This example of Video Artifact Premium shows a resize result from a video source that has halos after camera sharping. The original source is a 1920x1080 H.264 file from Panasonic GH3.
I removed compression artifacts and noise. VA has good linear color space resize filters. But after resize we can see ugly halos, so camera sharping should be removed. I used a de-halo filter. After resize additional small sharpness correction compensates a micro detail lost. The image is now clear and ready to montage. It seems blurry, but you can always add sharping later, if required.
