The Technology of Editing

Film vs. Digital• Arguments about what gives better picture quality goes on, its still

hard to decide the winner in the battle.• Whilst being more expensive digital cameras can match up with

the quality of film cameras, they are also lighter and more appealing so in my opinion digital is the clear winner out of the two.

• IMAX film is agreed and known to most people to be the best picture quality around, with three projectors to give the perfect picture quality IMAX is the overall winner.

Film Size• Film over the years has came up with mind blowing quality, effects

and film types over the years.• Film picture quality increases as the film widens in millimeters,

this smoothen the resolution.

Digital Resolution• Pixels are what give screens quality, the more pixels the higher

the quality.• Having more pixels means the screen has to be widened , this is

why as the screen widens the picture quality increases.• In digital imaging a pixel, is a physical point in a raster image, or

the smallest addressable element in a display devise; so it is the smallest controllable element of a picture represented on the screen.

Aspect Ratio

The aspect ratio of an image describes the proportional relationship between its width and its height.

It is commonly expressed as two numbers separated by a colon, as in 16:9. For an X:Y aspect ratio, no matter how big or small the image is, if the width is divided into X units of equal length and the height is measured using this same length unit, the height will be measured to be Y units.

Standard Definition vs. High Definition

• Standard and high definition is either PAL (Phase Alternating Line) or NTSC ( National Technical System).

• Their picture qualities are lower than HD (High Definition).• The aspect ratio is usually either 4:3 or 16:9.• They can both be broadcasted.• They are shown in digital.• Digital video PAL is a standard definition format, we use this

format a lot.

Capture Formats

Formats

• The computer ENCODE video has loads of different formats. These are the most common consumer types.

The Right Digital Format• To maintain quality it is important to use the right formatting

system.• Some editing systems can’t accurately edit with certain formats

due to problems caused by compression.

Online vs. Offline• Online editing uses the highest possible quality to edit, whereas

offlines quality is not as good but the edit is faster.• The takes large amount of computer power and storage – when

working with very large formats (2K/4K) not a good idea.

Offline Editing• Offline editing makes the imported footages level of quality

decrease.• Offline editing allows you to create an EDL (Edit Decision List)

using its software.• Used to be used more than online editing.• Very helpful for those who don’t have internet.• Re-import the footage used in the edit at high quality ready for

final export.• Using offline editing can speed up working. • Modern computers can deal with 1080p footage online. • VFX (Visual Effects) operators still use offline and/or online

processes.

Linear vs. Non Linear• Footage take from a camera is linear.• Digital video footage is non linear.

Non Linear• Digital video editing is non linear.• It makes digital transitions and effects easier and faster to

perform.• Digital adjustments become finer.• Going back and changing edits how now become a lot easier to

do.

• Using non linear editing makes it easier to change footage when

editing without making any major mistakes..

Tapes vs. Hard Discs• Tapes are being replaced with hard disks and memory cards.• Its rare for a video tape to be used in a digital camera.• Memory cards and hard drives are a lot faster than tapes. • The files that hold information are more secure.
