phone, the quality is really better if I use the -c:v mpeg2video -q:v 0
