You’ve generated a clean AI glass fruit cutting clip (Part 1). But raw output isn’t enough to go viral — platforms like Shorts, TikTok, and Reels reward clips that look polished, sound satisfying, and loop seamlessly. Without post-production, even the best AI render feels unfinished and loses retention. This Part 2 guide explains how to elevate your video with ASMR sound, loop tricks, and color/light polish. We’ll cover two paths—Beginner (CapCut) and Pro (DaVinci Resolve/Premiere)—plus export presets, licensing notes, and troubleshooting.

Sound design: the satisfying layer
Core stack (3 layers)
- Knife whoosh – airy swipe starting ~100 ms before contact.
- Glass crack – tight mid-freq hit exactly on the slice frame.
- Shard tinkle – light chimes trailing 0.2–0.4 s after the crack.
Beginner (CapCut)
- Open Audio > Sound effects and search: “whoosh”, “glass crack”, “tinkle”.
- Place whoosh slightly before the blade hits; align crack on the exact impact frame; extend tinkle just after.
- Levels: set each SFX around −12 to −8 dB. If it clips, add Limiter on Master at −1 dB.
Pro (DaVinci Resolve / Premiere)
- Resolve Fairlight: add EQ to the crack track—boost 3–6 kHz (+3~5 dB), high-pass @ 120 Hz; optional stereo widen (10–20%).
- Premiere: in Essential Sound, tag as Sound Effect, apply Clarity and Limiter (Ceiling −1 dB).
- Target loudness: mix bus around −12 LUFS (SFX stems −14 LUFS each → bus −12 LUFS).

Quick EQ recipe (crack SFX) - High-pass: 120 Hz - Presence: +3 dB @ 4.5 kHz (Q=1.2) - Air: +2 dB @ 10 kHz shelf - Limiter: ceiling -1.0 dB
Looping (Shorts/TikTok) – beginner & pro
Goal: viewers can’t tell where it starts or ends. Watch time ↑
Beginner (CapCut)
- Place the cut point after the slice settles (clean frame).
- Freeze Frame last ~6 frames → duplicate at the end.
- Video: add a 2–3 frame cross-dissolve from end → start.
- Audio: add 100–200 ms crossfade on the tinkle tail.
- Loop preview: if you “feel the seam”, shorten fades.
Pro (Resolve/Premiere)
- Resolve: last 6–8 frames on a still (Retime > Freeze), Cross Dissolve 2–3 frames; audio Constant Power 100–200 ms.
- Premiere: duplicate first 3 frames at the end and crossfade Exponential Fade.
- Alternative: reverse the clip for a “knife resets” illusion (works only if the subject stays steady).
Color grading & light polish
Beginner (CapCut)
- Adjust → Temperature −5~−10 (cooler), Contrast +10~+15, Highlights −10.
- Sharpen +5~+8 → edges look crisper.
- Optional: Auto Enhance (reduce if noisy).
Pro (Resolve/Premiere)
- Resolve (Color): cool Gain wheel slightly; soft-clip whites; Midtone detail +5.
- Apply an ice/glass LUT; reduce Saturation −10~−20% to avoid plastic look.
- Premiere Lumetri: Temp −10, Contrast +15, gentle S-curve, Vibrance −5.
Minimal “Crystal” look (Resolve) - Lift: -0.02 - Gamma: +0.01 - Gain: -0.03 (Blue bias +2) - Saturation: -0.12 - Midtone Detail: +5
Editing tools: quick comparison
Tool | Best for | Pros | Watch-outs |
---|---|---|---|
CapCut | Beginner, mobile/quick | Free, built-in SFX, fast export | Limited meters (no LUFS), fewer pro FX |
DaVinci Resolve | Color/audio precision | Free version powerful, pro meters | Learning curve |
Premiere Pro | Batch & pro pipeline | Industry standard, AE integration | Paid, heavier on resources |
VN Editor | Simple mobile loops | Free, lightweight | Limited grading/audio |
10-minute workflow (step-by-step)
- Import the AI video.
- Add whoosh, crack, tinkle SFX.
- Align crack peak with the slice frame; preview loop.
- Color: cool tones, add contrast, tame highlights; light sharpen.
- Create loop: freeze last 6 frames → crossfade 2–3 frames → audio fade 100–200 ms.
- Export: 1080×1920, 24–30 fps, H.264 12–15 Mbps.
- Phone test: check loop; tweak if seam visible.
Troubleshooting
Problem | Fix |
---|---|
Audio feels late | Shift crack earlier; pre-delay whoosh 60–120 ms. |
Loop seam visible | Pick a cleaner end frame; shorten video dissolve; extend audio fade. |
Highlights blown | Lower gain; apply soft-clip; reduce exposure. |
SFX distorts | Limiter −1 dB; reduce track −2 dB; check overlaps. |
Looks plasticky | Cool tones, reduce saturation 10–20%, add specular contrast. |
Export settings by platform
Platform | Resolution | Codec | Bitrate | FPS | Loop duration | Notes |
---|---|---|---|---|---|---|
YouTube Shorts | 1080×1920 | H.264 (MP4) | 12–15 Mbps | 30 | 4–6s | Fast start; test loop on mobile |
TikTok | 1080×1920 | HEVC (H.265) or H.264 | 15 Mbps | 30 | 4–6s | HEVC reduces file size if supported |
Instagram Reels | 1080×1920 | H.264 (MP4) | 10–14 Mbps | 30 | 4–6s | Short punchy loops perform better |
Always preview on a phone before posting—algorithms favor clips that loop smoothly without stutter.
SFX licensing & safety
- Use licensed SFX only: CC0 (Pixabay) is safest; Freesound requires checking terms.
- Avoid logos/watermarks in video/audio.
- Disclose AI content in captions if required.
Extra tips for virality
- Publish as a mini-series: apple → lemon → grapes (same framing).
- Minimal captions: “Glass Apple ASMR 🍎✨” (avoid heavy text).
- Pin the best performer; link siblings in comments to chain views.
- A/B test color: cooler “crystal” vs warmer “fruit”.
- Try pure ASMR (no music) vs subtle ambient bed; check retention.
