Parameters

Pass these values through request.options.

Parameter	Type	Required	Default	Allowed / Range	Description
`targets`	enum[]	Optional	—	—	Social output presets to generate. vertical=1080×1920 (9:16 TikTok/Reels/Shorts), portrait=1080×1350 (4:5 feeds), square=1080×1080 (1:1), landscape=1920×1080 (16:9). Multiple values generate multiple MP4 files.
`layout`	enum	Optional	`auto`	auto \| fill \| fit \| blur	How the source fits each target. auto fills when aspect ratios are close and switches to a blurred background for large ratio changes; fill may crop; fit preserves the entire source with padding; blur preserves the entire source over a blurred background.
`cropFocus`	enum	Optional	`center`	center \| top \| bottom \| left \| right	Crop anchor used by fill/auto when cropping is required. This is a fixed framing anchor, not AI subject tracking.
`quality`	enum	Optional	`balanced`	high \| balanced \| small	Encoding quality preset. high favors visual quality, balanced is the default tradeoff, small favors smaller files.
`keepAudio`	boolean	Optional	`true`	—	Keep the original audio track when one is present. false exports silent video.
`width`	integer	Optional	—	2 – 7680	Legacy custom-size output width in pixels. Used only when targets is omitted and either width or height is supplied.
`height`	integer	Optional	—	2 – 4320	Legacy custom-size output height in pixels. Used only when targets is omitted and either width or height is supplied.
`keepAspectRatio`	boolean	Optional	`true`	—	Legacy custom-size behavior. Preserve source aspect ratio inside width/height. Ignored when targets is supplied.
