Squarespace 30 minutes of video storage: how many AI clips fit?

A Squarespace site can hold 30 minutes of uploaded video on the free base allowance, which is 1,800 seconds: 225 clips of 8 seconds, 120 of 15 seconds, or 60 of 30 seconds. The current Squarespace website plans raise that to 5 hours on Core, 50 hours on Plus and unlimited on Advanced. Uploads count toward the quota, so the limit is on the total runtime you upload, not on how many files you add.

Squarespace's per-file rules (500 MB for a video block, 60 seconds for a section background) are well covered already, including in Squarespace background video size. This post is about the sitewide pool and how to budget AI clips against it.

How much video storage does each plan include?

Squarespace's Digital Products plan page has a comparison table. The "Upload videos to your site" page says Basic, Core and Plus website plans raise storage by upgrading the plan, while Personal, Business, Commerce Basic and Commerce Advanced sites use a Digital Products plan. The Digital Products page adds that as of July 23, 2026 you can't sign up for a Digital Products plan, and it points to upgrading the website plan instead. The last column below is my arithmetic: quota seconds divided by 8.

What do the per-use limits add?

The same upload page lists the limits for each place a video can go, plus supported types: .mp4, .m4v and .mov. It says Squarespace shows up to 1080p, accepts uploads up to 4K, recommends 16:9, and converts uploads to MP4 at 1.5 MBps for 360p or 3 MBps for 1080p.

How should I budget AI clips against 30 minutes?

Treat runtime as the currency. A product page with 12 loops of 8 seconds spends 96 seconds, about 5% of the Basic pool. Ten such pages spend more than half of it. Three habits keep an AI-clip site under the cap.

First, make the clip as short as the job needs. A background loop does not need 60 seconds: Sume's Auto model defaults to 8 seconds, with 3 to 10 seconds per clip per the Video Router docs, and seedance-2.5 runs 4 to 30 seconds per the Video generation docs. Second, preview on Sume and upload only the keeper to Squarespace, because every uploaded draft counts. Third, cut with Video trim rather than re-generating: it makes a new MP4 from a range for $0.02 per job (the docs say to confirm the live price in GET /v1/catalog).

def clips_that_fit(quota_minutes, clip_seconds):
    return int(quota_minutes * 60 // clip_seconds)

print(clips_that_fit(30, 8))    # 225 on Basic
print(clips_that_fit(300, 8))   # 2250 on Core

What should I ask Sume for?

Ask for one hero loop per page, image-to-video from the page's own product photo, 16:9, 720p and 8 seconds. Submit it to POST /v1/videos as a first_frame entry in frame_images, then poll GET /v1/videos/{jobId} and download from unsigned_urls[0] once it is completed. Use one Idempotency-Key per page so a retry replays the original job instead of making a second clip you would have to throw away.

Squarespace's bitrate and fallback advice are in Squarespace background video blurry and the low-power fallback post. Neither changes the storage math: a clip that plays well still spends its runtime.

What if the quota runs out?

The video blocks page says you can upload up to 30 minutes of high-resolution video for free and that more space needs a plan change. Upgrade the plan or cut runtime: the quota is stated in minutes of video, so shortening clips is what frees space. If you are on a legacy plan with a Digital Products subscription, Squarespace says you can't change that product's plan and must upgrade the website plan instead.
