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. Still though)īoth machines running windows 10, premiere 2018.Īdobe Premiere Elements 2021, for example, includes the ability to generate a video file identified as being a 4k Ultra HD formatted file. Its ghetto, but it works, and I swear H265 uploads look slightly better on youtube and facebook (I do understand FB/YT are re-rendering these, probably to H264. Does it refer to the CPU? Does my laptop CPU have some H265 feature that premiere can take advantage of? Has anyone else experienced this? My current workflow is to render a flattened DNxHR444 file out of my desktop, and encode that to H265 on my laptop. So I guess my question is- what does the HEVC hardware encoding option refer to, and why isn't it available on my desktop? It can’t be the GPU, as you can see both machines have an awesome 10-series Nvidia, with the desktop rocking the 1080 Ti. I’ve done UHD DNxHR files slightly slower than real time, no problem. ![]() On my laptop however, when choosing the hardware encoding option and highest quality setting, it hums along like any other encoding option. (I should mention I have the quality selection, which defaults at “good”, all the way up to “highest…because come on, who doesn’t want the highest possible quality) Shortly after starting, it gets to be several seconds PER FRAME. Like, to encode a 3 minute 1080 DNxHR file seems to take something like 45 theoretical hours. On my desktop, the hardware encoding option is grayed out, forcing one to choose software. ![]() This is separate from the Mercury playback engine. If you didn’t know, when choosing H265 (HEVC) one has the option of using software or hardware encoding. ![]() Weirdly there is one thing my laptop can do that my desktop cannot, which is the HEVC H.265 encoding option. Generally taken everything I’ve thrown at it. The desktop machine has been pretty awesome for the past 3 or so years. I have a solid desktop workstation at work, and a reasonably powerful laptop.
