Video Color Standard


In order for Synchromy to losslessly convert between RGB and Y'CbCr color spaces, SheerVideo lets you specify the video color standard of the Y'CbCr target for Sheer Y'CbCr[A] codecs, and of the Y'CbCr source for Sheer RGB[A] codecs. Click on one of the following radio buttons in the Video Source Default section of the Sheer Settings dialog box:

  • NTSC NTSC, for composite NTSC (SMPTE 170-M-1994), digital 525 (SMPTE 125-M-1995, SMPTE 267-M-1995, SMPTE 259-M-1997), or 720x483 progressive 16:9 (SMPTE 293-M-1996)
    This is the default value.
  • PAL PAL, for composite PAL or SECAM (ITU-R BT.470-4), or for digital 625 (ITU-R BT.656-3).
  • HD HD, for all current HD formats (ITU-R BT.709-2), including 1920x1080 HDTV (SMPTE 274-M-1995) and 1280x720 HDTV (SMPTE 296-M-1997).
  • HD 1035 HD 1035, for 1920x1035 HDTV (SMPTE 240-M-1995, SMPTE 260-M-1992) as well as the obsolete interim color implementation of 1920x1080 HDTV (SMPTE 274-M-1995).
