I do get the impression of lower overall quality watching full screen, but I could be wrong. I'll shut up about it until I actually do a test or two of the same DVD at different resolutions.

Special option for minimum quality indeed would help in case you really wanna have a high-quality encode with a given target size. I'll think about it, but no promices.
I was thinking of an option to change the target quality from 65 to whatever, not necessarily to set the minimum quality.

Well, target quality is minimum quality :)

Really? Sometimes I get qualities less than 65. My last movie for example ended up about 55.

well its lowered to 55 if resolution is about to drop below 608 for widescreen movies or 512 for 4:3 movies. Also prediction is still prediction - what you really get is percentage after the first pass.

mostly cosmetic stuff plus better handling of transport streams.

atom-

can i achieve it manually, somehow?

Yes, but someone else will have to tell you how to set up the .credits file, because I can't remember.

...but i'd have to choose a fixed quality for the encode of the credits...

That's right. And the quality is by percentage, and not quant. So if you choose 100%, then the whole movie is done at full quality.

- if TS has a proper PMT/PAT tables then audio streams of the first program displayed in the GUI

Sorry, as non-english spoken fellow, I don't understand the words
in change list (on Page 1, Version history 1.43b)

TS = Transport Stream?

Never mind, will do try and error method, to overcome the miracles :o :D

..but either way i couldn't control the size of it. well, it's not _that_ important after all.

btw i succeeded in doing a 2 dvd movie in one run as one file without sync. problems. another movie like that desynced badly. the synced one had -80ms audio on both dvds. the unsynced one differed by 20ms and ended up being badly out of sync.

essential reading is here (C11): http://www.vslcatena.nl/~ronald/docs/xvidfaq.html

AutoGK uses Zones mechanism to encode credits. By specifying starting frame 0 you're forcing it to use Zone for the whole movie (and therefore greyscale encoding will be applied to it). Weight in the Zones is what AutoGK is calling quality.

Weight in the Zones is what AutoGK is calling quality. ok, got that right now. thx for the info. any chance you might implement it sometimes as a switch or a .bw file to take care of the hole movie for convenience?

Yay! This makes inputing seasons of TV eps so, so much easier. Thanks a bunch len0x.

Having said that, I have a bug report and another possible request :)

First the bug report: I'm unable to use "Preview" twice without reloading the Input clip. I found this when I previewed once, then tried to adjust the width and preview again. It gives me this error (I'm posting the entire log just so you can see that it worked once, and then failed):

The error doesn't depend on changing the width, that's just how I stumbled upon it. This happens with both DVD and File inputs.

Second, I have yet another request (sorry). Would it be possible to include a .deint as an opposite route to .ivtc? I have a couple documentaries that are hybrid, and applying any kind of threshold value just makes the FILM and NTSC material equally poor-looking.

[Master Ninja]

Just testing out the program now, looks nice! One quick question, though:

I'm trying to rip a DVD of TV episodes, where each episode was one chapter of an entire PGC section. I ripped each one to a separate VOB file, but if I try to select the directory as DVD input, I can't specify separate output files. If I try to select the files individually, it keeps displaying "Unknown Audio Track". Is there any way around this?

What do you mean by "can't"? You should rip then into separate directories, not files. Keep in mind that subs will be unavailable for second and later epsodes.

You're saying that deinterlacing makes FILM parts looks ok? I don't believe that. What's FILM percentage of the source?

P.S. what does your avatar say ? :)

Thanks. I know how to fix that.

Maybe it's because I'm used to FILM material being broadcast at 29.97, but it looks fine to me. Obviously it doesn't look nearly as good as if it were IVTCed, but when the framerate is 29.97 there's only so much you can do to salvage the FILM material. Simply deinterlacing it preserves some of the smoothness and doesn't arbitrarily attempt to blend frames the way using threshold does. I think.

But having said that, my point in asking for the .deint had less to do with the FILM parts and more with the NTSC parts. At 29.97 the FILM matierial will look poor at basically any threshold, but the NTSC material is native to 29.97 and looks perfect when simply deinterlaced. But once a threshold of any kind is applied, the interlaced material becomes jerky and unsightly. I'm not a fan of the threshold values for hybrid clips because I think there's minimal quality gain for FILM material and a very obvious detriment to the NTSC parts.

Here's the analysis part of the log for your reference (this is from the most recent one I did):

[6/29/2004 6:39:29 AM] Source has percentage of interlacing in motion areas: 58.73
[6/29/2004 6:39:29 AM] Source has percentage of telecined patterns: 45.47
[6/29/2004 6:39:29 AM] Source has percentage of progressive patterns: 9.66
[6/29/2004 6:39:29 AM] Source has percentage of interlaced patterns: 44.87
[6/29/2004 6:39:29 AM] Source is considered to be hybrid (mostly NTSC).

P.S. I'm a tv nut, so my avatar is the screen caps of the 'written by' credits of my three favorite television geniuses: Joss Whedon, Aaron Sorkin & Amy Sherman-Palladino. :)

I've messed around with it since my last post and it apparently only happens with pure FILM material.

The header of a D2V file in which the error occured:

DGIndexProjectFile06
1
15 D:\DVD\test.vob

Stream_Type=1
iDCT_Algorithm=5 (1:MMX 2:SSEMMX 3:FPU 4:REF 5:SSE2MMX)
YUVRGB_Scale=1 (0:TVScale 1:PCScale)
Luminance_Filter=0,0 (Gamma, Offset)
Clipping=0,0,0,0 (ClipLeft, ClipRight, ClipTop, ClipBottom)
Aspect_Ratio=16:9
Picture_Size=720x480
Field_Operation=1 (0:None 1:ForcedFILM 2:RawFrames)
Frame_Rate=23976
Location=0,0,0,27A1

If I change the Frame_Rate field to 29970 and re-save it, then it will play again (without re-indexing) -- but only once, then I have to make the change again if I want to preview it again.

EDIT:

Oh, btw....

Aha, 24fps is not recognized as NTSC framerate for mpeg2 obviously. During first launch of preview this value gets substituted for FILM materials and fails afterwards. I have to revise it for preview purposes...

You sample was actually very useful to me as it contains several audio streams (which AutoGK can handle now). Do you have a sample with several programs in TS ?

[fakey]

Thanks for the great work len0x.
I've got two questions.

a. Is it possible for the AutoGK not to reset the codec settings and use the one that is already present in windows registry?
In that way more advanced codec settings could be possible while not hurting the 'easy job for newbies' scheme.:)

b. Is there any plan for the international support(language conversions) like what is done in GK?
It will do a great help for the newbies to see the program in their native language.

Let me say you're simply amazing. Thanks so much for adding the .kerneldeint hidden option so quickly!! I love it. I'm going to try it out on my next batch of encodes.

Hi guys,

i got a weird problem. Ever since AutoGK changed from using DVD2AVI to DGMPGDec audio is out of sync. When i use version 1.25 i don't have this problem. any solution guys?

[((( atom )))]

@len0x,

about the min quality idea again:
i just encoded a couple of old movies again and on some i get very visible blocks and edge-ringing.
so i think i can dare to state that the min quality wich is necessary for a rip to be visibly good strongly depends on the source. for old/bad/noisy movies i think it naturally is a bit higher.

do you plan to gift us with a little option to adjust that factor? i'd be happy :)

[len0x]

Originally posted by ((( atom )))

actually no, quite the opposite. You will probably see the same effects in the original source, so for noisy b&w sources I personally (and not only me) accept quality of as low as 50%... It is a waste of space to try and achieve as close result to the original source as possible.

It is a waste of space to try and achieve as close result to the original source as possible. hmm, that is sad now. so i'll possibly have to switch to gk for all my old movies again. :(

the source btw copes quite well with the noise and all, the encoding really looks worse then the original.
the discussion about really hq rips was started before and i actually understood you'd see some use for that fuction, too. that was why i asked again.

[Carraway]

Question: was having an "average Kbps" option (in 2-pass mode, 1-pass is useless) ever discussed as an additional alternative to target quality? I was ripping basically all the extras off a DVD the other day and I quickly realized that they all varied wildly in compressibility so "target quality" wasn't really an option (not to mention that autosize isn't triggered in % mode), and previewing each individual file to ascertain its length in order to choose an appropriate filesize was sort of time consuming. I wasn't going for exact filesizes so it seemed like an ideal situation for encoding the clips with an average kbps. Has this ever been floated/vetoed as a feature? (Btw, this is probably the least I've ever been invested in a feature request, I'm just asking as a just-out-of-curiosity type thing).

Please do the following:

- demux audio manually using DVD2AVIdg and DGIndex
- if delays in the filenames are equal then post both log files when converting with 1.25 and latest version.
- if delays are not the same then nothing we can do here.

P.S. try also differet kind of audio (AC3/VBRMP3/CBRMP3)

may be it was, but having a user which "doesn't care about file size and doesn't care about quality" is too much for such automated tool. Extras are indeed bummer to encode but having an option to encode with bitrate greatly reduces chances of getting a decent quality rip (and ppl WILL use it for main movie rips). So its better not to have it at all...

That's understandable.

added hints into job list to show settings for each job

This is great. I sometimes sorta freak out after I've just added like 25 VOB's to the queue that I might have accidentally added them with the wrong settings, then I'll delete them and re-queue them just to be sure. This feature will save me a little bit of my sanity. :)

when i manually use DVD2AVIdg it creates delay in the filename but DGIndex doesn't seem to create delay in filename. This is casuing the audio out of sync problem. When i encode with mp3 i don't have this problem. hope someone can help me.

Hi, i've started to use AutoGK and I really like the results it produces so far. Sharp images without a hussle, like the program promises! I am interested in knowing on what base the program decides on cropping? I haven't been searching for long in the forums yet so I might have overlooked a similar question/answer.

all with all, congrats on a job well done, great peace of software
