sirber, this was discussed already and doom9 decided that there will not be an own rv forum...

but to satisfy yourself, simply see the new a/v codecs forum as rv9 forum

@ 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

kilg0r3: I rarely use fixed quality, but I think something must have gone wrong with your encode or settings, if you are seeing considerable blocking and flickering at such a high fixed quality. I have been doing some very high bitrate full anamorphic encodes with the new rate control, and those look very nice.

Thanks for the feedback, but you really need to provide some more information for it to be very useful, for instance rmeditor a few seconds of the resulting RM file and send to me, along with the job file you used.

Hm, hm, I will see, if I get around to check the encoding chain, cut out a piece and probably do some further testing. Sorry for kicking up dust.

No problem, if there is a bug, I would definitely like to fix it. Please take a look in this XviD post on how to report a potential bug: XviD: What You Must Do When Posting Bugs/Problems! Not all applies to RealVideo bugs, but much of the same information is useful for us.

Other useful tools to be aware of are the visualization support in the RealVideo 10 'Elysian' decoder DLLs. With strength set to 1 and visualizations to 2, you get a useful display when playing back the video of which quants were used for each frame. If they appear too high, compared to the fixed quality you were using, there is for instance a problem. And of course, the rv9log.txt file from the encoder, since it contains both quants and PSNR for every frame.

Thanks!

in accordance with karl_lillevold i now splitted the whole discussion behind the rv9 sticky and moved it to a separate thread
we think that it doesnt make much sense to have a 29 page long discussion as a sticky cause you are not able to find any info there you are searching for anymore anyways.
different discussion points should be discussed in extra threads and not packed into a single one

i also ask you guys for not using the rv9 sticky anymore for any discussions, the sticky should be a point where newbies can have a look at when they are searching for quick info or for the old ones which are too lazy to use search

thanks for your understanding
bond

Why not making a new forum since there is lots of threads related to RV9?

I am happy with the current state of things; I would prefer to stay in the New A/V Formats - Codecs forum, and not have a separate forum. For one, I like to keep track of everything else going on there, but I also do not think there is enough discussion on Real formats to support a whole new forum..

Code:
Describes the type of presentation (if it is audio only or 
audio and video).  This setting allows different audio streams, one 
that uses a higher bit rate for audio-only presentations and one that 
uses a lower bit rate for audio-video presentations, to be assigned 
in an audience.  The setting is used at runtime to determine what 
audio codec to use.

Default:
audio-video

Values:
audio-video, audio-only

Type:
string

Example:
<presentationType type="string">audio-video</presentationType>
I don't uderstand the codec selection thing they talk about. What if I use audio-video and I encode only audio? What if I encode video only and no audio?

Hum, if I got it right, it is this way:
You can specify four different audio codecs in an audience file:
(A) presentationType audio-video, audio mode voice
(B) presentationType audio-video, audio mode music
(C) presentationType audio-only, audio mode voice
(D) presentationType audio-only, audio mode music

If you feed the producer with an audio-only file, it will choose (C) or (D), regarding the command line option "-am <voice|music>", else (A) or (B), and will encode no audio at all (even no silence), when the source file contains no audio (but will, if the source file contains a silent audio stream).
IIRC, if you provide an incomplete audience file to the producer, it won't encode anything, but cancel with an error message.

Or am I telling you nuts you already have in your pocket?
