It will have all the codec information there.Īdditionally, on Windows there is a small utility called G-SPOT which can show you what codec are you using on that file etc. More tips: if you're not sure what codec a file is in, you can open it in QuickTime and hit cmd+i to open the inspector window. Be sure to save the ENTIRE folder structure from your memory card, not just the mts, mxf, or whatever files. not mov, mpeg, mp4), you will need to use a transfer process in your NLE. One other note: if your camcorder saves files in a weird format (ie. BluRay videos are actually encoded in an ultra high quality H.264 It is supported nearly universally and is very good quality with relatively small files. The more compressed it is the more the computer has to work to decode and re-enconde the information when you make changes (moving on the time line, cutting, adding effects etc.)įor recording and editing (HD), pick a low compression, high quality codec such as DVCProHD, AVCHD, Apple ProRes. Also, most pro level NLEs (like Final Cut Pro (not FCPX)) play nicer with codecs that are less compressed. ![]() The more compressed a codec is, the smaller your files will be, but they will also potentially be losing information, in the same way that a RAW file saves everything from CCD, and JPEG compresses the file by dropping repeated information. Codecs come with varying degrees of compression. This is due (in part) to corporate/organizational pissing contests (or format wars - remember dvd+ vs. Some file formats only work with certain codecs. The video information is encoded in a codec (Coder/Decoder). File formats are essentially wrappers, a container of sorts. ![]()
