v2mixer.livev2.com- 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.
