FAQs
What is the best quality for screen recording?
1080p at 30fps is ideal for most tutorials and presentations. Use 60fps for smooth motion or gaming. 720p is good for smaller file sizes.
How much storage do I need?
A 10-minute 1080p video at 30fps typically requires 400-600 MB. Plan for 1GB per 15-20 minutes of HD recording.
Should I record system audio or microphone?
For tutorials, record both system audio (for software sounds) and microphone (for narration). For presentations, microphone is usually sufficient.
What is the best screen recording format?
MP4 (H.264) for compatibility, MOV for Mac, WebM for web. Settings: 1080p @ 30fps for tutorials, 60fps for gaming. Bitrate: 5-8 Mbps for 1080p. Use variable bitrate (VBR) for optimal size/quality. Save originals losslessly if editing later.
How much storage do screen recordings use?
1 hour 1080p: 2-4 GB (compressed), 10-20 GB (uncompressed). Factors: resolution, frame rate, motion complexity, compression. Record at final resolution. Clean up regularly. Use cloud storage for archives. Consider streaming services for large files.
What should I record for software tutorials?
Plan content, write script, prepare examples. Record at 1920×1080, 30fps. Include: clear audio, mouse highlighting, keyboard shortcuts display, slow down for complex steps. Edit: add annotations, zoom to important areas, remove mistakes, add intro/outro. Keep videos under 10 minutes.
