MKV is a needed format in my workplace.

I totally agree with this request. I edit YouTube live-streamed content for clients and they almost all use .mkv files. It is a very long-winded process to convert to H264 / MP4.
Please bring back MKV support.

I have several projects made using mkv files. please bring back the support for the format

Please bring back mkv support or provide a method to convert the mkv files into a supported file type. I have a lot of historic files in this format I wish to still be able to use.

Importing mkv is not the main thing. Exporting mkv provides ample opportunities. The lack of mkv export is sad. For example, the ability to embed stereopair tags! Sadness.

It is extremely annoying that Premiere does not handle this seemingly trivial feature.

I'm not sure if it's been posted yet but there is a quick work around.

Just pull out the tracks from the MKV.

Get MKVToolNix which you should probably have anyway as it's the best MKV manager IMO:
https://mkvtoolnix.download/downloads.html
This comes with a few command line tools and one of them is MKVextract.

Either use it straight up or get the GUI for it from here:
https://sourceforge.net/projects/gmkvextractgui/

After running extract, you will have a video file (mp4/avc/etc) and an audio file (ac3/etc)
If the file is eac3, just rename it to ac3

I have been going in circles. But as of this moment, the best solution that I have found - maybe new? Maybe not? - is to use 'Remux' in OBS under the file menu. I'm not sure if it is an OBS MKV format only thing or if you could use any MKV? My issue has been importing MKV from OBS to Premiere. This is the quickest method I've found so far.

I tried the renaming method found on YouTube etc. (change extension .mkv to .avi) but maybe it's an OBS MKV only issue it didn't work.

I've been struggling with using my Canon 600D (T3i). Recording more than 12 minutes at full res or beyond a 4GB file limit is impossible (firmware/canon BS)! I installed Magic Lantern. ML works great. It can record unlimited length in MLV RAW. However, the resolution is sacrificed to compensate for the camera's slow systems (Sensor to processor to SD card bottleneck) and, of course, Premiere doesn't like MLV files. A one and a half-hour recording were 30 files totaling 118GB. BUT!

I am now using OBS to record from the camera over USB. Canon has a 'Webcam' driver for most cameras and thus OBS can record at full res, 24fps into mkv. I remux it and BAM!

I sincerely hope this helps at least one person.

Please bring it back
I deal with a lot of MKV content,
especially with OBS Studio

Please bring it back. I deal with a lot of MKV content, especially with OBS Studio

Please, bring back support for MKV, I have many projects that uses source files in this format and I use them again in other projects, converting then to another format will be disastrous and pain taken.

Couldn't believe it when I fired up ME to discover that MKV import was unsupported

Severely limit's the usefulness of the app in a Broadcast environment

Can anyone share some .MKV files they would like to import into Premiere Pro ?

Unfortunately OBS produces VFR files so it will be buggy anyway

Me too.
I don't need MKV encoding capability, which you never supported (and I never needed!), but please bring back the MKV decoding capability, which had been supported before and is still needed to import the default livestream recording format from OBS in particular into Adobe Premiere.
I haven't had to do an "ingest" step (which is what this forced file conversion is like) since I used a competitor's NLE software a long time ago.

Vanessa, the good news is that you can use File>Remux in OBS to convert your mkv to mp4 and then they're usable in Premiere. The conversion only takes 1 or 2 seconds.

100% agree, just recorded a long live session on OBS, absolutely gutted when I discovered that I cant edit or modify my MKV...

please reimplement this functionality, not being able to edit mkv is very irritating

Not supporting MKV is frustrating as ****, so why my upgrade?

Bring back MKV support. It is key to my work please.

It is insane MKV is no longer supported. And I hear people around the web claiming "it is a niche format". It is NOT niche and is WIDELY used in all sorts of places on the Internet. In fact, I'd say it's probably the most common container for web-downloaded media. Insane. Adding a tremendous amount of added work on the user's end for no clear reason and removing it unannounced. Terrible decision. If there were any application half as good I would already be gone.
For Adobe to just remove it and say "Sorry, you can't have this anymore. We never REALLY supported it" is asinine. Just put it back in. Whatever reason you really removed it probably isn't very good. Use your billions of dollars and fix it.
