Test that new AV component

[Marco33]

I'm alway upgrading or re-tuning or testing my home theater system. I don't feel that those "store bought" tester dvd's realy do the job. I always end up breaking out a movie disk to REALY test my system. When I show off my system to friend,just one single movie can do it justice...so I thought I would make one.

Taking bits and pieces of different movies and joining the clips together to make one great dvd to test and show off my sytem.

Sounds like fun so here goes.

What programs to use?
DVD decrypter and Cuttermeran should get us there + an autho program,Spruce has never let me down.

The movie criteria
16X9 only no 4X3 letterbox (converting will not help the image and great video is half the task.

5.1 souround from the original dvd.
If the original sound was mono but the dvd has a converted 5.1, I think that's ok but I can't see converting the original mono to 5.1 for this project.

The clips HAVE to show of the Video as well as Audio of your system so while the Intro scene to the Matrix is good the Lobby scene would be better.

With Decrypter in IFO mode we can pick out the chapter, stream process out the AV.

Now, the fun part.
Which movies?
Which scenes?

Right off the bat, I think I'll start off with the THX intro. The newer one with the rain. Lead that right into the Tie fighter attack from ANH. Matrix lobby scene is a given.

One scene from a movie shoud be plenty, 5 min tops.

After the THX intro, have the scene from Jurassic Park where you see the ripples in the glass of water as the footsteps get louder and louder. Once the T-Rex roars then go into your gratuitous shots

Do the depth charge scene in Episode I. Nothing else will show off your subwoofer range like that.

Maybe the White House explosion in Independence Day. Not the best of effects really but a famous effects shot.

Add the THX test signals as a first step

Pod Race scene from SW I -- a good motion codec test

Bullitt chase scene. -- barf bag test

Some good 5.1 music cuts -- like Orbison B&W Nite, Eagles

[Marco33]

List:
THX intro
Star Wars IV Chapter 39 (Tie Fighter Attack)
Raiders of the Lost Ark Chapter 3 (The Golden Idol)
Star Wars II Chapter 28 (Asteroid Chase)
Star Wars I Chapter 22 (Home Stretch)
Jurassic Park (on order)
T2 Chapter 57 (Terminator Serves Notice)

That should get me started.

@ Marco33

Sounds good to me :P

Question.. R U re-encoding, or just "taping" all these cut scenes together ???

NO re-encoding.

I want this to be fun, right now I'm having AV sync problems... not fun.

make sure that *ALL* the sources (all your cut VOBS) are the same fps
speed throughout.

Some MPEG cutters (whatever they may be) do not accurately cut them
evenly.

TIP:

First, try with using the same VOB source, but cut in different areas,
then try to merge them together, using the method you use earlier.
.
If they work, then try with *TWO* different cut VOBS, and use the
same method above. Find out where/which vob has the different fps
issue.

But, I suspect that using the method to *only* rip portions (chapters)
spanned across the disk, is what's probably causing your glitch.
.
You might have to grab the whole thing, and then do your cuts based
on the whole. (for each dvd disk movie) I know its a slow process, but
you did say its a one-time deal.., not something that you'll be doing
every day.

Just remember that most animations are usually 29.970 fps, and probably
Interlaced.. though some are Progressive.., and yet others are Film.
.
When you cut these, somewhere within this scene, the fps will change.
You have to cut in the first set of PPP II PPP II PPP II and grabing
chapters is not the right way, unless you are cuting inside the final
VOB area, withing the fps and Telecine range.
.
If you cut from the begining of the scene, be sure you start at the
first frame of the PPP (ie, note the <> marks the cut.. in
the frame below:

A) Chpt vob - 29.970 fps - PPP II PPP II PPP II
B) Chpt vob - 29.970 fps - P II PPP II PPP II PPP II PPP II PPP

then, the vob cuts:

A) -

PP II PPP II PPP I[I]
B) - P II

PP II PPP II PPP II PPP I[I] PPP

When we join, then become:

C) - PPP II PPP II PPP II : PPP II PPP II PPP II PPP II

The above, for C) is for only two movie scenes cut and then joined,
when the frame rate is the same for both, and the Telecine is consistant.

Yeah, I was trying a short cut but, alas I think this is the only way.

I'm going to start over.

[Marco33]

Decrypter in IFO mode, stream processing leavs me with an M2V and an AC3 file.

The sound seems fine but the video file plays shows the wrong time and the clip plays kinda fast.

Loading it into Cuttermeran shows the wrong time and Windows media player plays it too fast.

WinDVD plays ok but the time is screwed up.

I might have a codec problem.

I'm going to cut it and burn a tester.

I'd just drop full VOBs and add new chapter points. The point is to test the DVD player's decoder right? Not your encoding technique.

Drop full vob's ?

My home theature dvd player?

no encoding.

[vhelp]

Try another dvd ripper app.. like Smartripper. That is what I use.

If things don't work out, your best alternative is to re-encode
but use what I use.. CBR 9000 bitrate. After all, you are demoing
mostly action (for show-off purposes) and using too low a bitrate
will show lots of pixelations inside your demo demon. Don't
short-change yourself. If your last resort is re-encode, then do
consider my notes.

The idea is to leave the encoded data "as is" to accomplish your test of playback hardware. Part of the scentific method. Control your variables.

I wonder???

I've just recently moved my DVD writer from inter to external hooked to my USB. I'm gonna try ripping the whole disk to the HD then rip the AV out.

[Marco33]

Something is just not right. If I take the original ripped m2v and ac3 and play each in Windows Media player the sound time is right but the movie time is wrong.

If I load them into my autho program it plays fine. If I cut said files and load them into my autho program it plays out of sync.

Bothers me the original video file has the wrong time. This is the root of my problem since I've used different cutting programs and gotten the same effect.

[Marco33]

Dvdshrink... that's the stuff.

[Marco33]

Which scene from the LOTR trilogy should I use?

I have the trilogy, watched it once and liked it but... not real versed with it.

[ToddS]

Check out the list of demo scenes on the SVS site. I think it may give you a few more ideas.

Killer

[Marco33]

Success.

Using Shrink I ripped just the scenes I wanted.
I took just the VOB files out re-naming them to a new folder.
Using DVD lab, leaving the vob's muxed, I authored a dvd.
