Free open source programs support MKV and every other codec Adobe doesn't support. This is pure proof that there isn't any technical limitation with the program and is just adobe being pure greedy. I really would like MKV support back because recording in .MP4 is very bad and most of the time has horrible consequences. MP4 wasn't made for recording, just playing back a.k.a. encoding. Until something happens, I will be quiting adobe products for the time being. I have been using a free open source editor called Shotcut and is basically adobe premiere but you don't have to worry about what formats it supports for importing because it pretty much supports them all. I hate when companies choose greed over customer service.

Almost 6 months later and still nothing... as if adding again the removed MKV support was something incredibly hard and complicated. (－‸ლ)

I see it's being worked on now but just adding another comment and vote to get this done. Nothing more annoying than being able to open a file in VLC but not in professional editing software that costs this much.

Reading the backstory of how the feature used to be there and then was removed makes it doubly infuriating. I remember using it before and it not being a problem, try again today and all of a sudden it's an issue. And given that it's the second most upvoted thing here, a lot of people seem to agree.

@Scott Fuller - There's also a cheaper alternative that's very similar to Photoshop. It's called Affinity Photo. I've completely abandoned ALL Adobe apps at this point.

At this point I've given up and went to a black magic resolution that actually does MKV. Will be reducing my Adobe subscription from 'all Adobe products' to just Photoshop at this point.

Ring me when you finally get MKV support and I'll start giving you my money again.

A standard format for anyone recording and using OBS Studio - can't believe you can't import it.

It's not like this is the first time people have asked for this to be back and it was dropped.

Adobe is being silly. I'm running Premiere CC 2022. It refuses a MKV file but if I merely change the file's extension, without (!) remuxing into a different container format, Premiere accepts it! I couldn't believe it.
The support for MKV is clearly there, they just don't want to admit it.
We're using codecs that Adobe has supported for over a decade. Codec support is not the issue here. Supporting this container is.

Sure you're right. Another issue is that you might get .MKV support but not the specific audio or video codec you have in your .MKV, so you also need to open separate UserVoice request for each codec you need behind the MKV container

Having plugins is one thing, and there are a number of convertors that can provide workarounds. But these all waste an inordinate amount of time and resources that having the format as native would help avert.

Even having it convert natively would prevent having to switch apps, which might allow Premiere/AE/etc. to remain open on lower-resource systems, and it would also at least give the idea that the time is more productively spent in a single app.

EDIT: Really, REALLY looking forward to this as a potential future feature.

Just realizing this today. A lot of software/screen recorder programs use mkv by default (looking at you, OBS). Looks like its being worked on but yeah, absolutely agree that mkv support should be a top priority... preferably above adding new features & UI tweaks.

EDIT/UPDATE: Okay apparently I'm a fool. For anyone else using OBS, it actually comes with its own remux tool to convert your MKVs to MP4s extremely quickly without quality loss.
File > Remux Recordings - then pick your source & destination.

Maybe a good way to remux even if your files weren't generated in OBS, but I haven't tested.

This is crazy, why do I need to download handbrake and .net environment to work with a bog standard video codec? Why am I paying so much for this software?

Had I known it was removed I would've waited to renew my subscription; unbelievable; what was wrong with leaving mkv unwrapping in the software suite? It's the best multimedia container format in my opinion; ffv1 in mkv has become the standard for archival houses and it's about **** time Adobe stops blocking it for no reason. BM DaVinci Resolve has no problem with mkv. It's open source FFS.

I think half the requests in here are people just begging for features to return that were unceremoniously removed 4 years ago to, you know, improve user experience.

+1

It's somewhere strange... We are not talking here about a new feature, but about bringing back a previous feature deliberately removed by Adobe, and we are all excited, almost ecstatic... Imagine if... No, don't... ;-)

Well, it only took three years from the first message on here to support "being investigated". (Let's not think about how MKV was already supported, and then removed, because...reasons.).

Now, shock of all shocks, we're seeing a UserVoice update in the blisteringly fast time of only eleven months?

This totally makes the monthly subscription worth it!

Awesome thank you Fergus for letting us know! Please keep us updated on progress. I will resubscribe to Adobe once mkv is restored.

This is great news!

Finally.
