NIM Video is an AI tool that pulls together the best models in one place, Sora 2, Veo 3.1, Nano Banana, Kling, and more, and lets architects and designers turn sketches, renders, and reference photos into cinematic architectural visuals and concept videos in minutes, with no rendering and no software setup. It also has a library of ready-made templates for drone flyovers, timelapses, interior tours, and more. You do not need any AI experience, and I will show you how it works.
Text to image
Start with text to image. I wrote, for example, a modern villa near a lake surrounded by trees. The more detail you give, the more accurate the result, and if you are stuck, the Rewrite button turns a few keywords into a full description. If you have a reference image, tap Describe and upload it, and it writes the description for you. Then pick which AI model to use, I went with Nano Banana, choose the aspect ratio and resolution, and generate. The first result impressed me, the detail, the colours, the lights and reflections were all there.
Getting started
Make an account and you get free credits to experiment right away. The interface is simple, there is one box where you type what you want to create, like most AI platforms.
Turn an image into a video
From the tools on the left you can turn that image into a video. Choose the model, the quality, and how many seconds you want, then generate, higher resolution takes longer. With no camera instructions the motion is gentle, it just captured the setting. So I added camera language to the prompt, wide shot, low-angle, smooth drone flyover, deep focus, cinematic lighting, and the result changed completely. You can direct the angles, movement, depth of field, focus, and style this way. A POV walkthrough prompt across multiple rooms worked beautifully too.
The templates (the fast path)
The templates are where this gets easy. Go to the Templates tab, top left, and choose Architecture and Design: Drone Flyover, Timelapse, Interior Unboxing, and plenty more. No long prompt needed, just upload your image, pick the aspect ratio, and generate, it shows you the credit cost first. The drone result was very accurate, the window reflections on the water, the forest behind, even the same trees appearing at the start and end as the camera turned, which AI usually gets wrong. On the left you can add sound, upscale, or change the clip speed.
The Timelapse template lets you pick a day-to-night or four-seasons transition. I will keep saying it, the reflections are the hard part, accurate reflections are one of the toughest things to fake in renders or video, and these held up, along with the lights coming on at dusk and the sunset colour on the water. For interiors, generate an interior image first, then the Interior 360 template builds a mini tour that even invents the unseen parts of the room in a way that matches the rest of the space, and the Interior Unboxing template makes the playful social-media style clip you have seen everywhere.
Image templates too
There are templates for stills as well: one that adds people to a scene, a render enhancer for a raw 3D view, sketch to render, a miniature model look that genuinely passes for a physical model with fake grass and figures, an isometric view, and a pixel diorama. Most of these need no prompt at all.
Why it is useful to have all the models in one place
The thing I like most is the range of AI models on a single platform, so you can experiment across all of them without switching tools or paying for each one separately. The same prompt run through different models gives you options to choose from.
How architects can actually use it
This is for client pitches, social media, and presentations. Upload a 3D model, get a render, then spin that render into videos. A drone clip presents a villa or housing masterplan in its context and works well for real estate listings. A timelapse shows how a façade or outdoor space reads from day to night or across the seasons. An interior 360 turns one render into a virtual tour for a client who cannot visit in person. Instead of static boards or a PDF, you hand someone a short video that communicates the atmosphere of the design instantly.
My honest take
I am genuinely impressed. A render and video set that normally takes hours across several pieces of software took minutes here, and this is the first time I have gotten AI video results this good. A few honest practicalities though: every generation costs credits, higher resolutions and longer clips take noticeably longer to render, and the quality really does depend on how detailed your prompt is. As with any AI tool, you are trading some fine control for speed. For pitches, content, and quick concept videos, that trade is well worth it.
