PowerPoint Presentations

Vū Studio includes a native PPTX rendering engine that lets you upload and play back PowerPoint files directly — no conversion, no export to video required. Slides, transitions, animations, and embedded media are all rendered natively.

Uploading a PPTX File

Drag and drop a .pptx file into the Library, or click Upload and select the file. Only .pptx format is supported — legacy .ppt files are not compatible.

Once processed, the file appears in your library as a presentation asset with a slide-count badge.

note

Legacy .ppt files are not supported. Open them in PowerPoint, save as .pptx, then upload.

Casting a Presentation

1. Click the presentation asset in the Library
2. Click Cast to send it to your connected display
3. The Presentation Controls bar appears at the bottom of the screen with Prev / Next navigation and a current slide indicator

Navigating Slides

Method	Action
Prev / Next buttons	Step one slide at a time
Left / Right arrow keys	Same as Prev / Next
Web Player arrow keys	Works in the Web Player — slide state syncs back to Vū Studio

Slide position is synchronized across Vū Studio, the Remote app, Vū Media Server, and the Web Player in real time.

Supported PPTX Content

• Text and shapes (fonts, colors, gradients)
• Images (embedded and linked)
• Embedded videos (play automatically on slide entry)
• Slide transitions
• Entrance and exit animations
• Slide backgrounds (solid, gradient, image)
• Visual adjustments: temperature, tint, treat-black-as-transparency, and key color transparency

Faster Loading

PPTX files load faster thanks to caching. Once a presentation has been loaded on a machine, casting it again resumes playback quickly rather than reprocessing the file from scratch. A quick way to see this: load a presentation into the Remote or cast it to a player, clear playback, then cast it again — it comes back up promptly.

A few things to know about how caching behaves:

• Caching works in the editor and the Remote, and extends to the Web Player and the Vū Media Server.
• Every machine can cache at least one presentation; more powerful machines can cache several at once.
• For a canvas design that contains multiple PowerPoints, the most recently viewed presentation loads the fastest, and others may also be cached depending on the machine.

Auto-Advance When Media Ends

PPTX, video, and gallery elements support a When Media Ends action trigger. Normally an element's action fires on interaction (for example, On Click); with this trigger, you can instead have an action fire automatically when the media finishes — such as advancing to another page when a PowerPoint reaches its last slide or a video plays out.

To set it up in the experience/canvas editor:

1. Select the PPTX, video, or gallery element.
2. In the Actions panel, add an action — for example, Go to Page — and choose the target page.
3. Change the action's trigger from On Click to When Media Ends.

Now the action runs on its own the moment that element's media ends, with no click needed. This is a new trigger option for existing actions, so any action you can normally attach to one of these elements can be fired this way.

note

The When Media Ends trigger is only offered for elements that have an "end" (video, PPTX, and image galleries/stacks). Elements without a natural end point continue to use interaction triggers such as On Click and On Double Click.

Slide Linking

The PPTX engine supports links between slides. Tapping or clicking an asset that links to another slide navigates to the linked slide.

Rendering Accuracy and Odd Slide Sizes

Rendering accuracy has been improved for a range of presentation content. Presentations authored at non-16:9 aspect ratios (for example, 4:3) are fitted to the current screen's frame so the entire presentation stays visible, letterboxed if needed, without losing content. You can then crop, scale, or use treat-black-as-transparency to adjust the look.

Using PPTX in Scenes and Experiences

PPTX assets can be used as the primary asset in a scene, or set as a background or overlay layer alongside other content. They can also be used in Experiences as part of a multi-asset composition.

Visual Adjustments

Like other assets, PPTX files support visual adjustments — color temperature, tint, exposure, opacity, blur, saturation, contrast, and transparency — from the Adjust tab of the side remote while the asset is active. Adjustments change how the presentation is rendered on the display; the uploaded .pptx file itself is never modified.

Key Color Transparency

Treat Black as Transparency renders the black parts of a frame as transparent (Renders black parts of the frame as transparent. Useful for multi-layer setups.). That only helps when the area you want to drop out happens to be black — which, on a slide deck, it usually is not.

Key Color Transparency removes that restriction: you pick the color that should be treated as transparent. A slide with a solid white background, a colored band behind a logo, or a full-slide color overlay can be dropped out on the wall without editing the source file — useful when the presentation is layered over a background, or when the deck came from someone else and you cannot re-export it.

To pick the color:

1. Cast the presentation to a Web Player and open the side remote for that player.
2. Open the Adjust tab.
3. Below Treat Black as Transparency, click the color swatch next to Key Color Transparency (the swatch is labeled Key color). A color picker opens.
4. Choose the color you want to make transparent, in whichever way suits:
   • drag in the saturation/brightness square and the Hue strip;
   • type a value into the hex field (#rrggbb) and press Enter;
   • click one of the swatches under Recent, if you have used the picker before;
   • click the eyedropper button (Pick color from screen) and then click the color anywhere on your screen. The eyedropper is only offered in Chromium-based browsers such as Chrome and Edge — elsewhere the picker still works, just without that button.
5. A Tolerance (%) slider appears once a key color is set, starting at 10%. Raise it to also drop out shades close to the color you picked — helpful when the area is a slight gradient or has compression artifacts around an edge — and lower it to remove only near-exact matches.

To stop keying a color, reopen the picker and click ⊘ None. The Tolerance (%) slider disappears with it.

Points worth knowing:

• Key Color Transparency appears when the remote is connected to a Web Player, and while the player is in 2D mode.
• It is a separate mechanism from Treat Black as Transparency, so the two controls are set independently. While the black toggle is on, the swatch shows black to reflect the transparency currently in effect.
• Like every other visual adjustment, it affects presentation only — the .pptx in your library is untouched, and clearing the key color brings the original colors straight back.
