Rendering ProRes 422(LT) from AE possible?

[Steve Roberts]

Try rendering just the alpha (set in the output module) of the keyed movie in AE. If you can’t render that to the ProRes codec, then render to Animation (alpha only). Open that in Quicktime and export to ProRes.

Then use that grayscale alpha movie as a track matte for your original footage in FCP.

However, if you’ve done spill suppression in Keylight (affected the talent), then you should also render the RGB to the Animation codec. That means make two Output Modules: one for RGB and one for Alpha, both to the Animation codec.

All,

I see this is a couple years old now so can someone just help me to ensure I am actually rendering ProRes 422(LT)?

This string tells me to select lossless, then quicktime, and under format, select ProRess 422LT. I do not see that option however.

The closest I see is: Uncompress YUV 8 bit 4:2:2

Is this the same thing and if not, can you help me?

Thanks.
Eric

Hi, I’ve tried your post and i have the same problem with Apple Prores. I do not find this option in the format options. I just had the choice first to choose f.e. quicktime and then under format option i miss this prores 422. Using lastest version of AE CC.
