Andrea,
I must be doing something wrong?  I loaded a small 1.5 minute video and rendered it using DPX.dpx and it only created a single video file that was all black when I used ffplay to play it.   Mediainfo shows:

I tried to make an ffmpeg profile of the DPX standard movie format. So
now CinGG has DPX support inside ffmpeg and OpenEXR outside of ffmpeg.
Remember that these two formats produce a sequence of still images and
their relative TOC (it is only the TOC that needs to be imported into
CinGG when we want to load this format). So it's good to create a
folder where to put all the images and the TOC produced, which are
hundreds and even thousands. Big space occupation but super efficient
in timeline and great quality.
I attach the profile if you want to test it.
