Or pick it from the model menu in the app. Make a 15 second UGC ad for our olive oil with Kling 4.0, kitchen at golden hour, 9:16. Render the packshot spin on Kling 4.0 and post it to TikTok and Reels. Redo yesterday's ad on Kling 4.0 with the new label. ## Getting the best out of Kling 4.0 - Describe one continuous camera move and where it ends. The model renders motion, not a shot list. - Attach the real product photo as a reference and ask for it matched exactly. Never describe a lookalike. - Name colours in words. A hex code turns into text on screen. - Keep spoken lines short. Roughly two words per second is what a clip can carry cleanly. - Ask for the placement's ratio up front (9:16 for Reels and TikTok) instead of cropping afterwards. Make a video ad with Kling 4.0. Start free, and every feature is on every plan.
