Video Optimization Best Practices

File Size Reduction

1. Lower resolution when platform doesn’t support high-res playback
2. Reduce bitrate using compression tools like HandBrake
3. Trim unnecessary footage from beginning and end
4. Use modern codecs like H.265 (HEVC) where supported

Cross-Platform Efficiency

1. Create in highest quality first, then resize down for other platforms
2. Design for vertical first (9:16) when possible, as it’s easiest to crop to other formats
3. Keep important content centered so it remains visible when cropped
4. Batch export to multiple formats using tools like Adobe Media Encoder

Performance Optimization

1. Front-load your content – put the most engaging elements in the first 3 seconds
2. Use platform-specific features (TikTok effects, Instagram filters)
3. Test different lengths for each platform to find your audience’s sweet spot
4. Consider audio design for platforms where sound is on by default (TikTok) vs. off (Facebook)

FAQs

What’s the best video length for engagement?

• TikTok: 15-30 seconds
• Instagram Reels: 15-30 seconds
• YouTube Shorts: 15-60 seconds
• Standard YouTube: 8-12 minutes
• Facebook: 1-3 minutes

Why is my video quality degrading when uploaded?

Social platforms compress videos after upload to save bandwidth. To minimize quality loss:

1. Upload at the maximum recommended resolution
2. Use moderate movement (excessive motion causes more compression artifacts)
3. Ensure good lighting in the original footage
4. Export at a slightly higher bitrate than recommended

How can I repurpose one video across multiple platforms?

1. Shoot in high resolution (4K if possible)
2. Frame shots to work in both 16:9 and 9:16 (leave room in the center)
3. Use tools like Kapwing or Adobe Premiere to create platform-specific versions
4. Adjust pacing and length for each platform’s audience

Does video file size affect reach and distribution?

Yes, especially on mobile networks. Smaller files:

• Load faster, reducing abandonment
• Buffer less frequently
• Are more likely to be watched to completion
• Save users’ data (which they appreciate)

Balance quality with file size for optimal performance.
