Why TikTok advertisers need URL-to-video
TikTok rewards fresh creative and native vertical video. Most stores still upload repurposed 16:9 clips or static images — both underperform.
An AI video ad generator for TikTok Ads should:
- Accept a product URL (not a blank prompt)
- Generate a 3-second hook that stops the scroll
- Export 9:16 with voiceover + subtitles
- Let you batch angles per SKU without a video editor
SeedAds checks all four.
