Dvd Rebuilder technical

Not really looking for easy answers, more opinions than anything. When a disc has both 5.1 and 2ch for the main title, I usually remove the 2ch. 3/5 dvds anymore dont even have 2ch. I gather 5.1 is more a standard, or hardware can easily convert 5.1 to 2ch. Is there some reason I shouldn't remove the 2ch? That would suck. Because 5.1 luckily is 100% of the time default, and removing the 2ch gives a 5-10% quality gain on main title. Hmm... I think I may have answered my own question here. Suggestions???

 

I personally see no advantage to keeping the 2 ch audio. For those who don't have a home theater setup, when they finally do get one, they'll wish they kept the 5.1 audio.

 

Well...rebuilder just irritated me! I told it not to touch the extras and it stole close to 400MB anyway!!! I compressed the extras with shrink that way I knew exactly what they would look like in 1/3rd the time. Besides, I think the 10% setting would not have been enough, and 25% is usually too much taken from the extras. Ok yes yes, im critical LOL Any thoughts on this??? I suppose I can rerun it through rebuilder and just try the 10% setting. But im still confused as to why rebuilder would steal from the extras, when NOT asked to do so!

 

Exactly how did you set this?

 

Yah...quite the morning here for me LOL. Shrink did a pretty good job with the overall movie too(Zack and Miri make a porno). Totally not settling for shrink though!
Ok...What I did was, compress the living...turds out of the extras, 45% of original(NOT BAD), compress the menus as well(Rebuilder wont go as far as I like). Shrink took the menus down to 10% of original!!!! VERY impressed. I couldnt believe that 10% appeared unchanged! But then, the menus had very little animation, motion, Etc. I DID NOT compress the main title with shrink. Then ran it all through rebuilder, NO compression to extras, do not encode menus, and yet...it stole close to 400mb from the extras I already perfected! I do still have some digging to do with the program. Pretty busy guy. Just havnt seen the need when the default is pretty good But now...
EDIT - sorry, I used CCE if that makes a difference. Oh heck, heres the log. If you wish me to remove it, I WILL!

Heres another little tidbit, buddy

Creaky, im sure looking at what im working with, you'll understand why im doing it this way
Thats correct. Shrink than rebuild. I wanted to MASTER the extras this way.

 

Your kidding! I realize extras are not always worth keeping, but in this ones case, THEY ARE A RIOT! LOL

So...you think that shrink could be corrupting(For lack of a better term) the files in such a way, that rebuilder is confused? I have noticed in the past, that its stolen space from the extras without asking. but since it was a marginal loss(50-100mb) I didnt complain about it. But...400MB is pretty extreme. Especially when its Quite noticeable!

 

LOL, on a good day, I might say something like that. Thats good info man. I guess I dont doubt that, given what im seeing. Im rerunning a different backup to see what happens. Its possible that rebuilder is seeing the source files exactly as it should (ONE Main TITLE!!!)

 

Ok, it seemed to acknowledge the deleted scenes as such it robbed them more so than the main title. I am however still not complete. It just doesnt encode/rob the menus as much as I would like. It could have taken MUCH more from the menus(300MB). So now, im gonna compress JUST the menus, and rerun it through rebuild and see what I end up with. will post tonight about success. Probably gonna change the output size as well. It could be using another 40-50 MB.

I REALLY want a quad creaky <----sinister looking grin

 

If you are concerned over the menus, then use MenuShrink, prior to running thru Rebuilder.

 

If you don't want compression on extras or any segment, you need to use the segment viewer to set these to no compression.

 

OK...MUCH better! So...taking 300+MB from the menus helped ALOT. It split that extra size between both titles. VERY awesome! I can be happy now. I imagine however, that this segment viewer tactic you speak of, could be invaluable! I imagine I will use it eventually Thanks Dialysis, for your input.

Dude, YOUR AWESOME! I looked for something like that a while back. Thank you However, both shrink and rebuilder have accomplished this job. Output is still slightly small...but, its within 30MB of where I want it. And given the imperfections im seeing on my TY's, it might be better to utilize LESS of the outer area of the discs!

 

If you an animated menu, neither DVD Shrink nor rebuilder can go as far as MenuShrink. They compress it but MenuShrink will reduce it to a still image with or without audio. Just for instance, on the movie Wanted, the original menu size was 52.16 mb after running MenuShrink it is 2.43. In the big scheme of things not a lot of MB, but every little bit helps.

PS- Found a better example: Madagascar: Escape 2 Africa- Original menu size was 300.77mb, shrunk size was 5.60mb. Saved 295.17mb.

 

I appreciate that buddy I guarantee i'll be using that badboy now! I could certainly care less about the way the menus look.

 

Yup. Just saved myself 150MB. Shrink could take it to 89MB where menushrink took it to 30. But that was keeping the audio. I thought I would try that first. I imagine it'll save me even MORE space in the future. Ive seen menus in excess of 600MB. Forget what it was. You have yourself a good weekend Ferguj1

 

Glad you like it. I don't use it a lot but when I need the extra space it is nice to have. You have a good weekend as well

 

DVD Shrink even under no compression sends its files through the transcoder and there is no way to separate the two. That doesn't mean that a reencode with DVD RB will fail, it's just not necessary since RB can also edit files.

A transcoder leaves the original content as it is and compresses it to fit to a smaller disc. An encoder redistributes a movie across its entire length making bitrate calculations that allows for bitrate reduction where it's needed less, and then uses it where it's needed most. I still have a copy of DVD Shrink and I still use it for legal backups of work discs used in meetings, but I never use it for my own backups.

 

Yah...I generally only use dvd shrink if I can keep the main title within 90% of original without robbing the extras too much. Depending of course. Sometimes the extras just are not worth keeping! I wish ALL movies would include a Gag reel. You gotta know ALL actors are not perfect, LOL. Its humorous watching especially the big actors/actresses screw up, LOL

Call me crazy, but I just dont think Shrink does that bad a job. I have a 50" plasma that doesnt lie! It really depends on the situation though. A 3hr movie will DEFINITELY benefit from rebuilder!

Even then however, it depends on the source video quality as well. I swear the industry has begun slacking, LOL
