Yes. This tool follows a local-first approach in normal usage, so your source data stays on your device.
For typical usage, use exact positions (time/page/frame/range) instead of rough dragging when precision matters. Validate boundary points before exporting the final segment. This helps keep outputs consistent across different devices.
Practically speaking, yes. Extraction creates independent outputs that can be transformed, merged, or repurposed in subsequent steps without touching the original file. That makes the result easier to verify before publishing.
In day-to-day use, mismatches usually come from approximate range selection or source profile differences. Re-check boundaries and normalize sources when needed. This is usually the most reliable approach for repeatable results.
