Shorts From One Long Video

Several vertical Shorts cut from one long video, each with captions.

Pipeline: Basic edit (cut): cuts, captions, looks, speed, split screens, stock, voices and music.
Format: 9:16
Upload: One long video with speech (a podcast, a talk, a stream, a course lesson).

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 [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.

The blanks

[LONG VIDEO]: The file you uploaded, by its name, and how long it is, for example "episode-42.mp4, 58 minutes".
[TOPIC]: What the video is about, in one sentence.
[NUMBER OF CLIPS]: How many separate videos you want out of the footage, for example 3 or 5.
[LENGTH IN SECONDS]: How long the finished video runs, as a number of seconds. Reels and Shorts hold best between 15 and 60.
[CAPTION COLOR]: The color of the highlighted word in the captions, as a name or a hex code like #FFD23F.
[SERIES NAME]: The title the clips share, so you find them together in your videos.

Tips

Ask for the list first. Picking from five candidates costs nothing; rendering five you don't want spends minutes.
A moment that needs the sentence before it to make sense is not a Short. Say "stand-alone" and your AI will drop those.
The transcript is made once per file, so asking for more clips from the same video later costs no new credits.

Teaser for a New YouTube Video

A 30-second teaser that sells your new YouTube video without spoiling it.

Upload: Your finished YouTube video.

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.

One Edit in 9:16 and 16:9

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.

Talking Head With 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.
