Press [tab] to add a node of your choosing.

Press [F] to focus on any selected area such as the screen or a node

Assign your nodes by numbers in order to shuffle between them

I can shuffle between selected nodes by pressing their assigned number.

I added the following nodes to experiment on.

I added a “transform” node by pressing T or T while a node was previously selected so the transform will by default link to said node.

I used the transform node to move my color wheel around in the viewport.

I added a blur node and gave it an increased value on the color wheel’s edges by picking the “gaussian” setting.

Press [S] on the properties panel to check the render properties of your scene.

I added my video of independently moving candy pieces.

To begin “rotoscoping” I added a “copy” node using [K] and a “Roto” node using [O]

With the Roto node selected I equipped my “Bezier Pen” tool to draw where my mask was going to be.

The alpha channel of my mask.

I can also used a rectangle masking tool.

Next, I picked a frame where the video had the least movements so the Roto mask can work more effectively.

I traced my shape around my object.

[M] to show overlay for a clearer trace.

I set my key frame at the end of the timeline.

I set my keyframe at the start.

My initial scene: I needed to develop a technique to effectively rotoscope the man’s hand.

This was where the hand in the video had the least motion- hence where it was going to be the easiest to begin rotoscoping.

Dividing the hand so I can rotoscope individual shapes on it was the way to go. Too much points in a rotoscope would cause a jitter effect in my video.

Rotoscope using the “B-spline” pen according to my theory of dividing my hand (and fingers) into different parts to rotoscope.

Control to and drag to select multiple points.

My main image

The sky image asset

Pressing [Y] activates “Luminance” vision.

I added a “Keyer” node to create and adjust my alpha.

My node tree so far…

I rotoscoped the area I did not want to fall under the effect of my sky asset.

I inverted my keyer’s selection to adjust the white values in my alpha.

I added a merge stencil to separate my alpha

I added a “garbage” rotoscope node to get rid of unwanted alpha that was in my original image.

The final result

My goal was to color grade the women and not the background.

Viewing my images with heavy blur really helps me distinguish the different colors in an image.

I viewed my LUMA levels [Y] to make it so that the aperture slider diminishes all the blacks in my image at the same time.

Before

After

I wanted to clean this uncanny shade.

To take a step further, I rotoscoped the windows and key framed my multiply node under each separate grade node connected to its separate rotoscope node.

Note: do not duplicate the rotoscope node to use it on another grade. Rotoscope nodes retain data and unless you remove that data, the graded colors will mix.

Starting point

Result

The gray area is not tracked properly in this scene.

I want 2 tracking points to rotate alongside their designated buildings in the scene.

I wanted to track the car’s wind sheild.

This is the “Rotoscope Paint” tool.

I added a tracker so the previous effect can be applied to all my scene instead of just one of its frames.

I needed to get rid of the old man in the red circle.

I added a tracker to track the scene’s movement around him.

After adding the “Frame Hold” node, I was able to freeze a later on frame in the scene in which the old was not present.

I Rotoscoped the area I wanted to cut out.

It worked. However, the women which I wanted to stay in the scene was affected by my Rotoscoped area.

My node tree up to this point:

I added a multiply node and keyframed its value at the point she went in the roto and right afterwards.

Since the Rotoscope step, I had uneven noised in my scene as shown in the “Blues” view. Note: the last color the human eye sees is blue.

I tracked my uneven noise area with the “Denoise” node’s tracker. Then, I added a noise node and adjusted its settings.

Before

After

My final node tree.

I needed to use a “Planner” Tracker to get rid of the people in this video

I rotoscoped the shape near the people so my planner tracker will recognise how the video moves around them.

The corner pin node is my tracking node.
