Hi,
over at Doom9 some interesting tests were made:
http://forum.doom9.org/showthread.php?s=&threadid=31301&perpage=20&pagenumber=7
The problem is that dark areas look bad (kinda dirty) when played back
to TV. This seems to be prevented by setting the luma offset to -2,
which darkens the movie a little, but in the end (even with luma
masking!) looks close to perfect on TV. (maybe some more tests with
different movies should be made, but Iago tested it on 2 different
movies already and this small offset seems to be enough).
I think it wouldn't be too hard to code that into XviD itself, with a
flag called "XVID_TVOUT" or something similar this could be activated.
What do you think?
Best regards,
Koepi
