Brief description: Two big gold cirlcles are flying around each other and then fly around the World Cup trophy. I
What do you see? think the gold circles represent the world orbiting around the sun and stars and the World Cup
trophy represents the sun and the most important thing in life which people who play football
will think the World Cup is the most important trophy in the World.
Techniques used: They have used Animation with the circles. They have used colour rendering with the circles
Animation, Visual Effects, Colour Rendering, being the same colour as the trophy. They also used graphics to create the circles. They also
Graphics, Movement used movement on the circles.
Advanced techniques: The main advanced technique they use is sharpen to make the animation and the logo a better
Blur, Sharpen, Distortion, Rotation, Opacity quality and resolution.

Technical comments: Codec: H.264
Video Format, Screen Ratio, Resolution,
Frame rate, Compression A codec is the format in which your video will be encoded. Different codecs have different
features and varying quality. For best results, we recommend using H.264 (sometimes
referred to as MP4).
This H.264 codec implements the H.264 (baseline) video compression standard. It provides
high-quality video encoding and decoding for real-time video transmission applications. This
H.264 supports a wide range of data rates. The codec preserves good picture quality both at
high and low bit rates.
This H.264 is also deeply optimized for real-time image compression on PC and ARM
platforms and can be ported to other platforms. This H.264 provides real-time encoding of
4CIF on a 2 GHz Pentium 4 CPU.
H.264 / MPEG-4 AVC
Overview
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.
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.
Frame rate: 24, 25, or 30 FPS
If you know at which frame rate you shot, it is best to encode at that same frame rate.
However, if it exceeds 30 FPS (frames per second), you should encode your video at half
that frame rate. For example, if you shot 60 FPS, you should encode at 30 FPS. If you're
uncertain what frame rate you shot at, set it to either "Current" or 30 FPS. If there is an
option for keyframes, use the same value you used for frame rate.
Resolution: 640x480 (SD), 1280x720 (HD)
Choose 640×480 for 4:3 SD video, 640×360 for 16:9 SD video, and 1280×720 or
1920×1080 for HD. If you have the option to control the pixel aspect ratio (not the display
aspect ratio), make sure it's set to "1:1" or "1.00," sometimes referred to as "square

Glossary
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
