Every Spectra Block Loads Faster, Without a Slower Host or a Video Bill
Spectra builds galleries, sliders, background video, and popups in the block editor, and every image or MP4 lands on your server. Infinite Uploads moves it to cloud storage and a CDN, optimizes images to AVIF and WebP on the Business plan, and serves self-hosted video from the CDN.

Spectra and Infinite Uploads: Galleries, Popups, and Video Without the Storage Bill
Spectra gives the block editor real design tools: a Container block with image and video backgrounds, an Image Gallery, a Slider, Modal and Popup Builder blocks, Info Box, and Testimonials, plus a Design Library of starter templates. Every image and self-hosted video lands on your server, and a gallery-heavy or video-heavy page is exactly what drags down Core Web Vitals.
Infinite Uploads offloads all of it to cloud storage and a CDN, converting images from every block to AVIF and WebP. Self-hosted background video in a Container serves from the CDN as-is instead of stalling on shared hosting, and Video Cloud handles adaptive streaming for Video Library uploads, included on every plan. Folders and search work inside the media popup.
Spectra keeps doing everything it does: every block, style setting, and the Design Library render exactly the same. Infinite Uploads only changes where the files live and how fast they arrive, so a popup-heavy or gallery-heavy page loads fast and one bill covers storage, video, and CDN bandwidth instead of three.
Four Problems Infinite Uploads Solves for a Spectra Site
Most offload plugins move files and stop. Here's what matters when the files are your galleries and page designs.
Gallery, Slider, and Container Pages That Actually Pass Core Web Vitals
An Image Gallery block, a Slider full of product photos, and a full-width Container background image can be the heaviest page on the site. Infinite Uploads converts every image to AVIF and WebP, right-sizes it, and serves it from the CDN edge closest to each visitor.
Container Background Video That Doesn't Stall Shared Hosting
A self-hosted MP4 background in a Container block normally plays straight from your server. Infinite Uploads serves that same file from the CDN instead, so nothing stalls. For video visitors actually watch, upload to the Video Library for adaptive streaming.
Design Library Starter Templates Stop Bloating Your Media Library
Importing a Design Library starter template, built with the separate Astra Starter Templates plugin, pulls its demo images straight into your Media Library in one click. Infinite Uploads offloads them the same as any upload, and Media Folders keep the template's assets separated from your own.
Testimonials, Info Boxes, Modals, and Popups, Organized and Off Your Server
Testimonial avatars, Info Box icons and images, Modal background images, and Popup Builder graphics all pile up in the same Media Library as a site grows. Sync once, and everything moves to cloud storage with folders, search, and sort intact, then free up local storage from Infinite Uploads settings.
Why Spectra Builders Pair It With Infinite Uploads
One Bill Instead of a Video Account and a CDN Invoice
Spectra has no native cloud storage or CDN, so a gallery-heavy or video-heavy site either fills the server or pays for Vimeo or a separate CDN service. Infinite Uploads covers storage, video, and CDN bandwidth on one monthly price.
Move a Growing Site Without Rebuilding a Page
The first sync moves your existing Media Library, including any background video already on the server, and rewrites URLs to the CDN. Every Container, Gallery, and Slider keeps pointing at the same files, and Download & Disconnect returns them to local storage if needed.
Every Client Site on One Account
Agencies building on Spectra for a dozen client sites connect all of them to one Infinite Uploads account. Unlimited sites on every plan, one usage dashboard, no separate cloud credentials to hand off when a project wraps.
What Works, Feature by Feature
Feature
What you get
Container block background images
Section and row backgrounds set through the Container block's background type offload and optimize automatically, the same as any other page content image.
Works
Container background video (self-hosted MP4)
A Video background type serves the MP4 from the CDN instead of your origin server, as-is, the same way any self-hosted upload does.
Works
Video Cloud for on-page video
For a video visitors watch, not a background, upload to the Infinite Uploads Video Library and embed it with the Infinite Uploads block. Transcoded for adaptive streaming and played in the customizable player, included on every plan.
Works, Video Cloud
Image Gallery block
Every photo in the gallery is optimized to AVIF and WebP, right-sized, and served from the CDN edge closest to each visitor.
Works
Slider block
Slide images offload and optimize the same as any Media Library upload, and serve from the CDN edge closest to each visitor.
Works
Info Box, Testimonials, Modal, and Popup Builder images
Icons, avatars, and background images used across these blocks offload, optimize, and serve from the CDN like any other Media Library file.
Works
Design Library and starter template imports
The Design Library imports templates through the separate Astra Starter Templates plugin. Demo images land in your Media Library and count toward storage until you delete what the design doesn't use.
Review after import
Spectra's File Generation setting (separate CSS/JS files)
Off by default, Spectra prints CSS and JS inline. Turn it on and Spectra writes real files to wp-content/uploads/uag-plugin. Exclude that folder in Infinite Uploads > Settings, or leave File Generation off.
Exclude uag-plugin folder
WordPress Multisite networks of Spectra sites
Every site in the network offloads to the same account and shares one storage pool.
Works
Up and Running in Three Steps
1. Connect Infinite Uploads
Install the plugin, connect your account, and sync. Existing gallery images, background video, and popup graphics move to the cloud.
2. Upload to the Video Library for Adaptive Streaming
A Container background video plays from the CDN as-is. For on-page video, upload through Media → Video Library and embed with the Infinite Uploads block.
3. Free Up Local Storage
Remove local copies once the sync finishes. Your host keeps the freed space, files stay on the CDN.
Good to Know Before You Switch
Self-hosted video in Spectra counts toward storage and bandwidth, not Video Cloud transcoding minutes. A Container background video or a large gallery of full-resolution photos both add up over a media-heavy site. Size your plan on total storage and check the pricing calculator before a large migration.
Design Library and starter template imports are worth a look before you publish. Spectra's own documentation confirms importing a template through the Astra Starter Templates plugin brings its demo images along with its layout, so a template full of stock photos lands in your Media Library at once.
Turn on File Generation only if you also plan for it. Off by default, Spectra prints CSS and JS inline. Switch it on and those files write to wp-content/uploads/uag-plugin as real files, so exclude that folder in Infinite Uploads > Settings if you offload the whole uploads directory.
How We Tested
- Built a page with an Image Gallery block, a Slider, and a Container background image.
- Added a self-hosted MP4 as a Container background video.
- Set up a Modal, a Popup Builder popup, and a Testimonials block with avatar images.
- Imported a Design Library starter template and checked the Media Library afterward.
- Confirmed gallery images and the background video served from the CDN domain on the published page.
Result: everything worked, no configuration needed.
Frequently Asked Questions
Do the Image Gallery, Slider, and Container background still work?
Yes. Infinite Uploads only changes where the images live. Gallery layouts, Slider transitions, and Container background settings all keep working, and every image serves from the CDN instead of your server.
Can I use a self-hosted Container background video without it stalling?
Yes. The Video background type serves the MP4 from the CDN instead of your own server, as-is. For on-page video, upload to the Video Library and embed with the Infinite Uploads block for adaptive streaming, included on every plan.
What about Modal and Popup Builder background images?
They offload, optimize to AVIF and WebP, and serve from the CDN the same as any other Media Library image. Popup layouts and triggers keep working exactly as configured.
What happens to Design Library and starter template imports?
Their demo images land in your Media Library through the separate Astra Starter Templates plugin and offload the same as any upload, but they count toward storage until you delete what the design doesn't need.
Will Spectra pages load faster?
Yes. Images from the Image Gallery, Slider, Info Box, and Container blocks are converted to AVIF and WebP, right-sized, and served from the nearest CDN edge.
Do Media Folders work inside the block editor's media popup?
Yes. The folder sidebar, sort, and search appear inside the media modal you use to add or swap images and video from within Spectra blocks, not just the main Media Library page.
Can an agency use this across many Spectra client sites?
Yes. Infinite Uploads supports unlimited sites on every plan and WordPress Multisite, so an agency connects every client site to one account with one usage dashboard and one invoice.
What if a gallery image or background video is bigger than the WordPress upload limit?
Add our free Big File Uploads plugin. It lifts the WordPress upload limit without server changes, and Infinite Uploads offloads it from there.
