YouTube Affiliate Partnerships Boost: cut taggable clips with Sume

Affiliate Partnerships Boost does not take a creative from you; it amplifies organic videos that already have your products tagged. So the way Sume helps is upstream: cut your own long product footage into short, standalone clips with video-trim ($0.02 per job) so there is more tagged content for creators and your own channel to publish.

Google's Brandcast 2026 advertiser updates (read 2026-10-04) say the feature "lets brands amplify organic content that their products are already tagged in" and that creators can earn with YouTube Shopping affiliate links. The post gives no rollout date, eligibility rules or creative requirements, so treat it as announced, not as a spec.

What does the announcement say, and what is missing?

Only the first column below comes from Google's page. The second column is what you still need to look up in Google's help center before you plan spend.

How do I cut one product video into several clips?

video-trim takes a source from your workspace's media.sume.com (import an outside file first with POST /v1/media-imports), a start in seconds, and exactly one of end or duration. A cut can run 0.2 to 900 seconds and the source can be up to 1800 seconds. The default precision is exact; the keyframe option is faster but starts on the nearest keyframe.

The script below cuts three 20-second clips from one import. Every request needs an Idempotency-Key header, and sync mode waits up to 30 seconds.

import os, uuid, requests

SRC = os.environ["SUME_SOURCE_URL"]  # a media.sume.com URL
HEADERS = {"Authorization": f"Bearer {os.environ['SUME_API_KEY']}"}

for start in (0, 45, 120):
    r = requests.post(
        "https://api.sume.com/v1/video-trim",
        headers={**HEADERS, "Idempotency-Key": str(uuid.uuid4())},
        json={"video_url": SRC, "start": start, "duration": 20, "mode": "sync"},
        timeout=60,
    )
    print(start, r.status_code, r.json())

What should each clip contain?

Pick moments where the product is on screen and named, because a tag only helps if the viewer can see what it points to. Add burned-in captions with video-captions afterward if the cut starts mid-sentence; that model is $0.20 per job for videos up to 60 seconds.

Keep the rights question separate. Only trim footage you own or are licensed to edit. A creator's published video is theirs, so ask for their approval before cutting it up. The stored post on clipping your own long video into Shorts covers the originality angle, and the one on YouTube Shopping affiliate product videos covers the affiliate side.

Is this worth doing before Boost is live for you?

Probably, if your footage sits unused. Cutting is cheap, and clips that exist can be tagged the day the feature reaches your account. Spend nothing on promotion until Google publishes the eligibility and billing details.
