How PEF Handles ASF Data
For video-to-image conversions, Xonvert applies format-aware algorithms that respect the unique characteristics of both ASF Container and PEF Raw Photo. Cross-category conversions require additional adaptation, which Xonvert handles automatically. Frame rate, resolution, and aspect ratio are maintained during conversion. Xonvert avoids unnecessary re-encoding when possible. When converting from ASF Container to PEF Raw Photo, the conversion is lossless, meaning every bit of data is preserved exactly as in the original.
Extracting an image from ASF Container video produces a single frame snapshot in PEF Raw Photo format. This is ideal for creating thumbnails, capturing specific moments from footage, or generating preview images for video content. Xonvert extracts the first frame at its original resolution.
Important: Converting from lossy ASF to lossless PEF does not restore previously discarded data. The output perfectly preserves your current file quality without adding further degradation, but quality lost during the original ASF encoding cannot be recovered.
