  The wider in mm, the film the higher the picture quality (resolution)

Page 4: The Tech Of Editing

  The frame is broken up into pixels (ppi), the more pixels there are, the better the quality.

Page 5: The Tech Of Editing

  There are different aspect ratios for different screen sizes varying the width and the height.

  Either PAL or NTSC   Lower quality than HD   Either 4:3 or 16:9 aspect ratio   Can be broadcast / shown in digital (Freesat)   DV PAL is an SD Format (Commonly used)

  Computers Encode video in lots of different formats.

  These are common consumer types.

Page 9: The Tech Of Editing

  Using the right format is important for maintaining the quality in a project.

  Some editing systems can’t accurately edit with certain formats due to problems caused by compression

Page 10: The Tech Of Editing

  Online editing uses the highest possible quality to edit.

  This takes a large amount of computing power and storage – when working with very large formats (2K/4K).

  Import the footage at a lower level of quality   Create an EDL (edit decision list) using the

software   Re-import the footage used in the edit at

high quality ready for final export.   Can speed up working.   Modern computers can deal with 1080p

footage online.   VFX operators still use offline/ online

processes.

  Film from a camera is linear, literally cutting up the film and gluing it together.

Page 13: The Tech Of Editing

  Digital Video editing is non linear

  You can reorder the footage and make changes at any time without any major problem

  You can go back and change an edit easily

  You can make fine adjustments

  You can create digital transitions and effects easily and quickly

  Tapes are not commonly used in Digital Video cameras to record information

  These have almost all been replaced by hard disk drives / memory cards

  The process of digitizing is faster and takes up less physical space.

  But the files are less secure and memory costs a lot of money.
