Treat every clip as one shot
By now you have several clips: product shots, lifestyle scenes, the surfer with the drink. Instead of treating each generation as a finished video, treat it as one shot of a future edit.
Pick the shots that have a job
You don't need everything you generated. Choose four or five clips that tell the story most clearly. For example: open with the surfer to set the mood, move to the product, add an action shot, and finish on a clean hero shot of the can.
Build a tight sequence
Put the shots in order in your video editor. The order matters more than the number of clips: every shot should move the viewer toward the product. Trim each clip to its best part. A 5-second generation often needs only 1.5–2 seconds in the edit.

Finish with an end card
Close on the product, the campaign line and the action you want the viewer to take, for example CHASE THE WAVE with the logo. Keep it in the same style as the images from the campaign.
Cut versions for each placement
Keep the full edit for horizontal placements, recrop a vertical cut for social, and shorten the sequence when you only have a few seconds. The format changes, but the product, character, colors and visual direction stay recognizable.
