So you certainly don't want to tinker with the film spools. You can simply buy them if you don't have any. However, a 5-inch empty spool is already included in the delivery. On YouTube there are countless videos of this and similar products, which are probably all identical, only with a different branding/brand name. For example, the following video:

For post-production and video editing in general, the usual video editing programmes (Adobe Premiere, Sony Vegas, DaVinci Resolve, etc) are recommended. Of course there are also freeware programmes on the net, just google "video editing Windows (or Mac)".
