The Technology of Editing

  1. 1. 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.
  2. 2. 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.
  3. 3. 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.
  4. 4. 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 acolon, as in 16:9. For an X:Y aspect ratio, no matter howbig or small the image is, if the width is divided into X unitsof equal length and the height is measured using this samelength unit, the height will be measured to be Y units.
  5. 5. 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.
  6. 6. Capture Formats
  7. 7. Formats • The computer ENCODE video has loads of different formats. These are the most common consumer types.
  8. 8. 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.
  9. 9. 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.
  10. 10. 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.
  11. 11. Linear vs. Non Linear• Footage take from a camera is linear.• Digital video footage is non linear.
  12. 12. 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 ..
  13. 13. 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.
