When using Final Cut Pro 5.x to open clips previously captured with DeckLink 4.x or older drivers, a gamma shift may be seen in the video in some cases. A filter can be used to adjust the gamma to the expected level.
Blackmagic uncompressed 8 and 10-bit codecs were originally introduced before Final Cut Pro provided its own uncompressed codecs.
Final Cut Pro 5.x provides uncompressed 4:2:2 codecs for both SD and HD video. Accordingly there is no longer a need for the Blackmagic codecs and they are no longer included with the DeckLink and Multibridge drivers.
A side effect of the switch from Blackmagic to Apple uncompressed codecs is that a gamma shift may be observed if media that was rendered with the Blackmagic uncompressed 8 or 10-bit codecs is opened in to Final Cut Pro 5.x. This is due to differences in treatment of gamma levels between the codecs.
Download and install the Blackmagic Gamma filter for Final Cut Pro. Apply this gamma filter to your legacy clips and they will now appear correctly in Final Cut Pro 5.x. You will need to render any video to which the Blackmagic Gamma filter is applied for smooth playback or output to tape.
