3D storyboarding lets you explore the same scene from different camera positions. Simple characters and props are enough to communicate where things are, which way they face and what the camera should see. In Reelpen, that layout can also become a moving reference.
Block the important action
Write down what the viewer needs to understand in one shot. Add only the characters and objects needed for that action. Place them in the scene and give them clear names so you can select them easily. Add ground or background objects when they help explain distance, scale or the setting.
Compare camera angles in one scene
Use the Camera card in Add to create another camera. Select each camera in the scene list and compare its view of the same arrangement. A wider shot can explain the space; a closer angle can direct attention to a subject. Change the camera position and lens while watching its preview.
Check movement and look direction
A still layout may hide a problem that appears during movement. Give the character a path with Move and set a look target where needed. Play the scene and check that the action remains readable throughout the shot, including pauses and the final position.
Export frames that explain the shot
Choose useful moments at the start, during the action and at the end. Export the available PNG frames or a short reference video. Save an editable JSON copy as well if you want to revisit the arrangement later. A reference frame communicates composition; video also communicates timing and motion.
Separate shot planning from the final look
Use the same scene to try an alternative camera or arrangement before another generation. Supply supported references to your chosen AI video tool and use its prompt to describe the intended style. Keep notes on what the model preserved and what changed. Reelpen's 3D scene remains editable, so you can refine the next reference without rebuilding the shot from scratch.
