hello this is Satya from robaix and I'm
here to talk about a new plugin aura
what exactly is our aura is a reimagine
a ssin of the classic where do is plug
in for After Effects think of our like a
procedural particle system but instead
of rendering small points all over the
place
it creates vector like shapes that
change for time like the radio waves
plugin now it's very simple and a lot of
fun to play around let's go ahead create
a new composition and that's quite a new
solid that's going to apply all right
now by default you can see that there
are the circular shapes they're created
in 3d space
let's go to creat a new camera as you
can see these waves let's call them
waves these are 3d camera aver and you
have a single producer point right now
it's at the center of the composition
you can change it change the position
and
you can also change the shape by default
it's just a circular shape you can make
it more like a polygon and you can also
make it a star control a star depth or
it can increase the curvature and you
can have more than four sides for
example I can have 16 sides let's zero
the curvature drop this star and you're
not bound to just use the polygon this
is nice to have but you can also use an
After Effects mask for example let's
create a new mask here and let's change
the video tape from polygon to mask and
make sure to select the mask now if you
have multiple masks you can use old
paths but I only have one master so
we're just going to select the one mask
and you can use this mask to create
waves in 3d space now you have a lot of
settings here like in control but now
let's get to the basics first there is
this control here called frequency well
exactly the frequency frequency is the
number of waves the plugin generates per
second so the higher the number is more
number of ways they're generated in 3d
space and the lower it is the less
number of waves are generated now all
right
really let's see you crank this up
really high you can have really high
frequency so that you could have really
dance looking waves here for example you
can crank this all the way to 100 200
and you have this really dense looking
structure and and it still wanders
pretty fast
now once you start playing around you
see it's a lot more fun you can have a
little bit of spin so that kind of these
are spun over time so everything happens
here over time so the waves are born and
then they gradually changed over time
now you can set a start size right now
starts at is 0 because made when the
waves are born they're of zero size and
when their end of the lifespan they're
at the inside so every sitting here had
a start and an end for example there's a
structure and in size and there is a
start thickness and thickness and you
can also have a color gradient that can
be applied for time it starts with the
green goes to this blue and ends with
this pinkish red you can add more of
course if you want or remove them if you
want and you can sort of get the idea
here and there is also this thing called
fade-out so right now everything just
looks very sharp and very hard-edged so
if you add I would have fade in and fade
out these kind of lets you smooth out
the ends a little bit so that these look
a lot more organic and natural and right
now the frequency is really high and if
you turn it down
you start seeing individual ways for
example
and you can control the thickness it
starts at 2 and n said maybe higher so
that the lines get thicker over time if
you want and there is a few things very
important for example the lifespan what
exactly is a lifespan lifespan is
sitting there the time in seconds that
each wave exists so after they're born
and they've exist for in this case 10
seconds if you increase this the
lifespan extended gets extended a lot
later so 20 seconds so everything
happens over a longer time span
let's to the specter 10 and there is the
velocity how fast do these waves move
yeah faster it is faster waves move now
I love it a lot of this depends for
example you have a lot of waves here
they're moving really fast or you want
to slow down there's this other thing
you control to is called the time factor
time factor is how time internally ice
calculated inside the effect unrelated
to the composition so if you have a time
factor I listed this velocity back to
100 and if you want to speed this up or
slow this down if you change the time
factor everything happens a little
faster so if you put it at 2 and
generally the time runs at twice the
speed and if you wanted to happen slower
he can set it to
that's your point fire anything less
than one so everything happens a lot so
speed
now you can keyframe this and you can
actually stop at a certain point if you
want and raising the litter kind of
freezes the whole thing and the other
thing that's different from Revis is you
have a lot more things to play around
here and there's this thing called
render quality but is render quality so
by default our renders everything a
little bit noisy that's that's expected
because I think the noise adds a little
bit to the style of the plugin and and
the noise really works with this really
thin less than 1 pixel lines that can be
drawn in high frequency renders so you
can control the ripple the higher it is
the less noisy the render becomes well
you know we are aid which is actually
not that noisy and if you put it to one
it gets a little more noisy and if you
put it to like a hundred then it's
almost you can't see any speck of noise
so adjust this render quality depending
on the scene you have and usually when
you're working you might want to set
this to a lower quality by default it's
8 I think that's a good balance and if
you want a high-quality render make sure
to crank this up and if you if you have
a camera you can use the depth of field
for example just set the depth of filter
on and make sure true turn-on they'd
have to feel and you have a nice depth
of field and you can control the blur
factor to crank up Burbank town you'd
have to feel it with respect to what you
have in the camera and the layer camera
here
and that's the basics of aura and hope
you guys like aura and if you have any
further questions or anything please let
me know and thanks for watching thank
you
