Edit Blu-ray Audio in VMW5

[danswano]

Hello,
I have some blu-ray titles i want to edit using Video Mastering Works and i have to do some audio edits so i have to export the audio through the app as well.
The apps is only offering DD and LPCM.

The original audio track is 7.1 DTS-HD.

The question is:
Is it ok to export 7.1 LPCM instead of 7.1 DTS HD? will i be loosing something or gaining something?

Thank you.

LPCM is uncompressed, DTS HD is lossless compression .

So the file will become larger in filesize, but there will be no losses from lossy compression

So let's say that the DTS-HD audio track has a 3 giga bytes of size, how much the LPCM would be?

Impossible to predict, because different audio content has different rates of compression

Try it and find out

Thank you for the info.

That's not hard. DTS or DD or whatever will be uncompressed and become LPCM, which is CBR. So program length x no. of channels x no. of bits x sampling frequency / 8 = total size. A 100minute 7-ch 16bit 48KHz LPCM track would therefore be about 4GB, regardless of where it came from or what format it once was.

U will only be able to decode dtscore 5.1 with vmw5.
