can a mkv or video file be both 1200p and 1080p? (lemmy.ml)

I've seen some torrents incorporating both standards in their description and I don't get it. It's either 1200p (1920x1200, WUXGA) or 1080p (1920x1080, Full HD).

What am I missing?

Yes, I've seen a video file that changes resolution mid-video, but it's more of a party trick since not all players handled it well

Specifically, I saw a group chat program rendered it "correctly" (Discord? I don't remember), so the embedded video would re-flow the rendered chatroom while playing

Discord definitely supports this, I’ve seen meme videos grow vertically from 16:9 to probably 400:9. Pretty funny though

MKV is a container, it can indeed contain multiple video, audio, and subtitle tracks.

That said I've never really seen what you describe in the wild.

Is the 1080p mode just hiding black bars present in the 1200p stream? Could be a stupid gimmick to get people to choose a particular uploader's torrents.

[–] everett@lemmy.ml 2 points 20 hours ago

Not sure, but maybe "1080p" describes the approximate level of video quality ("full HD") while 1200 is the actual vertical resolution ("full HD but taller") due to the video having a non-16:9 aspect ratio?
