THE 3-STEP AI VIDEO WORKFLOW

Record → AI edits → Post. That's it. Here's the detail.

STEP 1: RECORD SOMETHING WORTH EDITING

AI can't fix a bad video, but it can make a good one great. What you need:

  • 5-30 minutes of raw footage (talking head, screen record, or anything)
  • Decent audio (this matters more than video quality)
  • Your phone, a webcam, or a camera — doesn't matter which

If you're recording yourself talking: speak naturally, pause when you mess up, and keep going. AI will cut the mistakes.

STEP 2: AI EDITING TOOLS

FOR TALKING HEAD VIDEOS — DESCRIPT Record your video → Upload to Descript (descript.com) → It transcribes your video automatically.

Then:

  • Remove filler words (um, uh, like) with one click — removes them from video and audio
  • Delete words from the transcript → the clip disappears from the video
  • Remove silences → tighter, faster video automatically
  • Fix mispronounced words with Overdub (AI voice correction)
  • Add captions automatically

Result: Professional, tight video without any manual timeline editing.

FOR SHORT-FORM CLIPS — OPUS CLIP Upload a long video or paste a YouTube link → Opus Clip finds the best moments and creates short clips → Auto-adds captions → Download and post.

Best for: Turning podcasts, webinars, or long videos into TikTok/Reels/Shorts content.

FOR MOBILE CONTENT — CAPTIONS APP Record on your phone → Open Captions → AI adds animated captions, removes silences, suggests B-roll. Export and post.

FOR THUMBNAIL CREATION — MIDJOURNEY OR CANVA AI "Generate a YouTube thumbnail background for a video about [TOPIC]. Bold colours, cinematic, no text. --ar 16:9"

Then add your text and face photo in Canva.

STEP 3: AI-GENERATED B-ROLL

Don't have footage of what you're talking about? Use AI:

  • Runway ML or Pika Labs: text-to-video for short illustrative clips
  • Storyblocks or Pexels: free stock footage, found faster with AI search
  • CapCut: has built-in B-roll suggestions that match your script

CAPTIONS — DO THEM EVERY TIME

85% of social media videos are watched without sound. Captions are not optional.

Tools:

  • Captions app (mobile) — best for creators
  • Descript (desktop) — best for long-form
  • CapCut (free) — good built-in caption tool
  • Rev.com — if you want human-verified accuracy

AUTO-GENERATE A VIDEO SCRIPT WITH AI

Before recording, use ChatGPT or Claude: "Write a [LENGTH] video script about [TOPIC] for [PLATFORM]. Target audience: [WHO]. Include: strong hook (first 5 seconds), 3 main points with examples, and a CTA. Conversational tone — write it how someone would actually say it, not how they'd write it."
