Custom video dimensions in iBooks Author?
I wanted my video to fit in an odd, custom dimension which appears like a vertical rectangle. I have cropped the video to the desired dimensions in pre-production using Handbrake and exported it as a m4v file. However, iBooks Author did not allow me to import the video and suggested as usual to reexport it in Quicktime in the correct format. Is there something missing from the converted video file or is it just that iBooks Author does not allow odd custom dimension videos? How can I fix this problem? I have also tried reexporting my video in Quicktime as a m4v file, but the export failed because Quicktime does not allow these custom dimension videos as well.
