  2. VideoEditing

  3. Capturing and Importing Source Clips Source material exists in two main forms: • Digitalmedia is stored in a file format that a computer can read and process directly. All digital-video (DV) camcorders and decks record video and audio in digital format. • Analogmedia must be digitized, or converted to digital form, before a computer can store and process it.

  4. Understanding offline and online editing • Online editing is the practice of doing all editing (including the rough cut) on the same clips that will be used to product the final cut. • In offline editing, you edit video using low-quality clips and produce the final version using high-quality clips on a high-end system.

  5. Connecting the analog video source

  6. Connecting the analog video source

  7. Connecting the DV video sourceIEEE1394 (FireWire/i.Link).

  8. Connecting the DV video sourceIEEE1394 (FireWire/i.Link).

  9. Video Resolution

  10. NTSC & PAL

  11. Aspect Ratio Pixel aspect ratiospecifies the ratio of width to height of one pixel in an image.

  12. Aspect Ratio

  13. Setting pixel aspect ratio • Square Pixels Uses a 1.0 pixel (640 x 480 or 648 x 486) • D1/DV NTSC Uses a 0.9 pixel (720 x 480 or 720 x 486) • D1/DV NTSC Widescreen Uses a 1.2 pixel (720 x 480 or 720 x 486) result is a 16:9 frame • D1/DV PAL Uses a 1.0666 pixel(720 x 576) result is a 4:3 frame • D1/DV PAL Widescreen Uses a 1.4222 pixel (720 x 576) result is a 16:9 frame • D4/D16 Standard Uses a 0.9481481 pixel (1440 x 1024 or 2880 x 2048) result is a 4:3 frame

  14. Transitions • The visual change from one clip to another is called a transition.

  15. Image Mask

  16. Gradient Wipe transition

  17. Creating Titles • The safe zones indicated by Premiere represent only NTSC video and are only guidelines for other video standards such as PAL or SECAM.

  18. Alpha Channel key • An alpha channelis a fourth channel in an RGB image that defines what parts of the image are transparent or semitransparent.

  19. Garbage mattes • Sometimes the subject of a scene is properly keyed except for undesired objects. Use a garbage matteto mask out those objects. You can then place the keyed subject in another scene for simple effects.

  20. Animating a Clip • Animate a clip by creating a motion path in the Motion Settings dialog box. • rotation, zooming, delays, and distortion

  21. Exporting video from Premiere File types available for export • Video formats Microsoft AVI, Animated GIF, QuickTime, MPEG, RealMedia, Windows Media, DV • Audio-only formats AIFF, MP3, and Windows Audio Waveform • Still-image and sequence formats Filmstrip, FLC/FLI (Windows only), GIF sequence, PICT and PICT sequence (Mac OS only), Targa and Targa sequence, TIFF and TIFF sequence, Windows Bitmap and Windows Bitmap sequence
