The doc says : "The track with the background should be muted and
underneath the track with the action and the colormodel should have an
alpha channel."
I don't really understand "and underneath" ??? As it's muted, I could be
12 tracks further, there's no influence...
Anyway, I followed those recommendations.
My project format is RGBA-8 Bit as I guess "A" means alpha channel...
Well, nothing happens, I still see my budy walking, the background is
still there... I surely missed something :)
Ok ok, sorry, nice self-reply, but stay tuned as these reflexion will
surely help other fighters.
Some more minutes of tests lead me to discover that :
- it's working
- it's working very poorly
- underneath means "relatively under", not "directly under". The
background track may perfectly be 42 tracks below, but it has to be below
- muted does not mean "the button that makes a track play or not", but
faded to 0%
Having saw that, I'm pretty sure there are lots of things I still don't
understand :
- what does really means mute (the 'm' shortkey has no effect)
- what are the best lightning states to hope experience the best with
difference key
- is difference key a viable alternative to green screen...
Hi List,
Still self-riplying, thinking that it anyway might help others.
I finally had some success and achieved what I was looking for :

- In this test case, the background is played but muted, that is to say
the small icon "don't send to output" is barred.
- About the lighning, I think it really did a difference, and a strong
lightning did help
- the settings to obtain a correct diff key are very sensible, and I'm
sure the usage of green screen technics are much more simple.
Considering this, I guess diff key can not be a serious alternative to
green screen, but may be of some help sometimes.
See you.
