Network Programming in .NET

iMovie is a simple and intuitive app for creating AppPreview videos, but, what’s really annoying is that it only creates appPreview videos compatible with 4 inch iPhone displays – Like the iPhone 5s ? – really old.

You really need to have videos for the iPhone 6s, and 6 Plus. But before you buy QuickTime Pro, here’s a free way.

EasyWMV’s demo version is limited to 1 minute of video, but that’s fine for App Previews, which are only 30 seconds anyway. Now, you need to fiddle with the settings.

For the iPhone 6 Plus (5.5 inch), I selected Custom size – 1080×1920.

Deselect “Preserve aspect ratio”

Drop the bit rate down below 1200kbps.

Now for the techy stuff, how I diagnosed this – I uploaded a video with the bit rate too high, and got a vague warning from iTunes Connect. I then looked in inspector for more details and saw this:

{
“statusCode” : 400,
“errorCodes” : [ “MOV_H264_LEVEL_TOO_HIGH”, “MOV_VIDEOCODEC_NOT_ACCEPTABLE_FOR_VIDEOTYPE” ],
“suggestionCode” : “MOV_RESAVE_LOWER_LEVEL”,
“nonLocalizedMessage” : “H264 Level is too high. Please refer to Apple’s documentation for appropriate levels.”,
“localizedMessage” : “The H264 Level is too high. Please refer to Apple’s documentation for appropriate formats.”
}

Which according to apple, this is the maximum specs:

And 12Mbps translates to 12000 Kbps

Then you get this a success in the trace once it works:
