To do it properly there needs to be a 'set format' action for the effect, which could simply
be piggy backed on the "set clip preferences" action. This would set the nominal
display format for the effect, which is distinct from the region of definition. eg: it is
NTSC format image, but we only has pixels defined for (10,10)->(100, 100).
Probably a worthwhile OFX extension for the other OFX host apps as well.
That would be nice (height,widht,par), probably useful for generators too
It does not have to be animatable (should be settable but same across a
clip duration)
It's listed in Feature List of API right now under Spatial Format, I am
all for bumping it up to OFX V1.4 candidates.

Another way as we don't really understand how to do that in Nuke either, what
we do right now for OFX plugins that need to produce an output larger then the
source is add an additional input as main input to plugin and connect to it a
constant node or something and make that the correct wanted size (use that
workaround to specify the output size). File a feature request :)

You need a crop node following your OFX plugin.
There, set the new output size and enable reformat.

The region of definition action should do it for you. It will change the
equivalent of the 'bbox' in Nuke. There is currently no way to change the
'format'.

I confess, I’m not familiar with ‘OFX’ format, but if you need to output
a double-wide image, I would start by setting the format.width in
_validate, and then simply provide the extra pixels in each engine call.
