Re: [Avid-L2] Consolidating Music Clips to Nexis increases their size 50% to 300%

Let it be clear that I have NO IDEA what Nexis is.
But, for math (that I can do):
From BWF to Avid MXF:
Avid MXF always splits to mono, and will add app. (very rough) 1 MB per track for metadata. (well, less, but keep that in mind.)
Then, from 16 to 24 bits, that is easy, divide by 2 multiply by 3.

Then there is something how a drive works, it works in blocks from a specific size. For media drives, a block is HUGE, and only one file can occupy a block (or can occupy multiple blocks.)

So, a gazillion small files can occupy less than a few Kb on a floppy, but take up hundreds of MB on a large block size HD.

We got audio mxf files from a music company along with  avid bins but when they consolidate the files to our nexis they file sizes of mxf audio files are increasing from 50% to 300%.  At first I though with 50% increase they must be going 16bit to 24bit but that doesn't seem to be the case.  Here is what our AE found out today.

"tried a small music clip from the drive, and consolidating to the Nexis tripled its size! 9.4MB to 33.6MB.
However, I tried consolidating the same clip to a local drive, and the size did not increase. So it looks like consolidating to the Nexis is increasing the size."

They are upgrading this Nexis over the weekend as it's very old software as it was one of the first Nexis units made.  Perhaps that will help with this issue.

Anybody seen this kind of behavior?
