MORE about MATRIX

Synergistic Storytelling

THE MATRIX is a series of comics from cult writers and artists, such as Bill Sienkiwicz (Elektra: Assasin, 1986-87), Neil Gaiman (The Sandman, 1989-96), Dave Gibbons (Watchmen, 1986-87), Paul Chadwick (Concrete, 1987-98), Peter Bagge (Hate, 1990-92). THE MATRIX is also two game - ENTER THE MATRIX produced by David Perry's Shiny Entertainment, and a massively multiplayer gamer set in the world of THE MATRIX, scripted in part by Paul Chadwick.

The Wachowskis wanted to wind the story of THE MATRIX across all of these media and have it all add up to one compelling whole.

One Example: In the Matrix Reloaded, Niobe appears unexpectedly in the freeway chase just in time to rescue Morpheus and Trinity, but for people who play the game, getting Niobe to the rendezvous point is the key mission. We reencounter Niobe at the start of THE MATRIX REVOLUTIONS where she was left off at the climax of the game ENTER THE MATRIX.

By the standards of classical Hollywood storytelling, these gaps (such as the failure to explain where Niobe came from) or excesses in the film confuse the spectator. The old Hollywood system depended on redundancy to ensure that viewers could follow the plot all all times, even if they were distracted or went out to the lobby for a popcorn refill during a crucial scene. The new Hollywood demands that we keep our eyes on the road all times, and that we do research before we arrive at the theater.

A little too much asked from a film goer who is not so handy with other media's. Targeting thus only to a niche audiences, this is where the filmmakers did a little wrong as the excitement that THE MATRIX created didn't get reflected that much with the sequels, but it can still a glorified failure. Why? Read on...

Understanding HD - Scan Lines

What are Scan Lines?



What is ‘p’ and ‘i’ we often see when frame rates are mentioned like 25p or 60i, well, the answer lies with Scan Lines.

SCAN LINES:

The video you see is created by a series of horizontal lines as they are scanned across the screen starting the top. When is image creations happen at one go all the way to the bottom, it’s called Progressive
Scanning (p).

With other types of video, the scan lines first draw the even-numbered lines until they get to the bottom and then again resume from top, this time around with the odd-numbered lines, it’s called Interlaced scanning (i).


Each time they pass through either the odd or even numbered lines is called a Field. So, Interlaced scanning has two fields. The order in which the fields are drawn can change, depending on how the video is recorded. So, a 25 fps interlaced video is updated 50 times, 2 frames each. Remember? Hence the term – 50 i
25 Frames per second = 50 Interlaced Fields per second



Which one is better?

Since interlaced video uses two fields, so when shooting anything in motion, interlaced fares better. But, with all household electronics or laptop or LCD monitors in the market – Progressive is definitely the way to go. Moreover, when you are converting your video in terms of frame rates and resizing, for Progressive as the conversion software doesn’t have to worry about fields. Progressive have no fields.

Watch this video tutorial explaining about Interlaced Vs Progressive – it will become clearer.

Understanding HD - Frame Rates


WHAT IS HD AFTERALL?


The most basic definition to begin with is: all digital formats with a resolution greater than standard definition (SD) video are considered HD. The definition gets more complicated as we consider HD as a set of digital video formats rather than just one.

When digital filmmakers talk about shooting in HD, they talk about following three subsets: 720, 1080 and digital cinema. Scanning lines, Frames always is a part of the discussion when we try to explain the three subsets as mentioned above, so let’s understand them first:

 FRAME

The Video track is actually made up of series of still images, and when they are played in sequence, they appear to be moving. Frames of video are similar to frames of a film, just that you can’t hold them in your hand and point towards a light and see them. It’s not cellulose after all, but it works in the same principle. Instead, you need a computer to decode the electronic information that constitutes each frame and display it on a monitor.

The number of still images, or frames per second is called as FRAME RATE. The standard frame rate before the advent of sound in film used to be 14 – 18 frames per second. In the mid- to late-1920s, the frame rate for silent films increased to about 20 to 26 FPS. (Wikipedia). This change happened because it needed to synched with sound. So, soon films were running at 24 frames per second (fps). So, when you watch any of the silent films now, they appear to run faster as more frames are running per second than what was originally shot.

When it comes to HD, there are different frame rates associated with it. It needed to be compatible with American Analog  broadcast video, European analog broadcast video, so, here the subsets of three potential sources of HD frame rates:

  1. 24p and 23.976p. Frame rates based on Film. You will probably shoot in 24p, if you eventually want your footage shot in Video to be transferred to Film eventually. To know more why or why not you should go for 24 frames per second, see this tutorial by Larry Jordan: http://youtu.be/FO2dD4Z4oYI
  2. 29.97p, 30p, 59.94i, 60i, 59.94p, and 60p. Frame rates based on American television
  3. 25p and 50i. Frame rates based on European television.


What is ‘p’ and ‘i’ means, we will explore in the next section on scan lines, in my next post.
