During this short project, we were tasked with creating a VFX effect using NukeX to add graffiti onto part of a video of our choice. For my scene I chose a piece of stock footage walking backwards through an alleyway and I chose a piece of graffiti created by 'Banksy'.
Firstly, I took the footage and added it into a NukeX project. Then, I created a rotoscope planar-tracker. I also used a CornerPin absolute alongside the roto, as I then tracked the roto to the side wall so it would remain in its position, changing rotation and size to fit the area more effectively.
Next, I created a rotoscope around the image of graffiti to remove it's background and make it fit into the video more effectively and blur into the background better as well.
After creating the roto, I added the image back into the video and checked how it blended into the background before deciding to improve the graffiti's Alpha matt.
In order to improve the graffiti's ability to blend into the background, I used a keyer node to remove more of the lighter colours from the image's Alpha, making it bend much more into the background, removing the more cartoonish appearance of the image for a more realistic blend of the image and background.
Overall, I believe I did well on this project because the graffiti image blends well into the final video as it appears realistic and blurs into the wall behind it. However, if I could improve this project I would further improve the blend and blur of the image into the background so that no difference in texture could be seen without specifically looking for it.
