Vp9-logo-for-mediawiki.svg2014K Continues! When we last posted about the VP9 codec it was just beginning to threaten H.265 for dominance, but recent hardware partnerships with nVidia, ARM, Sony and many other tech giants solidifies VP9 as the next go-to HD and 4K streaming codec. Google’s previous VP8 codec failed to win out over H.264, which was already massively adopted by the time VP8 showed up. However, with this announcement Google looks poised to win this round of the knock-down drag out codec war. Will VP9 succeed where VP8 failed? Hit the jump to learn more. More »

WebM VP9 Video Compression CodecLet the next-gen online video compression wars begin. H.265, the codec that was approved earlier this year as an ITU-T standard and claims to be 50% more efficient than its predecessor H.264, now looks to have some competition in the Google-partnered WebM open-source V9 format, a step up from the highly adopted V8. Read on to watch some side by side comparisons and find out what this codec might do for you. More »

Sony’s tight cluster of NAB 2013 4K-centric announcements featured some of the most affordably priced UHD TVs yet seen all the way over to the external recorder-enabled 4K shooting capabilities of its FS700. The latter announcement also made it clear that Sony is looking to put a wide variety of encoding and format options into the hands of shooters — and beyond, potentially. Aside from external and third-party recording expansion, Sony is opening up its efficient 4K XAVC codec — native to the F5 family — to the consumer as well as the prosumer. Read on for some details regarding these new ‘lite’ encoding/wrapper options, dubbed XAVC S. More »

While H.265 has been approved as the next-gen lossy delivery codec, we’re still watching a vast amount of video in H.264. In fact, even when H.265 sooner or later takes its place, videomakers will still be dealing with many of the same basic compression principles at work. Knowing all the variables of a delivery encoding job can help optimize bit efficiency, ensure the highest possible quality of media, and reduce the visibility of artifacting such as banding. Read on for a look at what drives the quality-to-compression ratio of your lossy-encoded delivery video, and how you can even ‘trick’ it in some cases. More »

Technology’s progression sometimes moves with consistent momentum, and sometime comes in spurts. For instance, processors of mobile devices regularly decrease in size and price with relation to power — while, at the same time, the speed of your internet connection may not change much at all for several years, and make a great leap whenever it does. Both of these tendencies of advancement seem to inform High Efficiency Video Coding, A.K.A. H.265the successor to that other codec with which we’re all quite familiar (H.264). Improving efficiency by around double, H.265 aims to set the standard for the next decade in video streaming and encoding — and it’s going to ease mobile data congestion and likely make 4K a reality much sooner than many would have anticipated.

The advancements in lossy video encoding have been both consistent and amazing. H.264 (or AVC), that much maligned DSLR de-facto codec, sought to yield improved quality over its predecessors such as MPEG-2, all the while using half the bitrate, or lower, than such earlier codecs. Now, High Efficiency Video Coding or HEVC — likely to earn the alternate title H.265 — seeks to do the same compared to H.264, once more halving the bit rates necessary for equivalent, or even higher, quality. As it turns out, the tech world is already saturated with devices set to support HEVC playback. More »

The Panasonic GH2, arguably the most aliasing-free, highest-resolution hybrid camera out there (pictured here with the $500 ReWo GH2 cage), natively records to a 24Mbit Long GOP codec. “Long GOP” means that redundant information is retained across moving frames, which is a very efficient way of compressing video, but can also leave behind compression artifacts. In addition to the original hacked firmware by Vitaliy Kiselev, a new hacker named Driftwood has managed to drastically increase the bitrate of the GH2, in addition to switching the codec to a 176Mbit intraframe codec, which could offer even better image quality with less artifacting.
