Artemis Medium Quality 100%(Denoise/Deblock )
In use, I have encountered bad image errors when sharpening.
I decided to find out why.
Here is what I found
When working with #Artemis Medium Quality 100%(Denoise/Deblock )# visible lines appear on the image, after a series of experiments, I realized that when processing the AI Artificial image, the model will compress in height picture by 2-4 times, which is why various image errors appear.
How to get the correct image.
To do this, you need to stretch the image in height by 2-4 times.

We get

Compressing the width and height of the file. 1440:1080
-aspect 1.3333 (1440)/(1080)=1.3333
ffmpeg -i TEST_scale_1x_amq-13.mov -vf colorkey=0x00FF00 -filter:v scale=1440:1080 -aspect 1.3333 -map 0:0 -c:a copy -b 0 -q -1 -c:v mpeg2video -profile: v high -b 800000000000 test2.ts
