Broadcast Video Standards

NTSC (National Television Standards Committee)

  • –  525 lines/60Hz
  • –  This standard is used primarily in North America, Taiwan, South Korea, Japan.

    PAL (Phase Alternate Line)

  • –  625 lines/50Hz
  • –  This standard is used primarily in Europe, Asia, and Southern Africa.

    SECAM (Systeme Electronique Couleur Avec Memoire)

  • –  625 lines/50Hz
  • –  This standard is used primarily in France, parts of Middle East, and Russia. 

Aspect Ratio

The aspect ratio of a frame describes the ratio of its width to its height in the dimensions of a frame

For example, the frame aspect ratio of NTSC or PAL video is 4:3, whereas DVD, HDTV, and motion-picture frame sizes use the more elongated aspect ratio of 16:9 

 

Video Effects

A video effect determines how a video clip, picture, or title displays in your project and final movie. Video effects let you add special effects to your movie.

A video effect is applied for the entire duration that the video clip, picture, or title displays in your movie. You can add any of the video effects that appear in the Video Effects folder in the Collections pane. 

Titles and credits

Titles and credits let you enhance your movie by adding text-based information to your movie.

You can add whatever text you want, but you may want to include information such as the title of your movie, your name, the date, and so forth.

You can change the appearance of the title or credit, in addition to changing the title animation, which determines how your title or credit displays in your movie. 

Working with Audio

Windows Movie Maker lets you work with audio in a variety of ways:

Narrate the timeline. Add an audio narration to narrate the video clips or pictures that appear on the Video track of the timeline. Your audio narration is automatically synchronized with the video, so the narration describes the action or event in your movie as it plays back.

Adjust audio levels. Adjust the audio levels so you can determine the audio balance and playback when you have audio that appears on the Audio/Music tracks on the timeline.

Add audio effects. Add different audio effects such as a fade in, fade out, or mute.

Adjust the volume of audio clips. Adjust the volume of audio for audio-only clips or the audio portion of a video clip. This lets you adjust the volume of the audio for clips so that it can be clearly heard or not heard, depending the volume level you specify for the audio clip.
