Yes, the command you want is --chappend, which takes two images (say, containing N channels and M channels) and combines them into a new image with N+M channels.
You said you tried this... can you show us a command line that shows exactly what you tried? You may need a --chnames afterward to make the channel names make some kind of sense. Also, what file format are you using? Seeing the exact command you tried will probably answer all of the questions and then we'll know what to suggest. > On Aug 6, 2019, at 3:29 PM, Lydia Lam <[email protected]> wrote: > > Is there a way to merge AOVs with oiiotool?
