App store allows you to upload app preview videos.
It says here…
But the ratio/screen size matches no standard output of any video editor I’m familiar with.
You get 30 seconds to show something useful.
After a lot (a lot!) of messing about with ‘incorrect size’ messages, I managed to create a 27 second 1200 x 900 pixel video and tried that - only to be told that H264 format was ‘too high’ , Even though Apples’ guidelines suggest a suitable screen size is 4 x this, and H264 is expected.
If you have succeeded, what did you use to create it and what kind of settings did you really need to use?
