If you try to export a SheerVideo QuickTime movie to a 'v210' format such as Apple's "Uncompressed 10-bit 4:2:2" codec or Sheer Y'CbCr 10bv 4:2:2[:4] with QuickTime Player Pro and get the error message:

Couldn't export the movie "file.mov" because an unexpected QuickTime error occurred.

then you have encountered a critical bug in QuickTime which Apple fixed in QuickTime 7.0. When converting to or from the 'v210' (Y'CbCr 10bv 4:2:2) pixel format, earlier versions of QuickTime computed the row width incorrectly and allocated too little memory for the image. To avoid crashes, SheerVideo detects this condition and returns error code -2034, which means "Internal QuickTime Error."
