Effect Zoom Encode - v2Mixer 官方

the Effect Zoom Encode for Video Editor
function for
- control the image zoom quality for video encoder, is the movie final out.
the dialog
the parameters
- Type, values:
  - point, the point to point, mean 1:1 resize, for pixel-art video, such comic
    - 1:1 mean never considers the surrounding color and will not gradient.
    - it is very important for animation/comic with clear lines
  - fast bilinear, the bilinear fast version, is antialiasing technique, for example zoom out let up,down,left,right 4 point help to 1(it self).
    - but when 1000 to 200, then the left and right pixels are far away from each other, so ignoring many pixels between them.
    - so example pixels white,red,red,red,black as 1, will just count the white and black, but the three of red got ignore..
      - so we got gray, should be gray + red
    - this just one of example for why it named fast. but this's default option, because count the three of red is very heavy job.
    - in v2mixer only this type running in parallel(use all you cpu cores) mode.
  - bilinear, the bilinear type, also 4 point to 1
    - see above about fast version, this type will count the three of red.
    - so you need a powerful processor.
  - bicubic, the bicubic type, mean 9 point to 1
    - an pixels zoom from 3x3 to 1, see above fast bilinear type, this type also count the three red.
    - so you need a very powerful processor.
  - ~~compensation~~, mean N point to 1
    - an pixel zoom from NxCxR to 1, N/C/R are result from near detect by current salient partto.
    - N mean how salient with last frame, C mean how salient of near, R mean result of bicubic.
    - deprecated, because very slow, may back future with chips support.
note
- unlike Zoom Decode, that's for Decoder, this's for Encoder.
- the encode image(video) quality only depend this value, doesn't control by any other value.
  - if current chapter(video) never zoom(resize), just ignore this Effect, because 1:1 copy doesn't have the quality.
- usually, in edit step try lower value to speed up the preview. before export, change to hight value, export is the background job you can wait for.
  - the fast bilinear enough by default, unless you zoom in 640x360 to 1920x1080 or zoom out > 2 ratio
  - if not enough, tell us, we will focus on optimizing them.
