# Image-to-video: choosing a good first frame

When you animate a still image, the first frame carries most of the weight. A well composed opening frame gives the model a clear subject, a believable light direction and room for movement. A cluttered one produces jitter and strange morphing.

Look for images with a clear foreground subject and an uncluttered background. Leave space in the direction the subject will move; a character about to walk right needs empty room on the right. Avoid hands holding small objects in the frame if the motion is subtle, because fingers are where artefacts tend to appear first.

Describe only the motion in your prompt. The image already says what the scene looks like, so repeating the details can conflict with it. Something like “slow push-in, hair moves in a light breeze, background traffic blurs” is plenty.

If you want to try the technique, this AI video tool lets you start from a frame and add references. Keep the first test to four or five seconds and judge only whether the motion feels natural.
