[Avid-L2] CODEX Neg Image Conversion Tool to get to DNX or DPX, Terminal?

 

I've been trading emails with Codex support and they have sent me their image convertion tool.  It runs in terminal and is a command line application so I'm not very savvy of the language and syntax they are demonstrating.  They offered to log in with Team Viewer and guide me through the process but while I wait to hear back I thought I'd through out what I've got in front of me and see if anyone has any suggestions.  I'll paste the contents of the terminal window after I launch their image tool and then I'll past in the small txt file they sent as well:

   -h height    Destination image height (default src height)
   -f fps       Destination frame rate (default src frame rate)
   -n frames    Number of frames to convert
   -s scaling   Scaling type: 0 = crop/fill, 1 = to fit, 2 = best fit,
                              4 = origin top left (additive)
                              32 = medium quality (additive)
                              64 = high quality (additive)
   -o options   Dest filetype options (comma separated list)

   rgb16        16-bit RGB
   yuv8         8-bit YCbCr
   yuv10        10-bit YCbCr
logout

[Process completed]

Now here it the imageconv-usage.txt document they also sent me:

Examples:

To convert a single compressed DPX into a RGB 10bit DPX
Low Quality:
F:\material>imageconv.exe -n1 -o rgb10 srcdir\test00005.dpx dstdir\test00005.dpx
Converting 1 frames...
00000 F:\material\srcdir\test00005.dpx

High Quality:
F:\material>imageconv.exe -n1 -s64 -o rgb10 srcdir\test00000.dpx dstdir\test00000.dpx
Converting 1 frames...
00000 F:\material\srcdir\test00005.dpx

To convert a sequence of DPXs just specify the first image file. If you don't include the -n option then it will automatically figure out the sequence length.

F:\material>imageconv.exe -s64 -o rgb10 srcdir\test00000.dpx dstdir\test00000.dpx
Converting 360 frames...
00359 F:\material\srcdir\test00359.dpx

F:\material>imageconv.exe -n100 -s64 -o rgb10 srcdir\test00000.dpx dstdir\test00000.dpx
Converting 100 frames...
00099 F:\material\srcdir\test00099.dpx

To overide the DPX framerate use the -f option. This is useful to convert the timecode metadata from a highspeed/field based SMPTE timecode.

F:\material>imageconv.exe -n1 -f24 -s64 -o rgb10 srcdir\test00000.dpx dstdir\test00000.dpx
Converting 1 frames @ 24 fps...
00000 F:\material\srcdir\test00001.dpx
