How much can you really fit in a 700 MB CD-R?

I have 703 MB of data. Will it fit on a 700 MB CD-R? Or does 700 mean EXACTLY 700? Does the hardware or the media make a big difference?


If you must know, the specs are:
Hardware: Plextor 16/10/40 with BURN-PROOF
Media: (1) Imation 16x 700MB/80MIN CD-R or (2) Imation 24x 700MB/80MIN CD-R or (3) PNY 16x 700MB/80MIN CD-R

There is generally more than 700MB on a CDR. I have gotten 712MB on an Imation. You need burning software that will allow you to disregard the limit and burn "long".

The Plextor drive you have will support "overburn"

You need a software like Nero to enable it.

Your results may very as to exactly how far you can overburn

this is not the exact thing you were looking to do, but it is the general idea of how to overburn

http://www.tomshardware.com/storage/...0audio-04.html

search google or something for you specific needs I am sure the data is out there somewhere or just experiment.

crankyman,

700mb cdrs typically have at most 3-15mb physically extra on the ATIP that can be used by burners and software to be overburned with varying results. That is what I understand.

Supposedly, when burning data there is something going on which will allow you to burn such large files that you would think you can't. I haven't been keeping up with such news but it's possible that 845megs on a svcd format is the "same" as 700megs of mp3 format data.

Anyways, i've seen this debate before over at Anandtech.com

yeah...there has to be some sort of compression going on. not sure what it is either....just know that the file was a 845 meg mpeg and fit onto a 700 meg cd.

it must be....magic.

cranky.

Fitting 845mb in a SVCD format is possible,because the way it's formated as a Video CD.

The same way (similar) that you can fit more than 700megs worth of WAV files on a Audio CD. I'm burning 790mb of audio information right now as a audio cd....

http://www.cdmediaworld.com

has great info on how-to overburn as well as info on each burner etc...

Thanks all.

Anyway, the 703 MB fit into the 700 MB CD-R no problem.

When burning an SVCD, you're not copying the Windows .MPG to the CD; you're copying the MPEG-2 video data. Make a CD image of the SVCD; it won't be 850 megs.

in audio or video.. size is irrelevant, as long its its under 80 minutes

in theory.. you can have a 10 gb file, and as long as its under 80 minutes, you can fit it on that cd

I'm confused.

Isn't data is data is data?

Are there any links out there that deal with this topic?

data is data....but compression and conversion ain't.

like da monkey man said....it's getting converted to svcd format. which apparently is compressed into a package that fits easily (with a little overburning) onto a 700 meg cdr.

and i'm happy that it does. i love millennium.

cranky.

Ok, so I've been makind SVCD's myself lately and I have a movie that is 144 minutes. So I could get this on two CD-R's no matter what the size of the files are? Just as long each CD has 80 min on it?

burnt as an svcd.. yes, this will take 2 cds

burnt as data.. it could take more

the differnce is when your burning audio or video, your burning in mode2 and it goes by minutes

when your burning data.. it goes by mb

Ok, so do I burn it as audio or do I need a program that burns as a VCD? I'm not looking to play it in a DVD player just on a computer with VCD software.

Just to be clear, don't confuse "Running Time Minutes" with "CD Minutes"

A 700MB CD holds 80minutes of data. With WAV audio, that's 80 minutes of audio running time. With MPEG-2, however, it could be darn near anything. Just because the film's running time is 144 minutes, it doesn't directly follow that the SVCD will be 144 minutes of CD Data. It depends on many factors, most particularly the bitrate of the MPEG-2 encode.

The easiest thing to do (if you don't want to get into the detail of everything) is just to add the MPG file to an SVCD project using something like Nero. It will tell you how many CD Minutes are required for the file. If it's under 160, you're in good shape. My guess is that it won't be, unless it's VCD.

Take an hour-long television show. Strip the commercials, and it will likely be 45 minutes. At a relatively high bitrate, sacrificing only marginal levels of quality, you can encode an MPEG-2 file (let's say about 830megs) that will translate to an SVCD (let's say about 79:56 minutes). It's the 79:56 that's important, not the 45. You cannot look at the filesize or the running time in an MPG player to find that out. Either calculate it yourself (or with a bitrate calculator) or load it up into Nero (or other SVCD software) to find the actual amount of CD Minutes required to burn the file.
