How to Make an AI Kissing Video from a Photo with VdoBloom

Step-by-step guide to VdoBloom's Kissing Video effect: one photo or two, the Romantic/Passionate/Sweet/Dramatic templates, real credit costs from 10 credits, and how to keep both faces recognisable.

To make an AI kissing video on VdoBloom, open the Kissing Video tab, upload either one photo that already contains both people or two separate portraits, pick one of the four templates — Romantic, Passionate, Sweet or Dramatic — choose a video model and length, then generate. The cheapest setup that works well is Runway Gen-3 at 720p for 5 seconds, which costs 10 credits, or $0.50 at Lite-plan rates — exactly the balance a brand-new free account starts with, so your first kissing video can cost nothing.

You must have the consent of every real person whose photo you upload. A kissing video puts two identifiable faces into an intimate moment, so only use photos of yourself and of people who have agreed to it. Do not upload photos of minors, and do not upload someone else’s partner, ex or a stranger from social media.

What the kissing effect actually does

The Kissing Video tab is not a face swap and it is not a stock clip with your face pasted on. VdoBloom runs the kissing effect through a keyframe pipeline: a WAN 2.7 pass first builds a single clean keyframe in which both subjects stand together in a medium close-up with matched lighting, shared white balance and believable eye lines, and only then does a video model animate that frame into the kiss. The keyframe prompt carries a hard identity lock — preserve each subject’s exact face, age, skin tone, hairstyle and body proportions, no face swaps, no added people, no extra limbs, no text or watermarks.

That two-stage design is why the kissing tab keeps a smaller model roster than most other effects. It is also why results are far more stable when the two faces you upload are lit in a similar way. The model has to fuse two photographs into one believable scene before anything moves.

What photo works best

  • Head-and-shoulders to upper-body framing. The keyframe is composed as a medium close-up. A full-body shot gets cropped in hard; a tight face-only crop leaves no headroom for the lean-in.
  • Both people facing roughly toward the camera. Profile shots give the model no information about the far side of the face, and that is the side that turns during a kiss.
  • Similar light on both photos when you upload two. Daylight portrait plus flash-lit nightclub selfie is the single most common cause of a mismatched, pasted-on look.
  • Clean, simple backgrounds. Busy backgrounds warp when the camera pushes in.
  • No sunglasses, no heavy motion blur, no group photos where the tool has to guess which two people you meant.

If your source photo is dark, low-resolution or cluttered, fix it first in the AI image editor and then feed the cleaned-up version into the kissing tab. Five minutes of image prep beats three regenerations.

The four templates

Each template is a full prompt, already written and tuned, that you can still edit before generating:

  • Romantic — a soft, unhurried lean-in. Warm golden-hour light, shallow depth of field, a gentle push-in that settles as their lips meet. This is the safe default.
  • Passionate — an intense kiss with one hand rising to the other’s face or neck. Tighter framing, richer contrast, a slight handheld drift that adds urgency without shake.
  • Sweet — a light, affectionate kiss with smiles and foreheads resting together afterwards. Soft even daylight, airy pastel tones, a steady wider frame. Best for anniversary and family-friendly posts.
  • Dramatic — the closing beat of a film. Strong directional key light with deep falloff, a slow orbiting camera move, faint atmospheric haze, widescreen and theatrical.

Credit cost by model and setting

An effect video is billed at the rate of whichever video model you select, at the duration and quality you choose — the keyframe step is not billed separately. One credit is $0.05 on the Lite plan ($15 for 300 credits), so the dollar column below is the honest cost of one finished kissing clip.

Two practical readings of that table. First, a kiss is a five-second moment — ten seconds of the same kiss almost always looks padded, so the 5s rows are the ones that matter. Second, doubling your spend does not double the kiss quality; it buys sharper skin detail and steadier camera motion. Start on Runway Gen-3 720p at 10 credits, and only move up once you know the framing and template are right. Full plan and pack pricing is on the pricing page, and credit packs from $2.49 never expire.

The exact steps

  1. Open the Kissing Video tab.
  2. Choose one photo or two. One photo containing both people keeps their real relative scale and lighting, which usually looks better. Two photos give you control over who appears.
  3. Upload. With two photos, the first slot is Person 1 and the second is Person 2.
  4. Pick a template. Romantic for a first attempt.
  5. Set model, duration, quality and aspect ratio. Use 9:16 for Reels, TikTok and Stories; 16:9 for YouTube.
  6. Edit the prompt only if you want to change setting or mood — leave the identity-preservation wording alone.
  7. Generate, then wait. Credits are deducted when the job starts.
  8. Download. Free accounts get a watermark; any paid plan gives you a clean file with commercial rights — see watermark-free export.

How to prompt it well

The templates already contain everything the model needs about identity and blending, so use your edits for the things they cannot know: the place and the light. Add a short clause such as at a rainy bus stop under a streetlight, or on a beach at sunset with wind in her hair. Keep it to one added sentence. Long stacked prompts fight the identity lock and start drifting the faces.

Things not to write: named celebrities, anything explicit, ages, or instructions to change a person’s body. VdoBloom’s flexible content tier covers swimwear, dance and fashion, and the kissing effect is built to stay tasteful; explicit content stays blocked regardless of model.

When to pick a different tab instead

  • You want warmth without the kiss — use Hugging Video, same two-photo flow.
  • You only have one person and want a playful gesture — use Blowing Kiss, a single-photo direct effect.
  • You want a fun, obviously-AI bit where several people kiss your cheek — use Kiss Me More, which has Kisses from Girls and Kisses from Boys variants.

Troubleshooting

Faces drift or merge. Almost always a framing problem. Re-crop both photos to head-and-shoulders and re-run. Do not fight it by adding more identity words to the prompt.

One person looks pasted in. Mismatched lighting between the two uploads. Either use a single photo of both people, or colour-match the two shots before uploading.

The kiss never lands. At 10 seconds the model often spends the clip circling. Drop to 5 seconds.

The result is stiff. Switch template before switching model — Passionate and Dramatic carry far more camera motion than Sweet.

Frequently asked questions

Can I make an AI kissing video from one photo?

Yes, if that one photo contains both people. The tab has a photo-count toggle: one photo of two people, or two separate portraits. It cannot invent a second person from a solo photo on this tab.

How much does one kissing video cost?

From 10 credits ($0.50) on Runway Gen-3 at 720p for 5 seconds, up to 96 credits ($4.80) for 10 seconds on Runway Gen-4.5. New accounts get 10 free credits with no card, which covers one clip at the entry setting.

Will the video have a watermark?

Free-tier downloads are watermarked. Every paid plan, from Lite at $15/month for 300 credits, downloads watermark-free with commercial rights. Annual billing brings Lite to $10/month.

Does it keep our real faces?

That is the explicit goal of the keyframe prompt, which locks face, age, skin tone, hairstyle and proportions. Likeness holds well on clear, well-lit, forward-facing photos and degrades on profiles, sunglasses and low-light shots.

Is it free to try?

Yes. Ten credits at signup, no card required — enough for one 5-second kissing video at 720p. See the free AI video generator for what the free tier covers.

What aspect ratio should I use?

9:16 for TikTok, Reels and Stories; 16:9 for YouTube. Runway Gen-3, Gen-4 Turbo, Gen-4.5, PixVerse v4.5 and Vidu Q3 Turbo all expose the ratio selector; Kling V2.5 Turbo does not and inherits the shape of your photo.
