Yeah I tried both methods, but still no luck. There’s no difference in how the clips are encoded between the two, just a script in the program that tosses the files into your project after rewrapping the mp4 into mov. For this issue I’m having, I’m betting on either something wrong with Adobe’s playback engine or a configuration error with the Kona3 or the Nvidia 4800 since this is isolated to this machine. Workaround to prores for now, but still troubleshooting.
I was running into this problem when editing in ProRes 422HQ sequences, then I found a solution that allows you to keep your reds wherever you want them from AE to FCP. All I did was change my render output to Animation in AE and then export my sequence from FCP as Animation.
If you wanna do a test just duplicate your FCP sequence and change your sequence settings to Animation as well and your aliased red text should be smoothed out.
