Tips for creating seamless videos with Start and End frames:
Create your Start Frame, then explore fresh perspectives and angles along the way with Nano Banana via our Inline Editor. Nano Banana also helps maintain character consistency across scenes, ensuring you achieve perfect end frames. (Alternatively use the End Frame as your jumping off point to create a suitable Start Frame)
Craft moody, cinematic shots with Lucid Realism, then bring them to life with Start–End Frame video transitions.
Longer videos may offer smoother but potentially slower transitions. Choosing a shorter duration may offer much faster but potentially less smoother transitions - consider subtler transitions for shorter videos.
Avoid having extremely different Start and End frames (such as different settings or extreme changes and transformations). Veo 3.1 is best used for clean actions within an specific scene or context. If fancier morphing or scene transitions are required, consider using Kling 2.1 Pro instead.
