Stabilization, Tracking, and Matchmotion

Stabilization:

The track that was given was all over the place as far as camera movement goes. In order to fix the final track, I had to use both a Stabilize node and a Smoothcam node.



For the Stabilization node I used two separate points to track the movement of the camera. I also made sure that my SubPixelResolution was set to 1/256 as a way of better tracking the pixels. This helped to get rid of extreme jitter in the track but was still not what I envisioned.
In order to achieve a better overall stabilization, I used the Smoothcam node. I found a point to track and analyzed it in two different ways. I found the normal way to be good, but I wanted to see what the high analyze would do, so I tried that as well. The high analyze took almost 20 minutes to complete, but I felt it was a better looking clip once this was done.

Tracking:

For Tracking I also used the clip that was given. I thought it would be funny to take a video of myself in a tank top and shorts for this cold snowy mountain environment.



After I shot this video of me outside (for better lighting), I was then able to pull the key.



After pulling the basic key, I needed to resize and roto out the parts of the background that didn't work.



I then used Matchmove node in order to place myself into the image. I found it hard because the clip that was given was of pretty bad quality. I had to deinterlace the clip in order to try make it the quality not look as bad and to get a better track. I also had a hard time trying to make my clip, which was shot in HD look as bad as the background clip.



Overall the quality of the clip limited the final output, but I was able to track the clip well and get a pretty decent looked final piece.

Matchmoving:

For my Matchmoving, I thought it would be funny to have some guns in the lab. I don't really know why I think that this kind of thing is funny, but I do.

I first shot the footage I needed of the lab.



I found some guns on Turbo squid and brought them into Maya so that I could try to get the perspective and lighting right, and to also pull a key for them.



I then brought them into Shake and used the ColorReplace, and Switchmat nodes in order to get the key that I wanted.





I then used the Matchmoving node to track the markers that I put on the wall in the original clip. I also had to use a good number of nodes to try to get the color and shadow to look correct.



The final clip is pretty good and I think is pretty funny as well.
