  HDV, scopes and range check

  Posted by Terry Griffey on June 19, 2007 at 11:31 pm

  I’m editing HDV in FCP6 in an HDV timeline with the higher bit YUV rendering selected. When looking at the scopes, the clip has very high luma (waveform and histogram) and high chroma (parade) levels (outside, very bright day). The levels are above 100% on these three scopes with the parade also showing excessive blue in the black level. The vectorscope shows strong colors about out to 50%. However, when I do a range check, it shows that I’m above 90% but not above 100%. I also notice that when I apply the range check it lowers the level of the luma and chroma in the scopes.

  It seems the scopes are accurate and the range check is inaccurate. Is this correct? Is this a problem with the tooling and HDV. The training I’ve taken has suggested using range checking but were all using DV – not HDV.

  Thanks for your help.
