This Video Artifact Premium example shows a typical post-production source quality restoration. The original video is a 1920x1080 25p AVCHD MTS file from Sony NEX-5. This camera is the first model from the Sony NEX series. The sensor reading is limited, so we have aliasing artifacts. Also it uses very low AVCHD 1.0 bitrate ~17 Mbps. The image has color aliasing artifacts, and resolution is very low.
It is too simple to remove these artifacts with VA Premium. But this example has a complication. There is a small sharping against the sky. So compression artifacts are very visible. I used more denoising and more antialiasing to get better result. Only non-important image areas get details lost. I did not used sharping in this example, but is too easy to add it. I have checked it, no artifacts after sharping is visible.
The source, 4:2:0 H.264 video from Sony NEX-5, 2x crop.
A background digital noise is removed, 4x crop.
Camera sharping and H.264 compression artifacts are removed, 4x crop.
Digital camera sensor aliasing and compression aliasing are both removed, 4x crop.
Chromatic aberrations are removed, 4x crop.
