File size of DTS soundtrack

[406lx]

What is the file size of a DTS soundtrack for the average movie ( about 2 hours long)?

Thanks

thats like asking the filesize of a 2 minute MP3. You must consider the bitrate in order to determine its size. DTS uses a higher bitrate than AC3 or MP3 so itll be a larger filesize. But until i know the specific bitrate i can't help ya.

From what I've read about DTS, I recall that it comes in two "flavors" for DVD: 754kbps and 1509kbps. I'm under the impression that most DVD's use 754kbps audio since DD only uses 448kbps for most discs I own, but that may not go for all discs. So, lets assume a 2 hour film:

assuming:

1024 bits per kilobit
8 bits per byte
1024 bytes per KB
1024KB per MB

kbits/s-->bits(raw)-->bytes-->KB*sec*x(length)-->MB=size

754000bps*1.024/8/1024*60*120/1.024=662.69MB
1509000bps*1.024/8/1024*60*120/1.024=1326.26MB

It's been a while since I've calculated kbits>MB--my equations may be a little off, but at least you have ballpark figures to go by. Hope this helps!

ok sorry about the confusion. what i am planning on doing is making backups of dvds to dvd and i want to use the DTS soundtrack. However from abit of research it looks like it can`t be extracted from a VOB. I was just wondering how much space a soundtrack would take up but i guess that depends on the bitrate used.

Thanks. Just what I wanted.

thanks for the info on DTS bitrates, now i know a little more about DTS, as it is so proprietary, few people seem to know anything about it. All i know is that Sony disses Dolby's AC3 because it uses lower bitrates. Most people i've talked with and posts and reviews i've read have praised AC3 as being a superior audio format, sounding awesome quality and capturing everything that the movie has. This is kinda funny since Dolby's goal is high quality at low bitrates (=lower filesize which we all want) in turn this achieves their goal, yet Sony continues to say DTS is superior. I prefer AC3, but DTS is good too, whatever floats your boat, is all i got to say.

At the end of the day a dts soundtrack is too big to use, an hours worth will fill a cd leaving no room for video plus as far as i know there is only one program that can multiplex dts audio and that is the very expensive pro tool dvd maestro.

Im not sure if its possible to re-encode at a lower bitrate ..its possible to re-encode a dolby digital soundtrack using soft encode, i sometimes do this if i want a bit more for video when i make minidvds

Just for the record: Sony has nothing to do with DTS, which was created by Digital Theater Systems. Sony has thier own proprietary format known as SDDS (Sony Dynamic Digital Sound) that ulitizes the ATRAC compression format found in MiniDisc, and is used in Sony-owned theaters. Out of the three formats, no one has won out yet. . at the high bitrates they are using, there is going to be little or no difference in sound quality between compression formats. DTS tracks are usually recorded at higher volume levels, which may account for the fact that some people feel DTS sounds better (higher bitrate aside). I've always heard people say that DTS sounds better than DD, but not the other way around. They both sound fine in my opinion.

then i was misinformed about DTS, my bad, i remember somthing about sony being involved, but i do know sony has SDDS so whatever. Basically for DVDRipping, AC3 (DD) is the way to go, and if your just playing a DVD on a standalone either DD or DTS is great, whichever you prefer.

Is it possible to increase the volume of the dolby digital soundtrack. all the software i`ve seen is for wav etc.

from what i understand .. "Technicly" DTS is 6.1 ... meaning that you get a rear center chan ( home decoders just mix this in with the rear to make a phantom center in the rear ) ... this tends to give a bit more dynamic range in the rear channels and makes them more pronounced ... DD rear channls dont normly jump out as much ........
Alot of this is mute as it really depends on the orginal sound mix when the movie was sent to print ... fight club being mostly speach and music wouldnt benefit from it where matrix has alot more "effects" and may sound better , but matrix was never encoded in dts , Terminator 2 does have a studio re-mixed DTS track (collectors ed. dvd).

Personaly .... if a movie has a DTS i try to keep it ... if it's too big then i check it out on my home system .. if i think it's worth it i'll cut the credits or somthing .. if not then dts gets striped, Snoop Dogs "BONES" .. with DTS - have to dump all the menus chapter selects .. without - you can keep the menu.

What software are you using to extract the DTS from the DVD.

Vobrator has been mentioned to me???
