HD Quick Look helps you quickly preview all your AVCHD files without actually having to play them. This can be a great time saver if you have a very large collection of AVCHD files. For those of you that may not know it AVCHD is a high definition recording format used in tapeless camcorders. Many commercial camcorders still very much use AVCHD. HD Quick Look makes use of one of Apple's latest technology previews to show you the first image of your AVCHD recording. You then quickly skip through your files until you find the one you want. Once HD Quick Look is installed, all you need to do is press Space bar on any AVCHD to bring up the preview. You can also select multiple files and view them in an index or slideshow. HD Quick Look does not actually play AVCHD files. The obvious limitation is that the first frame of a movie is at times not enough to give an idea of what it is. If you have AVCHD files on your Mac, HD Quick Look will let you preview them without playback.
