Helix Producer最新版包含了一個超高品質模式，要此模式不是輕易可以使用的，強烈建議使用前先看看討論區內的相關資訊
The Helix Producer 9.2 June 4th *) build includes an EHQ mode that I am happy with. You can get it here:
https://distribution.helixcommunity...st?folderID=130Remember that after signing up, you have to agree to the RPSL (or RCSL) license and also the Binary EULA before you can download it.
*) please delete ralf.dll from the codecs folder in this build, since it causes problems for rmeditor.
In many cases a quality improvement corresponding to a 30% bitrate reduction can be seen compared with standard RV9, and this is with a fully backwards compatible bitstream.
As you may know, PSNR measurements are the most commonly used indication of compression efficiency for video codecs. Compared with for instance VSS H.264 codec in its best quality mode, RV9-EHQ has higher compression efficiency, and encodes 25X faster.
encoderComplexity sets the EHQ level:
65 = Default : improved efficiency for high action
70 = High : same as 65 + better mode decisions, better representation of high motion
80 = Extra High: same as 70 + best possible mode decisions, very high accuracy motion representation
50 = Fast : not recommended, use only for Live capture encoding
簡單說--------
RMVB品質提升30%
比目前最棒的H.264速度快25X
EHQ模式而言:
65是預設就比原來好了
80是極佳但要花費3-4X時間
