At a Loss with Video Compression? Here Are Some Encoding Basics and Artifact Removal Tutorials

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 »

H.265 is Now Officially Approved, is 4K Streaming and Broadcast Just Around the Corner?

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.265 — the 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 Future of Encoding is Almost Here: HEVC (H.265) is Coming to 1 Billion Devices

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 »
