![]() ![]() Many of the H.264 decoding tools on the market don’t properly handle these. In particular, they’re using the “high” profile, levels 5.1 and 5.2. In large part, this is because they’re using components of the H.264 specification that haven’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. These are NOT implementations of the H.265 codec format. Most of these variations appear as different “profiles” of the H.264 codec, which have different capabilities. It’s a very capable format, which means there are many variations in use. The camera products implementing the XAVC codec ranges from very affordable pocket-friendly cameras to very expensive shoulder-mount cameras. ![]() It’s not “XAVC inside AVCHD” or anything like that. Some of Sony’s XAVC cameras are also capable of recording the AVCHD format, but at that point, they’re just recording AVCHD. AVCHD formatted video is usually H.264 codec generated and includes AC3 codec generated audio, though some cameras have extended it to use LPCM audio as well. AVCHD is a popular HD format, which normally uses the “MTS” wrapper. One common area for misunderstanding is the overlap between the XAVC and AVCHD codecs. Whether it’s MXF or MP4, the data inside the file is still H.264 and LPCM audio…NOT H.265 generated. This format is found in the popular Sony A7s camera. (Other vendors use separate MXF files for audio and video.) However, there’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. So, if you’ve got MPEG2 video or AC3 audio or any other permutation, it’s not XAVC codec generated. XAVC is always going to involve some form of H.264 codec video, along with uncompressed LPCM audio. There are a few things that are constant about the XAVC codec. ![]() This CODEC results in the production of a video file having a resolution of 3840x2160 (meeting the 4K criteria), formatted using H.264 standards (NOT H.265 HEVC Ultra HD standard), implements a frame rate of 29.97 fps, audio CODEC AAC (160 kbps, 48kHz Stereo), at a bit rate of 100 Mbps. They have their place.Īdobe Premiere Elements 2021 includes the use of the XAVC-S CODEC to produce their “4k Ultra HD” selected file format. XAVC and XAVC-S are good recording formats and should not be ignored. XAVC is actually an H.264/MPEG-4 AVC codec in a MXF format while XAVC-S is actually the H.264/MPEG-4 AVC codec in a MP4 format (the most commonly seen and used video format). XAVC-S and XAVC are Sony recording formats for Sony cameras. XAVC is a format that will be licensed to companies that want to make XAVC products. XAVC is a recording format that was introduced by Sony on October 30, 2012. The CODEC they use is one provided by Sony, MP-4 XAVC-S. Adobe Premiere Elements 2021, for example, includes the ability to generate a video file identified as being a 4k Ultra HD formatted file. ![]()
