The report only includes the one preset that gives the best quality for each encoder. see post #25 for a comparison that includes VCE i7-6700k with GTX 1070 (QSV_Skylake with NVENC_Pascal) i5-3570k with GTX 670 (QSV_IvyBridge with NVENC_Kepler) This is the result for OBS simple settings for streaming. The first level of comparison was made with ffmpeg (method see down below). Then I compared the quality of the resulting videos to the original lossless recording. So I made a autohotkey script and created recordings of literally every combination of every encoder setting. There are so many configuration options and there is so many different hardware available, so this is always very difficult to answer. If I use a hardware encoder, does the quality suffer? H.265 encoding.What encoder and which encoder setting should I use for streaming/for recording? The table below compares the recommended bandwidth for H.264 vs. This also enables the streaming of 4K video over common network speeds.īecause H.265 compresses your data so much more efficiently, using it as your video compression tool will drop your bandwidth and storage requirements by roughly 50%. Fortunately, however, it also means that viewers with H.265 compatible devices will require less bandwidth and processing power to decompress that data and watch a high-quality stream. This means that HEVC requires more advanced hardware, such as the BoxCaster Pro, to be able to compress the data.
In addition to the larger CTU sizes, HEVC also has better motion compensation and spatial prediction than AVC does.
If you want to learn more about HEVC's impact, check out this post. Whereas macroblocks can span 4x4 to 16x16 block sizes, CTUs can process as many as 64圆4 blocks, giving it the ability to compress information more efficiently. Unlike H.264 macroblocks, H.265 processes information in what’s called coding tree units (CTUs). The main difference is that HEVC allows for further reduced file size, and therefore reduced required bandwidth, of your live video streams. H.265 is more advanced than H.264 in several ways. While that might sound confusing, here’s what you need to know: The H.264 algorithm can substantially lower bitrates better than previous standards, and is widely used by streaming internet sources like Vimeo, YouTube, iTunes, and more. Macroblocks (see image below) typically consist of 16x16 pixel samples that can be subdivided into transform blocks, and may be further subdivided into what are known as prediction blocks. It works by processing frames of video using a block-oriented, motion-compensation-based video compression standard. H.264 (also called AVC, or Advanced Video Coding) is an industry standard for video compression that allows for the recording, compression, and distribution of digital video content. In this post, we compare H.265 to its predecessor, H.264, and explore what H.265 means for your live broadcasts. Recent technology known as H.265 (also called HEVC, or High Efficiency Video Coding) has emerged to combat this issue. No matter what you’re watching, this abrupt loss of quality is incredibly frustrating. We’ve all been there: watching an online video, movie, or sporting event when suddenly, the screen freezes up, or the quality isn't what it previously was.
