3D Tracking: projection and removal

Posted on 26th February 2021 by Gherardo Varani

1 Markers removal: I rotopainted the markers creating tracked patches into the 3D scene

Screenshot of the original sequence (with markers)

3D view: one camera is not moving being the projector while the other is moving forward.
Patches are located exactly on the selected points

I 3D tracked the video and removed some elements from the scene.

Another way to create and apply elements to the tracked scene is using PointsTo3D

3D Tracking

Posted on 9th February 2021 by Gherardo Varani

Tracking a 2d video to create a 3D environment. I have applied to the plate axises and cards in order to make visible the 3d space.

I have issues when I create the camera, it always appears under the ground level…

2nd video, two cards applied on the walls and few axises around to make the 3d environment visible

3D ENVIRONMENT

Posted on 1st February 2021 by Gherardo Varani

Starting from a 2d image, I recreated a 3d space: through use of cards, projected into a scene from a camera, all connected to scanline_render.

VFX showreel Term 1

Final reel

Posted on 11th January 2021 by Gherardo Varani

In this plate I tried to use most of the tools I have learnt during the first term using Nuke.

I first stabilized the footage and then I denoised it in order to track it way better. After that I started to rotoscope the main character because I want her always to be in front of everything I have added to scene.

I did some color grading, white balance and color-matching with all the images and videos that I added to the scene.

The original plate had some details which I didn’t like, for example some stains on the walls, tubes, people and signs. So I did some clean ups and replace where I could.

Clean UP (rotopaint)

Posted on 14th December 2020 by Gherardo Varani

First exercise: clean up

From this plate I want to remove the slippers from the ground in the foreground

The problem here was that the clean up shape was continuing going in the scene

This plate was complicated due to its movements and changes of prospective

I have removed the cars on the right and some elements in the field

CornerPin & Planar Track

Posted on 6th December 2020 by Gherardo Varani

FIRST EXERCISE

I tracked the three spaces with Planar Track and CornerPin allowing me to match the three posters.

VIDEO 2

Original Plate

Using PlanarTrack I tracked two areas of the scene, applying then the two elements (graffiti and the big yellow sign)

VIDEO 3

Original plate to stabilize and track (cornerpin and planar track)

Here I added several elements:
Starting from the left I added a bansky graffiti using planar track, the element is located below the pole (as it has been rotoscoped). Then I applied the mandalorian poster with cornerpin which is below Antoni (rotoscoped), letting the black lives matter sign emerge from the original video and the anarchy logo of bansky. Finally on the floor is the number 2020 applied with a corner pin, placed underneath the walking Antoni
