Hmmm… Well first off The Gamma Shift of your original file (checked on both a PC and Mac) is due to the difference in Gamma level outputs. Most PC’s show a Gamma level of somewhere between 2.2 and 2.4. A Mac’s default Gamma is 1.8 I believe. Check out this link for furthur reading:

How do you need to deliver your project? If your delivering for the web (where most people view videos on pc) then I would change your mac gamma settings in the mac OS ColorSync control to the value of a PC so that you can view your file (on your mac desktop) as most would see it. Heres a link on how to do it:

Alternatively you could add a gamma correction filter from fcp and adjust it to match the output of your PC (just to see the file as you were seeing it on a PC).

I would strongly suggest checking your file on a CRT as the Gamma output would be very similar to a PC. Its also worth checking your gamma settings on your monitor and video card (if they are adjustable).

As for the Gamma jump between the two files with different codecs in the same timeline I can only assume that the DNxHD codec has a gamma value suitable for PC’s and not macs.
Hope this helps.

Hi Stuart, what kind of broadcast monitor are you using? A CRT? And are you using the one monitor to compare? Ie. Are you pumping out your Avid output to the same monitor of your FCP output and doing the compare there?

Hi Emmet,
Are you viewing the roller on a CRT? If so it sounds like your type is ‘flickering’ between two scan line as it rolls upwards. The best way to get around this is to blur the text by 1 pixel (Vertically) so that the type blurs across the scan lines creating a smooth roll. Its also a good idea to set your type to continuously rasterize so that the type is as sharp as possible. I have created many rollers for broadcast in this manner and they always pass with flying colours!

Now unfortunately Borris doesn’t have these features but After Effects does. After Effects will also allow you to implement your graphical elements and parent them to your type. Hope this helps and good luck with your project.
