Black Friday / Flash Sale Countdown
A 19-second vertical flash-sale spot (1080x1920, 9:16) cut to the beat of its own 126 BPM track. Five scenes hit on the music: the sale name slams in, the discount drops with a burst of debris, the product photo gets a camera punch and a LIMITED STOCK sticker, a clock dial frames the deadline, and the promo code and SHOP NOW button land with confetti. Yellow and black grounds flip on the beat, a few medium sound effects mark the big moments, and the text holds still once it lands, so every value stays readable. A header carries the sale name and store name through every scene. Twelve fields swap per render: sale_name, store_name, discount_value, discount_scope, deadline_label, time_remaining, urgency_line, promo_code, cta_label, cta_detail, terms_note and product_image, so Friday's offer, Saturday's deadline and Sunday's last chance come from one template.

Frequently asked questions
How do I customize the Black Friday / Flash Sale Countdown template?
Open the template in the Renderly editor and replace its 12 customizable fields (such as Sale Name) with your own text, images, or video. Every change previews instantly before you render.
How much does it cost to render this template?
Rendering is credit-based - 1 credit equals 1 minute of 1080p video, billed by the second. You only pay when you export, and credits never expire on the pay-as-you-go plan.
Can I generate this video at scale via the API?
Yes. POST this template's ID and a replacements object to /api/v1/renders - one call per row of data, 12 fields swappable per video. Send the same body to /api/v1/previews first to check it for free. No-code integrations like Zapier work the same way.

Product Reel - Black Friday
A 15-second vertical Black Friday product reel in a premium, after-dark style, made for Instagram Reels, TikTok and YouTube Shorts. 1080x1920, 30fps, four scenes on a sleek, minimal deep-house bed: a fine line of light draws across a black screen and the words Black Friday rise from it in brushed silver serif type, the line opens into a lit card where the product appears on a glossy black floor, the photos step through a dark carousel above the product title, and the offer ends on the silver wordmark, a price panel with the old price struck through in red and an address bar with the store URL and a Shop now button. Deep black, warm white Geist type, Instrument Serif for the wordmark and one sharp red accent. Eight fields swap per render: product_title (up to about 60 characters, 1 to 3 lines), price and was_price (preformatted, up to 12 characters each), store_name (up to 24 characters), store_url (up to 30 characters), and product_image_1, product_image_2 and product_image_3. Every photo is contain-fit and blended onto a warm white card, so a white-background packshot or a transparent PNG reads as cut out and is never cropped, and a lifestyle photo keeps its own background. One photo can fill all three slots. Fill every text field: an empty value renders placeholder text. In the free Shopify product video tool the old price disappears when a product has no compare-at price. Attribution appears once, small, on the closing seconds.
Product Reel - Minimal
A 15-second vertical product reel in a quiet, premium style, made for Instagram Reels, TikTok and YouTube Shorts. 1080x1920, 30fps, five scenes on a warm, minimal electronic bed: the product rises from behind a fine horizon line under the store name, moves into an editorial frame with the product title in a light sans, opens into a three-card gallery, fills the frame under "Now available.", and settles above the price, the old price struck through and an address bar with the store URL. Warm paper and stone neutrals, one muted clay accent, Geist type in two weights, and smooth shared-element moves instead of wipes. Eight fields swap per render: product_title (up to about 60 characters, 1 to 3 lines), price and was_price (preformatted, up to 12 characters each), store_name (up to 24 characters), store_url (up to 30 characters), and product_image_1, product_image_2 and product_image_3. Every photo is contain-fit and blended onto a white surface, so a white-background packshot or a transparent PNG reads as cut out and is never cropped, and a lifestyle photo keeps its own background. One photo can fill all three slots. Fill every text field: an empty value renders placeholder text. In the free Shopify product video tool the old price disappears when a product has no compare-at price. Attribution appears once, small, on the closing seconds.
Product Reel - Glass
A 15-second vertical product reel in a soft, modern app style, made for Instagram Reels, TikTok and YouTube Shorts. 1080x1920, 30fps, five scenes on a bright, soft electronic bed: a frosted notification from the store lands on a drifting pastel gradient and grows into the product card, the product title sits on a frosted panel, three photo cards fan out with a gentle 3D turn, and the offer ends on a price card with the old price struck through and an address bar with the store URL and a Shop now button. Frosted cards with large rounded corners, soft layered shadows, Geist type and one periwinkle accent. Eight fields swap per render: product_title (up to about 60 characters, 1 to 3 lines), price and was_price (preformatted, up to 12 characters each), store_name (up to 24 characters), store_url (up to 30 characters), and product_image_1, product_image_2 and product_image_3.
