@ karl

it really is a shame that I do not have time to do proper tests. Anyway, I just wanted to let you know. I have been doing some encodes of the Potter Trailer at full resolution and ultra high bitrates, ie. vbr constant quality 82-90. I am sorry to say that IMHO Rv10 underperformed xvid and Vp6 showing considerable blocking and flickering. The listed settings below do not exhibit the correct syntax because I put in the alternative values. The audience file looked different of course

<encoderComplexity type="uint">85</encoderComplexity> <enableAutoKeyFrames type="bool">true</enableAutoKeyFrames> <maxConsecutiveBFrames type="uint">0,1,3</maxConsecutiveBFrames> <exactPreview type="bool">true,false</exactPreview> <inloopCutOffQuant type="uint">1 or 12</inloopCutOffQuant> <inloopCutOffCompatible type="bool">always false</inloopCutOffCompatible> <inloopCutOffBUseRefQuant type="bool">always false</inloopCutOffBUseRefQuant>

<encodingType type="string">vbrQuality</encodingType> <quality type="uint">82,85,90</quality>


Properties of one example clip extracted with rmvbext:

Stream number : 0
Maximum bitrate : 47263000 bits/s
Average bitrate : 2417851 bits/s
Maximum packet size : 16009 bytes
Average packet size : 5872 bytes
Time offset : 0 ms ( 00:00:00.0 )
Prebuffering : 1037 ms ( 00:00:01.037 )
Duration : 122960 ms ( 00:02:02.960 )
Stream name : Video Stream
MIME type : video/x-pn-realvideo
Video resolution : 688x428

I suspect that Rv10, understandably, might not be optimised for Dvd-like bitrates.

Cheers, kilg0r3
