피파 한 줄 정리: Video 워크플로우 = pre-prod (shot list) + gen (variant per shot) + post (편집·grade·sound·transition). Single-prompt로 30초 만들려는 건 가장 흔한 trap.
Making a video with AI is like cooking a meal course by course, not pouring everything into one pot. You generate individual short clips (your ingredients), then edit them together (your cooking), add sound design (your seasoning), and control pacing (your plating). Trying to generate a complete polished video in one prompt is like expecting a single button press to produce a finished dinner.
The Clip-First Philosophy
Current video models generate 5–60 second clips at best. Even at the maximum, that's not enough for most content. The professional approach treats each generation as one shot in a sequence — exactly how live-action filmmakers work. Nobody films a movie in one continuous take (well, almost nobody).
Step-by-Step Video Production
PRE-PRODUCTION
┌────────────────────────────────────────┐
│ 1. Write shot list (5-15 shots) │
│ 2. Define visual style + color palette │
│ 3. Choose music/pacing reference │
│ 4. Set duration targets per shot │
└───────────────────┬────────────────────┘
▼
GENERATION
┌────────────────────────────────────────┐
│ 5. Generate each shot as separate clip │
│ 6. Generate 3-5 variants per shot │
│ 7. Select best take for each shot │
│ 8. Note any clips needing regeneration │
└───────────────────┬────────────────────┘
▼
POST-PRODUCTION
┌────────────────────────────────────────┐
│ 9. Import clips into video editor │
│ 10. Trim, arrange, and time to music │
│ 11. Color grade for consistency │
│ 12. Add sound design + voice │
│ 13. Add transitions (use sparingly) │
│ 14. Export and review at full speed │

Motion Prompting for Individual Shots
Each clip prompt should specify three things clearly:
- Subject action — What the subject does ("slowly turns toward camera," "reaches for the cup")
- Camera movement — How the camera behaves ("static lock-off," "slow dolly forward," "handheld with slight sway")
- Temporal arc — What changes over the clip's duration ("morning light gradually intensifies," "expression shifts from neutral to smile")
"A woman walking through a forest, beautiful, cinematic"
"Medium tracking shot following a woman walking left to right through a sun-dappled birch forest, camera at eye level, steady lateral dolly, her hand trails along tree trunks, dappled light shifts across her face, 5 seconds"
Sound Design Layers
Video without sound feels 50% finished. Four layers of audio bring AI video to life:
- Ambient sound — Room tone, nature sounds, city atmosphere. Subtle but essential for immersion.
- Music — Sets emotional tone and pacing. Choose or generate music before editing so you cut to the rhythm.
- Sound effects — Footsteps, door creaks, rustling. These ground the visual in a physical world.
- Voice — Narration, dialogue, or reaction sounds. Use ElevenLabs or native audio models depending on quality needs.
Color Consistency Across Clips
Different generations will have different color temperatures, contrast levels, and saturation. In post-production, apply a single color grade (LUT) across all clips. This is the single most impactful step for making separate AI clips look like they belong in the same video.
- Generate individual short clips, not complete videos. Edit them together like a filmmaker.
- Each clip prompt should specify subject action, camera movement, and temporal arc.
- Sound design is not optional — it's what makes AI video feel professional.
- Unified color grading in post-production is the #1 trick for visual consistency across clips.
