Estimated time: 15 minutes What you'll learn: How to take raw AI-generated video clips and audio into a professional NLE, then color grade, composite, mix audio, and export for delivery. Tools used: Adobe Premiere Pro / DaVinci Resolve, Color.io (optional)
Learning Objectives
By the end of this module, you will be able to:
- Import and organize AI-generated clips in Premiere Pro or DaVinci Resolve
- Identify and fix common visual artifacts in AI-generated footage
- Color grade AI footage for cross-tool consistency and professional polish
- Mix layered audio (dialogue, music, SFX, ambient) to broadcast standards
- Export in multiple format specifications for different delivery platforms
Why Post-Production Is Non-Negotiable
AI-generated clips are raw material, not finished products. Even the best AI video output needs post-production for three reasons:
1. Cross-tool consistency. If you used Kling for shot 1 and Veo for shot 2, they'll have different color profiles, contrast levels, and motion characteristics. Color grading unifies them into a cohesive visual language.
2. Pacing and storytelling. AI generates clips of fixed duration. Professional video lives and dies by its editing rhythm — the timing of cuts, the breathing room between moments, the acceleration toward a climax. This is editorial craft, not generation.
3. Polish and detail. Removing AI artifacts, adding transitions, layering audio, inserting text/graphics, and adjusting timing all happen in post. The difference between "AI-generated content" and "a video" is this stage.
Step 1: Import and Organize
Create a project structure in your NLE that mirrors your production bible:
Project: Origin Coffee Commercial
├── 01_Source_Clips/
│ ├── Shot_01_Take_03.mp4 ← Selected best take
│ ├── Shot_02_Take_01.mp4
│ ├── Shot_03_Take_04.mp4
│ └── Shot_04_Take_02.mp4
├── 02_Audio/
│ ├── Music_Piano_30s.wav
│ ├── VO_Begin_With_Better.wav
│ ├── SFX_Coffee_Pour.wav
│ ├── SFX_Birdsong.wav
│ └── AMB_Morning_Kitchen.wav
├── 03_Graphics/
│ ├── Origin_Logo.png
│ ├── End_Card.psd
│ └── Lower_Third.mogrt
├── 04_Reference/
│ ├── Color_Ref_Image.png
│ └── Edit_Reference_Video.mp4
└── 05_Exports/
Sequence settings for AI video:
Most AI video tools output at 24fps. Set your timeline to match. If you need 30fps delivery, import at native 24fps and interpret/conform in the export settings — don't re-interpret the footage to 30fps on import, as this creates motion artifacts.
Recommended sequence settings:
- Resolution: 1920×1080 (or match your highest-res footage)
- Frame rate: 24fps (match source — do NOT mix frame rates)
- Codec: ProRes 422 (timeline) or H.264 (if storage-constrained)
- Color space: Rec. 709 (standard delivery) or Rec. 2020 (HDR)
Step 2: The Rough Cut
Lay out your selected takes in sequence order. This is the "assembly edit" — every shot in order, at full length, no trimming.
Then begin trimming. AI video clips often have usable sections in the middle — the first and last 0.5-1 seconds frequently contain generation artifacts (warping, flickering, or motion settling). Trim these off.
AI-specific editing considerations:
- Trim generation artifacts: The first 0.3-0.5s and last 0.3-0.5s of AI clips often contain startup/settling artifacts. Cut these.
- Use dissolves sparingly: Cross-dissolves can mask minor inconsistencies between shots, but overuse makes the edit feel amateur. Use cuts as your primary transition.
- Speed ramp to unify motion feel: If Kling clips feel "snappier" than Veo clips, slow down Kling footage to 85-90% to match Veo's more deliberate motion quality.
- Freeze frames for holds: If you need a moment to last longer than the generated clip, freeze the last clean frame and hold for 0.5-1s before cutting. This works well at emotional beats.
- Reverse clips for variety: AI clips often play well in reverse, giving you additional shot options without regenerating.
Step 3: Color Grading for Consistency
This is the most important post-production step for multi-tool AI video. Each AI model has a different default color profile:
Color biases by tool:
- Veo 3.1: Slightly cool, high dynamic range, cinematic contrast
- Kling 2.6: Slightly warm, saturated, commercial feel
- Runway: Varies heavily by generation, often stylized
- Sora 2: Neutral to warm, natural contrast
Three-step color grading workflow:
Step A: Normalize. Before applying any creative grade, bring all clips to the same baseline. In DaVinci Resolve, use the Color Match tool or manually adjust lift/gamma/gain to match exposure and white balance across all clips. In Premiere Pro, use Lumetri Color → Basic Correction.
The goal: every clip should have the same brightness, contrast, and white point BEFORE you add style.
Normalization checklist:
□ White balance matched across all clips (check a white/grey element)
□ Exposure levels matched (check histogram — peaks should align)
□ Contrast ratio similar (blacks and whites at similar levels)
□ Skin tones consistent (use vectorscope — skin falls on the warm line)
Step B: Creative grade. Apply your project's color identity. This is where the hex codes from your color palette (Module 2) come back into play.
For the coffee commercial's warm, morning aesthetic:
- Push shadows toward warm amber (not blue)
- Lift midtones slightly for an airy feel
- Desaturate slightly (85-90% saturation) to avoid the "AI hyper-color" look
- Add a subtle warm tint to highlights
Step C: Film look. AI footage can look "too digital" — perfectly clean in a way real video never is. Adding analog texture sells the realism.
Elements to add:
- Film grain: Subtle grain (2-5% intensity) breaks up the digital smoothness. Use built-in grain effects or overlays.
- Subtle vignette: Darkened corners (10-15% intensity) draws focus to center frame.
- Slight halation: A very subtle glow on highlights mimics how light behaves on film.
- Contrast curve: Pull down the top of the RGB curve slightly — this prevents pure whites, giving the image a more filmic ceiling.
Tool recommendation: Color.io — an AI-powered color grading tool that applies analog film emulation. Upload an AI clip, select a film stock emulation (Kodak Portra, Fuji, CineStill), and it applies a physically-accurate grade. Particularly useful for batch-grading multiple AI clips to the same film look.
Step 4: Audio Mixing
Layer your audio tracks following the stack from Module 5. In your timeline, set up dedicated tracks:
Track layout (top to bottom):
V1: Video clips
A1: Dialogue / Voiceover
A2: Sound Effects
A3: Foley
A4: Music
A5: Ambient / Room Tone
Mixing to broadcast standards:
Target levels:
- Dialogue: -6 to -3 dB peak, -12 dB average (LUFS)
- Music: -18 to -12 dB under dialogue, -6 dB solo
- SFX: -12 to -6 dB (peaked to action, not constant)
- Ambient: -24 to -18 dB (barely perceptible, fills silence)
- Overall mix: -14 to -16 LUFS (broadcast) or -12 to -14 LUFS (social)
Transitions between audio elements:
- Music should fade in over 1-2 seconds, not start abruptly
- When dialogue begins, automate music volume down by 6-12 dB
- Ambient/room tone should be present in every scene — it's the "glue" that makes edits feel continuous
- Cross-fade ambient tracks when cutting between locations
Fixing native AI audio issues:
Native AI audio sometimes has artifacts — metallic resonance, unnatural reverb, or volume inconsistencies. Quick fixes:
- EQ out metallic resonance: Narrow notch filter at the problem frequency (often 2-4kHz)
- Add light compression: Even out volume inconsistencies (ratio 2:1, threshold -12dB)
- Replace problem sections: If a 1-second segment of native audio has artifacts, cut it and replace with library audio or room tone
Step 5: Export for Delivery
Different platforms require different specifications. Here are the current optimal export settings:
PLATFORM EXPORT SPECS (March 2026):
YouTube / Website Hero:
- Codec: H.264 or H.265
- Resolution: 3840×2160 (4K) or 1920×1080 (1080p)
- Frame rate: 24fps or 30fps
- Bitrate: 35-68 Mbps (4K) or 16-24 Mbps (1080p)
- Audio: AAC, 320kbps, stereo
- Aspect ratio: 16:9
Instagram Feed:
- Resolution: 1080×1350 (4:5 portrait)
- Frame rate: 30fps
- Duration: up to 60 seconds
- Bitrate: 8-12 Mbps
- Audio: AAC, 128kbps
Instagram Reels / TikTok / YouTube Shorts:
- Resolution: 1080×1920 (9:16 vertical)
- Frame rate: 30fps
- Duration: up to 90 seconds
- Bitrate: 8-12 Mbps
- Audio: AAC, 128kbps
LinkedIn:
- Resolution: 1920×1080 (16:9) or 1080×1080 (1:1)
- Frame rate: 30fps
- Duration: up to 10 minutes
- Bitrate: 8-12 Mbps
Client Delivery (Master):
- Codec: ProRes 422 HQ (Mac) or DNxHR HQ (Windows)
- Resolution: Highest available
- Frame rate: 24fps
- Full quality, no compression artifacts
Multi-format export strategy:
Edit once at the widest aspect ratio (usually 16:9), then create alternate versions by reframing for 4:5, 9:16, and 1:1. Most NLEs have auto-reframe tools. Review every reframed version — auto-reframe can miss the mark on composition-critical shots.
The Complete Pipeline: End-to-End Recap
Here's the full pipeline you've learned across all 6 modules, applied to a real project:
MODULE 1 — UNDERSTAND THE PARADIGM
You know: AI video = Prepare → Generate → Finish (not text-to-video)
MODULE 2 — PREPARE YOUR INGREDIENTS
You've created: Script, character refs, environment refs, keyframes, audio plan
MODULE 3 — ROUTE YOUR SHOTS
You've decided: Shot 1 → Kling, Shot 2 → Veo, Shot 3 → Veo, Shot 4 → Kling
MODULE 4 — GENERATE YOUR CLIPS
You've generated: 3-5 takes per shot, selected the best, iterated on failures
MODULE 5 — PRODUCE YOUR AUDIO
You've created: Dialogue (ElevenLabs), music (Suno), SFX plan, ambient plan
MODULE 6 — FINISH IN POST
You've done: Edit, color grade, audio mix, export for all platforms
Total time for a 30-second commercial: 7-12 hours Total cost: $20-50 in AI tool credits + NLE subscription Traditional equivalent: $10,000-30,000 and 2-4 weeks
That's the professional AI video pipeline. Not magic. Not luck. A structured process that produces consistent, client-ready results.
Practical Exercise
Exercise: Complete Post-Production on Your Generated Clip
Take the clip you generated in Module 4's exercise and:
- Import into Premiere Pro or DaVinci Resolve
- Trim the first and last 0.5 seconds
- Apply a basic color correction (white balance, exposure)
- Apply a simple creative grade (warm or cool shift matching your project's mood)
- Add a subtle film grain overlay
- Layer in a 5-second music bed from Suno (generate one if you haven't)
- Export at 1080p, 24fps, H.264
This doesn't need to be perfect. The goal is to experience the complete pipeline end-to-end — from keyframe to finished, graded, audio-mixed clip.
Key Takeaways
- Post-production is where AI clips become professional video. Raw AI output is raw material — not a finished product.
- Color grading is the most important post step for multi-tool productions. Normalize first (match exposure/white balance), then apply creative grade, then add film texture.
- AI footage benefits from analog imperfections — film grain, vignette, and slight desaturation combat the "too clean" digital look.
- Audio mixing follows the 5-track stack: dialogue, SFX, foley, music, ambient. Each at calibrated levels.
- Export for every platform from a single timeline using reframing — don't regenerate video for different aspect ratios.
