How to Make the AI Zombie Trend Video in Google Flow (Veo 3.1)

Google Flow is Google's AI filmmaking app for its Veo video models, and it's one of the most searched tools alongside the AI zombie trend. It makes great-looking, great-sounding clips — but a Veo clip is at most 8 seconds, and the zombie video needs about 15. So in Flow you make the story as two clips, the zombie scene and the memory, and join them on the hug.

The plan: two clips, one cut

• Clip 1 (8 s) — the turn. Cold cabin, the gun, the infected face, the gun comes down, the hug.
• Clip 2 (8 s) — the memory. The same hug in warm sunlight, both healthy, then the spin.
• The cut. Join them where the hug poses match. Done well, it looks like one shot changing worlds.

What you need

• Photo 1: the survivor — usually you. Front-facing, face fully visible.
• Photo 2: the one who turns. One person per photo, ideally on a plain background — Flow's own guidance says ingredients work best that way.
• Adults only. Don't use photos of children; Google's policies block them.
• A Google account with Flow access and enough credits for both clips plus re-rolls.

Step by step

1. Open Flow and start a new project. Choose Ingredients to Video as the mode. Ingredients are reference images Flow keeps consistent across shots; you can add up to three per prompt.
2. Add both photos as ingredients. Give them a moment to process.
3. Pick the model. Veo 3.1 Fast is the sensible default for re-rolls; switch to Veo 3.1 Quality for the final take if you have the credits.
4. Set 9:16 (portrait) for TikTok and Reels, and the longest length, 8 seconds.
5. Paste prompt 1 and generate. Make two or three versions and keep the one where both faces hold up.
6. Make clip 2 with the same ingredients and prompt 2. It opens on the hug, so it continues where clip 1 ends.
7. Join the clips. Add both to a scene in Flow, or download them and join in CapCut. Trim so the cut lands on the hug.

Cinematic, photorealistic, handheld camera. Cold blue-grey light. An abandoned wooden cabin at dusk during a zombie apocalypse.
The man/woman from the first ingredient stands in a broken doorway aiming a rifle, hands shaking.
The person from the second ingredient turns toward them, infected: pale grey skin, dark veins around clouded eyes, torn dusty clothes, no blood, no gore. They stop, recognising each other.
Close-up of the first person, tears on their face. They lower the rifle and let it fall, step forward and hug the infected person, who slowly hugs back.
Keep both faces exactly like the ingredients. Sound: wind, creaking wood, heavy breathing, one low groan. No music, no dialogue, no subtitles.

Cinematic, photorealistic, smooth steady camera. Warm golden-hour light, a sunlit wildflower meadow, tall grass moving in a soft breeze, gentle lens flare, warm film colour.
Opening on the person from the first ingredient and the person from the second ingredient already holding each other in a tight hug, both healthy and human, clean clothes.
They pull back, smile, and the second person lifts the first and spins them around, both laughing.
Keep both faces exactly like the ingredients. Sound: birdsong, rustling grass, soft laughter. No music, no dialogue, no subtitles.

Replace "The man/woman" in prompt 1 with whichever fits photo 1. Veo follows a plain description of who is who better than labels.

Making the cut land

• Match the hug, not the clock. Find the frame in clip 1 where the hug settles and the frame in clip 2 that looks most like it. Cut there.
• Add one flash frame or a 2–4 frame cross-dissolve if the poses don't quite match — it reads as a memory, not an error.
• Want a frame-perfect match? Take the last frame of clip 1, edit it into a sunny, healthy version in an image tool, then use Frames to Video with that image as the start frame for clip 2. It costs one more step but the cut becomes seamless.

What it costs

Flow runs on credits that come with Google AI plans. At the time of writing, a Veo 3.1 Fast clip costs 20 credits and a Veo 3.1 Quality clip 100 credits on non-Ultra plans. Google AI Pro ($19.99 a month) includes 1,000 monthly credits on top of a small daily allowance, so two Fast clips with a few re-rolls each comes to roughly 100–150 credits. The free daily allowance may not cover video at busy times. Prices were checked in October 2026 and change often — check the plan page before you subscribe.

Flow-specific problems

• The face changes between clip 1 and clip 2. Use the exact same ingredients for both, and keep the hair and clothes descriptions identical.
• Veo adds music or speech. Veo generates audio by default. Keep "No music, no dialogue" in both prompts, or mute the clips and add the trending sound in CapCut.
• Your photo is rejected. Flow refuses some uploads under Google's policies. Try another photo of the same adult — face visible, nothing in front of it.
• The infected look is too mild. Veo plays it safe. Name the details (grey skin, dark veins, clouded eyes) rather than just "zombie".

Our zombie video generator makes the whole 15-second story in one render — no stitching, no matching the hug by hand. Two photos, pick the memory, first video free, then from $6.99. To do it in other apps, see the Higgsfield guide, the PixVerse guide or how to make the AI zombie video.
