A YouTube video cutter must be versatile enough to be compatible with all devices and all operating software, i.e., iOS, Android, Mac, and Windows. You should be able to resume your work right from where you left off, and device compatibility shouldn't limit your endeavor. Moreover, a YouTube video cutter should support all formats, such as MP4, MOV, AVI, WMV, FLV, WebM, and AVCHD. If you are a professional content creator, you will deal with all sorts of video formats. If your YouTube video cutter is exclusive to a few video formats; you'll have to put in the extra effort to convert it to a compatible format through another application.
