HI All,

I have an empty Houdini scene with no OBJ nodes or cameras. I have an image that is moving in the COP network.

How do I actually render my moving image from the COP network into a final image sequence?

When I add nodes to the OUT context, they all turn RED and error out…?

Even trying to render a single image from the OUT network does not work.

You can render it from both COP context and OUT context.
In OUT context use “Composite” rop and in COP context use “ROP File Output” cop.

Thank you, the file output from the COP network works for me.

Just another question…

Can Houdini render to a MOVIE format? All I see are image formats in the file output node.

nope.
and you really don't want to do that…
whatever OS you're using there are 100's of free and commercial apps that will take an image sequence and render them to a video format with lost of control over bit rate, codec etc.

If you open or render to MPlay, then File menu, Export/Quicktime Movie Exporter.. gives some options

Ah, I'll have to try that Marty.
