Have you tried changing the compatibility to other proton versions?
Mine works fine with Proton 8 and 9 beta.

Every BlazBlue has these story modes, but Centralfiction is different because it has only one story and is linear, instead of having multiple stories and bad endings (Also no Dr. Litchi extras).

proton 8 is the default right now, and this is where that's happening. I even already tried experimental and same thing.

The anime cutscenes not working correctly on Deck are why the game is listed as Unsupported.
The Calamity Trigger Reconstruction cutscenes stutter and have horrible desync, and the Continuum Shift cutscenes won't play at all (they just display color bar tests: https://en.wikipedia.org/wiki/SMPTE_color_bars).
I've got no idea if any specific Proton version or other setting can fix them, I personally just kept my phone nearby while playing so I could Youtube the cutscenes as I reached them (there's not very many of them, and ~90% of them are clumped into Calamity Reconstruction & the True Ending).



Also, each Blazblue has a different story mode. They're all part of a larger overarching plot, and they all play the same (visual novels with occasional fights), but each game's actual story content is distinct/each one is a sequel that continues from where the previous game's story left off.
Some of the games include story recaps of the previous games, but those always cut out a -lot- of the character development that you'd get from playing each game in full, seeing all of the Bad & Joke endings, etc.

The order is Calamity Trigger, Continuum Shift, ChronoPhantasma, CentralFiction.
Continuum & Chrono both have "Extend" versions that add more story content (the PC versions of both are the Extend versions, but on console you have to be careful about which version you buy, as the Extend story content -is not- sold as DLC for the non-Extend versions).

Also, Calamity Trigger on PC has an unfixable bug where the story mode has -no- background music, so I recommend getting that one on console if you wanted to experience the full story.
IMO it's worth actually playing its story mode rather than just settling for Continuum's recap of it, as CT Reconstruction is pretty much -only- the True Ending route of that game with a small handful of new scenes added.

I only have coninuum shift extend, and won't be getting anything else if it doesn't work. And I don't own any consoles. To comment on your comment on proton versions, it doesn't make a difference. I tried various proton versions and none of them make the video cutscenes work. I rather not watch any youtube cutscenes, because at that point, I'll just watch the whole thing on youtube, the console versions.

I'm still getting the gist of the story without the video cutscenes. I get where it's going. When I go through the story mode of this version, I think that's that.

Gotcha. As a heads up, Chronophastasma -is- Deck Verified, so if the main worry putting you off from trying the other games is that they might also have cutscene issues, that should be the one entry that runs totally fine on Deck

For anyone who still needs help with this, I found a fix for the cutscenes, with no audio delay stuttering, issues, etc.
you have to disable the audio converter while using an older GE Proton that can play the videos:

Run GE-Proton 8-16 (this is what i'm using and everything works great~)

you must add this launch option:
GST_PLUGIN_FEATURE_RANK=protonaudioconverterbin:NONE %command%

enjoy~

Unfortunately all that is a real pain in the ass on a steam deck. Besides, the stutter isn't the only problem. Some videos just show color bars.

I don't see videos with color bars on this GE Proton version, it runs near perfect except for the audio issues, which is fixed with this launch option.

A bit of an over-exaggeration to call it a "pain in the ass", you only need to install GE 8-16 using ProtonUp-Qt (easily found on discover store), enable it, then copy paste that launch options line that I provided and it's all done.

It's a few clicks and a copy/paste.

Anyway that's a solution I found. For others who are able to follow these simple instructions, enjoy~

I hate being right so often, but I tried your suggestion and there is no sound in the offending videos. Now they all play, but it's moot if there is no sound.

And no, I'm not very interested in excuses or explanations. The bottom line is, it's all flaky, and there is a reason proton-ge is not official.

Doesn't matter if some other version in the list works. Your suggestion didn't work, and the reason why it didn't work for me is the relevant bit here. You obviously have some other configuration or other h4x going on there, or some other change in the game environment causes it. And if that's the case, any setup that works not will probably stop working later.

All this is what I mean when I say it's a pain. I'm not going to bother with it any more.
