I would like to convert a 3GB MKV to something I can work with in iMovie. Usually I convert things to DV in Quicktime 7 Pro because it seems to just work. However, with this 3GB thing my Macbook wants 9 hours to do this conversion and I don't have 9 hours. My work computer is a Xeon quad-core i7 with 12GB ram (i.e. million times faster than my Macbook) and I could use it instead but it is a Windows 7-64 machine. Does anyone know of a faster or smaller file (than DV) way of getting this video into iMovie? Altenatively, does anyone know a Windows application I could use on my work computer to do this conversion of MKV into DV?
