Mini Project- Digital Video Editing

3,171

Published on

The following resources come from the 2009/10 B.Sc in Media Technology and Digital Broadcast (course number 2ELE0073) from the University of Hertfordshire. All the mini projects are designed as level two modules of the undergraduate programmes.

The objectives of this module are to demonstrate within a digital broadcast environment:
• an understanding of technical requirements for digital video production process.
• an awareness of technical constraints for content creation and distribution.
• the creation of a video sequences with extra effects added.

This project entails the creation, editing, and encoding of a video sequence with the intention of distribution over a particular digital broadcast platform (e.g. DVB-T or ipTV). This project provides an awareness of current video standards for television and also introduces the use of contemporary digital video authoring tools and processes.

  3. 3. Project Summary <ul><li>This project entails the creation , editing , and encoding of a digital video sequence with the intention of a particular application: </li></ul><ul><ul><li>Distribution over a particular digital broadcast platform (e.g. DVB-T or ipTV). </li></ul></ul><ul><ul><li>Storage on a particular digital media </li></ul></ul>
  4. 4. Tasks to complete <ul><li>Preproduction </li></ul><ul><ul><li>Planning the recording </li></ul></ul><ul><li>Production </li></ul><ul><ul><li>Recording (and importing from tape) </li></ul></ul><ul><ul><li>Selecting </li></ul></ul><ul><ul><li>Assembling </li></ul></ul><ul><ul><li>Editing </li></ul></ul><ul><li>Post-production (Encoding) </li></ul><ul><ul><li>with the intention of distribution over a particular transmission media </li></ul></ul><ul><ul><li>or with the intention of storage on a particular storage media </li></ul></ul>
  5. 5. Adobe® Premiere Pro CS3 ® - Presets <ul><li>DV-24p – 24p DV cameras sometimes used for film that has been shot at the film-standard 24 fps and transferred to DV. </li></ul><ul><li>DV-NTSC – TV format for North and Sourth America and Japan. </li></ul><ul><li>DV-PAL – TV format for mast of Western Europe and Australia. </li></ul><ul><li>HDV </li></ul><ul><li>Mobile & Device – Video from mobile devices and other low-bandwidth video. </li></ul><ul><ul><li>Virgin mobile’s mobile TV service @59 kbps </li></ul></ul><ul><ul><li>MPEG2 for DVB @ 3-15Mbps </li></ul></ul>
  6. 6. How to decide the technical parameters when create a new project in Adobe® Premiere Pro CS3 ® ? <ul><li>Investigate the project specification and identify the required video format </li></ul><ul><li>Use the identified format for your project </li></ul><ul><li>If new contents are required, make sure the same format is used when capturing the new contents. </li></ul><ul><li>When existing contents are to be used, try to use contents with the same format. </li></ul><ul><ul><li>Chroma keying </li></ul></ul>
