(Title, Credits, animated captions, stings, idents, interactive
menus, web banner)
Title Sequence
2. Brief description:
What do you see?
As there was no videos available of the title sequence by itself, I instead had to use
a video which started with the opening scene before going into the title sequence.
The title sequence fades in at 2:10 when the camera tracks up to the top of the
ocean from underneath after Marlin discovers that only one of his babies has
survived from the shark massacre, vowing to protect his son and calling him Nemo.
Behind the text the water is slightly wavy, then as the text (Walt Disney Pictures
present) is about to fade away it also begins to become wavy. This is a good
technique as it fits into the background and also fits in with the film as it is a story
that is set in the ocean. This happens again when another piece of text appears (a
Pixar Animations Studio film). The background changes, again in a wavy motion, as
the footage of the ocean habitat almost comes towards us. The film’s title/logo then
appears, also in the same fading wavy motion. The sequence then fades to black as
the film begins. All this happens with a very emotional piece of background
music, which sounds like a violin, which suits the scene and film itself to a tee.
3. Techniques used:
Animation, Visual Effects, Colour Rendering, Graphics, Movement
Obviously the film was made using CGI but as animation has progressed over the
years, and Finding Nemo is still a relatively new-ish film, it looks quite spectacular.
Although aware that the film is animated, and also predominantly aimed at
children, during the title sequence the animation is that good that it almost looks
real. The lighting of the scene is also used very well. With most of the fades and
transitions, a big bright light appears and is very eye catching. The colours are
perhaps the best use of a technique in the title sequence. As the film is set in the
ocean the animators would have had their work cut out in trying to recreate the
vast amount of colours that appear under the roof of the ocean water, but they do
it very well and it looks amazing. There is barely any movement other than the
tracks and the wavy fades. I think this is because the scene before the title
sequence was very frantic, panicky and quite scary (especially for an 8 year old –
which is how old I was when the film came out) so the very little movement of the
title sequence suggests that the film is trying to calm the audience and itself down a
little bit.
4. Advanced techniques:
Blur, Sharpen, Distortion, Rotation, Opacity
As mentioned before, the film attempts to calm itself down with the title sequence.
The use of the blur with the fading wavy motions is an example of this. The
background with the top of the ocean is also blurred. It looks like the ‘camera’ is
quite far down in the ocean, pointing up. Also mentioned before was the quality of
the animation, which the sharpen technique proves. We could go from a blurred
image to a really crisp one and it still looks visually pleasing.
5. Technical comments:
Video format, Screen ratio, Resolution, Frame rate, Compression
The video is played through YouTube;
Screen ratio: 16:9 (standard for widescreen)
Video format: 360p
The codec is Codec: H.264, which is also known as MEPG-4 AVC.
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.
