How much can the CD contain ?

[proctor]

Hi,
I've been reading a few articles on CDs and how much then can fit with Mode2, Form2, but some of the things that I've been reading are to technical for me and I don't understand them. Can anyone make it more simplified for me to understand? For example, "hey Possessive dood, 720mb is the max for 700mb VCD and 820mb is the max for 800mb VCD". By saying VCD I mean when I'm burning a VCD onto a CD that is XXXmb.
Of course if you have any personal experience to tell us all about, it could start a kewl chat in this thread too
Thanks

When I do a DivX to SeVCD i can get 822mb on a 80min cd. You can also overburn depending on your burner, but only by a few mb at most. if your cutting(multi-plexing) w/ bbmpeg set the size to 790mb and it will make the output 820mb.

So you're saying that I can fit a 822mb file onto a 800mb CD, right?

You can fit 822 MB on a 80min/700MB cd, but only if it's a (S)VCD,
not data.

Don't you mean a 800mb/90min CD ? I don't think that you can fit all those MBs onto a 80min/700mb CD ...

Yes you can, as long as its a video file, not data!!!!!!

You can fit approx. 78 minutes at a compliant VCD Mpeg 1 standard., etc.

Look to the LEFT under VCD and SVCD at the tops of their pages...

As far as the SeVCD/SxVCD thos will allow more due to the varying bitrate of the streams which are allowing it to "dip" well below "standard" formats

proctor, you can fit 800mb of VideoCD Standard into an 80min/700mb CDR.
And you can fit 900mb of VideoCD Standard into a 90min/800mb CDR media.

It's not a trick, it's not magic, it's well in the standard formats.

i regularly put 950+ mb on a 850mb cd when making vcd's from mpeg1 video's 8)

[Sefy]

850mb CD ? wouldn't that be a 99min CDR media ? I know that 90min is 800mb, and 99min can do around 870mb, but I haven't seen any 850mb CDs

The "volume" of a CD is as a standard measured/declared as the "amount" of computer data bytes. Computer data are for instance word files, excel-file, etc.
Burning a CD the burning program splits the CD up into a number of blocks (imagine small squares like on a sheet of squared paper).
For each block the programm allowes to fill in a maximum number of bits and bytes of computer data.
But for video-data (video bytes) tyhe program allows a larger number of bytes (almost 15% more) per block. So it is no magic, but a question of measuring data-bytes or video-bytes per block and CD.
The number of minutes (for instance 80 min) is just made to confuse us even more: it indicates how many minutes of music in standard .wav-format you can store on the CD. By coincident it almost equal to a mpeg-1 stream, means you can store up to 80 min mpeg-1 (VCD standard) on this certain CD.
Confused?

if your cutting(multi-plexing) w/ bbmpeg set the size to 790mb and it will make the output 820mb.

i set my filesize for a vcd to be 790 mb but it came out to be 824 mb. instead of 820.
not a big deal but should i overburn?[/code]

[Sefy]

Only overburn when you know your CDRW and CDR media support it, and only when you are aware that it might damage your drive or media.

i am sure that my drive/cd-r media support overburning. i heard somewhere that you could actually fit 845 mbs on a cd and i have fit 833 on a SVCD before. what is the deal about the vcds being compliant or not. doesnt it still burn in mode 2 even if its not standard compliant VCD?
like i said before, my file is 824 mbs. so is it even nescessary to overburn?

[Sefy]

The VCD Compliance is just if your DVD doesn't accept non-standard.
As for overburning, yes, 824mb is 24mb over size, which is 2.4min more

[e-z-e]

how is it that i didnt have to overburn with a SVCD file that was 833 MB...9 more than the 824 on this VCD?

[proctor]

I don't think that I'll ever really understand all these calculations ...
