Question about De-interlacing Filters
Posted: Mon Jan 06, 2020 10:22 pm
Description of problem or question:
Just A Quick Question, what is the most common type of de-interlacing filter called that is very simple and only blurs the source to try to remove the interlace combing artifacts?
I'm trying to compare the most simple de-interlace filter to the much more advanced and very complex edge-directed de-interlace filters that we now have like EEDI2 which upscale the image by 2x and interpolate the missing field, thereby filling in the missing lines by preserving the edges. EEDI2 is quite an excellent and high quality filter that works very well at preserving the edges, lines and details while removing the interlacing artifacts.
Please tell the name of the most common and simple de-interlacing filter that just blurs the image itself and tell me what type of algorithm the filter uses, like Bilinear algorithm filter. The reason why I ask is I know that there's a common de-interlace filter that's very low quality, simplistic, and just blurs the image itself but doesn't really work on calculating how to adequately remove the lines themselves as the algorithmic formula is quite weak, I just don't remember what it's called. I don't know if it's the "Blend" filter that VLC uses or if I'm thinking of something else.
Steps to reproduce the problem (If Applicable):
N/A
HandBrake version (e.g., 1.0.0):
HandBrake Version 1.3.1
Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Macintosh OS X 10.13 High Sierra
HandBrake Activity Log ***required*** (see How-to get an activity log)
