A little walk down memory lane for anyone who's interested and wants to take a stab at this. I have what can only be described as a legacy system... It took many trials and tribulations to get it working and now I don't want to mess with it. I have a MacPro 2x2.66 running FCP 6 with a Matrox MXO. It all works great. My problem is, I don't have 24p playback with the MXO in my options and I don't think it's available even if I updated the software, which I'm very weary to do as this system is super finicky and like I said, it works flawlessly right now. I'm mostly working with 24p ProRess 422HQ coming via a Digital Bolex via LightPost. As a workaround, I've been editing in 24p then copying the sequence onto a 23.98 sequence so my Matrox MXO can play it on my second monitor for colour correction, then copying the filters back onto the original 24p sequence. For small things it's fine but for a larger sequence it's cumbersome. What is my best workaround? Is there a way to edit my 24p on a 23.98 timeline then export to 24p without messing with the frame order? Is there a way to trick the Matrox into playing 24p footage? Can anyone help? Thanks!
