deinterlace deep settings

Post by cosmoxl » 09 Feb 2018, 02:06

As I've grown more experienced with using yadif 2x on the ATV4k I've come to the conclusion that the algorithm isn't looking at the whole screen to decide cadence but only (probably) the center. Whenever the image in the center of the screen is still, yadif 2x is thrown off and skipping or dropping happens. As soon as the center starts moving it locks on to the cadence again.

My requests is that if there are deep settings in the yadif2x code that control what part of the image is inspected, that that area of inspection be increased to include the whole image or a bigger part of the image. Even better is to possibly reveal that setting to the user.

Thanks!

Investigate yadif for FFMpeg, I'm sure they have lots of diddle factors :)

Unfortunately, it doesn't seem they do. https://ffmpeg.org/ffmpeg-filters.html#yadif-1

But, there are some other deinterlacers in there that might be fun to mess with. :P
