VIDEO: RECORDING AND EDITION

The subject goes on and a new work is coming over. The objective is to do a video, starting on the thought of ideas and finishing on the distribution, in this case to the professor of the subject.

The first idea is to shape the message and the vision of the recording, a work usually done by the directors in the films. In our case, after thinking the values we want to share on our video, we have to think who is going to appear on it as if it was a casting. This is indispensable to transmit our message correctly.

When everything is ready, we start to record applying all our knowledge, as for example the rule of thirds. And once we obtain the recording we edit it so that we can transmit the emotions and the values we want. We can also apply music to get better results.

Now you can see an example of the video edition. The quality is quite poor but we can perfectly appreciate the edition work:

COMPUTER GRAPHICS

When we listen about computer graphics nowadays we have no problem to relate it to our lives. Everybody has seen a video game, a film or even series with this type of design. Computer graphics are based on the edition of models and figures that can create, store, modify and render by pixels on the screen the edition.

At first, there were invented for military reasons but the development of the techniques had extended the opportunities to other uses as the ones named before.

For this editions the most simple transformations for a 2 dimension or 3 dimension model are the next ones:

1) Movement (lineal): to change the position of the model to a new one by a vector. (Example of a 2D figure)

2) Scale: for changing the size of the figure. (Example of 3D)

3) Rotation: used to rotate a model in a circular movement around an axis for a defined angle.

      [R] = rotation matrix

{x'} = [R] {x}

Here is an example of a rotation from the mechanics II subject:

They are asking us to rotate the first piece (A) so that it meets with the second one (B). Which is the rotation matrix R and the rotation angle?

IMAGE EDITION (Speech)

Another Thursday receiving a new lecture focused on the images, more concretely on the edition. Firstly, we were talked about the image and its properties. Resolution, format or features like the picture quality were introduced as the first contact with the theme.

A good brand of applications used to edit images were also presented, but the explanations were concretely for GIMP, a similar software to Photoshop. Changing some small features as contrast, colour line or the "varita mágica" to get the best of our pictures. After those changes we can see much better the object in the image and it only appears what we want on our picture, without anything else.

Now we can start editing our images and adapting them to our presentation!

HELP YOUR SPEACH WITH A EFFECTIVE POWERPOINT

New interesting lecture of the subject, this time talking about how to make a effective presentation. We are used to receive a PowerPoint lectures or to have to hand out some presentations. But are this presentations effective or can they cause death by PowerPoint?

It is not so difficult to do it attractive for your listeners, the key is not to extend on your text, neither using bullet point. This type of presentations can cause death by PowerPoint, while everybody is really bored and without paying any attention to the speaker.

Presentation must be more direct, with a picture that represents what you are talking about and one or two words for a better understanding or even to follow the speech without problems. A easy and simple presentation combined with a well-prepared speech for a effective connection with the listener.
