Kapwing

Use Kapwing for a video draft that will need detailed finishing. Its Kai guide describes attaching reference images, video or audio, then reviewing a storyboard with script, B-roll, narration and aspect ratio. State which supplied asset belongs in each scene before generating.

The text-to-video workflow continues in the same editing studio: swap clips, adjust narration, add branding and work on the timeline. For a product demonstration, keep the real product image beside the draft while checking each generated visual.

Kapwing’s subtitle tools let you correct the transcript, timing and styling, then export subtitles separately or embed them in the video. Check names, numbers and line breaks while watching the picture, not only by reading the transcript.

Our suggested first output is one finished vertical clip. Watch it at phone size with sound off, then with sound on; check whether captions cover the product or the closing action. Continue with the first product video guide.
