I don't want to waste bitrate or quality or media. For example the problem is find out how many episodes of a series do fit in a DVD5, with a transparent (or close to it) quality and then encode targeting the DVD5 size or to align the encoded size of a movie to a DVD5/4 units. Anyway, back on topic, I already do what you suggested on non-Psy builds, but it seems that I cannot balance it on "psy Rdo" builds. I don't have a starting point and numbers don't mean much any more. Must be something I am missing. Thanks |

Find out which CRF value still gives acceptable quality for you. Then encode all your episodes with that CRF value.
Finally put as many episodes on the disc, as fit on the disc. That's it...

Is "Turbo" in MeGUI a good option to use with PsyRDO?
Will it affect the quality significantly? Some posts here mention that settings need to be the same on both passes.

Turbo option just speeds up the first pass.
it does it using different (lower) settings than the second pass. that means a very slight final quality loss but a huge gain in first pass speed.

Only Trellis=1 is disabled when Psy RDO is on, Trellis=2 works just fine with Psy RDO ...

I've encoded full STEM clip at 15 MBits/s using this patch and Sonic CineVision 2.6. Sonic's encode is consistently better, am I doing something wrong or commercial encoders are not as crappy as some x264 apologists claim?
Here's the command line: x264.910.modified.exe --pass 1 --fps 23.976 --bitrate 15000 --level 4.1 --keyint 24 --min-keyint 1 --ref 3 --mixed-refs --no-fast-pskip --bframes 2 --b-pyramid --bime --weightb --filter -2,-2 --subme 6 --analyse p8x8,b8x8,i4x4,i8x8 --8x8dct --vbv-bufsize 45000 --vbv-maxrate 30000 --threads auto --thread-input --progress --no-dct-decimate --output "f:\stem_x264.264" "F:\Source Files\StEM_full.yuv" 1920x1080 --aq-mode 2 Second's pass settings are the same, but with --pass 2. I can post some pictures if anyone is interested |

why did you use min-keyint 1 and keyint 24, only 2 b-frames, filter -2,-2, VBV limits, etc?
however look at the comparisons x264 is way better than commercial encoders.

laugh whenever you want. you're a n00b and not even able to set up an encoder correctly and you're still talkin? get out or learn something before speaking.
and, yes, it's a fair comparison made by competent ppl, not incompetent ppl like you. x264 also won the last doom9 codec comparison... so better SEARCH before speaking as per forum rules. if you came here for insulting the devs hard work then you're NOT welcome.

Sharktooth : VBV & gop restriction come probably from Bluray constraints, so he can't avoid them. And imho, you're overreacting (and that's an understatement)
Vit : I don't remember Bluray preventing you from using 3 bframes in a row. And VBV bufsize, iirc, is half a second, thus 15000, not 45000.

1. You use awful settings and wonder why the output sucks (sorry folks, but I'm not going to make x264 compensate for user stupidity here). 2. Instead of asking "how can I make these settings better", you start whining about "x264 apologists"... Now, if what you actually meant was "How can I improve the quality of my output" and you just mistyped, try this instead: x264.910.modified.exe --pass 1 --fps 23.976 --bitrate 15000 --level 4.1 --ref 4 --mixed-refs --no-fast-pskip --bframes 3 --b-pyramid --me umh --mixed-refs --bime --weightb --filter -2,-2 --subme 7 --b-rdo --8x8dct --threads auto --progress --no-dct-decimate --output "f:\stem_x264.264" "F:\Source Files\StEM_full.yuv" 1920x1080 15 megabit 1080p is a rather bad place to compare at though, given that any decent encoder should be able to basically give transparency, and if you can't pick out the details between two encodes without using a microscope, its hard to compare them.

Though, VIT Sharktooth is right, x264 when given the proper settings is a miracle worker. Try the settings that he gave you and see if there is any improvement. |

- Any screenshots and the details of the settings you used in CineVision to share ?
- CineVision isn't the only commercial encoder out there, so maybe you are right and it might well be better than other commercial encoders, but those have indeed been proven weaker than x264, you can't deny it. But the former also needs proving with pictures or samples Quote:

he could also use 3 bframes (it's ok with blu-ray and could give a major boost in quality), eliminate --no-dct-decimate (that often results in bigger filesize hence worse quality for a bitrate based RC) and --no-fast-pskip, higher the deblocking (-2,-2 often means blocks), -b-rdo and -me umh are missing but he used other useless slow options (like --no-fast-pskip or --no-dct-decimation), --aq-mode 2 is redundant since it's the default, also the VBV paramaters are completely wrong... that shows he is incompetent (so my comment even if may sound a bit harsh is not an offense, it's just the reality). He shown he doesnt know anything about x264 coz he set the options almost randomly and he is still offending ppl and destructively criticizing x264 and the devs work without even asking if he was doing something wrong...
he joined the forum on march 2007 so he had all the time to document himself but obviously he didnt. He made 3 posts of which 2, in this thread, contain insults and are plain provocations... IMHO if he keeps that behaviour he better find another place. OT: anyone knows the AVC-HD exact vbv-buffsize?
