Guardians of the Galaxy 1 in 4K - resolution errors

[thewallace]

I just extracted Guardians of the Galaxy 1 (4K) from disc. It went smoothly with no errors, the output was a 56gb mkv.

The video through HDMI to my Sony X900E is washed out which is a well known HDR problem. But what I found odd were the video attributes when I opened it. Instead of 3840 x 2160 the direct rip shows as 1920x1080 at only 23 fps. Any idea why MakeMKV would alter these?

Makemkv does not alter it.
Something else in your chain is probably doing live encoding.
What is your playback device and how is it streamed to there?

I just opened the mkv in Magix Vegas and it shows the same settings. I have the feeling that these settings are displaying incorrectly for some reason. I wonder if there's a way to change them at the file level without resaving it.

Noone seems to have discussed ripping the 1st episode of these movies. Maybe the encryption has a layer that's difficult to get off properly.

Mediainfo (https://mediaarea.net/en/MediaInfo) can tell you all kinds of details about your .mkv files. Point it at the file in question and see what it says.

If it's a Dolby vision title that software may be incorrectly showing the dv enchantment stream as the main info dv info would be 1080p

Solved it, the file was corrupt somehow. I ripped it to a mkv a 2nd time and resolution is correct. Probably should have tried this it before.
