[FFmpeg-user] recursively convert subfolder sequences to .mov?

Hi Paul,

Thanks for the reply.
The closest I got to something that works is this:

/Applications/ffmpeg -f image2 -pattern_type glob -i '/Volumes/reel1/shot1/*.dpx' -r 24 -vcodec prores /Volumes/reel1/shot1/shot1.mov

What I'd rather be doing is processing all of /reel1/*/*.dpx

to find any #########.dpx sequence in each directory, to then create 

/Volumes/reel1/shot1/shot1.mov
/Volumes/reel1/shot2/shot2.mov
/Volumes/reel1/shot3/shot3.mov
/Volumes/reel1/shot4/shot4.mov

this helped:

but I still have to change the name of the input path, output path and filename on a per folder basis. 
I did 15 last night, 1 at a time, but it's gonna be a drag processing 130gb per reel like this. 

I wish my perl scripting was up to bar [or existed in the first place] because this is probably cake.

My friend Matt said the following:
-generate list of directory names
-foreach directory in your list
   - count how many things there are that you want to do something with
   - for each thing
        -fill in the blanks in your command line template
        -call the command on the command line to Make it Happen
