YouTube RSS automation: auto-clip new uploads into shorts

YouTube channel RSS feeds wired into Whisper transcription + AI clipping + auto-publishing on TikTok, Reels, and Shorts.

The direct answer

YouTube channels emit RSS feeds at the hidden URL youtube.com/feeds/videos.xml?channel_id=CHANNEL_ID. Wiring that into an automation pipeline lets new uploads trigger automatic clipping, captioning, reframing, and cross-posting to TikTok, Reels, and YouTube Shorts within hours of the original upload. Most useful for podcast hosts who already publish to YouTube and want to amplify across short-form platforms without operator work.

YouTube has had RSS feeds since 2006 and most marketers do not know it. The feed is hidden, undocumented in the main YouTube docs, but stable and standardized. It lists new uploads with title, description, and the video URL — everything you need to wire it into a content automation pipeline.

This is the complete 2026 setup for YouTube-driven content automation, including the feed URL pattern, the clipping workflow, and the platform-specific reformatting rules.

Finding your channel RSS feed

YouTube channel RSS feeds are at:

  • For channels with a custom URL: youtube.com/feeds/videos.xml?user=USERNAME
  • For channels with a UCxxx ID: youtube.com/feeds/videos.xml?channel_id=UCxxx (preferred — stable)
  • Find your channel ID at studio.youtube.com → Settings → Channel → Advanced Settings.

The auto-clip workflow

  1. Kompozy polls the YouTube RSS feed every 15 minutes.
  2. When a new upload is detected, Kompozy fetches the video metadata.
  3. Downloads the audio track via yt-dlp.
  4. Runs Whisper transcription on the audio.
  5. Extracts 4-8 candidate clips (high-energy moments, hook detection, applause markers).
  6. Reframes each clip to 9:16 with subject tracking (face detection + center-cropping).
  7. Burns in word-level captions per the Persona Brief's caption style.
  8. Rewrites the hook per platform (TikTok hook differs from LinkedIn hook).
  9. Publishes to TikTok, Reels, YouTube Shorts, Threads with platform-native scheduling cadences.

Platform-specific reformatting rules

  • TikTok: 9:16, 15-60 seconds optimal, hook in first 3 seconds, hashtags in caption.
  • Reels: 9:16, 15-90 seconds, hook in first 3 seconds, hashtags in caption.
  • YouTube Shorts: 9:16, 15-60 seconds, hashtags in title and description, no hashtags in voiceover.
  • Threads: 9:16, 15-30 seconds, terser hook, fewer hashtags.
  • LinkedIn (native video): 9:16 works but 1:1 outperforms; 30-90 seconds, slower pacing, contextual intro.

Cadence and timing rules

Do not publish all 4-8 clips simultaneously — that cannibalizes algorithmic reach across platforms. The default Kompozy schedule:

  • Day 0 (upload day): 1 clip on TikTok, 1 on Reels, 1 on Shorts.
  • Day 1: 1 clip on TikTok, 1 on Reels.
  • Day 2-4: 1 clip per day across rotating platforms.
  • Day 5+: backfill remaining clips at 1/day until exhausted.

Spreading 4-8 clips across 4-7 days extracts 2-3x the engagement vs same-day blast.

Caveats and edge cases

  • YouTube Shorts has a 60-second hard cap. Auto-clipping respects this; longer clips fail validation.
  • Music in source videos. If your YouTube video has copyrighted music, the clips inherit the copyright issue. Strip the music track before clipping, or use original audio only.
  • Live streams. RSS captures live streams as new entries, but the workflow only fires when the stream ends and the VOD is available.
  • Unlisted uploads. If you upload as unlisted while editing, the RSS fires on the unlisted publish. Set the workflow to wait for "public" status before generating.

Frequently asked questions

How do I find my YouTube channel RSS feed URL?

youtube.com/feeds/videos.xml?channel_id=UCxxx where UCxxx is your channel ID. Find your channel ID at studio.youtube.com under Settings → Channel → Advanced Settings.

How long does the auto-clip workflow take per video?

For a 20-minute video: 5-10 minutes of compute (transcription + clipping + reframing) + scheduled publishing across 5-7 days for the 4-8 generated clips.

Will YouTube penalize me for cross-posting clips to TikTok?

No — both platforms accept cross-platform content. What they penalize is identical reuploads with watermarks visible. Kompozy strips watermarks and applies platform-native captions, so the clips look native to each platform.

Can I exclude specific videos from auto-clipping?

Yes — Kompozy supports keyword exclusions (e.g., "DO NOT CLIP" in the YouTube video description), publish-status gates (auto-clip only on public uploads), and per-video manual overrides.

What about live stream archives?

Live streams trigger the workflow once the VOD is publicly available (typically 30-60 minutes after stream ends). Real-time clipping during a live stream is a separate feature, not RSS-driven.

Can I auto-clip private or members-only videos?

Members-only videos are not in the public RSS feed and cannot be auto-clipped. Private videos are accessible only to the channel owner and require manual upload to Kompozy.
