We won't get a better result with 2 pass ?

[Japhsoncross]

IIRC, trellis 1/2 and deadzone settings don't work together.

ooopsss ... with fgo it's trelli 0 for better grain retention.

No because crf mode produce exactly the same encoding than multipass mode (at the same bitrate). If you want target bitrate there are multipass profil in the pack.

[Atak_Snajpera]

You will get better quality if you remove those stupid lines
--keyint 24 --min-keyint 2

Tested works on PS3 and others (standalone players)

certainely not ... lol.

1) --keyint 24
Max IDR must be 24 frames if you want compliant BD profil. All the BD authoring soft want compliant GOP. Moreover 24 frame is a relative long GOP: very long GOP at 240 frames will produce less than 5% quality improvement. It's 1 sec for the max gop and anything else for Blu Ray.

2) --min-keyint 2
Usefull if you want make BluRay -> HDDVD flag convertion with H264info for example. Moreover by default minkeyint at 10 can be problemtic with scenecut detection with GOP at 24. Consecutive IFrame can be problematic with authoring software (frame drop with cinevision for example)


PS3 profil (with mp4) is not a compliant BluRay profil. --keyint 24 --min-keyint 2 produce the best possible compliant stream.

we had to add theses options for Adobe Encore and Scenarist, but since tsmuxer is released, we don't need them to authorize our bluray for the PS3.. but still wihtout theses setting we won't be able to import the video in theses softwares.

I don't use them anymore, because I only want to watch my video on the PS3, but if I want to add menus.. that will be another story.

it's what I think

cool, but because I always want something that fit on a dvd, I use the 2pass.

I had trouble with crf 20 on anime with ripbot in the past, so I stop using crf to replace by 2pass.

update profil

[-TiLT-]

Rar is down again :(

And I thought Blu Ray is --b-pyramid incompatible.

[Sharktooth]

nope, just some players or old softwares. i excluded b-pyramid from the megui presets for that reason (not that it is a big advantage in quality by using it though). also i found a typo --min-keint 1 instead of 2 in the blu-ray and avc-hd presets (while HD-DVD was correctly set at 2), so i will update them asap.

Is this typo going to cause any payback problems with files already encoded using this profile?

[Sharktooth]

not at all.

[Chefkoch_ico]

Just saw it too. Plz upload again, if you have time.

Thx in advance

You know I have seen several time you saying you'll update profiles, but so far every time megui updates I get audio profiles updated (what can possibly warrant updating them several time in the past few weeks?). So is it the case that you just didn't update x264 profiles yet, or is my megui not getting the right profiles updated?

[nurbs]

If you want do try the new megui profiles (http://forum.doom9.org/showthread.php?t=139765) no one is stopping you. They are available, you just won't get them via auto-update until they are finished.

[lexor]

Oh, I wasn't hurrying people along, I just noticed a patter of Shark saying he'll update x264 profiles, and then MeGUI updating audio profile and not x264. I thought that maybe megui wasn't grabbing the right one, i.e. something wrong with autoupdate. And since this is the latest of Sharks posts on the subject I thought I'd ask. I have my own edit of Shark's PSP profile that works fine for this.

[Sharktooth]

yep, the presets are not yet published in the megui auto-update but they're available at the link nurbs posted.
that way they can be tested and tweaked before being added to megui automatic updates.

So b-pyramids are supported by AVCHD/Blu-ray?? I also thought that it wasn't supported, cant remember why though ...

I'll try encoding an AVCHD with b-pyramids tomorrow and see if my panasonic will play AVCHD's with b-pyramids.

[Sharktooth]

yes, but not by some old players and old software decoders.

With 3 bpyramid you must use 3,2 for p,b ref: --ref 3 with x264.
