Five AI video generation tools with first and last frames to solve the problem of video characters in one shot and multi-subject/painting style consistency

opening and closing framesintroduce

Keyframes is a term used in the field of video production and animation to refer to frames in an animation sequence that define the state of an object at a specific point in time.

The first frame (Keyframe) usually refers to the keyframe at the beginning of the animation, while the end frame (Endframe) is the keyframe at the end of the animation. In video production, the first and last frames are used to determine the start and end states of the action, as well as the transition between them.

In AI video generation software, the first and last frame feature allows users to specify the start and end frames of the video, usually by uploading two images.

The AI software automatically generates intermediate frames based on these two images and possible additional instructions (e.g., text cues, stylistic requirements, etc.) to create a video that smoothly transitions from the first frame to the last.

This technique can be used to create a variety of visual effects, such as deformation of objects, scene transitions, and character movement.

3. efficiency: Users do not need to create each frame manually, saving time and resources, especially in complex animations.
4. inventive step: The first and last frames feature opens up new creative spaces for users to quickly prototype and test creative concepts.
