How to Export a Vertical 9:16 Video From Enscape, Lumion, Twinmotion or D5 for Instagram Reels

A renderer can make a beautiful landscape movie that becomes almost useless when cropped for a phone. The camera follows the corridor, but the vertical crop removes the doorway that explains where it leads. Fix that before rendering. This guide separates the renderer's output controls from the decisions you make as an editor: portrait composition, a short camera path, a practical delivery file, and a playback check. Vendor documentation was checked in October 2026; menu labels can differ between versions and host applications.

Key takeaways

• Set the portrait frame before placing or approving camera keyframes.
• Use 1080 × 1920 as a practical vertical delivery target, with 30 fps when that suits the source and destination.
• Enscape has custom resolution controls; Lumion supports a 9:16 movie aspect ratio; Twinmotion has custom output dimensions.
• D5 output limits depend on the account, and its current Community license is for non-commercial use.
• A native model animation preserves modeled geometry; generative motion from stills is a different, interpretive product.

The shortest route to a usable vertical export

Compose and preview the camera in a 9:16 frame, render a short test, then export a complete movie using the same dimensions. Check the actual downloaded file on a phone before posting it. The main advantage of composing vertically in the renderer is that you can change the camera position instead of sacrificing important parts of the architecture to a later crop.

For a general social delivery copy, our starting recommendation is a 1080 × 1920 MP4 encoded with H.264. That is an editorial delivery choice, not a claim that every renderer natively uses that codec or every platform requires the same specification. In particular, a filename ending in MP4 identifies the container, not the codec inside it. Convert a renderer export in your editor if the destination rejects it.

Meta's Reels guidance emphasizes vertical creative, audio and keeping important elements clear of interface overlays. Preview the actual placement; do not assume a title at the bottom of the editing canvas will stay visible after upload. The accompanying Instagram export guide covers preparing source images.

Enscape: custom dimensions before final keyframes

Chaos' Video in Enscape documentation describes a Video Editor export dialog that can override resolution, aspect ratio and frame rate. Choose Custom for the dimensions rather than accepting the current window size. Enter the portrait width and height, then return to the preview and check both ends of every movement.

The same documentation distinguishes compressed MP4 exports from the Lossless option, which produces PNG frames. An image sequence is useful if you plan to finish the movie in an editor, but it is not a ready-to-upload social video. Put a sequence in its own folder and confirm available disk space before rendering. Test a short section first so an unexpected output format does not consume your entire afternoon.

Our camera recommendation is to move a short distance through a composition that already works as a still. If the subject is a tall stair, frame its start and landing. If the subject is a kitchen, keep the counter edge visible throughout the move. A sweeping rotation is harder to read on a narrow screen and makes accidental wall intersections easier to miss.

Lumion: keep the first clip's aspect ratio deliberate

Lumion's aspect-ratio reference lists 9:16 in Photo and Movie Mode for Lumion 2023 and newer. The portrait Full HD movie dimensions are 1080 × 1920. For a complete movie, the first clip's aspect ratio controls the clip set's output.

That last detail matters when you reuse an old landscape project. Set the first clip correctly, then inspect every subsequent composition. A camera that was framed to show two building wings may need a different position to show one wing well in portrait. Do not treat changing the aspect-ratio icon as completion of the creative work.

For a short test, choose a clip with both foreground detail and a long straight edge. Review its beginning, middle and end. Our editing recommendation is to use consistent movement speed between clips, avoiding an abrupt jump from a static room to a fast exterior orbit. Save the approved portrait version separately from the original landscape movie so later revisions do not overwrite the wrong delivery.

Twinmotion: custom output and the Filmback interaction

Epic's video export settings distinguish global export settings from settings for an individual video. Select the video in the Media dock and check its Output size in the Video settings added to Ambience. Custom dimensions let you specify a portrait output.

If Filmback is enabled, the selected filmback preset constrains the aspect ratio: changing the width keeps the height proportional. If the height seems locked, inspect that setting before assuming the application cannot render portrait. Keep the camera's intended framing consistent with the output, then select the required video or parts in the Export panel.

As an editing workflow, keep a low-cost preview separate from the final render. Check whether reflections and moving objects look stable before increasing quality. A technically high-resolution export does not repair a camera passing through a chair or a dramatic exposure jump at a cut. Use a short review loop while the model is still open and corrections are straightforward.

D5: confirm the current account and export controls

D5's video rendering guide describes its video workflow and account-dependent output limits. The current documentation lists video output up to 4K for individual accounts and up to 8K for team accounts. Those are maximums, not a reason to render every Reel at the highest setting.

The text documentation checked for this article did not establish one universal portrait-menu label across D5 versions. In your installed version, inspect the video output dimensions and camera preview; require the rendered file to have the intended portrait dimensions before approving a batch. If the controls only expose a landscape preset, consult the version-specific help rather than stretching the image in an editor.

Check licensing as well as resolution. D5's current pricing FAQ says Community is designed for learning, personal projects and evaluation; commercial or professional work requires Pro. Older forum replies describing unrestricted free commercial use do not override that current statement. Confirm the license covering the project before exporting client marketing.

Compare the four routes before rendering overnight

When six stills are the better starting point

If the model is archived, incompatible with your current software, or no longer available, rebuilding a native camera path can be disproportionate to a short marketing request. A set of approved stills can support a simple edited sequence or generative motion. The native animation versus AI comparison explains the accuracy tradeoff.

Arch2Video takes exactly six images from one project and produces an approximately 30-second, 1080 × 1920 vertical film with music options and an optional logo. It interprets the images; it does not reconstruct a measured model walkthrough. It also includes original fictional people in at least one scene, so it is unsuitable if your brief requires an empty building throughout. Generation usually takes an hour or more, and availability can affect when production starts. Allow review time rather than promising a same-hour delivery.

For either route, retain the source stills, approved model views and final export. Watch the full file with sound and once without it. Keep project facts and necessary disclosure readable without narration. Then use the Reels planning guide to decide what the short film should communicate, rather than adding every camera angle available.

Frequently asked questions

Can Enscape export a 9:16 video directly?

Its documented Custom resolution controls allow a portrait width and height. Compose with that output in mind, verify the rendered file, and check the codec if a platform refuses the MP4. The export dialog and available options can vary by version.

What bitrate should I use for an Instagram Reel export?

There is no universal number established here for every source and renderer. Start with your editor's high-quality H.264 preset at the delivery dimensions, inspect fine lines and gradients, and adjust if compression damage is visible. Avoid repeatedly recompressing an already compressed social download.

Is D5 free for professional client work?

The current pricing FAQ says D5 Community is for non-commercial uses and that professional or revenue-generating work requires Pro. Check the current agreement for your situation; a free download alone does not establish a commercial license.

Do I still need AI video if I own Lumion?

Not necessarily. If you have the model, a working scene and time to set the cameras, native animation may be the better fit. AI from stills is useful for a different situation: you have approved images and want an interpretive short film without reopening the model.
