Consider the location. It is always more convenient if you have a provider to make the conversion living in your town or city, as it means the whole process will be faster for you.
Consider how many films you have to convert. If you have a lot of film, many providers will offer a discount. Sunray Video, for example, offered a one-day, 10 percent discount in January 2011, for orders over 1,500 feet of film.
Consider whether you want any other format for your film, other than DVD. A company such as FilmFix offers to transfer the film to MiniDV as well as a hard drive.
Check the testimonials of the conversion provider, especially if that company is not local to you. You are trusting someone with your prized film, so it is important to make sure other customers have been satisfied with that service. Research the company online before you buy its service straight away.
