FAQ – Frequently Asked Questions

Can ScreenNinja record multiple monitors simultaneously?

Yes. When you start a new recording, you can select “All Screens” to capture the combined desktop area across multiple monitors. The resulting video will retain the relative positions of each monitor.

Is there a limit to the length of a time‑lapse session?

ScreenNinja does not impose a hard time limit. The only constraints are available disk space and system resources. For very long sessions, it’s advisable to monitor storage usage periodically.

How does ScreenNinja handle privacy and data security?

All recordings are saved locally on your machine; no data is uploaded to the cloud unless you manually share it. The installer is digitally signed, and the application checks for updates over HTTPS to prevent tampering.

Can I customize the output video’s bitrate or codec?

The built‑in export dialog offers basic bitrate presets (Low, Medium, High). For advanced codec settings, you can export as an image sequence and use a third‑party encoder such as HandBrake or FFmpeg.

Is there a way to schedule recordings to start automatically?

ScreenNinja includes a simple scheduler in the “Advanced” tab where you can set a start time and duration. This feature works on Windows and macOS; Linux users can achieve similar results using cron jobs combined with command‑line arguments.
