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:
- CAVLC/CABAC

- Intra: all macroblock types (16×16, 8×8, and 4×4 with all predictions)
- Inter P: all partitions (from 16×16 down to 4×4)
- Inter B: partitions from 16×16 down to 8×8 (including skip/direct)
- Ratecontrol: optional VBV, single or multipass ABR, constant quantizer
- Scene cut detection
- Adaptive B-frame placement
- B-frames as references / arbitrary frame order
- 8×8 and 4×4 adaptive spatial transform
- Lossless mode
- Custom quantization matrices
- Parallel encoding of multiple slices
