EQM AVC-HR rev.1 This matrix was made for medium-high bitrate backups with High-Profile AVC encoders that support custom matrices and 8x8 discrete cosine transform. It also reduces blocking. Usage: - high quality backups of DVD material at full resolution (anamorphic) and bitrates of at least 1300-1400kbps (for average motion and not noisy/old movies). - non anamorphic/vertically resized encodes at bitrates of at least 1000kbps. |

jvt the jvt matrix, used as the default custom matrix by the avc reference software (comparable to the "mpeg" matrix of mpeg-4 asp), uses the same values in all intra4x4 matrices and the same values in all inter4x4 matrices. q_matrix the "q_matrix", coming with the avc reference software, uses the same values in all intra4x4 matrices and the same values in all inter4x4 matrices. q_matrix2 the "q_matrix2", coming with the avc reference software, uses the same values in all intra4x4 matrices and the same values in all inter4x4 matrices. flat 16 not really a custom matrix, as its the matrix thats used when no custom quantisation matrix is used, but still listed for completeness. |

High Bitrate Matrix Depending on your tastes, you'll need atleast 1000kbit/s. That's approx the average bitrate I got with a clean source, that had a mix of fast and slow motion scenes at --crf 20. Fast and fairly intense chapter 20 from star wars ep. 3, required 3200 kbit/s at --crf 20. Almost forgot, the source was resized to (576,240) General matrix I would class this a low to medium bitrate matrix. Tested against Sharktooth's excellent EQM_AVC matrix, it produces better SSIM at bitrates around 700 kbit/s. |

Hast Du die o.g. schon mal näher angeschaut, also qualitätsmäßig? |
