Zigzag line encodes

[naro]

Same here, I hope this can be corrected...whats funny is I encoded another movie today and it did not seem to have this problem. But another movie I did right after did have this problem... No idea whats causing this issue...

Hi naro,

In post #9 of this thread (22-08-2005 13:26), you posted DVDREasy.log from a GOOD conversion (no interlacing problem) using HC encoder, right ?

Could you please post DVDReasy.log from a BAD conversion (with interlacing problem) using HC also ?

I must compare both logs to see if I can figure out what's going on . . .

Thanks !

Cheers,

DVDREasy

Successful backups:
Casino
Black Hawk Down
The Deer Hunter

Unsuccessful backups: (severe visual interlacing)
Hostage
The Aviator

I used DVDREasy + HC (all titles NTSC)

PS - I was able to make a good copy of The Aviator using HC with DVDRebuilder.

Thanks Shocker9000

What I need is DVDREasy log from one Successful backups and another from
Unsuccessful backup, so I can compare them.

Could you post them ?

Thanks !

Still having this issue, tried encoding with CCE Finding Nemo NTSC. I will post the logs shortly.

This movie also had another problem, where the movie had certain spots, notably in the begining where it cuts out and a special feature/bonus video displays, with movie audio still going. This seems like the duplicate VOB ID issue explained over at Doom9's site:

http://www.doom9.org/mpg/Eyes_Duplic...nding_Nemo.htm

[naro]

I would like someone else to confirm this besides me, but I think I may have found a solution.

I took the time and went through the DVDR backup process manually, each step independently from one another. Only difference being the AVS script file DVDREasy uses compared with what I used. After some reading and realizing this is a interlace/combing/IVTC problem, I used the Decomb.dll plugin from "Decomb Plugin for Avisynth". This plugin is mainly used for "...removing combing artifacts from telecined progressive streams, interlaced streams, and mixtures thereof." In the end, this does seem to resolve the interlace/combing/IVTC problem I have been receiving when encoding some NTSC films. I will try this on another few films to confirm, but would also like to ask anyone else to please try what I did and confirm.

Decomb.dll plugin: http://neuron2.net/decomb/decombnew.html

Basically just added the following lines to AVS file:

LoadPlugin("<drive letter>:\decomb.dll")
FieldDeinterlace()

Progressive content only! For interlaced content, simply have:

ConvertToYUY2(interlaced=true)

This is purely based upon what I have researched so if anyone else out there can correct me or fill me in, please feel free to. DVDREasy, let me know your findings on this...if you need an NTSC film to try, I wouldnt mind spending the time to send you a raw...

Also please check out the following URL: http://www.doom9.org/mpg/scenaid.htm
About quarter page down, doom9 depicts two pictures, "AviSynth tab" settings...for "Standard Scripts" and "NTSC processing"...maybe you should be implementing a similar adjustment scheme into your code depending on the movie?

All in all let me know what you think, im just trying to help as I love your utility, and just trying to help it become better...

[dvdreasy]

Hi Naro,

Thanks

I will investigate this ASAP !

DVDREasy, let me know your findings on this...if you need an NTSC film to try, I wouldnt mind spending the time to send you a raw...

As I told you, I live in PAL land and only have access to few NTSC movies.
All NTSC movies that I converted with DVDREasy were OK. If you could send me a CHUNCK of a NTSC movie (one with bad results with DVDREasy conversion) for testing, would be great

I will post my findings on this matter . . .

Again, thanks for your time and support !

Cheers,

DVDREasy

DVDREasy, I'll PM you once I have such a clip ready. I will have to borrow Heat NTSC from my friend as I remember that movie had horrible interlace problems. Another update. I made a mistake in my previous comments:

Should be for:

Progressive:

LoadPlugin(x:\dgdecode.dll)
ConvertYUY2()

Interlaced:

LoadPlugin(x:\dgdecode.dll)
LoadPlugin(x:\decomb.dll)
FieldDeinterlace()
AddAudio()
ConvertYUY2()

*The dgdecode.dll is from dgmpgdec, formally DVD2AVI - same thing.

Sources:

http://www.doom9.org/ivtc-tut.htm
http://www.doom9.org/***********?/decomb.htm

*EDIT* I give up the more I read on this the less I understand...I dont know what to set in the AVS to properly correct these interlace/progressive issues...this sucks...

[naro]

I just encoded Fifth Element NTSC, was flawless and looks fine, nothing wrong. But looking through the dvdeasy log, I noticed in the MPEGinfo STEP that it does not recognize the movie as being progressive (which it is) and also saying PULLDOWN needed: false. Isnt pulldown needed for NTSC progressive sources? The movie was encoded at 23fps and we need to brign it back to 29fps progressive stream?

Hi naro,

the frame rate is 29.97, so pulldown is not needed. You only need pulldown when the source is 23.976 !

the CCE settings seems to be right . . . Does the movie look fine ? did you notice any strange issue ?

[naro]

Looks fine, no strange issues... Overall I guess DVDREasy is doing everything correctly for NTSC progressive scan movies, no idea why some moves have this combing issue. I was able to get a much better reencode of Aliens, by changing a couple settings: Image Quality Priority to 5, 7 passes (cce 2.5). I heard that Image Quality Priority is different based upon the CCE version you use, so the value of 5 I got from the old robo method (for cce 2.5).

Special consideration, for movies containing multiple PGC's like Aliens and Finding Nemo, you have to pass the movie through a 3rd party utility first and extract just the movie. For example using IFOEdit or DVDShrink (no compression). Then run it through DVDREasy and you will get no jumping around issues of extras or a longer version of a scene, then back again. Hope that helps other people...
