So if you get a sequence back from the render farm that looked fine on your screen, but all the roto is wrong or missing in the result, set those mask dimensions yourself. That usually only happens in non-interactive sessions. It should therefore be the default format of the project, which might differ from the footage, leading to an incorrect calculation of the transformation.Īnother time the auto-sizing might fail is if you're rendering with Simultaneous Branching turned on, in which case sometimes the mask will be render before the tool downstream has finished determining its own size, and it will take the default dimensions. In this case, the Rectangle is plugged into the main Input of the Planar Transform, so the size of the Planar Transform's raster is determined by the Rectangle itself. It can only do that when the mask (or chain of masks) is plugged directly into an EffectMask input of a tool that will otherwise report its own size.
To expand on that a little, for the benefit of those who aren't used to some of Fusion's foibles: Sander de Regt wrote:(it should take its size from the image its masking, but it doesn't always do that).
