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. |

Custom Matrizen die mit dem AVC Referenz Encoder kommen:
| Zitat: |
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. |

Und noch zwei von Soulhunter, ohne Beschreibung.
Dachte den ein oder anderen interessiert das vielleicht.
