x264 HD Benchmark 4.0

Posted on Wednesday, August 17 2011 @ 19:25:50 CEST by

Simply put, it is a reproducible measure of fast your machine can encode a short HD-quality video clip into a high quality x264 video file. It's nice because everyone running it will use the same video clip and software. The video encoder (x264.exe) reports a fairly accurate internal benchmark (in frames per second) for each pass of the video encode and it also uses multi-core processors very efficiently. All these factors make this an ideal benchmark to compare different processors and systems to each other. What's x264? It's more or less the next generation Xvid/DivX codec.

Changelog:
  • 8x8 and 4x4 adaptive spatial transform
  • Adaptive B-frame placement
  • B-frames as references / arbitrary frame order
  • CAVLC/CABAC entropy coding
  • Custom quantization matrices
  • Intra: all macroblock types (16x16, 8x8, 4x4, and PCM with all predictions)
  • Inter P: all partitions (from 16x16 down to 4x4)
  • Inter B: partitions from 16x16 down to 8x8 (including skip/direct)
  • Interlacing (MBAFF)
  • Multiple reference frames
  • Ratecontrol: constant quantizer, constant quality, single or multipass ABR, optional VBV
  • Scenecut detection
  • Spatial and temporal direct mode in B-frames, adaptive mode selection
  • Parallel encoding on multiple CPUs
  • Predictive lossless mode
  • Psy optimizations for detail retention (adaptive quantization, psy-RD, psy-trellis)
  • Zones for arbitrarily adjusting bitrate distribution
  • Program Information
