Tips for Better Videos
Plan your recording
Outline what you’ll demonstrate before recording. This reduces editing time and creates smoother content.
Use zooms sparingly
Only zoom to highlight important actions. Too many zooms can be distracting.
Match your aspect ratio to the platform
- 16:9 for YouTube, tutorials, and presentations
- 9:16 for Instagram Stories, TikTok, and mobile
- 1:1 for Instagram feed and Twitter
Test your export settings
Export a short section first to check quality and file size before rendering the full video.
Keep backgrounds simple
Solid colors or subtle gradients work better than busy wallpapers for professional demos.
