Hi,

 

Just a quick update related to the import PVN module at
http://www.transcoding.org/transcode?Import_Modules/Import_Pvn 

 

The PVN file format does not support Audio.  It was designed for scientific
use and is an uncompressed video only format supporting floating point #'s,
signed, and unsigned integers.

 

Example usage (from our internal docs):

Example shellscript to convert a whole directory of PVN's to uncompressed
AVI's
(flipping vertically, may need to swap B/R channels for colour: add -k):

for i in *.pvn;  
 do 
  PREFIX=`echo $i|sed -e 's/\.pvn//g'`;  
  transcode -i $PREFIX.pvn -o $PREFIX.avi -x pvn,null -y raw,null -z -V
rgb24
done
