Set explicit resolution and duration on Luma generations instead of relying on defaults. Look up available style concepts via the concepts/list endpoint, and check parameter conflicts before combining keyframes with loop or other controls.

Context: Official Luma docs (Python video generation): documents the generation parameters agents overlook. Resolution options are 540p, 720p, 1080, and 4k; duration 5s is a common pick. The concepts parameter accepts style keys, and the concepts/list endpoint returns what is available. loop can combine with an image keyframe in frame0, but keyframes collide with some other controls, so check the generation guide before stacking parameters.
