Random video degradation in different encoding options

[gelo333]

From this entire topic, I concluded that it is better to look with your brain based on the logic of the software, and not look with your eyes, studying small details in many videos. Even if the result is not optimal, otherwise the process may turn into infinity. You can't get anything brilliant from a encoder, so accept a compromise.

I still have a question about the size of video files and the action of the sharpener. It didn't work out for me with Finesharp, so I tried the closely related DetailSharpen.

Fully script

LSMASHVideoSource("C:\Videos\movie.mp4")
SetFilterMTMode("DEFAULT_MT_MODE", 2)
Spline36ResizeMT(720, 1280, prefetch=4)
KNLMeansCL(D=1, A=1, h=1.5, device_type="auto")
DetailSharpen(str=0.3, pow=7, z=6, ldmp=0, mode=1, med=false)
Prefetch(6)

I take the first video I receive as a reference point to compare with other results, and then change the DetailSharpen settings.

1. DetailSharpen(str=0.3, pow=7, z=6, ldmp=0, mode=1, med=false)
file size 10,849,597 bytes
disk size 10,850,304 bytes

2. DetailSharpen(str=0.29, pow=6, z=7, ldmp=0, mode=1, med=false)
file size 10,849,491 bytes
disk size 10,850,304 bytes
the picture is different from all other videos

3. DetailSharpen(str=0.31, pow=7, z=6, ldmp=0, mode=1, med=false)
file size 10,849,597 bytes
disk size 10,850,304 bytes
the picture is the same as in the first result

4. DetailSharpen(str=0.28, pow=7, z=7, ldmp=0, mode=1, med=false)
file size 10,849,600 bytes
disk size 10,850,304 bytes
the picture is the same as in the first result

5. DetailSharpen(str=0.3, pow=9, z=6, ldmp=0, mode=1, med=false)
file size 10,849,600 bytes
disk size 10,850,304 bytes
the picture is the same as in the first result

I removed FFMPEG and Avisynth. Cleaned the registry. Installed the latest versions of FFMPEG and Avisynth. The error persists.
