I retain copies of all the edited files (everything necessary to make new DVDs). DVDs can sometimes quit working or get damaged, etc. I will replace any DVDs as needed. I also will keep the on-demand site and the highlight video link available indefinitely. I don't retain copies of raw footage after a certain point (about 1 month after the final product is delivered) so if you need changes made that involve editing the actual video, this should be requested right away. So in short I do provide support after the product is delivered, I try to do this as quickly as possible after I get your request.
