AVC-Intra defines two classes: •AVC-Intra 50: •AVC-Intra 100: •nominally 50 Mbit/s, size of each frame is fixed •nominally 100 Mbit/s, size of each frame is fixed •CABAC entropy coding only. •CAVLC entropy coding only. •1920 × 1080 formats are High 10 Intra Profile, •All formats are High 4:2:2 Intra Profile, Level Level 4 4.1 •1280 × 720 formats are High 10 Intra Profile, Level •4:2:2 chrominance sampling 3.2 •frames are not scaled •4:2:0 chrominance sampling Common to both classes; frames are horizontally scaled by 3/4 (1920x1080 is • •Frame rates: 1920 × 1080 (23.98p / 25p / scaled to 1440x1080. 1280 × 720 is scaled to 29.97p / 50i / 59.94i), 1280 × 720 (23.98p / 25p / 960x720) 29.97p / 50p / 59.94p) •10 bit luma and chroma Video High Definition Standard Definition Subtype (AVCHD-HD) (AVCHD-SD) 1920×1080 Frame size in pixels 1280×720 720×480 720×576 1440×1080 29.97, interlaced 59.94, progressive 25, interlaced 50, progressive 29.97, Frame rate 25, interlaced 23.976, 23.976, interlaced progressive progressive Frame aspect ratio 16:9 4:3, 16:9 Video Compression MPEG-4 AVC/H.264 Luminance sampling 74.25 MHz 74.25 MHz 13.5 MHz 13.5 MHz frequency 55.7 MHz Chroma sampling format 4:2:0 Quantization 8 bits (both luminance and chrominance) Audio (Dolby Digital) AC-3 Compression Dolby Digital (AC-3) AC-3 channel mode 1-5.1 channels AC-3 compressed bitstream 64 to 640 kbit/s rate Audio (PCM) PCM linear PCM uncompressed audio PCM channel mode 1-7.1 channels PCM bitrate 1.5 Mbit/s (2 channels) System Stream type MPEG transport stream up to 18 Mbit/s (DVD media) System data rate up to 24 Mbit/s (all other media) File extension (generally) mts (on camcorder), m2ts (after import to computer) 8 cm optical media (DVD) SD/SDHC/SDXC Memory Card Media "Memory Stick" Built-in hard-disk or flash Media Specification addendum (AVCHD 2.0) The AVCHD 2.0 format includes video compression with H.264 Main Profile (MP) and High Profile (HP) up to H.264 Level 4.2 AVCHD 2.0 adds support for the following recording modes: Video Subtype AVCHD Progressive AVCHD 3D (stereoscopic) Frame size in pixels 1440×1080 1920×1080 1280×720 1920×1080 23.976, progressive 59.94, progressive 59.94, progressive Frame rate 25, interlaced 50, progressive 50, progressive 29.97, interlaced Frame aspect ratio 16:9 Video Compression MPEG-4 AVC/H.264 Luminance sampling frequency 111.4 MHz 148.5 MHz 74.25 MHz Chroma sampling format 4:2:0 Quantization 8 bits (both luminance and chrominance) Audio (Dolby Digital) AC-3 Compression Dolby Digital (AC-3) AC-3 channel mode 1-5.1 channels AC-3 compressed bitstream rate 64 to 640 kbit/s Audio (PCM) PCM linear PCM uncompressed audio PCM channel mode 1-7.1 channels PCM bitrate 1.5 Mbit/s (2 channels) System Stream type MPEG transport stream System data rate up to 28 Mbit/s File extension (generally) mts (on camcorder), m2ts (after import to computer) SD/SDHC/SDXC Memory Card Media "Memory Stick" Built-in hard-disk or flash Media.
