MeGUI Custom x264/AVC video profiles. - Page 21

I could do that. It would be better, but to measure better compression this way should do it.

I think, I can use for the same source the same .stats file, because settings in 1.pass are identical, right?
It would speed up tests extremely.

I will get some tests on an Opteron 144@2250 too. So we will see, how speed differs from the settings. But he will use newest Sharktooth's profile.

Hey Sharktooth,

Just wondering where you found the specs for the HD-DVD profile. I have been able to find the blu ray specs but not the hd-dvd specs in my searching.

Thanks

Sharktooth · 18th May 2006, 13:13

Here and there this forum.
Im not even sure it is completely compliant, that's why i asked for testers.

@Deinorius: i thought you were using constant quant... crf is not good for that comparison.

berrinam · 18th May 2006, 13:25

You can use the same first pass stats file if the settings you use for first pass are the same. Since you are testing turbo, that's probably the case.

I'm not sure how constant quant fits into all of this, but I still imagine that 2pass is the best scenario to test the efficiency of settings, because it ensures that filesizes are the same, so a visual judgement is the be-all-end-all.

Sharktooth · 18th May 2006, 13:31

then you'll need PSNR or SSIM or whatever to distinguish one encode from the other...

The new profiles require MeGUI ver 0.2.3.2134.

Ben Waggoner (Microsoft) over at AVS Forum says 250 frames is too long for GOP length, but he can't tell me the exact limit because of NDA. FWIW, Apple's DVD Studio Pro docs show the GOP for HD DVD can be set from 0.5 second to 5 seconds, which would be 12 to 120 frames for film content. I am still trying to find out exact specs, so I will post back when I find them.

Mainconcept's HD DVD preset shows 2 B-frames, so maybe it is best to use 2 instead of 3 to be on the safe side.

Well, if you do it by CQ, then you are using a Quant metric instead. Who knows how good that is? But with 2pass, you can resort to trusting your eyes, whereas you can't with anything else (because the filesizes aren't the same, so visual comparisons are useless).

Question.....
Would HQ-Insane be good for an hd source?
Encoding time is not important to me.....

foxyshadis · 22nd May 2006, 06:06

All of the HQ profiles are good and slow, Insane extremely so. "HD" isn't nearly enough of a reference, so just try a few profiles and see what you think.

Sharktooth · 22nd May 2006, 14:19

v26: updated SA-HD-DVD profile.

smok3 · 22nd May 2006, 14:43

Sharktooth; it would be actually great if you could provide the profiles as x264 command lines as well as xml.

Sharktooth · 24th May 2006, 17:04

ill see what i can do

buzzqw · 24th May 2006, 18:05

@smok3

quick way: open megui, load a profile , check show command line.

I have HD DVD player buy in USA. When I put H264 video from x264, I have warning messages
about maximum bitrate (--vbv maxrate at 12000kps and --vbv bufsize use ) in HD DVD authoring
software (professional).
There is some pic over the maximum bitrate of HD DVD specification.

And when I play in HD DVD player (DVDR with HD DVD image), the video block when there is pics
of maximum bitrate.

The Sonic Scenarist tutorial say the GOP must be less than 0.606 second,
so 18 frame in NTSC framerate (29.97) and 15 frame in PAL framerate (25).
for AVC (H264 video) and VC1.
The number of B frame is 2 no more.
No information about MBAFF and PAFF use (I don't recommend it because
there is not lot of hardware chipset that support it).

I need to know how I can encode in CBR with MeGui (-ratetol at 0 don't work -> change at 0.1)
to test video in HD DVD player.

And we don't need to put maxbirate at 25Mbit/s because at 10Mbit/s and ABR at 8Mbit/s
the picture is beautiful (LCD Samsung 42" HD Ready).

I actually think this might be worth integrating into MeGUI, to extend the 'export profiles' function -- it could export them in a plain text or .bat format (couldn't be too hard).

CruNcher · 28th May 2006, 03:52

Golgot13 could you please try this encode with Scenarist 4

http://rapidshare.de/files/19907080/...part1.rar.html
http://rapidshare.de/files/19907412/...part2.rar.html

thx in advance

Golgot13 · 29th May 2006, 01:05

The big problem with x264 encoder is " NAL_HRD_PARAMETER ".
In this header, somes professionnal software read information about H264 video file.
The most import information is the bitrate (there is a minimum and a maximum
to be compliant with HD DVD and BluRay compliant).

The last version of Scenarist 4 don't accept file without this header.
I must to use a older version to mux the video data. And demux (with transport stream software)
the EVO file to have good file (with the most important header: NAL, VUI,...)

I recommend to encode in CBR mode but I don't know how I can do this with MeGui
(no option in MeGui to encode in CBR ???)

Scenarist 4 accept mp4 container but with only video stream H264 (compliant with
HD DVD and BluRay specification, with all headers....)
AAC audio track is not compliant HD DVD/BluRay.

On the iPod profile, the "I4x4" and "P4x4" macroblock options are not greyed out but they aren't enabled either. If I enable them, will the encode still be playable on an iPod?
