Is it true that shots must be conformed before VFX can be applied?

The assertion that shots must be conformed before visual effects (VFX) can be applied is accurate. Conforming is the process of matching the edited version of the footage with the original camera files to ensure that every cut and transition aligns perfectly. This step is crucial because VFX work is typically performed based on the precise timing and framing established in the edit. If the VFX artists are working from a version that is not conformed, they risk working with incorrect timing, cuts, or even resolutions, leading to potential misalignment when the VFX are integrated back into the final cut. Therefore, conforming ensures that the VFX elements will seamlessly blend with the edited piece when complete, thereby maintaining the integrity of the visual storytelling.
