hey everybody welcome back with a new video my name is Jamie Luik you might
know me from the YouTube channel Film Empire or the stabilization tutorial I
did on this channel a while back you all really seem to enjoy that video so this
time I'm back to talk about keyframing and the value graph keyframing is
insanely useful for editing and compositing I use this function in
literally every single video I edit if you don't know what key framing is
let me explain key framing is the ability to change a parameter's value
over time for example you're watching this video at 100% scale but I can
keyframe it to make the footage bigger over time now this is a basic function
of the HitFilm software in this tutorial I'll show to you and HitFilm Express 14
to start key framing in HitFilm select a property with an open circle before it
if you click the icon it changes meaning you can start key framing if you click
this icon again it will remove all the key frames on that property you can do
this on the clips transform properties for example but many other effects also
support this if you were to go to a certain point in time and change the
value of the property your keyframing you can see that HitFilm places a
diamond mark on the timeline instead of changing a value you can also hit Alt+T
which adds or removes a keyframe on the frame you're on in this example I'll set
a scale keyframe here by using Alt+T move forward in time and adjust the
scale which causes hitfilm to automatically create the next keyframe
if I play the clip back now it zooms in in a linear manner this makes sense
as the standard keyframe type is linear but if we go over here above the
timeline you'll see that there are five other types this is where the value
graph comes in you can use this on both the editing timeline and a composite
shot I'll show you both of those in a second here is a composite shot with a
clip I added and the scale keyframe to zoom in if I click the scale property
and turn on the value graph with the button over here a straight line appears
the value graph visualizes the keyframes and allows you to make adjustments you
can turn on the value graph from the editing timeline by clicking this
timeline icon in the controls tab and clicking this button here make sure the
controls tab is wide enough otherwise the button might not show up in the
value graph you can drag a keyframe up or down to change its value while
dragging it left or right changes its position in time a property with
multiple values shows up on the value graph as several colored lines to
differentiate between them the steeper this line is the faster the change of
value I'll select both keyframes and set them to the next type constant as you
can see the value stays the same until the next keyframe takes place this is
particularly useful if you need something to move in the time span of
one singular frame next up is smooth this gradually speeds up and back down
again giving a very nice start and stop to the movement
you also have smooth in and smooth out which only smoothes one side of the
keyframe if that makes sense the last option is the manual bezier which at
first looks a lot like the smooth curve but it ramps up in speed a bit faster
smooth smooth in smooth out and manual bezier all have handles to the keyframe
allowing you to fine-tune the shape of the curve to get the motion you want to
reiterate the shape of the value graph changes how the parameter changes over
time a line will give a constant change while a curve like this starts out very
fast and slows down to get to the final value try out some different settings
and see how this is different from this
