Conversion Error - Quantization
"Quantization" is a result of reprocessing an image through compression, scaling and/or interpolation, causing the image to appear "blocky", aliased, or un-sharpened.
Quantization impacts the technical and content quality of the asset. The image will appear to be blurry or blocky, and noticeably compressed. Image quality will be very degraded and the customer experience will be adversely affected. This is possibly the creative intent. Assets created from this source will contain quantization.
The shot is of a lower quality compared to its adjacent shots; it is noticeably blown up and the image lacks sharpness; there is macroblocking on the edges of shapes. The quantization is possibly due to rendering or VFX output settings.
Context clues are present that indicate footage is meant to be degraded or is archival.
Shot is of much lower image and pixel quality than shots surrounding it. Noticeably blown up and image lacks sharpness. Possibly due to rendering or VFX output settings. Macro blocking occurs on the edges of shapes.
How to Prevent:
Minimize use of compression, scaling or interpolation.
Shoot at a higher resolution than intended in order to have room for framing without compromising quality.
Shot or scene must be replaced with the same content in higher quality.
