So I purchased a TV episode in itune store for a client wanting it for his Acting Reel and it came as a .m4v file. I tried a bunch of video converters(mpeg stream clip, hand brake, adobe encoder, emisoft video converter, clipwrap) to convert it to a different format and nothing seems to work. It either goes through with the process and gives me a blank video or it says error and doesn't recognize it. I'm trying edit it premiere cs6. Can anyone else offer a solution or have dealt with something similar?
