How to Turn Long YouTube Videos into Viral Clips with AI

AutoFeed's YouTube Clips runs a fully automated pipeline whenever you submit a URL:

• Download the source video using yt-dlp
• Transcribe the audio with word-level timestamps using Whisper
• Analyze the full transcript with AI (Gemini 2.5 Flash) to identify the most viral moments
• Cut each moment with FFmpeg using lossless stream copy
• Re-render each clip with burned-in captions, an optional 5-second hook overlay, and your chosen format (9:16, 16:9, or 1:1)
• Score every clip on Hook, Flow, Value, and Trend so you know which ones to actually post

The whole pipeline runs in the background — most jobs finish in 3-8 minutes depending on source length.

Head to Create → YouTube Clips in your dashboard. Paste a YouTube URL — anything from a 15-minute podcast highlight to a full 60-minute interview will work. AutoFeed will fetch the video's title and thumbnail so you can confirm you've got the right one before paying credits.

Once the URL is valid, the Clip Settings section unlocks. It contains three collapsible subsections:

• Clip Settings — number of clips (1-8 slider), clip duration (under 30s, 30-45s, 45-60s, 60-90s), and the auto-generate hook toggle
• Captions — caption style picker, caption size (Small/Medium/Large), and position (Top/Center/Bottom)
• Video Output — format (9:16 vertical for TikTok/Reels/Shorts, 16:9 horizontal for regular YouTube, 1:1 square) and video fit (Cover crops to fill, Contain letterboxes)

When you're ready, scroll to the Generate section and click Generate. AutoFeed immediately navigates you to the job detail page where you can watch the clips appear in real time as they finish — most jobs take 3-8 minutes.

Each clip comes back with four scores out of 100 plus a letter grade from A+ down to D:

• Hook (0-100): How attention-grabbing the first 3 seconds are
• Flow (0-100): How well the clip stands alone as a self-contained thought
• Value (0-100): How insightful, useful, or entertaining the content is
• Trend (0-100): How well the clip aligns with current short-form patterns

Click any clip to open the detail dialog and see the full transcript, individual scores, and AI feedback explaining each rating. Don't feel obligated to post every clip — posting only your A and A+ clips trains the algorithm that your account produces high-engagement content, which lifts everything you post going forward.

Not every long-form video makes good clip fodder. The ideal source has:

• Multiple distinct ideas or stories — podcasts and interviews are perfect, music videos are not
• Strong audio narrative — talking-head content with clear takes
• 15-60 minutes of runtime — shorter videos may not have enough viral moments, longer videos get expensive fast (per-minute pricing)
• A confident speaker — clean, clear delivery without long pauses or rambling

Avoid: gameplay footage with no commentary, music videos, ASMR, slow tutorials with lots of dead air. AutoFeed will still produce clips from these, but the virality scores will reflect the underlying material.

Two settings have an outsized impact on watch-through rate:

Always leave the hook overlay on. The 3-second white pill at the top of each clip gives viewers an instant reason to keep watching. AutoFeed auto-generates the hook text from the AI analysis — it's tuned to feel natural, not clickbaity.

Pick a punchy caption style. Center captions perform extremely well on TikTok because the algorithm tends to keep them in the safe zone away from UI overlays. Use Medium or Large size for accessibility — the audience scrolling at 2x speed needs to read it without effort.

Once your clips are rendered, you have three options for each one:

• Download the rendered MP4 and post manually
• Upload to Socials to push to YouTube or TikTok right now
• Schedule to pick a future date and time — AutoFeed will post it for you and you can manage it from the Calendar page

The scheduling option is where the real time savings compound. Generate 6 clips in one session, schedule them across the next 5-7 days, and you've automated a week of content in 10 minutes of work.

YouTube Clips uses a transparent three-part pricing formula:

• Base cost: 1,000 credits per job
• Per minute of source video: 100 credits
• Per clip generated: 500 credits

Example: A 30-minute video with 5 clips = 1,000 + 3,000 + 2,500 = 6,500 credits.

When you submit a job, AutoFeed charges based on a 30-minute estimate. Once the real video is downloaded, the cost is automatically adjusted — you get a refund if the video is shorter, or get charged the difference if it's longer. If a job fails for any reason, all credits charged are automatically refunded.

YouTube Clips is available on Pro and Ultimate plans.
