Go to Post Studio in the sidebar, drag and drop your video file, select your target platforms, and click Publish. Supported formats: MP4, MOV, WebM, AVI, MKV (max 800 MB).
Cover generation happens inside Post Studio — there is no separate AI Cover tool. Upload your video and the AI picks the strongest frame; you can also supply your own photo or a text description instead. You get a plain cover and a version with an AI-written title and subtitle, each in vertical and horizontal sizes, and finished covers are saved under My Covers.
AI Soundtrack analyzes your video's mood and rhythm, then recommends background tracks that match. You can preview and select the track before exporting.
To protect your privacy and reduce storage costs, uploaded files and generated assets are automatically purged after 24 hours. Download your results before then.
Each AI operation (cover generation, music recommendation, video publish) costs a fixed number of Spark credits. You can view your balance and purchase more Spark credits on the Pricing page.
Currently TikTok, Instagram Reels, YouTube Shorts, and Facebook. More platforms are coming soon.
