A free, reusable worksheet for comparing browser face-swap previews under consistent conditions. The ZIP includes a plain-text guide and an editable CSV with eight test rows: setup, neutral baseline, speech, head turn, hand occlusion, lighting change, recovery, and final source/output comparison. Each row has space for edge stability, expression tracking, latency, and timestamped observations. Use a reference photo only with permission, keep camera and lighting fixed, and preserve the unmodified source clip. A single appealing frame is not a reliable quality test; the worksheet encourages you to note where tracking fails and how quickly it recovers. For a browser example, try live swap face at https://liveswapface.com/ with a gallery choice or a photo you may use. The worksheet also works with other tools. The web preview is available now; the desktop virtual-camera app is still listed as coming soon. This download is the worksheet itself, not the face-swap software. It contains README.txt and face_swap_test_worksheet.csv, both editable and usable offline. No purchase or account with the linked tool is required to use the worksheet.
