De cette
manière vous pouvez appliquer un seul effet
à plusieurs clips en même temps, c'est à
dire que pour un clip on va appliquer un
effet particulier, puis le clip sélectionné
on va choisir dans le menu contextuel Copier->Effets
puis on sélectionne les autres clips
comme vu précédemment, puis toujours en
maintenant les clips sélectionnés, avec le
menu contextuel on clique sur Coller,
et l'effet du premier clip avec ses
propriétés se retrouvent appliqué sur les
clips sélectionnés.
Note
that by selecting a clip and from the
context menu View->Show
waveform, it
allows you to visualize the sound
volume of the clip. We will use this
function to pace the sequence of clips
according to the rhythm of the
soundtrack. To do this, we will
display the waveform of the
soundtrack, the principle is to
position the cursor during a change of
rhythm and we place the passage from
one clip to another in the same place,
in this case it is not necessarily
necessary to put a transition, a
sudden passage from one clip to
another punctuated by the soundtrack
goes quite well.
Still
from the context menu, you can create
an animation at the beginning or end
of the clip or even over the entire
duration of the clip. This animation
will allow you to zoom in or out or
translate the image.
Note
that if you add an animation with
reduction or displacement of the
image, the video will be completed by
a black background. On the other hand,
if there is a clip on the track below
as in the configuration below, in this
case it is the clip of track 4 that
appears instead of the black
background.
From
the same menu it will also be
possible to rotate clips, be careful
in case of rotation of 90°, black
bands will be added on both sides.
Otherwise you can from the Layout
menu arrange a view with 4 different
clips, for this they must all
overlap on different tracks, the
first will be at "scale 1/4 - top
left", the second at "scale 1/4 -
top right", etc. This is basically
what we call a split screen.
Otherwise, still from this menu, we
can play on the speed of the clip, in
normal speed or can scroll it
backwards at x1 speed, in fast mode in
accelerated forward or accelerated
backward (from 2x to 16x), or even in
slow speed forward or backward (from
1/2x to 1/16x). The Freeze
& Zoom
command is also interesting because it
allows you to freeze the image and
zoom it little by little, it gives a
nice effect.
We
saw previously that we could add fades
and animations, by default they have a
fixed duration, we can play on that,
by making the properties of the
selected clip appear. In the image
below, we have an audio fade in and by
moving the cursor from the first to
the last green line we see that the Alpha
parameter goes from 1 to 0.
If
the duration is not sufficient or on
the contrary too long, we will move
the cursor to the place where we would
like to see the first green dash. Then
at the Alpha parameter level, we will
make the context menu appear with the
right click of the mouse and Insert
a keyframe. On
the image below, a third green line
has appeared under the red line of the
cursor.
Now
we must consider that the first green
dash is the 1st keyframe, the second
the 2nd keyframe and the third the 3rd
keyframe. For the 1st keyframe we will
put a value of 1 for Alpha , we
can delete the 2nd keyframe which is
no longer used and put a value of 0 to
the 3rd keyframe. In fact we will have
extended the duration of the fade. To
obtain an even finer management of the
progression between the keyframes, you
have the choice between a Bézier or
linear curve.
Note
that this keyframe principle also
applies to most of the properties
settings as well as those of
animations, effects and transitions.
Below we find the properties of the
transition Tournoyer
34
which is configurable via keyframes
and the Brightness
parameter.
