1. A method, comprising: collecting a first set of processing information from a before-picture-lock version of an image data sequence that includes frames associated with each other temporally to form a motion picture with content that is changeable; storing the first set of processing information in a render data record; performing, using the render data record, initial conversion on the before-picture-lock version of the image data sequence to an enhanced image data sequence of the motion picture; subsequent to performing at least part of the initial conversion, detecting changes between the before-picture-lock version of the image data sequence and a final or substantially final version of the image data sequence by comparing the before-picture-lock version to the final or substantially final version, the final or substantially final version being generated subsequently to the before-picture-lock version being generated; and (A) in response to determining that the changes impact the render data record: (i) generating an updated render data record to include a second set of processing information collected from the final or substantially final version of the image data sequence; and (ii) completing conversion to the enhanced image data sequence of the motion picture using the updated render data record; or (B) in response to determining that the changes do not impact the render data record, completing conversion to the enhanced image data sequence of the motion picture using the render data record.
