|-
| Adaptive quantization, a newer feature which allows different quantizers to be used for different parts of a frame. This allows the allocation of extra bits to dark background areas to reduce blocking. (Adaptive quantization is available as a [http://akuvian.org/src/x264/x264_aq.5-654.diff separate patch] or in some [http://mirror05.x264.nl/Cef/ unofficial builds])

|-
| Adjustable scene cut detection
| ''--scenecut <integer>''
|-
| [[luma (video)|Luma]] and [[chrominance|chroma]]-based motion estimation
| ''enabled by default''
|-
| Multiple motion estimation modes: diamond, hexagon, uneven multi-hexagon, and a highly optimized exhaustive motion search
| ''--me <string> (dia, hex, umh, or esa)''
|-
| Multiple rate control modes: constant [[Quantization (image processing)|quantizer]], constant quality (CRF), single or multi-pass average bitrate (ABR) with the option of [[Video buffering verifier|VBV]] support
| ''--qp <integer>, --crf <float>, --bitrate <integer> and --pass <integer>, --vbv-maxrate <integer>, --vbv-bufsize <integer>''
|-
| [[Rate-distortion optimization]] on all frame types
