Define what video editing software is and the basic hardware requirement you will need.


Application software that is apply in the post production of the film process, the application is used to edit the video in cuts and remove the parts that you don't need to. You will need the computer , CPU ,hard drives, cd room.


Describe the concepts of Capture, Shot and timeline.

Capture: to put information or pictures into a form that can be used by a computer.

Shot: a unit of action photographed without interruption and constituting a single camera view.

Timeline: The description of the time.


Explain basic features of what the software can do: arrange, special effects, enhancements  rendering, titles, sounds.
 

Arrange is to order the shots or capture following the timeline, the special effects can be chroma key or morphing, enhancements is to improve the quality of the image in this case video, the sound is to putting in sequence with the image so they are in the same time.






Describe the special effect techniques chroma key and morphing.

Chroma keying, is a special effects / post-productiontechnique for compositing (layering) two images or video streams together based on color hues (chroma range). Morphing is a special effect in motion pictures and animations that changes (or morphs) one image into another through a seamless transition. Most often it is used to depict one person turning into another through technological means or as part of a fantasy or surreal sequence.

1.The compare and contrast of the raster graphic and the vector graphics is that raster graphics are composed of pixels, while vector graphics are composed of paths.The raster graphic is a combination of pixel with many colors and the vector graphic composed of paths, or lines, that are either straight or curved. Both can give color or make an image. 

2.

3. The application software that can handle vector graphic are Adobe Illustrator ,Corel Draw and Inkscape.

4. The application software that can handle raster graphic are Adobe Photoshop, Microsoft Paint and Color it!

5.The advantages of vector graphics are that data can be represented at its original resolution and form without generalization.Allows for efficient encoding of topology, and as a result more efficient operations that require topological information, e.g. proximity, network analysis.

6.The advantages of raster graphics are due to the nature of the data storage technique data analysis is usually easy to program and quick to perform.The geographic location of each cell is implied by its position in the cell matrix. Accordingly, other than an origin point, e.g. bottom left corner, no geographic coordinates are stored.


7.The vector graphics rescale better because the raster images cannot be scaled up in size because they will look pixelated when printed.That's why the RASTER images have a better resolution than the VECTOR images because of the pixels.

8. One typical scenario where vector images are used is for logos.

9.One typical scenario where raster images are used is in video games, graphing calculator games, and many mobile phone games are mostly pixel art.

Scenario 1

A photojournalist covers a war. Many of her photograph show the carnage of war including dead bodies. Because the photographs cover a large amount of blood, the newspaper would be breaking the law of their country if they printed the picture. The editor of the paper suggests altering the picture to remove the pools of blood from the ground, thus, making acceptable for printing. He argues that it is better to show some of the impact of the war (by using the altered photograph) than to show no pictures of the war at all.

Advantages:

*The newspaper would avoid problems with the government, modifying the image (taking away impact).

*Prevent children from being affected by seeing these "strong images".

*Avoid military families to see what happened in the war in a strong way.

* Prevent daily becoming a tabloid newspaper.

*The newspaper will not loose ethic.

Disadvantages:

*It doesn't shows the reality of the event, (the war).

* The newspaper would not bring as much attention as a tabloid by eliminating impact on the photo.

Conclusion:

*In conclusion, we can say that it is better to remove the impact on the photo, because if they are demanded, the loss will be bigger instead of the gain, and also the ethic of the newspaper could be affected.

How to detect digital fakes?

Common logic
The logic is necessary to detect a fake photo, if something is utopia but it's in the photo probably had been modify.

Lighting
The light conditions is different from the original photograph because it depends on the place that the photo had been taken, and if you see over brightness in a photo its probably a fake picture.


Eyes and Positions
The eyes because eyes have very consistent shapes, and if someone edit a picture the eyes get distorted from the real one's and it's easy to find out the fake.

Specular HighlightsSurrounding lights reflect in eyes to form small white dots called specular highlights. The shape, color and location of these highlights tell us quite a bit about the lighting.
