x264 Video Codec is a free application for encoding video streams into the H.264/MPEG-4 AVC format.

MPEG-4 is a broad Open Standard developed by the Moving Picture Experts Group (MPEG), a working group of the International Organization for Standardization (ISO) which also did the well-known MPEG-1 (MP3, VCD) and MPEG-2 (DVD, SVCD) Standards, standardizing all sorts of audio/video compression formats and much more

By its nature, the MPEG-4 Standard doesn’t aim at standardizing one potential product (e.g., something comparable to DVD) but covers a broad range of Sub-Standards, which Product Providers can choose from to follow, according to what they need for their product.

The AVC/H.264 standard defines four different Profiles: Baseline, Main, Extended and High Profile:

  • Baseline Profile offers I/P-Frames, supports progressive and CAVLC only
  • Extended Profile offers I/P/B/SP/SI-Frames, supports progressive and CAVLC only
  • Main Profile offers I/P/B-Frames, supports progressive and interlaced, and offers CAVLC or CABAC
  • High Profile (aka FRExt) adds to Main Profile: 8×8 Intra prediction, custom quants, lossless video coding, more yuv formats (4:4:4…)x264 Video Codec Features:
