Blu-Ray Size/capacity Dilemma

[JAC99]

Hi All,

Can anyone suggest an answer to this sizing dilemma which I am currently facing?

I have three files each in a MKV envelope; File 1 is 1,274,975 KB; File 2 is 1,509,086 KB; File 3 is 1,471,251 KB. Total size is 4,255,312 KB.

The files in the MKV envelope are probably compressed and will therefore be larger when extracted.

Using MyDVD to put together a disc, the three files, according to the capacity bar, use 10.5 GB before I add any menu, audio etc. This leaves plenty of spare capacity on a 25GB Blu-Ray disc.

 

However, if I carry out the same excercise using Nero 11, at the same point of loading the three files, its capacity bar shows 35 GB being used.

 

So what is going on? Are their extraction routines so different as to give such diverse figures? What happens about the final quality of the videos. More is usually better therefore will Roxio produced discs be lower quality than Nero produced discs?

 

Any suggestions gratefully received.

TIA

John

 

PS I am using Roxio Creator 2012 Pro with the Blu-Ray add-on.

Look at the bit rate of the files. That is probably where the difference is.

What project settings are you using in Roxio and Nero?
