Prime Big Deal Days: three deal drops a day, one clip, new price text

Amazon says Prime Big Deal Days run October 6 and 7, starting at 12:01 a.m. PDT, with new deals dropping three times a day: midnight, 8 a.m. and 1 p.m. PDT. If your offer changes by drop, your clip's price text changes by drop. You can handle that with one rendered product clip and several caption jobs that burn different text onto it, using the authored cues field of the Sume video captions endpoint.

Why captions, not a new render

The video captions endpoint accepts cues with text, start and end, and when you pass authored cues it skips speech-to-text. That matters for a silent product clip: with no cues, a silent video fails with the caption_no_speech code. With cues, the same silent clip gets overlay copy.

The clean master stays untouched, and each variant is a new job against it. Every accepted standalone caption job is $0.20 for videos up to 60 seconds under the docs' current fixed estimate, so three drops times four products is twelve jobs, or $2.40 at that rate.

A caption job per drop

The sample below sends one job. Run it once per variant with a different text value and a different idempotency key, and keep the returned job ids so you can poll each one.

import json, os, urllib.request

def main():
    key = os.environ["SUME_API_KEY"]
    body = {
        "video_url": "https://media.sume.com/artifacts/example/clean.mp4",
        "style": "punch",
        "cues": [{"text": "Deal drop 2: 25% off today", "start": 0.5, "end": 4.0}],
    }
    req = urllib.request.Request(
        "https://api.sume.com/v1/video-captions",
        data=json.dumps(body).encode(),
        headers={
            "Authorization": f"Bearer {key}",
            "Content-Type": "application/json",
            "Idempotency-Key": "pbdd-drop-2-sku-101",
        },
    )
    with urllib.request.urlopen(req) as resp:
        print(resp.status, resp.read().decode())

main()

Limits

The video must already be a public URL the endpoint can read. Burned-in text cannot be edited afterwards, so keep the clean master. Marketplace rules decide whether price text in a video is allowed on a given placement, and Amazon's page does not say, so check your ad type's creative policy first. A 25% figure in the sample is a placeholder, not a recommendation.
