VA Prepare • Spikelets

Example of a VA Premium source prepare: 4:2:0 → 4:2:2 10 bit.

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 Sony NEX series. A sensor reading resolution is limited, so we have aliasing artifacts. Also this camera video file has a very low AVCHD 1.0 bitrate: ~17 Mbps. The image has color aliasing artifacts, also a resolution is very low.

It is 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 visible. I used additional denoise and antialiasing filters to get better result. I did not used a sharping in this example, but it is easy to add.
