Canonical: https://cut.express/prompts/youtube-video-teaser [Shorts from long videos](https://cut.express/prompts#shorts-from-long-videos) A 30-second teaser that sells your new YouTube video without spoiling it. - **Pipeline**: Basic edit (cut): cuts, captions, looks, speed, split screens, stock, voices and music. - **Format**: 9:16 and 16:9 - **Upload**: Your finished YouTube video. ## The prompt Type your own words into the fields: the [BLANKS] fill in as you go. Copy it and send it to Claude or ChatGPT with Cut Express connected. Prompt ``` I uploaded my new YouTube video, "[VIDEO TITLE]". Make a [LENGTH IN SECONDS]-second teaser for it. Inspect it with a transcript and moments first. - Open on the most surprising line or image in the video, then 4 to 6 fast cuts of the best moments, never the ending: [WHAT NOT TO SPOIL]. - A text at the top for the first 2 seconds: "[HOOK LINE]", white with a black stroke. - Captions from the speech, pop preset, highlight [CAPTION COLOR]. - End card for 2 seconds: "Full video on my channel" over a dark frame of the video. - [MUSIC] under the voices, ducked when anyone speaks. Render it in 9:16 first. Then render the same timeline again as 16:9 for the community tab, as the next version. ``` ## The blanks - **[VIDEO TITLE]**: The title of the long video, as it is on YouTube. - **[LENGTH IN SECONDS]**: How long the finished video runs, as a number of seconds. Reels and Shorts hold best between 15 and 60. - **[WHAT NOT TO SPOIL]**: The result, the reveal or the answer the teaser must keep hidden. - **[HOOK LINE]**: The first words on screen, the reason to keep watching, in under ten words. - **[CAPTION COLOR]**: The color of the highlighted word in the captions, as a name or a hex code like #FFD23F. - **[MUSIC]**: A track you uploaded (say its file name), or a mood and genre for the stock music search, like "upbeat lo-fi" or "cinematic, builds slowly". ## Tips - Name what not to spoil. Otherwise the strongest moment is often the ending. - The 16:9 version is a new version of the same video, so every note you gave the first one carries over. New to prompting video?

Upload: One long video with speech (a podcast, a talk, a stream, a course lesson). ``` I uploaded [LONG VIDEO], about [TOPIC]. Inspect it with moments and a transcript, then find the [NUMBER OF CLIPS] strongest moments that make sense on their own, each about [LENGTH IN SECONDS] seconds. Before you render, list them for me: the in and out times, the first line said and why it works as a hook. Wait for my pick. For each one I pick: - Start on the hook line, no warm-up. Cut the silences and the false starts on the speech. - 9:16, cover crop kept on the speaker's face. A slow punch-in on the key sentence. - Captions from the speech: bold preset, 3 words per line, the key word in [CAPTION COLOR], bottom third. - Clean the voice (denoise and enhance). No music unless I ask. Render each as its own video titled "[SERIES NAME] 1", "2", and so on. ``` [Fill in](https://cut.express/prompts/shorts-from-a-long-video#fill) [Tips](https://cut.express/prompts/shorts-from-a-long-video) Basic edit9:16 and 16:9 ### [One Edit in 9:16 and 16:9](https://cut.express/prompts/one-edit-two-formats) The same edit as a vertical Reel and a horizontal YouTube cut. Upload: The clips for the edit, shot horizontally or vertically. ``` Make a [LENGTH IN SECONDS]-second edit about [TOPIC] from the clips I uploaded, for [PLATFORM]. Look at the contact sheets before you cut. Start in 9:16: cover crop with the subject kept in frame on every scene (set the focus), hook first, cuts on the action, [LOOK] look, captions from the speech in [CAPTION COLOR]. Show me the timeline before you render. When v1 is done, render the same timeline again as 16:9 for YouTube: re-check each scene's focus, use fit blur where a vertical clip would crop too much, and move the captions so they never sit on a face. ``` [Fill in](https://cut.express/prompts/one-edit-two-formats#fill) [Tips](https://cut.express/prompts/one-edit-two-formats) Basic edit9:16 ### [Talking Head With Jump Cuts](https://cut.express/prompts/talking-head-jump-cuts) A tight talking-head video with the silences cut, punch-ins and captions. Upload: One or more takes of you talking to the camera. ``` I recorded a talking-head video about [TOPIC]. Inspect it with a transcript and use the speech cuts. - Keep only the best take of each sentence and cut every silence and "um". The finished video is about [LENGTH IN SECONDS] seconds. - Start on "[HOOK LINE]" even if I said it later. - A punch-in zoom (about 1.2x) every 2 or 3 cuts, on the words that matter, so it never looks like one static shot. - Captions: bold preset, upper case, 2 to 3 words per line, highlight [CAPTION COLOR], just under the middle of the frame. - Clean my voice: denoise 40 and enhance. [LOOK] look, a little sharpening. Show me the timeline (each kept line with its time) before you render. ``` [Fill in](https://cut.express/prompts/talking-head-jump-cuts#fill) [Tips](https://cut.express/prompts/talking-head-jump-cuts)
