Problem transcoding Cineform to DPX using cf2dpx

I've tried exporting a 4197 frames long CFHD avi file with cf2dpx using this command line:


cf2dpx Y:\DPX\CFDPX\TRAILERDPX.dpx 0 Y:\DPX\TRAILERCFTODPX.avi


The problme is that the converter transcoded and replaced 4197 times the same file name with no added number and I ended up with only 1 TRAILERDPX.dpx file size of 7K.

I've transcoded with After Effects 7.0 with Cinenon DPX and had correct transfert of about 27 GB final size.

What did I do wrong with cf2dpx and which is better the After Effect or Cineform DPX ?

Thank you.

type cf2dpx alson on a shell and it will tell you how to use it. Here is the help you get

Usage: cf2dpx source.avi|mov output_template.dpx [switches]
switches
-iX - input frame number X
-oX - output frame number X
-dX - duration, extract X frames
-bX - base frame count for the sequence (name = base + start)
version 1.40 18-February-09

example: cf2dpx M:/source.avi M:/sequence%05d.dpx -i134 -d24 -b10000

dpx naming: basename%0xd.dpx -- 'x' is number of digits the count
e.g. "seq%05d.dpx -b400" produces seq00400.dpx, seq00401.dpx, ...
"clip-%03d.dpx" produces clip-000.dpx, clip-001.dpx, ...

This is a newer verion than what you seem to be running, but in either case you didn't offer a naming template for your DPX outputs, you told it to put all the frames into one dpx file. You template should be Y:\DPX\CFDPX\TRAILERDPX_%05d.dpx -- this will get you TRAILERDPX_00000.dpx through TRAILERDPX_04196.dpx
