[Cin] "color hell"

Finally I managed to patch! On Phyllis' suggestion I entered the
absolute path of the files to patch every time it didn't find them.
Below is the test I did.

I downloaded the app mentioned from the link and created a video on
smartphone; as mentioned in the link the video produced is: YUV,
NTSC,color range:tv; primaries=BT 601 PAL; Transfer=BT 601 and
Matrix:BT 601 (a horror in this day and age where broadcast worldwide
uses HD and rec 709). In CinGG without patching you have a slight
change in brightness going from 601 to 709 and vice versa (correct is
601!); you have a bigger change going from Mpeg to Jpeg (correct is
mpeg!).
Applying the patch and importing the same video as before you have
some difference between BT601 PAL and BT601 NTSC (correct is BT601
NTSC). Both are different from BT 709. Thanks Andrew, you did a great
job for me!

In CinGG, to make a transcode there is the excellent ColorSpace plugin
that works just for these changes of color spaces.
I once asked if it was possible to integrate it into the "Transcode"
function so that it would work for all project sources and not just
the edits to which the plugin applies. But I think it's a complicated
job....
