Thanks for the report.
I can try to see if i am able to get a apitrace of the issue here later.
I have bisected this to be either
https://github.com/doitsujin/dxvk/commit/2bf9f298af776a0ac44f9f53b27956ae3da03b99
or
https://github.com/doitsujin/dxvk/commit/9fe1b9d03ff89faeb210a577baad4aee0e49fedb
I can't test the first one directly as the game will crash when the videos are supposed to start. The second one is the commit right after and have the broken videos
Managed to trace the game but the issue just gets baked into it so i'm uploading a working made with 1.7 and a broken made with 1.7.1.

The issue here seems to be how the data for the format converter is packed. The format is YUY2.
This appears to work again when changing https://github.com/doitsujin/dxvk/blob/1482715fd1f1c310cd183d61f9039ff11425eee4/src/d3d9/d3d9_format.cpp#L196
to VK_FORMAT_G8B8G8R8_422_UNORM, but i don't know if that is correct so just posting it here on the issue so it doesn't get lost before it's looked at.
Same for https://github.com/doitsujin/dxvk/issues/3189
just tested with Proton experimental, the cinematics played nicely, bravo!

Jade Empire: Special Edition no longer plays videos correctly. This can be easily seen by just launching the game and looking at the videos that play before the main menu. See screenshots posted by @legluondunet on the github issue where this was first reported: https://github.com/ValveSoftware/Proton/issues/2112#issuecomment-1365141049

Software information
Jade Empire: Special Edition (7110)

My builds weren't completing properly, so I was unable to narrow it down further.
