Use cases
Worked examples on Sume's catalog Formats and endpoints: product video and photography, try-on, app and product ads, logo animation, and more.
Start with Ready-made Formats for product video: the Sume Format catalog

Text to speech add pause: Flux, HeyGen and Gemini markers vs Sume
Deepgram Flux, HeyGen and Gemini TTS each use their own pause marker. Sume TTS has none, so use punctuation, speed, or a declared silence in Timeline.
TikTok AI voiceover label: generic TTS vs a real person's voice

TikTok bans paid political advertising, including paid creator content. Only official election bodies may advertise procedures such as voter registration.

Twitch is rolling out editable clip captions. For a clip file you edit yourself, Sume burns your own cues with text, start and end, no speech-to-text.
Twitch vertical clips: crop an older 16:9 clip to 9:16
Twitch Dual Format makes vertical clips going forward. For a 16:9 clip without one, crop a 9:16 slice with video-filter: width 0.316, height 1.
Walmart main image size: 2200x2200 and Sume's multiples of 16
Walmart wants a 2200x2200 px main image under 5 MB. 2200 is not a multiple of 16, so generate 2208x2208 on Sume's gpt-image-2.5, then resize.

AI ad resizer: one image, several aspect ratios, one API
Sume has no resizer button. Send the same source image to POST /v1/images once per aspect_ratio (1:1, 4:5, 9:16, 16:9) and recompose each ad slot.
Edit a high-resolution photo with AI: edit first, then upscale
Sume image edits return at catalog tiers (512, 1K, 2K, 4K), not your photo's full megapixels. Edit with aspect_ratio auto, then enlarge with Image Upscale 1.0.
Text to speech reading a confirmation code digit by digit
To make TTS read a code one digit at a time on Sume, write the transcript with the digits separated, pin a Sonic id, and listen before you ship it.

Demand Gen 4:5 video 1080x1350: the API has 3:4, not 4:5
