Hi, I'm Mike from how to shoot and edit -
today we show you how to add Motion blur in
Post.
Add Motion blur in After Effects CC
To get the most natural looking motion blur
in your footage your shutter speed should
always be twice the framerate which equals
a shutter angle of 180 degree.
In bright daylight that can sometimes be tricky
to achieve.
So you have to close the Iris or bring an
ND filter to get the right exposure without
changing the shutter speed.
But what if you don't want to close the Iris
or you have no ND Filter with you?
Well you have to choose a faster shutter speed
then and your footage probably looks a bit
choppy, because it lacks the natural motion
blur at fast movements.
Here is the solution to add the motion blur
in post and simulate the shutter angle of
180 degrees.
Here we have our clip in Adobe After Effects
CC.
Let's select the clip and go to effect � time
� CC force motion blur.
Now let's look at our clip again with the
standard settings.
Here you see After effects trying to create
the motion blur, but it looks wierd, because
After Effects has not enough frames to work
with to make the result look good.
So � next we enable frame blending for all
layers.
Then right click on our clip � frame blending
� pixel motion - or click two times on the
little frame blending box besides the layer.
Now it looks already much better.
Next we change the Motion Blur Samples in
the Effect Controls Panel to at least 20 to
make it a little smoother � and - our footage
looks like it was shot with the correct shutter
angle.
