Some SD content is listed as HD content in my library (actual Kodi 21 nightly, but behaviour also present with previous versions).

What rules does Kodi use to determine whether content is HD or SD?
Can I set somewhere that only resolutions greater than or equal to 720p are listed as HD?
When it comes to naming, I'm already working with "hdtv" and "sdtv".

I've picked some examples from a TV-show in my library:
S03E03 - Show-name.hdtv.mkv -> Resolution is 1280x720 -> Is correctly listed as HD
S03E02 - Show-name.sdtv.mkv -> Resolution 1024x576 -> Is also listed as HD 720 in Kodi -> incorrect according to my understanding
S02E04 - Show-name.sdtv.avi -> Resolution 656x368 -> Is correctly listed as SD

Can I influence this somehow (e.g. via the as.xml)?

S03E02 - Show-name.sdtv.mkv -> Resolution 1024x576

Can you post the MediaInfo output of this episode please?

[guenzelsen]

Please find the output from the mentioned file below.
Another observation: If a video is in 16:9 format with height 576, it's recognized as HD 720.
If a video is in 4:3 format with height 576 (width 720), it's recognized as SD (let me know, if you need a mediainfo from such file also).

The 'rules' for determining the resolution are as follows

cpp:
if (iWidth == 0 || iHeight == 0)

    return "";



  else if (iWidth <= 720 && iHeight <= 480)

    return "480";

  // 720x576 (PAL) (768 when rescaled for square pixels)

  else if (iWidth <= 768 && iHeight <= 576)

    return "576";

  // 960x540 (sometimes 544 which is multiple of 16)

  else if (iWidth <= 960 && iHeight <= 544)

    return "540";

  // 1280x720

  else if (iWidth <= 1280 && iHeight <= 962)

    return "720";

  // 1920x1080

  else if (iWidth <= 1920 && iHeight <= 1440)

    return "1080";

  // 4K

  else if (iWidth <= 4096 && iHeight <= 3072)

    return "4K";

  // 8K

  else if (iWidth <= 8192 && iHeight <= 6144)

    return "8K";

  else

    return "";

As you can see, both width and height are taken into consideration. I'm not aware of anything in AS.xml to override that. hdtv and sdtv in filenames will only benefit you, unless you are using a skin that specifically looks for that information.

Thanks
I can now understand the logic behind.
However it still feels wrong that for example 4:3 DVD files are labled as SD, while 16:09 DVD files are labled HD 720.

However it still feels wrong that for example 4:3 DVD files are labled as SD, while 16:09 DVD files are labled HD 720.

As said at Kodinerds as well, the presented mediainfo output is not the original video file which was downloaded from german mediatheks. The original file, which I now downloaded myself, has the resolution 720*576. That's what it is. The user modified the video and stretched it and therefor changed the resolution. Because of the logic mentioned before and the fact the current video is different from the orignal one, it's pretty clear that Kodi shows it as HD. Normal DVD files don't have a 1024*576 resolution. Those are bound to 720*576.

The mediainfo from the original file is:

As you can see, the original video is pretty clear for its resolution and AR (aspect ratio):

Width                                    : 720 pixels
Height                                   : 576 pixels
Display aspect ratio              : 16:9

So there's no need to modify the video at all. Kodi will play the video in 16:9 pretty fine (I tested with current master from today). But, and that's totally fine, if you modify the video and make it different from the origin, then it's clear that Kodi might show something different than the source you got it from.

Correct
My DVD example was insufficient.
Especially as the above mentioned TV-Show episode is not a DVD format.

1024x576 is PAL-wide, which is SD content.
Kodi lables this as HD 720.

Suggestion is, to change the logic in Kodi to have a more accurate file labeling.
