Video Optimization Best Practices
The quality of your search results depends on the quality of your video. This guide covers how to shoot, edit, and optimize your videos for maximum accuracy with SearchByVideo' AI analysis.
Recording Best Practices
Lighting
Why it matters: Poor lighting is the biggest factor reducing AI accuracy. Faces, objects, and text become harder to identify.
Optimal lighting setup:
- Key light (front): 45° above, slightly to the side
- Fill light (opposite): Reduces harsh shadows
- Back light: Separates subject from background
- Avoid: Direct backlighting, single harsh source, flickering lights
Quick tips:
- Shoot during daylight if possible
- Use soft diffusion (white fabrics, bounce boards)
- Avoid bright windows behind subject
- Use white balance correction (manual white balance in camera)
- Test lighting before recording
Impact on AI: ⭐⭐⭐⭐⭐ Critical
Camera Stability
Why it matters: Shaky footage creates motion artifacts that confuse the AI visual analysis.
Best practices:
- Use tripod or stable mount
- Enable optical image stabilization if available
- Avoid handheld for static content
- Use gimbal for dynamic movement (walking, panning)
- Lock down camera for interviews
Tools:
- Tripod/monopod ($30-200)
- Gorilla pod ($15-30)
- Phone stabilizer gimbal ($50-150)
- Built-in stabilization (software or hardware)
Impact on AI: ⭐⭐⭐⭐
Audio Quality
Why it matters: Clear audio improves dialogue detection and transcript accuracy.
Optimal setup:
- Microphone: Lavalier, shotgun, or quality USB mic
- Distance: 6-12 inches from mouth
- Room: Minimize echo and background noise
- Levels: -12dB to -6dB (not clipping)
- Format: Stereo or mono, 44.1kHz or higher
Reduce noise:
- Record in quiet space
- Use noise-canceling microphone
- Avoid wind (use windscreen)
- Close windows and doors
- Turn off AC/fans temporarily
- Record during quieter times
Bad audio signals:
- ❌ Echoey rooms
- ❌ Heavy background noise
- ❌ Clipping/distortion
- ❌ Too quiet (below -18dB)
- ❌ Inconsistent volume
Impact on AI: ⭐⭐⭐⭐⭐ Critical for dialogue/transcription
Resolution & Frame Rate
Recommended settings:
- Resolution: Minimum 720p (1280x720), 1080p (1920x1080) ideal
- Frame rate: 24p or 30p (24p for cinematic, 30p for most content)
- Bitrate: High bitrate (10-25 Mbps) reduces compression artifacts
- Codec: H.264 or H.265 (modern)
Avoid:
- ❌ Low bitrate (<5 Mbps) causes compression artifacts
- ❌ Interlaced video (i, not p)
- ❌ Variable frame rate (VFR) for longer content
- ❌ 4K if not necessary (larger files, longer analysis)
Impact on AI: ⭐⭐⭐⭐
Focus and Exposure
Auto-focus considerations:
- Keep subjects within focus range (1-6 feet typically)
- Avoid thin depth of field (very soft background) for faces
- Use continuous autofocus for moving subjects
- Manual focus works great for static content
Exposure settings:
- Proper exposure (not underexposed)
- Avoid blown-out highlights (especially on faces)
- Use exposure compensation for backlit subjects
- Check histogram while recording
Impact on AI: ⭐⭐⭐⭐
Motion Considerations
Good movement:
- ✅ Slow, intentional camera motion
- ✅ Subject walking or moving smoothly
- ✅ Smooth pans and tilts
- ✅ Zoom during pauses, not during action
Problematic movement:
- ❌ Rapid shaking
- ❌ Sudden zooms during speech
- ❌ Erratic framing
- ❌ Overly fast pans
Impact on AI: ⭐⭐⭐
Pre-Upload Editing
File Format Optimization
Best formats for SearchByVideo:
- MP4 (H.264) — Most compatible, good quality/size ratio
- MOV (ProRes) — High quality, larger files
- WebM — Web-native, good compression
- MKV — High quality, more complex
Avoid:
- ❌ AVI (outdated codec)
- ❌ FLV (outdated)
- ❌ Highly compressed formats
Trimming and Cleanup
Before uploading:
- Remove long silent intros/outros
- Trim dead air longer than 5-10 seconds
- Remove irrelevant sections (setup, technical issues)
- Cut major audio problems (if possible)
Why? Cleaner content = faster analysis, better results
Color Correction
Basic corrections improve AI accuracy:
- Fix white balance (should be accurate)
- Adjust exposure (neither too dark nor blown out)
- Normalize saturation (not oversaturated)
- Remove color casts (greenish, blueish tints)
Tools:
- Adobe Premiere Pro
- DaVinci Resolve (free)
- Final Cut Pro
- Shotcut (free)
Impact on AI: ⭐⭐⭐
Normalize Audio
Audio processing:
- Normalize levels (-3dB to -1dB)
- Reduce background noise if severe
- Balance different speakers (interview)
- Remove pops and clicks if major
Tools:
- Adobe Audition
- Audacity (free)
- Logic Pro
- GarageBand
Impact on AI: ⭐⭐⭐ (for dialogue detection)

Post-Upload Optimization
Segment Selection
If videos are over 15 minutes:
- Consider splitting into chapters
- Upload longer videos during off-peak hours
- Focus searches on specific chapters
Search Query Optimization
Based on your content quality:
For well-lit content:
- More specific queries work better
- "person wearing red jacket looking upset"
For lower light:
- Keep queries simpler
- "person looking sad"
- Focus on actions rather than subtle expressions
Troubleshooting Specific Issues
"Results don't match my content"
Likely causes:
- Poor video quality
- Insufficient lighting
- Shaky camera work
- Low bitrate (compression artifacts)
Solutions:
- Re-record with better lighting
- Use stabilizer next time
- Export at higher bitrate
- Use simpler search terms
"Dialogue detection missing speech"
Likely causes:
- Poor audio quality
- Background noise too loud
- Inconsistent levels
- Heavily compressed audio
Solutions:
- Re-record with better mic
- Minimize background noise
- Normalize audio levels
- Use lossless or high-bitrate audio
"Scene change detection missing transitions"
Likely causes:
- Overlapping audio between scenes
- Gradual transitions (fades, dissolves)
- Insufficient lighting difference
- Too many similar scenes
Solutions:
- Use clean cuts (hard cuts)
- Increase lighting difference between scenes
- Use distinct audio cues
- Vary backgrounds/angles between scenes
"Object detection misses important elements"
Likely causes:
- Objects too small in frame
- Poor focus
- Insufficient lighting on object
