(Title, Credits, animated captions, stings, The sting has no real use of text besides the e4 logo.
indents, interactive menus, web banner)
Brief description:
What do you see? You see a very purple background with some white of some houses. Something is stood in the
road as a small thing comes past and turns it into the E4 logo, the camera zooms out and there
are lots of E4 logos all along the street.
Techniques used:
Animation, Visual Effects, Colour Rendering, Animation is used all throughout the sting and the purple colour effect is also used a lot in
Graphics, Movement correspondence to the logo. The visual effects involve zooming out and movement of the
character and the transformation of the e4 logo.
Advanced techniques: There is a weak blur effect used in the whole sting but the E4 logos are sharpened.
Blur, Sharpen, Distortion, Rotation, Opacity

H.264 is also known as MEPG-4 AVC. H.264 uses the latest innovations in video
compression technology to provide consistently crisp and clear video for the best possible
viewing. 1

Pros
H.264 delivers incredible video quality at data rates one-fourth to one-half the size
of previous video formats
H.264 offers dramatically lower bit rates and better picture quality than MPEG-2,
MPEG-4 or H.263+
It is 2X times more efficient than MPEG-4. and file size is 3X times smaller than
comparable MPEG-2 Codecs
It is easy to integrate and covers wide range of picture format. Hence used in large
application segment.
Cons
H.264 requires longer encoding time
It is certainly not constricted and low-bandwidth friendly
More Hardware overhead is also one of the limiting factor
Licensing agreements are complicated.

Motion graphics - Graphics that use video footage and/or animation technology to create the illusion of motion or rotation, graphics are
usually combined with audio for use in multimedia projects.
Compositing video - When there are several different clips of video are layered over one another to create a single image.
Interactive Menus – DVD Interface or Interactive Menus on a web page
Ident – The ‘call sign’ of a channel or production company to identify themselves on screen, usually shown before a programme.
Animated Captions – Animated Graphics layered over an image / video
Web Banners – A form of web advertising that is embedded into a web page. They are used to attract a viewer to their website. A Web
Banner usually a mix of motion graphics and video
Video Format - 3 Main Formats HD, PAL, NTSC. HD is the highest resolution (720 or 1080 vertical lines in the image). PAL is the UK
Standard definition image (576 vertical lines). NTSC is the US Standard definition image (480 vertical lines). Now in the
digital age we now look at video format in terms of pixels (i.e. High definition 1080; 1920 x 1080 or 2,073,600 pixels)
Screen ratio – Standard TV ratio is 4:3; this means that for every 4 units wide it is 3 units high. It is likely that the screen ratio will be
Widescreen (16:9) in a cinematic sequence.
Resolution – The amount of detail in an image or signal, such as Standard TV Definition and High Definition. See Video Format.
Frame Rate - The number of video or film frames displayed each second (frames per second; fps). PAL frame (standard UK TV) is 25
fps, NTSC (standard US TV) is 30 fps, film is 24 fps. This means as NTSC updates more regularly there is less strobing
(jerkiness).
Compression – The use of Codecs (WMV, DivX) to reduce the file size of a video by a variety of methods. This sometimes means a loss in
image quality (a “lossy”). Codecs are found in Video Cameras, DVD players / recorders, Editing Packages, Video upload
sites)
