sorry for the top post. didn't realize that was part of the etiquette and
didn't even know what top post meant.
Erik,
As far as fast importing into avid i have been able to do this with avid
7 and 8 with the method you just described, right-click in a bin choose
import and just select what drive you want it to copy the media. It does
the fast import, re-wrap no transcoding. This is the command i use: 'ffmbc
-i <input file> -r 29.97 -target imx50 <output file>.mxf' - make sure you
end the output file with '.mxf'
Although ffmbc also supports XDCam it always errors out on me because there
aren't 8 channels of audio. imx50 works fine for my purposes. The only road
block is ffmbc doesn't open webm videos and a few others. Thats why i'm
trying to use ffmpeg to decode and pipe it to ffmbc. Also i've only tried
this with standard def material. don't know what will happen with high def.
I"m working from an archive
