But the codec needs a stressed advanced mathematical function to make this technique really useful. 265 High-resolution videos is significant this can mean a big difference between hardware and software implementations of H. And given the compute effort required to encode and decode H. Improve subme7 at low QPs and add subme7 support in lossless mode.Our trademarks websites apps products services and technologies services are provided by the companies listed in section 13 below.This change may decrease bitrate in VBV mode, but that is preferable to the artifacting produced by this code.This code seemed to act up unexpectedly sometimes, creating a situation where in 1-pass VBV mode, a frame's quantizer would drop all the way to qpmin and then shoot back upwards to qpmax, causing serious visual issues.Prevent VBV from lowering quantizer too much.Zones for arbitrarily adjusting bitrate distribution.Psy optimizations for detail retention (adaptive quantization, psy-RD, psy-trellis).Spatial and temporal direct mode in B-frames, adaptive mode selection.Ratecontrol: constant quantizer, constant quality, single or multipass ABR, optional VBV.Inter B: partitions from 16x16 down to 8x8 (including skip/direct).

Inter P: all partitions (from 16x16 down to 4x4).Intra: all macroblock types (16x16, 8x8, 4x4, and PCM with all predictions).B-frames as references / arbitrary frame order.It is widely used by television broadcasters and ISPs.

x264 forms the core of many web video services, such as YouTube, Facebook, Vimeo, and Hulu.

Support features necessary for many different applications, such as television broadcast, Blu-ray low-latency video applications, and web video.

Gives the best quality, having the most advanced psychovisual optimizations.

Achieves dramatic performance, encoding 4 or more 1080p streams in real-time on a single consumer-level computer.

Provides best-in-class performance, compression, and features.

X264 is a free software library and application for encoding video streams into the H.264/MPEG-4 AVC compression format, and is released under the terms of the GNU GPL.
