Announcements in the App Store for iPhone X not working with iMovie?

Question

I'm trying to provide a preview of the video for the App Store for my iPhone X application, but when I exported it from iMovie, it exports to the size of iPhone 6, not X. When I tried to download to iTunes Connect, it said: this is the wrong size. I do not know if iMovie does not support X yet, or if this is an error?

And is there a way to resize the video frame so that I can upload it? Thank!

Answer 1

Unfortunately, iMovie does not yet support iPhone X. You can try resizing the exported video as:

 ffmpeg -i filename.mp4 -strict -2 -vf scale=1080:1920 -ac 2 output_file.mp4
