This means that, in some cases, a fast Macbook Pro, Macbook Air, or iMac will outperform even a loaded Mac Pro. Because Xeons are primarily intended for use in servers, Intel doesn’t deem it necessary. The newest Intel Xeon chips, like those used in the powerhouse Mac Pro, don’t support QuickSync. This also creates some interesting disparities in performance. EditReady is able to offload a lot of the work of dealing with H.264 to this dedicated hardware, leaving your CPU free for working with non-accelerated formats like ProRes. QuickSync, now in its third generation with the Haswell architecture, provides dramatic speed increases for H.264 encoding and decoding (and some flavors of MPEG-2). To address this, they introduced their QuickSync technology with the Sandy Bridge architecture in 2011. Hardware Decodingĭue to the rise of formats like H.264 for online video delivery, Intel saw a need for better video support on mainstream computers. But, very few users are interested in buying dedicated transcoding hardware. By focusing on optimizing specific algorithms, hardware codecs are able to dramatically increase performance. Hardware acceleration for video encoding and decoding has been around for decades in the form of dedicated cards or accessories. There are a lot of operations that need to be performed on each frame of a video, and other operations that need to be performed across frame groups (GOPs). Modern formats like H.264 are able to leverage very complicated mathematical processes to minimize their space utilization. Video encoding and decoding is highly CPU-intensive. Each of these stages takes time – how much time depends on the complexity of the formats involved. Finally, you need to compress them into the new destination format. Then, you may need to do some color conversion on these frames to get them ready for the destination format. First, you need to decompress the video to raw, uncompressed frames. Transcoding a video involves a few different stages. How can it be that one application is so much faster than other applications, when they’re all doing “the same thing”? We’re going to use this post to talk about how EditReady manages to do what it does. Since launching EditReady, we’ve heard from a number of users who can’t believe just how fast it is.
