You’d think, wouldn’t you, that in this day and age such things were universal but sadly not. Android phones and iPhones often have different recomended aspect ratios. Without going through every single one, I would simply say this; Know where the film is going before you begin and your production company will be able to advise you about which format and aspect ratio to use. If you neglect this step it will cause you problems at the end of the project, and most likely lead to a falling out with the post-production team. It is a particular bugbear of theirs, take it from one who knows!
