Is there a way to fetch the result of a COP network live into TOPs without having to render out?

Trying to make a TOP network to read in EXRs, rotate them in COPs, and then read them back into TOPs to convert to MP4 with FFMPEG.

Closest I've got is using 'ROP Composite Output' but I can't get it to not render the result, and just output it as work items.

You have to write them out as images again so that your ffmpeg process can access them

Shame, but thanks, Tomas. I thought it might be a limitation.
Will write an RFE for it.
