TikTok Automotive Ads specs: 4:3 800x600 images, 5 to 60 s video

TikTok Ads Help lists Automotive Ads product images at 4:3, preferred 800x600 and minimum 450x450, and video at 5 to 60 seconds (21 to 34 recommended), up to 500 MB and at least 516 kbps. A video end card is 800x600. Sume Timeline accepts even output sizes from 256 to 2160, so 800x600 is a valid render size.

What the page lists

The carousel final slide has three listed sizes.

Render an 800x600 end card clip

Timeline 1.0 turns a Sume-hosted still into a held clip. Set output to 800 by 600, fit to cover to fill without bars, and an audio spine, or silence, for the declared duration. A render costs $0.10 per output minute, rounded up, and the free plan endpoint checks the request first.

Before you rely on it

The page says end card; check the exact type (image or video) in your TikTok Ads Manager before choosing a clip. For an image at 800x600, crop a still with video frames or video filter crop using fractions of the source: a 4:3 window of a 16:9 frame is 0.75 of the width at full height.

If the source is 16:9, that is width: 0.75, height: 1, and x of 0.125 centres it.
