- Recommendation: Master at least one primary tool + be familiar with CapCut (its AI features are too useful to ignore)
- Extreme wide / establishing shot: Sets the environment and spatial context; commonly used as the opening "establishing shot"
- Full shot: Shows full body and environment; ideal for fashion, dance, and sports content
- Medium shot: From knees up; the most common narrative shot; suits dialogue, explainers, and daily vlogs
- Close-up: Chest and above; emphasizes facial expression and emotion; ideal for talking-head, product seeding, and emotional content
- Extreme close-up: Facial details or product details; creates visual impact; ideal for food, beauty, and product showcase
- Short-video golden rule: A visual hook must appear within 3 seconds - typically a close-up or extreme close-up opening
- Push in: Far to near; guides focus, creates "discovery" or "tension"
- Pull out: Near to far; reveals the full picture, creates "release" or "isolation"
- Pan: Horizontal/vertical rotation; shows full spatial context; suits environment introductions and scene transitions
- Dolly: Camera translates laterally following subject; adds dynamism; suits walking, running, and shop-visit content
- Tracking shot: Follows moving subject, maintaining position in frame; suits person-following footage
- Handheld shake: Creates documentary feel and immediacy; suits vlog, street footage, and breaking events
- Gimbal movement: Silky-smooth motion; suits commercial ads, travel films, and product showcases
- Drone aerial: Large-scale overhead, follow, orbit, and fly-through shots; suits travel, real estate, and city promos
- Hard cut: The most basic and most used; fast pacing, high information density; suits fast-paced edits
- Dissolve (cross-fade): Two shots fade in/out overlapping; conveys time passage or emotional transition
- Mask transition: Uses in-frame objects (doorframes, walls, hands) as wipes; high visual impact
- Match cut: Consecutive shots share similar composition, movement direction, or color for visual continuity
- Whip pan transition: Fast camera swipe creates motion blur connecting two different scenes
- Zoom transition: Rapid zoom in/out creates a "warp" effect
- Flash white / flash black: Brief white or black screen; commonly used for beat-synced cuts and mood shifts
- Core transition principle: Transitions serve the narrative, not the ego - if a hard cut works, don't add a fancy transition
- White balance: Color temperature (warm/cool) and tint (green/magenta); ensure white is actually white
- Exposure: Overall brightness; use the histogram to avoid blown highlights or crushed shadows
- Contrast: Difference between highlights and shadows; affects the "clarity" of the image
- Highlights / shadows / whites / blacks: Four-way luminance fine-tuning
- Saturation vs. vibrance: Saturation adjusts globally; vibrance protects skin tones
- Primary correction goal: Make exposure, color temperature, and contrast consistent across all shots
- HSL adjustment: Independently adjust hue/saturation/luminance of specific colors (e.g., making only the sky bluer)
- Curves: RGB and hue curves for precision control - the core weapon of color grading
- Qualifiers / masks: Isolate specific areas or color ranges for localized grading
- Skin tone correction: Use the vectorscope to ensure skin tones fall on the "skin tone line"
- Sky enhancement: Independently brighten / add blue to sky regions for improved depth
- What is a LUT: Look-Up Table - essentially a preset color mapping
- Usage principle: A LUT is a starting point, not the finish line - always fine-tune parameters after applying
- Technical vs. creative LUTs: Technical LUTs convert LOG footage to standard color space (e.g., S-Log3 to Rec.709); creative LUTs add stylistic looks
- LUT intensity: Recommended opacity at 60%-80%; 100% is usually too heavy
- Custom LUTs: Export your frequently used grading parameters as a LUT for personal style consistency
- Cinematic: Low saturation + teal-orange contrast (shadows teal / highlights orange) + subtle grain
- Japanese fresh: High brightness + low contrast + teal-green tint + lifted shadows
- Cyberpunk: High-saturation neon (magenta/cyan/blue) + high contrast + crushed blacks
- Vintage film: Yellow-green tint + reddish shadows + grain + slight fade
- Morandi palette: Low saturation + gray tones + understated elegance; suits lifestyle content
- Consistency rule: Color grading style must be uniform within a single video and across a series
- Environment noise: First capture a pure noise sample (room tone), then use spectral subtraction tools
- Software tools: Premiere DeNoise, DaVinci Fairlight noise reduction, iZotope RX (professional grade), CapCut AI denoising
- Principle: Don't max out noise reduction strength (creates "underwater voice" artifacts); keeping 10%-20% ambient sound is actually more natural
- Wind noise: High-pass filter set to 80-120Hz to cut low-frequency wind rumble
- De-essing: Suppress sibilance ("sss" sounds) in the 4kHz-8kHz frequency range
- Rhythm markers: Listen through the BGM to find downbeats/accents; mark them on the timeline
- Visual beat-sync: Cut shots on downbeats/accents for audiovisual impact
- Emotional sync: Align BGM emotional shifts (intro->chorus, quiet->climax) with content mood changes
- BGM selection principles: Copyright-safe (use platform music libraries or royalty-free music), match content tone, don't overpower voice
- Not every beat needs a cut: Sync to "strong beats" and "transition points" only; cutting on every beat causes rhythm fatigue
- Ambient sound effects: Enhance scene immersion (street chatter, birdsong, rain, cafe ambience)
- Action sound effects: Reinforce on-screen actions (transition "whoosh," text pop "ding," click "clack")
- Mood sound effects: Set emotional atmosphere (suspense low-frequency hum, comedy spring boing, surprise "ding~")
- Sound effect sources: freesound.org, Epidemic Sound, CapCut sound library, self-recorded Foley
- Usage principle: Less is more - one precisely timed effect at a key moment beats wall-to-wall layering
- Voice is king: For talking-head / narration videos, voice at -12dB to -6dB, BGM at -24dB to -18dB
- Music-only videos (travel / landscape): BGM can go to -12dB to -6dB
- Sound effects level: Never louder than voice; typically -18dB to -12dB
- Loudness normalization: Final output at -14 LUFS (matches most platform recommendations)
- Avoid clipping: Peak levels should not exceed -1dBFS; maintain safety headroom
- EQ: Cut muddy low-frequency below 200Hz with a high-pass at 80-120Hz; boost the 2kHz-5kHz clarity range
- Compressor: Tame dynamic range for consistent volume (ratio 3:1-4:1, threshold per material)
- Reverb: Subtle reverb adds space and polish, but short-form video usually needs none or very little
- AI voice enhancement: Both CapCut and Premiere offer AI voice enhancement for quick processing
- Core concept: Define start and end states; software interpolates the motion between them
- Common animated properties: Position, scale, rotation, opacity
- Easing curves (the critical detail): Linear motion looks "mechanical"; ease-in/ease-out makes it natural - Bezier curves are the soul
- Elastic / bounce effects: Object slightly overshoots the endpoint and bounces back; adds liveliness
- Keyframe spacing: Tighter spacing = faster action; wider spacing = slower action
- Character-by-character reveal / typewriter effect: Suits suspenseful, tech-feel copy
- Bounce-in entrance: Text bounces in from off-screen; suits playful styles
- Handwriting reveal: Strokes drawn progressively; suits artistic and educational content
- Glitch text: Text jitter + chromatic aberration; suits tech / cyberpunk aesthetics
- 3D text rotation: Adds spatial depth and premium feel
- Short-video text animation rule: Keep animation duration to 0.3-0.5 seconds; too slow drags the pace, too fast is unreadable
- Common uses: Fireworks, sparks, dust motes, light bokeh, snow, fireflies
- CapCut: Built-in particle effect stickers; one-tap application
- After Effects / Fusion: Plugins like Particular for highly customizable particle systems
- Usage principle: Particle effects enhance atmosphere; they shouldn't steal the show
- Shooting tips: Light the green screen evenly with no wrinkles; keep subject far enough away to avoid spill
- Software keying: CapCut smart cutout (no green screen needed), PR Ultra Key, DaVinci Chroma Key
- Edge cleanup: After keying, adjust edge softness, spill suppression, and edge contraction to avoid "green fringe"
- AI smart cutout: CapCut's AI person segmentation works without green screen and keeps improving
- Constant speed change: Uniform speed-up or slow-down of an entire clip; suits timelapse / slow-motion
- Curve speed ramping (core technique): Achieve "fast-slow-fast" rhythm within a single clip
- Classic speed pattern: Pre-action slow-motion buildup -> action moment at normal speed -> post-action slow-motion savoring
- Beat-synced ramping: Return to normal speed on BGM downbeats; speed up between beats
- Frame rate requirement: Shoot at 60fps or 120fps for smooth slow-motion; 24/30fps footage will stutter when slowed
- Decorative text = stylized subtitles with design flair, used to emphasize key info or add fun
- Common styles: Stroke + drop shadow, 3D emboss, gradient fill, texture mapping
- Production tools: CapCut templates (fastest), Photoshop PNG imports, AE animated fancy text
- Design principle: Decorative text color must contrast with the frame (dark frames use bright text; bright frames use dark text + stroke)
- Layering: Bottom layer stroke/shadow + middle layer color fill + top layer highlight/gloss; aim for at least two layers
- Characteristics: Large font, high-saturation colors, exaggerated animations, paired with sound effects
- Common techniques: Text shake for emphasis, pulse scale, spinning entrance, emoji inserts
- Color rules: Different speakers get different colors; keywords pop in attention-grabbing colors (red/yellow)
- Placement rules: Don't block faces; stay within safe zones; vertical video subtitles go in the lower third
- Note: Variety-style subs suit entertainment / comedy / reaction content; don't overuse for educational or business content
- Use cases: Reaction videos, curated comments, multi-person discussions, creating busy atmosphere
- Implementation: Multiple subtitle tracks scrolling right to left at varying speeds and vertical positions
- Color and size: Mimic Bilibili (Chinese video platform) danmaku style; mostly white, key comments in color or larger text
- Pacing: Don't use wall-to-wall scrolling text - dense bursts at key moments, breathing room elsewhere
- SRT format: Most universal subtitle format; supported by virtually all platforms and players; plain text + timecodes
- ASS format: Supports rich styling (font/color/position/animation); commonly used for Bilibili uploads
- Bilingual layout: Primary language on top / secondary below; primary language in larger font
- Subtitle timing: Each line should last 1-5 seconds; appear 0.2-0.5 seconds early (so eyes can catch up)
- AI auto-subtitles + manual review: AI generates the draft saving 80% of time; then review line-by-line for typos and sentence breaks
- Font selection: For Chinese, use Source Han Sans / Alibaba PuHuiTi (free for commercial use); for titles, Zcool font series
- Font size guidelines: Vertical video body subtitles 30-36px, titles 48-64px; horizontal video body 24-30px, titles 36-48px
- Safe margins: Subtitles should not touch frame edges; maintain 10%-15% safe distance from borders
- Line spacing and letter spacing: Line height 1.2-1.5x; slightly wider letter spacing for breathing room
- Readability: Subtitles must be legible - use at least one of: semi-transparent backdrop bar, stroke, or drop shadow
- Resolution: 1080 x 1920 (standard) or 2160 x 3840 (4K vertical)
- Frame rate: 30fps (standard) or 60fps (sports/gaming content)
- Bitrate recommendation: 1080p at 8-15Mbps; 4K at 20-35Mbps
- Duration strategy: Douyin 7-15s (entertainment) / 1-3min (educational/narrative); Kuaishou (short-video platform) 15-60s; Xiaohongshu (lifestyle platform) 1-5min
- Safe zones: Leave 15% padding at top and bottom (platform UI elements will overlap)
- Resolution: 1920 x 1080 (standard) or 3840 x 2160 (4K)
- Frame rate: 24fps (cinematic), 30fps (standard), 60fps (gaming/sports)
- Bitrate recommendation: 1080p30 at 10-15Mbps; 4K60 at 40-60Mbps
- YouTube tip: Upload at maximum quality; YouTube automatically transcodes to multiple resolutions
- Bilibili tip: Uploading 4K+120fps qualifies for "High Quality" badge and traffic boost
- The thumbnail is your video's "headline" - 80% of click-through rate is determined by the thumbnail
- Vertical thumbnail composition: Person fills 60%+ of frame + large title text (3-8 characters) + high-contrast colors
- Horizontal thumbnail composition: Text-left/image-right or text-top/image-bottom; key info centered or slightly above center
- Thumbnail text: Must be large (readable on phone screens), short (scannable in a glance), compelling (suspense or value)
- Facial expressions: Thumbnail faces should be exaggerated - surprise, joy, confusion; neutral expressions don't generate clicks
- A/B testing: Prepare 2-3 different thumbnails per video; track CTR data post-publish to select the winner
- H.264: Best compatibility, moderate file size, first choice for most scenarios
- H.265 (HEVC): 30-50% smaller files at same quality, but some older devices can't play it
- ProRes: High-quality intermediate codec in Apple ecosystem; for footage needing further processing
- Audio encoding: AAC 256kbps stereo (standard) or 320kbps (high quality)
- Pre-export checklist: Resolution correct? Frame rate matches source? Bitrate sufficient? Audio plays normally?
- Folder structure: Organize by project / date / asset type (video/audio/images/subtitles/project files) in hierarchical directories
- File naming convention: date_project_shot-number_description, e.g., "20260312_product-review_S01_unboxing-closeup"
- Proxy editing: Generate low-resolution proxy files from 4K/6K raw footage for editing, then relink to originals for final export - this is a lifesaving technique for high-res workflows
- Backup strategy: 3-2-1 rule - 3 copies, 2 different storage media, 1 off-site backup
- Asset tagging and rating: Preview all footage after import, rate shot quality (good/usable/discard) to avoid hunting during editing
- Project templates: Preset timeline track layouts, frequently used color presets, subtitle styles, intro/outro sequences
- CapCut template ecosystem: Create reusable templates -> one-click apply -> just swap footage and copy
- PR templates (MOGRT): Build Essential Graphics templates in AE; modify parameters directly in PR
- Batch export: DaVinci Resolve render queue, PR's AME queue, CapCut batch export
- Efficiency gain: After templating, per-video production time drops from 2 hours to 30 minutes
- Project file management: Standardize software versions, project file storage locations, and asset link paths
- Division of labor: Rough cut (pacing and narrative) -> fine cut (transitions and details) -> color grading -> audio -> subtitles -> export
- Version control: Save as new version for every major revision (v1/v2/v3); never overwrite the original file
- Delivery spec document: Define resolution, frame rate, bitrate, color space, and audio format requirements
- Review process: Use Frame.io or Feishu (Lark) multi-dimensional tables for timecoded review annotations
- Core philosophy: Mouse operations are the least efficient - every frequent action should have a keyboard shortcut
- Essential shortcuts (PR example): Q/W (ripple edit), J/K/L (playback control), C (razor), V (selection), I/O (in/out points)
- Custom shortcuts: Bind most-used operations to left-hand keys (since right hand stays on the mouse)
- Mouse recommendation: Use a mouse with programmable side buttons; bind undo/redo/marker to them
- Efficiency benchmark: A proficient editor should perform 80% of operations without touching the menu bar
- CapCut AI subtitles: 95%+ accuracy, supports Chinese, English, Japanese, Korean, and more; one-click generation
- OpenAI Whisper: Open-source model, works offline, supports 99 languages, extremely high accuracy
- ByteDance Volcano Engine ASR: Enterprise API, suits batch processing
- AI subtitle workflow: AI draft -> manual review (focus on technical terms, names, homophones) -> timeline adjustment -> style application
- Important note: AI subtitles aren't 100% accurate - technical jargon, dialects, and overlapping speakers require manual review
- CapCut "text-to-video": Input text and auto-match stock footage, voiceover, subtitles, and BGM
- CapCut "AI script": Input a topic and auto-generate script + storyboard suggestions
- Use cases: Rapid drafts for news-style / talking-head / image-text videos
- Limitations: AI-generated videos are "watchable but soulless" - they handle 60% of the work, but the remaining 40% of creative refinement still requires human craft
- CapCut AI cutout: Real-time person segmentation without green screen; already quite good
- Runway ML: Professional AI keying and video generation tool
- Use cases: Background replacement, picture-in-picture, green screen alternative
- Edge quality: Hair, semi-transparent objects (glass/smoke) remain challenging for AI; manual touchup needed when critical
- Suno AI / Udio: Input text descriptions to generate original music; specify style, mood, and duration
- Use cases: Quickly generate custom music when you can't find the right BGM; avoid copyright issues
- Copyright note: Confirm the commercial licensing terms for AI-generated music; policies vary by platform
- Quality assessment: AI music is sufficient for simple scoring; complex arrangements and vocal performances still fall short of human creation
- Tools: CapCut digital avatar, HeyGen, D-ID, Tencent Zhi Ying
- Use cases: Batch-producing educational / news content, substitute when on-camera talent isn't available
- Current state: Lip sync and facial expressions are fairly natural now, but the "clearly a digital avatar" feeling persists
- Usage recommendation: Use as a supplement to real on-camera talent, not a replacement - audiences trust real people far more
