  • image quality after zooming in

    my original material is 1920 * 1080.

    I enlarged the image with the layouter.

    From 100 % to 110 %, sometimes 130 %.

    If I screen the result in the cinema, could this cause any major problems with the image quality?

    Please try to use lanczos in the layouter.
    Lanczos will give better scaling results compared to the default setting.

      If you are going to do a lot of zooming in or panning around the shot, it is best to shoot in UHD then you can zoom in with no quality loss in an HD project.

      HD footage in an HD project maximum of 115% zoom in otherwise it will go soft, to recover it a bit I like to apply the Matrix sharpness to the zoomed in result and play with the numbers in the 3 columns and looking at it on a large 4k TV until it looks best.

      That Matrix filter takes a a bit of getting used to

      The sharpness filter can add edge enhancement which doesn't look as nice as the Matrix filter.
