Many of the H.264 decoding tools on the market donвЂ™t properly handle these. In particular, theyвЂ™re using the вЂњhighвЂќ profile, levels 5.1 and 5.2. In large part, this is because theyвЂ™re using components of the H.264 specification that havenвЂ™t been widely adopted in the past. While Sony is making use of well-known standards like H.264 and MXF, there have been some compatibility issues with XAVC in a variety of applications. The different modes offer different capabilities, and these vary from camera to camera. In the video community, these have come to be known as XAVC-I and XAVC-L (for long-GOP or inter-frame). XAVC can also be either intra-frame or inter-frame.

And it can scale all the way from вЂњproxyвЂќ sizes (480p for example) to full 4K, and potentially beyond, at very high frame rates. It can have either 8, 10 or 12 bits per sample ( 4:4:4 and 12bit have been announced, but arenвЂ™t included in any current camera models). The H.264 format within XAVC can be either 4:2:0, 4:2:2, or 4:4:4 color sampling. For a primer on these types of compression, check out our blog posts on intraframe and interframe compression. Most of these variations appear as different вЂњprofilesвЂќ of the H.264 codec, which have different capabilities. ItвЂ™s a very capable format, which means there are many variations in use. The XAVC family ranges from very affordable pocket-friendly cameras, to very expensive shoulder-mount cameras. ItвЂ™s not вЂњXAVC inside AVCHDвЂќ or anything like that. Some of SonyвЂ™s XAVC cameras are also capable of recording the AVCHD format, but at that point, theyвЂ™re just recording AVCHD. AVCHD is usually H.264 with AC3 audio, though some cameras have extended it to use LPCM audio as well. AVCHD is a popular HD format, which normally uses the вЂњMTSвЂќ wrapper. One common area for misunderstanding is the overlap between XAVC and AVCHD.

Whether itвЂ™s MXF or MP4, the data inside the file is still H.264 and LPCM audio. This format is found in the popular Sony A7s camera.

(Other vendors use separate MXF files for audio and video.) However, thereвЂ™s one flavor of XAVC, called XAVC-S, that uses the MP4 wrapper format. XAVC generally uses the MXF wrapper, with the audio and video in a single file. Other wrappers include M2T, MXF, AVI, etc. An MOV file might contain many different types of video and audio, but the MOV part stays the same. One wrapper most people are familiar with is the QuickTime. WrappersДЄ вЂњwrapperвЂќ is the container that holds your audio and video. WeвЂ™ll get into some of the particulars of how H.264 is used within XAVC a little later. So, if youвЂ™ve got MPEG2 video or AC3 audio or any other permutation, itвЂ™s not XAVC.

XAVC is always going to involve some form of H.264 video, along with uncompressed LPCM audio. There are a few things that are constant about XAVC. WeвЂ™d like to help unravel the confusion, both from the official uses of XAVC, and some of the colloquial uses weвЂ™ve seen. XAVC encompasses a lot of different elements, and itвЂ™s created some confusion about what XAVC is, and what it isnвЂ™t. See the document: entitled Sony XAVC_SpecificationOverview_Rev2_130913.For the last few years, Sony has been shipping cameras with a new format, XAVC. This revision 2 release from Sept last I believe is the latest version. Sony's whole XAVC / XAVC-S overview was pretty well explained in their white paper release of 2013 called.

This flavor of XAVC hasnвЂ™t been put into use yet but it is expected to be made available as a firmware update to current XAVC hardware during 2014. So you still retain much of the detail but you lose motion information. There is another flavor that is very similar but it is Long-GOP. 'There are a few current flavors, or implementations, of XAVC. What your question begs is a full understanding and appreciation of what XAVC S is actually supposed to be used for.please do some read and much homework.
