AI Rain Effect Video Generator
The VdoBloom AI Rain Effect Video Generator turns one still photo into a short video with rain falling through it. Upload a portrait, a street shot, a car at night or a window seat, choose how heavy you want the weather, and the model renders a moving clip where the rain belongs to the scene — drops catching the key light, wet ground picking up reflections, and the cooler, softer contrast that a real downpour gives a camera.
That is the difference between this and dropping a rain overlay onto footage in an editor. An overlay is a flat sheet of particles at a fixed angle; it has no idea where your light source is or what your subject is standing next to. Here the video model regenerates the whole frame as motion, so rainfall sits at the right depth in front of and behind the subject, puddles collect where the ground actually dips, and highlights bloom on wet surfaces instead of sitting on top of them.
Three intensities ship as one-tap templates. Gentle is a soft drizzle under diffused light — quiet, wistful, good for a reflective beat. Dramatic is the cinematic middle: heavier fall, a stronger key, deep shadows behind the subject. Storm pushes it to a full downpour under dark skies. Each template is only a starting prompt, so you can rewrite it — neon signs bleeding into wet asphalt, a warm golden-hour shower, headlights cutting through sideways rain — and the model follows your description rather than the preset.
Rain clips end up as B-roll in lyric videos and music visuals, as openers in short films, and as first-second hooks on Reels and TikTok where the weather does the emotional work before anyone reads a caption. New accounts get 10 free credits, and a 4-second 720p render on Seedance 1.5 Pro costs 6 of them, so the first rain clip costs nothing to try. Be clear on what free means here: renders downloaded on the free credits carry a VdoBloom watermark, and any paid plan downloads the identical file watermark-free.
How it works
- 1
Upload one photo
This tab takes a single image, so whatever you want in the rain has to already be in the frame. A clearly separated main subject matters far more than megapixels — the model needs to work out what the rain is landing on, so skip busy collages and heavily filtered shots.
- 2
Pick a rain intensity
Gentle, Dramatic or Storm. If you are undecided, start with Dramatic: it is the most forgiving of the three and still reads at Reels size, where a light drizzle can vanish into the compression.

Write the light into the prompt
The prompt field controls mood, not just weather. Name the lamp colour, the time of day and the surface underfoot. 'Sodium streetlight, wet cobbles, breath visible' produces a very different clip from the same photo under 'grey afternoon, flat sky, rain on a car roof'.

Choose a model, length and frame
VdoBloom carries 54 video model variants platform-wide; 44 of them — the image-to-video roster — are selectable on this tab. Aspect ratio is a setting on most of them, including Runway, Seedance, PixVerse and Vidu, so you can pick 9:16 for Reels, 16:9 for a YouTube edit or square for a loop. Some image-to-video families, among them Kling 2.6, Hailuo 2.3, the WAN image-to-video variants and ByteDance V1 Lite, expose no ratio control and inherit the shape of your upload, so crop the photo first if you are using one of those.

Generate and check the first frame
Rendering runs on the server, so you can close the tab. When the clip lands, study the opening frame before you watch the whole take: if the subject's edges hold together there, the rest of the shot usually holds too, and if they do not, no amount of re-watching will fix it.

Download and cut it in
Save the MP4 and pull it into any editor alongside your music or dialogue. On a paid plan the file comes down watermark-free, which is what makes it usable as a cutaway. Generating two or three intensities from the same photo gives you matching shots that grade together without extra work.
Why use this tool
Rain with depth, not an overlay
Drops render in front of and behind your subject, reflections land on the surfaces that are actually wet, and the grade cools the way real rain footage does instead of a particle layer sitting flat over the picture.
Three intensities, all editable
Gentle, Dramatic and Storm cover drizzle to downpour, and every preset is an editable prompt rather than a locked filter — change a word and the weather changes with it.
Any weather mood you can describe
Because the prompt is open text, the same tab handles mist, sea spray, monsoon, wet snow or rain lit by neon. You write the conditions and the model builds them into the scene.
44 model variants in one picker
Test the composition on a cheap model, then re-run the shot you like on a higher-fidelity family without leaving the tab or taking out a second subscription. Every variant on this tab shares one credit balance.
Framed for wherever it is going
Vertical, square and wide all come from the same photo on the models that expose an aspect-ratio setting — Runway, Seedance, PixVerse and Vidu among them. A few image-to-video families follow the source photo's shape instead, so crop before you generate on those.
Watermark-free on any paid plan
Paid-plan downloads are plain MP4 with no logo, corner badge or end card, so a rain shot cuts into an existing edit with nothing to hide. Renders downloaded on the 10 free signup credits carry a VdoBloom mark; the same render comes down clean once you are on a plan.
Frequently asked questions
Is the AI rain effect generator free?
The first clip is. New accounts get 10 free credits with no card, and a 4-second 720p image-to-video render on Seedance 1.5 Pro costs 6 of them — a real render at real quality, not a low-resolution preview. That leaves 4 credits, which is enough for a second pass at 480p on the same model for 3, so you can try Gentle and then Storm from one photo before spending anything. It is not unlimited: once the 10 credits are gone you buy a credit pack or move to a plan. Shorter durations and lower resolutions stretch the allowance while you are still hunting for the right prompt.
Do rain effect videos have a watermark?
On a paid plan, no — the MP4 downloads clean, with no logo, corner badge or end card. Downloads made on the 10 free signup credits do carry a VdoBloom watermark, and the same render comes down clean once you are on a plan. The distinction matters more here than on most effects, because rain shots are almost always B-roll: you are cutting them between other footage, and a mark in the corner leaves you either cropping into the composition you just generated or living with a badge that does not belong to your edit. Use the free credits to find the shot, then download it from a plan.
Do I need to sign up?
Yes, but it is email only — no card, no trial to cancel, no approval queue. The account is what the 10 free credits attach to and where finished clips are kept, which matters for this effect because rain shots are usually generated in batches and picked over later; you can come back a week into an edit and re-download the take you passed on the first time rather than paying to generate it again.
How long does a rain video take to generate?
A few minutes for most models at short durations, with longer clips, higher resolutions and the heavier families taking proportionally more. Generation runs server-side and lands in your Creations library, so the sensible pattern for this tab is to fire off Gentle, Dramatic and Storm from the same photo one after another rather than waiting on each in turn — the three arrive together and you choose between them with the actual footage in front of you instead of guessing from the preset name.
What kind of photo works best, and can I use one with two people?
Sharp focus, a clearly separated subject and lighting that already has some direction to it. Night and blue-hour photos are the easiest wins, because rain only reads when it has a light source to fall through — flat midday sun gives the drops nothing to catch. Heavily filtered and motion-blurred shots fight the effect. Two people work fine, but this tab takes one upload, so they have to be in that photo already; name them together in the prompt, for example 'the couple under the umbrella', so the model keeps both as subjects instead of quietly demoting one to background.
Which rain intensity should I pick?
Gentle for a calm, wistful mood; Dramatic for moody cinematic lighting with a strong key; Storm for heavy rainfall under dark skies. A useful rule is that intensity should scale with distance: the further your subject sits from the camera, the heavier the rain needs to be before it registers at all. A tight portrait reads well on Gentle, while a wide street shot often needs Dramatic or Storm before the weather is even visible. None of the three is a locked filter, so if the preset is close but not right, edit its prompt and describe the exact conditions instead.
Which video model is best for rain?
Start cheap, because the first question is whether your framing works at all, not which model renders it best. Seedance 1.5 Pro is 6 credits for a 4-second 720p clip; if you want 5 seconds, ByteDance V1 Pro Fast is 7 at 720p and Runway Gen-3 is 10. Once the shot is right, the thing that separates families on this effect is how they handle specular detail — wet roads, glass, water on skin — and the heavier families hold fine particle motion and moving highlights together better across a longer take. Kling 2.6 image-to-video is 22 credits for 5 seconds at 720p and Runway Gen-4.5 is 48, so treat those as the final pass rather than the exploration.
Are my photos and clips private?
Uploads and finished videos go into your own Creations library, tied to your account, and nothing is published anywhere automatically. Every item has a delete option. Only upload photos you have the right to use — your own shots, or images of adults who have agreed to being animated.
The rain looks wrong, or the render failed — what do I do?
Change one thing at a time and re-run. In rough order of impact: name the surface, such as 'wet asphalt' or 'soaked grass', so the model knows where reflections belong; drop the intensity a step if the subject is disappearing behind particles; and crop tighter if the frame has several competing subjects. If the drops themselves look like they are painted on rather than falling through the scene, add a light source to the prompt — rain needs something to be backlit by. When a generation fails outright instead of returning a poor clip, it appears as failed in Creations and will not recover on its own, so start a fresh render.
Can I generate weather other than rain here?
Yes. The presets are rain, but the prompt is free text and the underlying model is a general video model, so mist rolling through trees, sea spray against a harbour wall, monsoon on a windscreen, sleet under streetlights or heavy wet snow are all one sentence away. The technique is the same whatever the weather: describe the light first, then the particles, then the surface they land on. Clips generated at 9:16 fill a vertical frame on TikTok, Reels and Shorts with nothing to crop, and a set of three at different intensities from the same photo gives you transitions that already match in colour.
