what?without shrinking it?
what is the approx time in minutes that can fit on a dvd without compressing it? i thought it was 120 mins
strangely enough i have never burnt a dvd that has not had to be shrank.

I would say never go by how may minutes. You have to go by how big the file is.
Example: Mulan 2 is only 79 minutes long ... but it's 5.89 GBs. It will not fit on a single layer dvd.

Usually the extras.
Mulan 2:
menu: 58 MB
main movie: 3,667 MB
extras: 1,053 MB
unreferenced material: 1 MB

yes but,if a movie clip is say "4gb" in size which equates to say "100mins"
then another movie clip of also of "4gb",are you saying there is a possibilty that the running time may be different.say for example "120 mins"
i know extras etc make the size bigger,but a "byte" must equal something in terms of milisecs?
1 gb must equate to specific amount of minutes?
i mean when refering to cd-r,700mb is 80 mins approx.
with kind regards hursty

Lord of the Rings,return of the king,over 3hours and 10 mins on Main Movie only, single DVD-5,DVD Shrink,with enhancements,and Nero to burn.My backup target was set to 4300 Mbs.That was some major shrinkage,1 pass only. No re-running through DVD Shrink a second time.
I have gotten quite a few "b" movie dvd's,entire dvd well under 4.3 gigs without sacraficing any extra crap and no compression at all.

Actually you're just,lucky on this one. To answer your other questions -

No a byte doesn't euqal a milisec or a microsec kind of like saying why doesn't a volume equal a weight it just doesn't. A bit more time in school will explain why.
As long as the file you wish to burn doesn't exceed (go over) 4.36GB (the true size of a DVD NOT 4.7GB) you can use DVDD to rip and to burn and all will be the same as the original, a 1:1 copy.
When your file exceeds 4.36GB then DVDD won't work. Refer to the guides in my sig.
Cheers,

then why when you purchase dvd blanks they state they are 4.7 gb/120 mins?

Even a humble grasshopper like me can answer that one.
It all depends on the quality setting or compression of the rercorded material (ie how much information it contains).
Put another way:
According to the back of my DVD +RW packaging 4.7 gigibytes (actually 4.36 but who's quibbling)is the equivalent of ALL of the following:
4.7 gigs= 60 min XP (excellent play)
4.7 gigs= 120 mins SP (standard play)
4.7 gigs= 180 mins LP (long play)
4.7 gigs= 240 mins EP (extended play)
4.7 gigs= 360 mins SLp (super long play)
So evrything depends on the quality of the recorded source and how much you compress it (dvd shrink etc) before burning.

Or a more technical way to explain it is:
In marketing terms, the DVD capacity is 4.7 GB. But, the actual available size is 4.37 GB. This is because "giga" in the real world has two calculation methods. One is 10 to the 9th power, which is 1,000,000,000. And the other is 2 to the 30th power, which is 1,073,741,824. Thus, 4.37 * 1,073,741,824 is nearly equal to 4.7 * 1,000,000,000.

i think you have mis-understood what i was asking.
what i was refering to was that if you had 2 different dvd movies,each with equal playback time,for example 90 mins...on standard play...will the data size be the same?
so in plain english
#1 movie=90 mins
#2 movie=90 mins
will they be the same file size?
with kind regards hursty

If your doing the full dvd ... I would say no. If your doing just the main movie, dunno .. never do just the main movie :)

has anybody got to grasp the qustion that i asked!!!
will 2 different movies of equal file size play back in the equal amount of time?
or does the content of the movie affect the file size?
in otherwords will a 5 min clip with lots of detail, ,contain more bytes than a 5 min clip of simple detail,? with both clips having no compression etc.
i am guessing that the more detailed clip contains more bytes....even though they both have the same play back time.

hursty,
Why don't you find two movies that are the same length. Rip w/ Shrink ... just the main movie w/o compression.
Let us know :)

@flip
i have tried what you suggested and have come to the conclusion that it all depends on the content of each "frame",not neccesarly the quality(assuming there has been no compression),on original movies,it appears that no special attention has been paid to the actual "main movie",in terms of less compression,at the manufacturing stage.
i have tried several original dvd,each time,the more content,in term of "detail on each frame",the higher the "bytes",even though the playback time is the same.
i can say however that each mb did average about 1.5 secs in playback.
so on conclusion the more detail on each frame,the more the "bytes"
a 5 min clip with lots of detail,say with explosions,flashes etc etc.(you get the idea),will be a bigger size file,than say,a 5 min clip of say,a black screen.
you probably already knew this
thanks for all your input,it was a totally useless piece of information i wanted,but there you go!!!!
with kind regards hursty

Your testing makes sense- size does not equate(sp)to time.
Isn't this stuff fun?!

thats what i was trying to work out...
when sold dvd,they usually come as "4.7gb,120 mins"
(standard play),but it all seems to depend on what the actual movie is,in terms of detail,for how many minutes they can hold,without compressing them.
my thoery is its not in the quality,its in the detail per frame.when dvd's are made,i am led to believe that each frame,when made looks to repeat itself,looking for the same information on the same frame,if there is a lot of different details that dont match each other on the same frame,it results in more bytes,and like i said previoulsy a black screen would just repeat itself.thus less info.
so i cant really get my head around the whole "dvd 4.7gb 120 min" thing,because that could be anything in terms of file size
with regards,and still a slightly confused
hursty

Yeah,it does get confusing esp. for a mathmatical slug like me! I guess that's why the alogorithims per encoder are so important and even the best ones are using guesstimates when it comes down to it. How acurate can that be?!
Taking your theory about black pictures a bit further is it logical to think that recording a totally black dvd one could get over 5 gigs on it? Or should we use white since white is the absense of color and therefore require much less bytes?
