Nhật ký phóng to: Lanczos3, không tạo chi tiết mới

Đọc thuật toán của lượt đó. Ảnh mặt người không được vẽ thêm. Đây không phải công cụ phục hồi khuôn mặt.

Chưa có trang Labs hub tiếng Việt. Trang báo cáo này là chỗ đọc bằng tiếng Việt.

Preset chất lượng là Tốt nhất (Lanczos3), Cân bằng (bicubic) và Nhanh (bilinear). Đích xuất gồm 1080p, 1440p, 4K UHD, 2× và cỡ tùy chọn trong giới hạn của control. Tùy chọn trên một ca là control đã bấm, không phải danh sách preset chưa ai chạy.

Bộ lấy mẫu hiện làm việc với khung SDR 8-bit. HDR và màu 10-bit không phải đường hứa giữ nguyên. Tiếng tương thích được chép khi hộp đầu ra chứa được. Thẻ hộp thông thường bị bỏ khi “Xóa metadata” còn bật, và đó là mặc định.

Khung lớn hơn thường thành tệp lớn hơn. Số byte trên từng ca là kích thước đã ghi. Trang này không đổi chúng thành điểm chất lượng. SIMD được dùng khi trình duyệt có; đó không phải tốc độ đo cho mọi người xem.

• Đây không phải phóng to bằng mô hình sinh hoặc khuếch tán.
• Con số thời gian chỉ xuất hiện khi probe của ca đó đã ghi lại.

Cặp khung hình và crop chi tiết

Các ảnh này là cặp khung hình hoặc crop chi tiết được lưu cùng ca. Đổi chiều rộng hoặc chiều cao là phép đổi kích thước toán học đã ghi, không phải chi tiết ảnh mới.

Giới hạn đã ghi cho ca này

• The upscaler control is mathematical resampling (Lanczos3, bicubic, or bilinear), not a generative model.
• Capture instrumentation aborts known preexisting Cloudflare telemetry at static.cloudflareinsights.com and /cdn-cgi/rum before transmission. That block is not evidence that production has no analytics.

Ảnh màn hình lúc ghi

Câu hỏi thường gặp

1080p lên 4K có nghĩa là nét như quay 4K không?

Không. Đó là phóng khung bằng toán. Chi tiết không có trong frame gốc không được bịa ra.

Audio có bị nén lại không?

Đường tiếng được chuyển lại nguyên bitstream khi công cụ làm được. Báo cáo lượt đó ghi rõ nếu không.

Cặp khung hình và crop chi tiết

Các ảnh này là cặp khung hình hoặc crop chi tiết được lưu cùng ca. Đổi chiều rộng hoặc chiều cao là phép đổi kích thước toán học đã ghi, không phải chi tiết ảnh mới.

Giới hạn đã ghi cho ca này

• The upscaler control is mathematical resampling (Lanczos3, bicubic, or bilinear), not a generative model.
• MC-VID-001 is 64x48, about 1 second, 12 fps, and 7209 bytes. It is a limitation case, not a quality benchmark.
• Capture instrumentation aborts known preexisting Cloudflare telemetry at static.cloudflareinsights.com and /cdn-cgi/rum before transmission. That block is not evidence that production has no analytics.
