How to add AI effects to an existing video

Keep enough footage before and after the main action to show what is happening. A clear subject, continuous movement, and limited obstruction make it easier to understand the relationship between people, objects, and the setting.

A useful direction explains who or what should change, when the effect should begin, and what the viewer should see. Instead of only asking for “something dreamy,” try: “After the subject turns, soften the background light and gather small particles along the direction of the movement.”

Add the overall feeling you want the video to carry—restrained, energetic, playful, mysterious, or cinematic. A single coherent direction is more useful than a long list of conflicting style words.

The job moves through video understanding, effect generation, and final rendering. Closing the page does not cancel a submitted job. Return to the workspace to see the latest status in the production queue.

When the result is ready, play both versions and check the main action, subject visibility, effect timing, orientation, and audio. Download the finished video when it is right. For a different creative direction, revise the description and create another version.
