How to Turn Revit Renderings Into a Video: Walkthrough Export, Enscape, Veras or Six Stills to AI

A client asks for "something that moves" a week before the owner meeting, and all you have is a Revit model and a folder of renderings. Searching for a way to get there turns up AI vendor pages that skip the menus and forum threads that argue about codecs. This guide puts the four real routes side by side: Revit's own walkthrough export, a rendered camera path from Enscape or Twinmotion, Veras's image-to-video inside Revit, and six exported stills sent to an AI film service, each with its menu path, cost, time and the audience it suits.

Key takeaways

• Revit and Revit LT export a walkthrough as an AVI or an image sequence from the File tab, with no add-in and no extra cost, but not as an MP4.
• Enscape and Twinmotion render a measured camera path from the same model to an MP4, and both let you set a custom resolution for a vertical file.
• Veras generates a short AI clip from one still, from inside Revit or its web app, and lists its Pro plan from USD 348 a year as of October 2026.
• An AI film service such as Arch2Video turns six exported renderings into a roughly 30-second 1080 × 1920 film in an hour or more, with no camera path to build.
• Choose by audience: a measured walkthrough for owner review and planning boards, an AI film for Instagram and early mood, and label any AI motion that reaches a public record.

Four routes from a Revit model to a video

You have four routes, and none of them requires a full animation. Revit itself exports a walkthrough view as an AVI or an image sequence from File tab > Export > Images and Animations > Walkthrough. Enscape or Twinmotion render a camera path from the same model to an MP4 at a resolution you choose. Veras turns one still into a short AI clip from inside Revit, and an image-to-video service such as Arch2Video takes six exported renderings and returns a roughly 30-second vertical film with no model work at all.

Route 1: Revit's own walkthrough export

Autodesk defines a walkthrough as "a simulated tour of a site or building using camera positions placed along a path that you define," drawn in a plan, elevation, section or 3D view, with key frames that change the camera's direction and position (Autodesk Revit LT help, About Walkthroughs, as of October 2026). Once the walkthrough view exists, exporting it is short.

The export steps

As of October 2026, Autodesk's Export a Walkthrough page gives these steps for Revit LT, and they match Revit:

1. Open the walkthrough view (double-click its name in the Project Browser).
2. Click File tab > Export > Images and Animations > Walkthrough.
3. Under Output Length, choose All frames or a Frame range, then adjust Frames/sec; the total time updates as you change the rate.
4. Under Format, set Visual Style, Dimensions and Zoom.
5. Click OK, pick a folder, choose the file type (AVI or an image sequence) and click Save.
6. For an AVI, pick a compressor in the Video Compression dialog.

Autodesk's own advice is to "test various output file and video compression codec types." For an image sequence, "each frame of the walkthrough is saved as an individual file," which you assemble in a video editor.

What it looks like and how long it takes

The export shows the walkthrough exactly as the view does, in whichever visual style you pick, drawn by Revit's display rather than a rendering engine. That is the point for a coordination review and the limitation for anything that has to look finished. Autodesk's companion video page notes that "a frame rate of 15 frames per second is typically adequate for playback on a computer," with 30 fps for video production, and that export time rises with frame count, shaded or rendered styles, shadows and larger pixel dimensions. A short hidden-line fly-through exports quickly; a long realistic one with shadows is a lunch-break job.

Two practical notes. AVI is older than most phones and social apps expect, so convert the file to an MP4 in your editor before it leaves the office. And Revit sizes the export from the view's crop region, so for a 9:16 file set a tall crop boundary on the walkthrough view before opening the dialog, then check the Dimensions fields.

Route 2: Enscape or Twinmotion from the same model

If the studio already renders stills in Enscape or Twinmotion, the fastest path to a finished-looking video is a camera path in that renderer: the model stays the source of truth and the materials and lighting you set for the stills carry over.

Enscape runs inside Revit as an add-in. Chaos's export options overview, last updated February 16, 2026 and read as of October 2026, lists video export from the Export button in the Video Editor as an MP4, with resolution, compression quality and frame rate as the settings, and notes that defaults "can also be specified in the Visual Settings dialog." The same page lists a Revit-specific "Render Image (into document)" option and still-image export in PNG, JPG, EXR or TGA at Full HD (1920 × 1080) by default, up to 8192 × 8192 pixels.

Twinmotion's route, per Epic's Exporting media locally page as of October 2026: click Export in the Footer, click the Plus button next to Video to select clips, click Video to adjust global settings, click Start export and choose a folder. Epic's video export settings page lists MP4 as the default format with PNG and EXR sequences as alternatives, presets of 2K Full HD (1920 × 1080), 4K UHD, 8K, 16K or custom, frame rates of 25, 30, 60 or 120 fps with 30 as the default, and motion blur off by default.

Both tools render landscape unless told otherwise. The custom-resolution values, keyframe timing and safe-zone math for a 9:16 file are in how to export vertical video from Enscape, Lumion, Twinmotion and D5. Expect real GPU time, scaling with clip length and quality, and as long again placing keyframes so the camera doesn't clip a wall.

Route 3: Veras image-to-video inside Revit

Veras is an AI rendering tool that, according to its product page on archvision.com as of October 2026, "works directly inside Revit, SketchUp, and Rhino" and includes an "Image-to-Video Generation" feature that converts "still renders into short, dynamic animations that showcase movement, lighting shifts, or environmental changes." Chaos's own Veras page describes the trigger as "a prompt or preset" and lists Revit, SketchUp, Rhino, Archicad, Vectorworks, Forma and Allplan as hosts, plus availability through Enscape, V-Ray, Corona and a web app. For how Veras now ships alongside Chaos's render engines, and what to let an AI tool touch in a still, see Vectorworks 2027, Veras and what to fix before you animate.

Pricing on the archvision page, as of October 2026: Veras Pro "from $348.00 / year," with 2,000 credits and "up to 200~ AI videos monthly"; Veras Ultra lists 6,000 credits and up to 600 videos monthly without a displayed price. Chaos's Veras for Revit page shows a 14-day free trial and USD 348 a year after it. Neither page states a clip's length, resolution or format, so check those in the trial before planning a deliverable around them.

Each clip starts from one still. A 30-second piece means several clips, one per view, each with its own camera instruction, cut together in an editor. The result is an AI interpretation of your rendering, not a path through your model: straight lines can drift, and anything off the edge of the frame is invented. That makes Veras useful for mood options on a view you already like, and a poor substitute for a walkthrough someone will measure against.

Route 4: six exported renderings to an AI film

The fourth route skips the camera path and the editor. You export six finished views, upload them, and get back a film. It suits a studio that has renderings but no time, and works the same whether the stills came from Revit's renderer, Enscape, Twinmotion or a photographer.

Arch2Video takes exactly six images from one project, as JPG, PNG or WebP at full resolution, and delivers a 1080 × 1920 vertical MP4 of about 30 seconds: six connected five-second scenes, an original soundtrack (Still Air, Quiet Piano, Concrete, or none) and an optional studio logo, with a no-logo version included whenever you add one. Its AI director plans the scene order, so the film may not follow your upload order. Generation usually takes an hour or more and you are emailed when it is ready; after that you can switch the soundtrack or logo and re-export without using another video credit. Your account's first video is free, made the same way as a paid one, with a small arch2video.com watermark that any plan removes at no extra cost. After that, plans are month to month: Studio at USD 49.90 a month for four videos, Practice at USD 99.90 a month for eight, and an extra video at USD 30 for active subscribers, with unused extras carrying over. You can upload the six images first and choose a plan before the video is created.

Two things it does not do. It works from images, not from your Revit model, so there is no measured walkthrough, no text prompt box and no API. And every film includes a small cast of original, fictional people in at least one scene, while people in your own images are not animated. Review the film before it goes anywhere, and present unbuilt work as concept work.

Exporting the six stills from Revit

For Revit's own renderings, Autodesk's Export a View to an Image File page (read as of October 2026) gives the path: File tab > Export > Images and Animations > Image, then under Export Range choose Current window, Visible portion of current window or Selected views/sheets, and under Image Size either Fit To with a pixel value and a Horizontal or Vertical direction, or Zoom To with a percentage and a DPI value. Export at the largest size you have patience for; the AI reads detail from the image.

Pick the six as a set: an approach, a wide exterior, an entry, two interiors and a detail cover a project from the outside in. A six-view set that covers a project from exterior to detail explains the logic, and a floor plan can take one slot, where it's treated as a document and given a slow pan.

Pick a route by audience: owner review, planning board, Instagram

The question that settles the choice is who is watching and what they will do with it.

Owner review. An owner walking the design wants the corridor width, the view from the primary bedroom and the stair in section, and may ask you to stop and back up. That is Route 1 or Route 2: a camera path through the actual model. Revit's export is enough for a working session; an Enscape or Twinmotion path suits the meeting where finishes get approved. An AI film can open the meeting as a mood piece, but it cannot answer "is that door really three feet wide."

Planning board or design review. A public hearing puts the video on the record, and commissioners and neighbors will compare it to the drawings. Use a rendered camera path or a Revit walkthrough in a realistic style as the exhibit, and keep any AI motion as a clearly labeled supplement. How to use a rendering video for a planning commission presentation covers running time, what to show and the disclosure line for the record.

Instagram, LinkedIn and the website. Here the audience scrolls, the frame is vertical and nobody measures anything. Route 4 is built for this: six stills in, a 9:16 film out, with no keyframes. A Twinmotion or Enscape export at 1080 × 1920 reaches the same place with more control and more of your time. For the wider set of options, see how to turn architectural renderings into video, with or without a 3D model; for the budget comparison against a commissioned animation, see architectural animation vs. AI video.

Disclosing AI motion in design review

Whenever an AI-generated clip reaches a client meeting, a board packet or a public hearing, say so on the slide or in the caption, name the source images, and present unbuilt work as a concept. Mention that the people in the film are fictional and that the camera motion interprets the renderings rather than tracing the model. Then keep the measured walkthrough or the drawings as the document of record, so the AI film is context rather than evidence.

Frequently asked questions

Can Revit export an MP4 directly?

No. As of October 2026, Autodesk's Export a Walkthrough page lists two output types, an AVI file or an image sequence, and for AVI you pick a compressor in the Video Compression dialog. To get an MP4, convert the AVI in your video editor or a free converter, or export an image sequence and assemble it. Enscape and Twinmotion export MP4 directly, and an AI film service delivers an MP4.

Does Veras work with Revit LT?

Chaos's Veras for Revit page says, as of October 2026, "Upload your Revit LT model to Veras and render in seconds," which describes the web-app route rather than an add-in inside Revit LT; the archvision.com product page lists Revit, SketchUp and Rhino as the hosts it works directly inside and doesn't mention Revit LT. On an LT seat, confirm the workflow in the trial before buying. Revit LT's own walkthrough export and the six-stills route both work without an add-in.

Can AI video replace a Revit walkthrough for a planning board?

Not as the exhibit of record. An AI film interprets six stills and invents whatever sits off the edge of each frame, including a small fictional cast, so it can't be measured against the drawings the way a camera path through the model can. Use a rendered walkthrough or a Revit export as the primary video, and if you show an AI film, label it as AI-generated concept motion in the packet and on screen.

How many renderings do I need for a 30-second film?

With Arch2Video, exactly six: each becomes one connected five-second scene, and the six add up to about 30 seconds. With a hand-driven image-to-video tool such as Veras, each still produces one short clip, so plan one image per clip and enough clips to fill the length you want, then cut them together. Either way, six views covering approach, exterior, entry, interior and detail make a better set than six variations of one angle.
