Blade 2 region1 DTS track problem?

[armyb77]

I've been trying to copy Blade 2, but i'm having a problem with the DTS track not muxing properly. Maestro excepts the .DTS files that I have ripped using DVD2AVI, and SmartRipper, but I can't offset the track to mux properly. I also tried to use Scenarist, but Scenartis won't event except the file(error DTS track should not have extention frame)?? Anyways does anyone have an Idea of what I can do to resolve this?

All Ac3 files have a duration of (01:56:43:00)
but the DTS file is set at (01:56:42:11)??
is there a way using Maestro to reset the timecode manually?

I've read all the posts on DTS, but none of them have the answer.
I would like any input someone could provide

Thanks

Try zooming in (using the '+' button) until your Wall Clock is shown in frames. You'll see "0 Fm" on the left followed by "10 Fm" etc. Add your DTS track now and make sure it locks itself along the left wall.

Before I knew about this and I had the same problem as you, I use to add the 5.1 ac3 first, then the DTS. Create the title set and then use ifoedit to strip the ac3. This always properly aligned the DTS audio as well.

[armyb77]

Good Idea, but unfortunatly not the problem. The problem is the DTS track has a delay of 667ms and the ac3 tracks have no delay. When I copy the DTS track it's not doing the time delay correctly.

I'm not too familiar with Maestro, but Blade II has a (very impressive) DTS-ES track. This is actally a SEVEN channel track instead of six. Maybe Maestro can't handle 7 channel tracks? Just a thought.:confused:

DTS-ES has a discrete centre rear, ie Dolby Pro Logic style stuff, but only in the surround channels, its not a full channel.

as for the time delay, 667ms is ~20 frames (in 29.97 timeline), try offsetting the DTS track by that much and see what happens.

I had tried that and it still wasn't working, but I wasn't locking the track asset. Once I hit Lock Trackasset on Maestro, it worked fine.

Thanks for the help from everyone.

I am having some difficulties with this title and would appreciate any help from those who have done this one already. I have been able to successfully backup many titles using Maestro & CCE. (My thanks to all the people who've prepared the great guides!) However, I am not able to achieve good results with Blade 2. I suspect that it is related to the settings I am using on CCE. According to DVD2AVI, the movie is described as PROGRESSIVE FILM. However, according to BitrateViewer, the movie is Interlaced, DCT Type Field, Field Structure Frame, and Field Top First.

I have tried encoding with and without Progressive checked in CCE (both using ForceFilm and No Field Operations in DVD2AVI). In all cases, results were unsatisfactory. I have tried using pulldown with and without the prog_frames parameter. Still getting the same result.

The final output seems to have scan lines as well as jerky movements during certain sequences.

Any guidence in the settings I need to use would be greatly appreciated (for DVD2AVI, CCE and/or Pulldown). Thanks.

I did Blade 2 w/o the DTS track. Only problem I had was that the audio track from DVD2AVI was not able to import to Maestro, but that was easily fixed when I used Smartripper to demux the track.

I think the movie is Progressive, the introduction to the movie might be Interlace, if that is the case Bitrateview will label the movie as interlace instead of Progressive. What I do is load the second movie VOB and you should see it as Progressive in Bitrateviewer. So treat the movie as Progressive. I used force film mode in DVD2AVI. I think your problem may have something to do with the average bitrate on the movie. I can't remember but I think I used 3500 or 4000 for the average and cleaned up most of the gray areas for the second pass.

For pulldown, i used the gui version for pulldown (make sure you have .99d) and create the first file with prog_frames p, and the second one (drop) with prog_frames p prog_seq i and drop_frame_flag true

i have got the same problem as u 667ms off. Did u sort this problem out?

Try zooming in (using the '+' button) until your Wall Clock is shown in frames. You'll see "0 Fm" on the left followed by "10 Fm" etc. Add your DTS track now, click and hold the DTS track and slide it to the right until the endtime matches up with the AC3 tracks, and your start time for the DTS track 00:00:00;20. after that is done make sure you lock the DTS track asset.

As far as for the other person with the jerky picture, if you are in Norht America then you are dealing with 3:2 NTSC, which has IVTC, so the encoding process is a little more complicated. Make sure when you use dvd2avi that you don't force film, and you use the decomb filter with your AVS file. Also there is no need to use Pulldown if you do it the way I do. The settings I used during the CCE encode were:
AVS file:
LoadPlugin("D:\dvdstuff\decomb.dll")
loadplugin("D:\dvdstuff\mpeg2dec.dll")
MPEG2Source("E:\blade2\blade2.d2v")
Telecide()
ResampleAudio(44100)

CCE video settings:
Click the Following:
Add sequence end code
Upper Field First
Linear Quantizer scale
and DVD Compliant
Quality settings: 5

VBR Multipass
of Avg BR 2500,Min 0, and MAX 8000
I set the Max bitrate to 8000 because of the 6 audio tracks.

Everything plays great and looks good.

Good Luck to All

Armyb77,
The DTS track works fine in DVD Maestro by your suggestion of aligning it. Thanks.....The offset comes in between 0.6 and 0.7 secs in the time clock. I am assuming that this offset is equal to the delay of 667 ms indicated by SmartRipper when it demuxed the DTS track to separate file.

Anyone,
So why doesn't above work in Scenarist; in setting the time difference for DTS track??? Any Secenarist experts, please give this a try. There is no sound in preview on DTS track (sound in DD5.1 is fine), so getting it to sync up is painful.

Armyb77
As far as jerky picture in North America, you dont need to IVTC.
LoadPlugin("c:\avisynth\mpeg2dec.dll")
mpeg2source("e:\blade2\blade2.d2v")
resampleaudio(44100)
works fine. I did mine, which is NTSC. The jerkiness is also caused by not setting Top field first correctly (I think).

Here are my Blade 2 specs:

DD track is 01:56:43:00 (AC3 file says Delay 0 ms)
DTS track is 01:56:42:11 (DTS file says Delay 200 ms)
Video track 01:56:42:28

I watch the movie and it does seem a little out of sync.

How should I adjust in Maestro so that both tracks are in sync?

Thanks.

[shindsh]

Hoops10,
SmartRipper (demux to separate file) and army77 instructions. SmartRipper should give you 667ms delay track file for DTS, and 0ms delay track file for DD5.1.

As far as jerky picture in North America, you dont need to IVTC.

From what I have seen in over 200 movies that I've done now IVTC is a big problem. If not aplied on the movies that are then thier will usually be a combing effect, or jerkyness in the picture. Some movies don't require this I agree, but it works great regardless if it's needed or not, it just takes a little longer to encode, so I stick with the decomb.

[hoops10]

Just curious, I thought that as far as having sync problems with DTS and DD streams, that the authoring programs were supposed to handle the offsets automatically. Is this not true? Or because we are adding both DD and DTS streams, that we must manually offset them in Maestro?

[armyb77]

DTS is a "RAW" audio format that must be manually set if the offset is at the start of the film. This is the first movie that I had run across a problem with the DTS track, Maestro will place a DTS track where ever you put it though.

armyb77,
I thought you need IVTC only for movies that dont show FILM for 95% of the movie in DVD2AVI. This is usually the case with Interlace or NTSC movies (DVD2AVI guide).

For example Collateral Damage did not require IVTC.

Cheers.

[alex50]

My thanks to armyb77 and auenf. I was able to produce a very good backup using your suggestions. Much appreciated.

armyb77, I have a question as to when I need to use the decomb filter. This is the first DVD I encountered where it was necessary. How do I determine whether or not to use it? Usually, when I use Avisynth and CCE, I am able to encode at better than 1.8x. The decomb filter slows this down considerably. Any guidence on how to determine when this is necessary would be appreciated. Thanks.

hoops10, I do not think Maestro automatically syncs up the audio. The guides seem to indicate that it does, but that hasn't been my experience. I always use AC3 delay corrector to fix the audio file. In the case of the DTS tracks, you will have to manually offset it.

[armyb77]

alex50, I really don't know the answer to your question. What I will usually do is do a quick test on the movie(IE start encode until it reaches 1%) and then use pulldown, and review the test movie. If it looks good I continue with the encode, if I see shacky, or a combing effect then I apply the decomb filter.

If anyone has a better Idea then I would like to hear it!
Alex50 This might be a subject that would be great to start a new thread with?

Thanks

Hehe. Glad you got it working.

I found that it was only after I had used pulldown that the problems occured so I just used the original CCE file and will live without the correctly aligned subs.

[alex50]

After encoding a movie using the two additional lines in the AVS script (decomb.dll and Telecide), I am no longer able to import the chapter list into Maestro. Here are the steps I am taking:
1. Rip chapters list (Both CCE and Maestro format)
2. DVD2AVI into CCE
3. Import chapters into .ECL file (for CCE)
4. Take the new .mpv file and rename it .m2v
5. Import .m2v and .ac3 into maestro.
6. Try to import chapter list. This fails with an I-frames error.
7. I am still able to maunually enter chapters although in the end, it is off by a few frames.

Why am I not able to import the chapter list into Maestro when using the decomb/telecide combination? Do I still need to perform pulldown? I thought that was not required when using this method?

If anyone can offer a suggestion that would allow me to import the chapters when using this method, I'd appreciate it. Thanks.

[armyb77]

Did you make your FPS for CCE 23.976 or 29.97? You should need to set it at 29.97 because your not using pulldown with this method. I personally never use CCE chapters, but Try re-ripping your chapters with ChapterXtractor, make sure you set at 29.97fps, and set for Maestro. Under in the Header field you should see %hh:%mm:%ss:%cc. Change it to %hh:%mm:%ss. That should take care of the I-frame problem. Just import the new chapter list you created (.CHP file)into Maestro and your done. You need to remember that when you use Telecide you are almost restructuring the entire film so "I" frames maybe moved around. You will get good picture quality, but being accurate to the last frame when inporting chapters isn't always possible, you may only be able to be accurate to the nearest Second.

Hope this helps

I just wanted to say thanks. Using the %hh:%mm:%ss format worked. The chapters were off by a few frames but it still was better than entering it by hand. Thanks again.
