I submitted a bug to apple. Here’s a link to the image which I added to my report. The point is- the FCP ‘Broadcast Safe’ filter does not seem to perform as advertised.

BUG DESCRIPTION SENT TO APPLE:
Final cut Pro (v5.0.3 for sure – perhaps others) does not provide video clamping to the 100% mark – actually appears to be rather ineffective regardless of threshold/settings. See the enclosed image for a comparison of a frame before and after the filter is applied.
Additionally, it appears the behavior of the filter is not to simply squash the excessively bright pixels to a legal level, but rather it compresses values of all of the pixels near what would be the ‘whites’ range of the color corrector down towards black – which effectively reduces the dynamic range of the image in the brighter areas – instead of simply removing the influence of pixels which are too bright.

Anybody else have any thoughts about how best to make use of ‘Broadcast Safe’?
