Week 8 Exercise

Task 1: Motion Tracking

For this task, we had to import a video of the CI precinct and add a piece of text, then try and get it to stay in the one place throughout the video. This is motion tracking.

Firstly I had to open the Tracker window. This then allowed me the option to track a certain part of the video. I was told there needed to be a lot of contrast so it was easier for the tracker to pick up a point. I chose the top of a building where the buliding was relatively dark in comparison to the light blue sky. We then had to apply the tracker. After this we put a text layer on and made sure that it was to pan behind. If the confidence of the tracker was relatively high, then the text should remain fairly still.

The text on my video, for some reason, moved around a little bit, even though the confidence was 99.6% so I'm not too sure why that happened. I found this tutorial quite helpful and learned quite a bit. I wasn't overly impressed with my end result, but I realise that with after some practice and experimenting, I could get the text to look a part of the scene.




Task 2: Corner Pinning

For this task, we had to attach a picture to the screen of a computer and get it to stay there through the video by using corner pinning.

I found this exercise quite easy as it was pretty much the same as the previous one, apart from the fact that in the tracker controls we had to select perspective corner pin under the track type section. This would give us four corners to which we pin to the corners of the computer screen.

The most difficult part of this exercise was getting the pins to stay in the corners of the screen, and it became a very tedious job of having to go through and fix up the errors that the tracker made by physically going in and repositioning the pins.

After this, we were to apply the tracking to the picutre we chose. After this it became ur job just to try and get the picture to look as though it was on the screen. To do this we applied motion blur and even feathered the outside of the image so it was harder to see the screen.

I wasn't too pleased with how mine turned out, because even though the tracking was good, it jumped around alot. And even with the motion blur and feather it looked too fake to be on the screen of the computer. However, I was pretty happy with what I learned in the tutorial considering it was my first attempt at motion tracking and corner pinning. I guess I can only get better.
