Apple QuickTime Player

The simplest way to decide which Sheer codec to use is to just use the generic Sheer codec, which decides for you on the basis of the format of the data it receives from QuickTime. However, sometimes QuickTime will convert your video from its native format to a different format before handing it to Sheer. Many such format conversions are impossible to accomplish with perfect fidelity, so QuickTime may degrade the image in the process. Unfortunately, SheerVideo has no way of finding out what the original video format was. To reduce the chance that QuickTime covertly converts the format, you can find out what your video format is, and manually choose the appropriate specific Sheer codec. To find out what video format your movie has,

  • Window > Show Movie Properties… Select Window > Show Movie Properties… in QuickTime Player's menu bar to bring up the Movie Properties window for the movie.
  • Properties Window

  • Video Track Select the Video Track in the track list in the Movie Properties window.
  • Format Sheer Look at the Format column to discover the format of the video tracks, and choose the appropriate Sheer codec according to this table:

QuickTime Player 7.0 no longer provides a mechanism for determining whether an individual video track contains an alpha channel. However, to find out whether your movie as a whole contains an alpha channel,

  • Window > Show Movie Info… Select Window > Show Movie Info… in QuickTime Player's menu bar to bring up the Movie Info palette.
  • Movie Info

  • Look at the Format field.

    • Format: Millions If the Format field ends with Millions (or anything less), the movie does not have an alpha channel.
    • Format: Millions+ If the Format field ends with Millions+, the movie does have an alpha channel.
