After you import a script or create a custom list, you can use the Shot Lists & Storyboard feature to visualize your project scene by scene, shot by shot. Are you trying to crop your pictures? If your images don't look right, try adjusting the image Aspect Ratio.
Step 1 — Navigate to Layout
On the Shot List page, click on Layout to view the available aspect ratios.
Step 2 — Adjust Aspect Ratio
After selecting a new aspect ratio, you'll see the changes update in real-time.
