Yes. A title and the promise behind it are enough to shape directions; a key frame or portrait gives the hero subject something real to build on. ### Can you use a frame from my video? Export the frame or take a screenshot and share it, and it becomes the hero subject the thumbnail is built around. ### Can I put text in the image? Yes. Give the exact wording and where it should sit, and the layout is built around it, or keep a clear headline area and set the title yourself. ### Can I keep one look across a series? Yes. The direction you use becomes a channel rule covering subject placement, contrast, and text area, for later episodes to follow. ## Related Skills - [Zhongcao Beauty Note Maker](https://www.beatra.cn/en/skills/zhongcao-beauty-note-maker): Optionally read similar notes and top comments, then get five titles, a body, a four-slide 3:4 plan, cover text, and hashtags. - [Zhongcao Carousel Maker](https://www.beatra.cn/en/skills/zhongcao-carousel-maker): Optionally read same-topic notes and comments, then turn an outline or photos into an ordered 3:4 carousel. - [Zhongcao Cover Maker](https://www.beatra.cn/en/skills/zhongcao-cover-maker): Create vertical 3:4 REDnote covers with clean backgrounds, bold focal composition, and text-safe areas—ready for beauty, food, fashion, and lifestyle notes. - [Zhongcao Food Note Maker](https://www.beatra.cn/en/skills/zhongcao-food-note-maker): Optionally read same-topic notes and top comments first, then create a vertical 3:4 cover, dish close-up, table atmosphere, and detail image.
