RV9 encoding questions

[jkwarras]

HI,

I have some question sabout RV9 encoding. I've just donde my first RV9 DVDRip, it was "Akira". I must admit that the output was great at my surprise since i've always use DivX/XviD, and i didn't think that RV9 could deliver such a good quality. I did a version of a scene qith XviD/DivX and with RV9 (EHQ high), and the winner was no doubt RV9: no blocks, no smearing, beautiful, really. XviD and DivX, with exactly same avs (i was using the QMF function posted in Avisynth forum) and same settings (1 bframes, GMC, VHQ (for XviD), blablabla) was lots of macroblocks and smearing. Bitrate target: 743 kbps.

But i must admit i don't know anything about rv9. I've been reading alot of threads in this forum, and download several Guis for helix producer, but it seems to me that the infromation is not grouped, and i have some little questions that maybe some one can help me out:

1) Does RV9 use bframes? I think that isn't the case but i've read in one of threads here that it use this.

2) 1 pass VBR is really much worst that 2 pass VBR? Encoding time is reaaly sloooow, for a 1 pass VBR it tooks on my Pentium III 800Mhz 320 Ram, 25 Hours, and waiting 2 days for a 2 pass vbr encoding is a little overkill for me. The result was really good with 1 pass VBR. I also tried a 2 pass XVID, and the results for same size was really worst.

3) Is RV9 only good for animes? I'm going to do some test in a Harry POtter trailer, see the results on "real" action.

4) What's the best and complete RV9 gui for producer? I haven't found one with all the options mentioned over threads around here: EHQ, Dropdude, (bframes?)... HPG have EHQ but not dropdude, realanime has dropdude but not EHQ, etc... Or am i too stupid to don't see this options? (can be, no doubt :D )

Sorry, don't hit me because of my "newbie" questions. I'm so used to XviD that RV9 seems like martians to me ;)

1) RV9 uses 0, 1 or 3 b-frames.

2) 1-pass VBR is supposed to give less quality. Use 2-pass VBR or 1 pass Constant Quality (for animes :D)

3) RV9 is also good for real movies. The only thing RV9 don't like is rain. I think Karl don't like rain also... ;)

4) Right now the most complete GUI is AutoRV9, then RMFactory 2. In some weeks, my Surreal UI might be out :D. SUI will also supports major VFW codecs.

But can we decide about that? I mean can we define the amount of bframes that the encode must use (like XviD) or does the codec handle that internaly?

I know it delivers worst quality, but i don't know if its really deserves the EXTRA time (my computer is too slow for that, if it wasn't of course i wouldn't doubt :D). As karl_lillevold reported in this thread http://forum.doom9.org/showthread.php?threadid=64163 2 pass delivers a MIn PSNR of 3.66db higher than 1 pass vbr, but the AVGPSNR is quite the same. So i guess slow motion parts will get worst.

I also don't like rain, i live in Belgium man ;) I will try to encode some real action.

That will be cool.

Another question: What do I have to do in order to play RV9 in Matroska container stored in an XCD? I know i have to install a plugin (dll) but don't know the exact way to do it.

Please see the Undocumented RV9 tweaks (http://forum.doom9.org/showthread.php?s=&threadid=60712) thread. Default is adaptive, but it's possible to tweak.

AutoRV9 and RMFactory are french Gui ... ;)

Vive la France et la Belgique aussi ... :D
