Be aware, a DVD or BluRay will not play back in Windows 10, Apple OS 10.7 or any OS after these. Computers are no longer sold with DVD/BluRay players and you can hardly find DVD players in stores anymore. This doesn’t necessarily mean you shouldn’t choose a DVD from us.
Choosing the right format or formats depends on your goal. If you want to be able to delete footage, re-arrange the order, add your own music, etc. then you need an editing format (see below). If you simply want to archive the film and be able to easily view it, then MP4, DVD or BluRay is the best format.
So, there are viewing formats and editing formats and you can have both! You can specify up to 3 different formats on the order form. So. if you want a few formats like MP4 and DVD and then an editing format like HD-AVI or HD-ProRes you can do that.
