ConvertFrame returns E_NOTIMPL

I am trying to use the built-in ::ConvertFrame to convert from bmdFormat10BitYUV to bmdFormat10BitRGB (other RGB formats would be ok). I get a 'not implemented' return code. I have the Intensity Pro 4K card.
Should this work? I just want to know if the conversion *should* be supported before spending any more time trying to find a mistake of mine.

I've solved my problem: I was creating a large buffer to convert to, large enough to hold the maximum size input our application supports. If I make the convert-to buffer the same size as the convert-from frame, the conversion succeeds.

Hi Mark,
Glad to hear you solved the issue - I can confirm that the behaviour you observe is expected, as IDeckLinkVideoConversion[1] currently supports pixel format conversion only, so the source and destination video frame objects must have matching dimensions.
Cheers,
