the material I worked with was shot on an SDX 900 and has a native frame size of 720×480, so I scaled down the y value to 75% (leaving the x value at 100%).
Also, with that codec, I think all of your material has to be captured in FCP in that codec before taking it out to AE. I have yet to try this workflow, but I’m curious about it and will use it in another week when a similar project comes through the door just like we are talking about now. Let me know how it works out for you.
I also did my titles after the AE render as the aspect ratio is now changed. SInce you have created them in an anamorphic setting, they might look funky squeezing them down to a non anamorphic setting, but that probably depends on how you set up your titles.
ANother advantage is that your whole program will be coming out of After Effects so your whole program will be effected with the gamma shift, which is good because your whole program will now be in the same color space so the 2vuy codec might not be necessary, but I’d like to know if this works anyway.
Hope all of this helps
