Mpeg1 file to DVD

[chafford100]

Hi,

Could I ask why a 2gb mpeg1 file requires 3.54gb when mastered to a DVD. Is there something I am missing.

The file is an XVCD file (same parameters as vcd but video bitrate of 1700kb/s)

I am using DVDit and a DVR-S201.

Any ideas.

Thanks,

Colin.

hehe, yeah.
I was asking myself the same question on my first VCD to DVD conversion.

The authoring software is decompressing the audio and writing it in raw PCM format on the disk.

Some of the better authoring apps will let you recompress it for the DVD to Dolby Digital, some won't.

DVDit PE does (badly), MyDVD does not, as an example.

Many thanks,

I thought that may be what is going on. What is the package to use to get round this. It seems very silly to me

if using dvdit PE you could select to convert to dolby digital 2.0 with 224 kbit(same as vcd) and the total size should not increase....but when I tried that the audio got out of synced

the only app that I have succefully made a dvd from vcd mpeg1 files is spruceup.....but it requiers that you convert the audio to 48 khz(easy with tmpgenc/toolame though)

Thanks for the tips, I now create DVD's no problem however, it takes a long time to convert the audio file even if I supply a 48kHz wav file. Is there any program that converts the wav file to Dolby Digital 2 format so the conversion won't occur.

Thanks,

Colin.
