5 prompt results (Kling vs Wan)

1) Perfume bottle hero shot (reflections)

Prompt: 9:16 commercial product video. A premium matte-black perfume bottle on dark wet slate. Soft rim light, realistic reflections. Slow camera push-in with a gentle turntable rotation. Clean background, no text.

Settings: Kling mode=std, duration=5s, ratio=9:16, sound=off, scale=0.5. Wan mode=std, duration=5s, ratio=9:16, resolution=720P, audioEnabled=false.

Kling V3 Omni	Wan 2.6
Prompt 1 (Kling): perfume bottle hero shot.	Prompt 1 (Wan): perfume bottle hero shot.

Kling keeps a matte cylindrical bottle consistent across frames, with stable lighting and reflections.
Wan renders a glossier rectangular glass bottle look with strong highlights. Framing stays steady.
Both clips look ad-usable for a clean product hero shot.

2) UGC hand demo (small object handling)

Prompt: 9:16 UGC phone video in a bright kitchen. A hand opens a wireless earbuds case and takes one earbud out. Slight handheld shake, natural skin texture. Simple background, no text.

Settings: Kling mode=std, duration=5s, ratio=9:16, sound=off, scale=0.5. Wan mode=std, duration=5s, ratio=9:16, resolution=720P, audioEnabled=false.

Kling V3 Omni	Wan 2.6
Prompt 2 (Kling): earbuds case open + grab.	Prompt 2 (Wan): earbuds case open + grab.

Kling stays stable across the open-and-grab sequence, with normal-looking hands in the sampled frames.
Wan looks coherent, but a couple frames show small geometry changes on the earbud/case.
For UGC hands, keeping the action list short helps both models.

3) Running shoes turntable (geometry consistency)

Prompt: 9:16 studio product ad video of a pair of running shoes on a turntable. One smooth orbit around the shoes. Sharp fabric texture, clean highlights, soft shadow. Minimal background, no text.

Settings: Kling mode=std, duration=5s, ratio=9:16, sound=off, scale=0.5. Wan mode=std, duration=5s, ratio=9:16, resolution=720P, audioEnabled=false.

Kling V3 Omni	Wan 2.6
Prompt 3 (Kling): shoe turntable/orbit.	Prompt 3 (Wan): shoe turntable/orbit.

Kling keeps the shoe form consistent across frames and looks safe for a generic product spin.
Wan looks more stylized and detailed, but the midsole/shape shifts across frames and a brand-like side mark appears.
If the product must stay exact, watch for shape drift and accidental branding on footwear prompts.

4) Stop-motion wrapper reveal (style lock)

Prompt: 9:16 stop-motion paper cutout ad scene. A chocolate bar wrapper flips open and a paper chocolate square pops out. Handcrafted paper texture, simple loop-like motion. Clean composition, no text.

Settings: Kling mode=std, duration=5s, ratio=9:16, sound=off, scale=0.5. Wan mode=std, duration=5s, ratio=9:16, resolution=720P, audioEnabled=false.

Kling V3 Omni	Wan 2.6
Prompt 4 (Kling): paper cutout wrapper reveal.	Prompt 4 (Wan): paper cutout wrapper reveal.

Kling keeps the wrapper and chocolate piece coherent across frames, with a clean minimal look.
Wan shows readable wrapper text (“Chocolate”) even though the prompt asked for no text.
If you need brand safety, add a stronger negative prompt for text/logos and keep packaging generic.

5) Busy neon subway (crowd + signage)

Prompt: 9:16 cinematic handheld shot on a crowded subway platform at night. Neon lights reflect on a wet floor. People walk past the camera. One forward tracking move, realistic motion blur, no readable text.

Settings: Kling mode=std, duration=5s, ratio=9:16, sound=off, scale=0.5. Wan mode=std, duration=5s, ratio=9:16, resolution=720P, audioEnabled=false.

Kling V3 Omni	Wan 2.6
Prompt 5 (Kling): crowded subway platform.	Prompt 5 (Wan): crowded subway platform.

Kling lands a busy crowd scene, but the sampled frames show more chaos: heavier blur/ghosting and more visible signage.
Wan looks more composed and cinematic across frames, with steadier framing and fewer obviously readable signs.
For public scenes, always watch for readable signage and recognizable faces if the clip goes into a real ad.

Verdict (based on these 5 tests)

If the goal is clean product shots and simple hand demos, Kling V3 Omni looks steadier and more “safe” across frames.
If the goal is a more cinematic vibe for environments (like the subway test), Wan 2.6 looks more composed in this set.
Both can surprise you with accidental text or brand-like marks. Negative prompts help, but reviewing frames before shipping is mandatory.

Prompt tips that improved stability

Write 2-4 short sentences. One subject, one camera move.
Say “no text” and also add a negative prompt for text, watermark, and logos.
For hands: keep the action list to one clear action (open, grab, place). Avoid multi-step instructions.
For product spins: keep the background minimal and avoid brand names.

Try the prompts

Copy the prompts above, keep the settings the same (9:16, 5s, 720p, audio off), and swap only one variable at a time (ratio, duration, or camera move). That makes it easy to see what actually changes.
