codec changing when transfering at DVinfo.net

Cees van Kempen · December 30th, 2010, 04:59 AM

When I check the info of a clip shot with a nano (on my EX3) and backed up in a nexto it says (for example):

Codecs: XDCAM HD422 720p50 (50mb/s), Integer (Big Indian), Timecode

When I transfer the clip to my brand new Mac Pro the info changes to:

Codecs: MPEG-2 Video, Linear PCM, Timecode
Color Profile: HD (1-1-1)

Questions:
Why does the codec change?
Does it matter?

But does it really change? It seems to me like the two are saying the same thing in different words. Or at least are looking at different things about the codecs.

XDCAM HD422 uses MPEG-2 video compression, 720p50 (50mb/s) is HD, and linear PCM uses integers.

I agree with Adam.
There is no contradiction between both infos.
The only difference is probably on the different software that is reading that info on both devices.

Hello Ces

Might I ask what you are using to view the information on the Old Mac to the new?

This would probably narrow down the change in term's.

Could it be Quicktime player 7 on the Old Mac and Quicktime Player X on the New?

Thanks

Andy: The info Cess is seeing is from the OSX Finder, using the "Get Info" command. (Select the file on the desktop and then hit clover I).

Cess: As Adam and Rafael have pointed out, nothing is changing with your nano file, just the different words used to describe the same thing. If you open your nano file in Quicktime Player (either the Quicktime 7 player or the Quicktime X player), and use its "Get Info" command, you'll get much more info about the format of the file.

Guys, thanks for your replies. Indeed it seems to be other words for the same, so nothing to worry about.
