How to make viral shorts from a YouTube video

The fastest way to turn a long-form YouTube video into a pack of captioned 9:16 shorts — about 3 minutes, no editor, no timeline, no captions to sync. Updated April 2026.

The four-step process

Same flow whether your source is a podcast, an interview, a long YouTube video, or a livestream VOD.

  1. 01

    Paste a YouTube URL or upload a video

    Sign in to AlcheClip, click New Job, and paste any YouTube URL — or drop a video file up to 500MB. The MVP supports source videos up to 15 minutes long. Podcasts, interviews, vlogs, lectures, livestream VODs all work.

  2. 02

    Let AlcheClip transcribe and score moments

    AlcheClip uses OpenAI Whisper for word-level transcription, then scores every spoken segment for hook strength using length, filler-word density, and hook-keyword signals. Non-maximum suppression dedupes overlapping candidates, and the 5–12 strongest moments are selected automatically.

  3. 03

    Wait ~3 minutes for the enhancement pass

    Each clip is cropped to 9:16, upscaled to 1080p with Lanczos, sharpened with an unsharp mask, denoised with hqdn3d, color-graded for mobile viewing (contrast 1.08, saturation 1.12, gamma 0.98), and burned with karaoke-style word-level captions generated from the Whisper timestamps.

  4. 04

    Download the zip of MP4 clips

    AlcheClip delivers each clip as an individual H.264 MP4 plus a single zip. Drop them straight into TikTok, Instagram Reels, or YouTube Shorts — captions are burned into the pixels, so no editing app is required on your audience's side.

Tips for higher-performing shorts

  • Pick sources with strong intros. AlcheClip's hook scoring works best on talking-head content where the speaker frequently sets up their points.
  • Trust the word-level captions. Don't add a second caption track on top in TikTok or Reels — AlcheClip's burned captions are designed to read on mute and already match the retention style top creators use.
  • Post all the candidates. Every job returns 5–12 hook-scored clips. Even the lower-scored ones often outperform — the algorithm doesn't know your audience, your audience does.
  • Stick to one show per account. TikTok and YouTube Shorts both reward niche consistency. Posting all six clips from a podcast episode to one channel beats spreading them.
  • Use AlcheClip's 9:16 1080p directly. Don't re-export through CapCut. The AlcheClip output is already TikTok's preferred container (H.264 + AAC, faststart, CRF 20).

Frequently asked

How long does it take?+

Most 30-minute podcasts finish in 2–4 minutes of wall-clock time. Longer sources or queue load can reach about 10 minutes. Every step of the pipeline streams live via Supabase Realtime so you can watch progress.

Do I need an editor like CapCut or Premiere?+

No. AlcheClip burns word-level captions directly into the video pixels and exports a TikTok-ready 9:16 1080p MP4. Drag the file into the upload form on TikTok, Reels, or YouTube Shorts and you're done.

What's the free way to do this?+

AlcheClip's free tier gives you one full job per month with no credit card. That includes word-level captions, 1080p 9:16 output, and the same enhancement pass as the paid tiers. The fastest free Opus Clips alternative.

Why are AlcheClip's shorts higher quality than Opus Clips' shorts?+

Because the entire pipeline was designed around output fidelity rather than clip count. Lanczos upscaling instead of bilinear, mobile-tuned color grading on every clip, explicit unsharp masking and denoising, and word-level caption rendering at the pixel level. No filter is optional; no clip skips the enhancement pass.
