The document discusses an interactive menu for a film called "Greenstreet" that will be used on a DVD. The menu features faded film clips in the background with a red title on a green background to draw attention. Advanced techniques like blur, distortion and opacity are used on the clips. The menu is formatted for DVD playback with a 16:9 aspect ratio, 25 frames per second, and a resolution of 720x480 pixels using MPEG-2 video compression.

Brief description: Faded clips of the film can give the audience a sense of excitement as it shows different
What do you see? parts of the film which seem to be more interesting for the audience to engage with.
In the background selected scenes
A red title on a green pitch makes it stand out more and hopefully the title of the film
will be more remembered as red can be seen as a significant colour to the human eye.
Writing placed slanted on the grass
Clips of people waiting about as is something is about to happen which can create an
atmosphere which people will relate to and get involved with
Techniques used: Colour rendering – green faded images within background
Animation, Visual Effects, Colour Rendering, The only movement we see is the movement from the clips behind the main menu
Graphics, Movement The visual effects give off a sense of hostility. Using certain clips creates an
atmosphere/tension before the film has even started.
Advanced techniques: There is a slight distortion, blur and opacity within the clips selected
Blur, Sharpen, Distortion, Rotation, Opacity There is no sign of rotation
Sharpen appears to be used on only the grass and text
Technical comments: H.264 / MPEG-4 AVC
Video Format, Screen Ratio, Resolution,
Frame rate, Compression 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. 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.
Screen ratio 16:9 – This has been chosen because is it usually the screen ratio for most DVD’s.
However if it was being viewed on a computer as such, the screen would then be a ratio 4:3.
Frame Rate – From the research, this is what I found about frame rate :
To record moving pictures, DVD-Video uses either MPEG-2 compression at up to
9.8 Mbit/s (9,800 kbit/s) or MPEG-1 compression at up to 1.856 Mbit/s (1,856 kbit/s).

The following formats are allowed for MPEG-2 video :
At 25 frames per second, interlaced (commonly used in regions with 50 Hz image
scanning frequency):

720 × 576 pixels (same resolution as D-1)
704 × 576 pixels
352 × 576 pixels (same as the China Video Disc standard)
352 x 288 pixels
At 29.97 frames per second, interlaced (commonly used in regions with 60 Hz
image scanning frequency):
720 × 480 pixels (same resolution as D-1)
704 × 480 pixels
352 × 480 pixels (same as the China Video Disc standard)
352 x 240 pixels
The following formats are allowed for MPEG-1 video:
352 × 288 pixels at 25 frame/s, progressive (Same as
the VCD Standard)
352 × 240 pixels at 29.97 frame/s, progressive (Same as
the VCD Standard)
Video with 4:3 frame aspect ratio is supported in all video
modes. Widescreen video is supported only in full D1 resolutions.
This shows each of the FPS.
Resolution – From looking at the research I have done, I cannot be exactly certain, as the
resolution was 720 x 480 on nearly every page I looked. The image itself didn’t seem to be in
HD.
Video Format – From the research, the DVD-Video is a consumer video format which is used to
store digital video on a disc. The video format is encoded in MPEG-2 format.

Looking into the video format more, MPEG-2 is the main video format for DVD-Video,
however, MPEG-4 seems to be the best fit in terms of the generation today.
MPEG-2
Overview
MPEG-2 is a standard for broadcast-quality digitally encoded video. It offers outstanding
image quality and resolution. MPEG-2 is the primary video standard for DVD-Video
Pros
Excellent image quality
Cons
Very few people are currently capable of viewing MPEG-2
Licensing fees (typically US $0.04 - $0.40 per unit) are required to distribute MPEG-
2 video.
