Now in beta: Support for H.264 in MKV

[Fergus H]

Hi all,

The latest beta of Premiere Pro and Media Encoder now include support for H.264 in MKV. Our support is particularly focused on customers using MKV files from OBS (Open Broadcaster Software). We support AAC and PCM audio. 

We’d love to get your feedback on this new feature. 

Regards,

Fergus

Thanks for the work, and for posting. I think a lot of users would appreciate this ....

This makes my life easier. Thanks!

If support for multiple audio tracks is not added, I'll have to take this back. MKV support without multiple tracks has no value for me.

Great! Changing the container from mkv to mp4 before importing was not hard - but i am glad to get rid of this step! Thanks!

Hi Fergus,

This is good news, I appreciate the decision of Adobe to support mkv once again.

Hi Fergus,

I have tested the PP Beta and the first thing I noticed is that it does not load multiple audio tracks, a feature that I use with OBS to separate multiple sources.  Will this be included?

Thanks!

[Tom Nord]

Sorry about that. In discussing with our developer it actually looks like this might be a bit of work. I've put in the request and will work with the team to determine where this might fit. 

[MauroCL]

Hi Tom,

Thank for the feedback. It will be a bummer not to be able to import the tracks, as this feature is key to ensure a right audio balance and quality in post, rather than trying to nail it during production by determining when a source is needed or not at specific segments. 

Looking forward to have a positive feedback.

Regards,

Mauro

I use this same workflow, recording my microphone and the desktop sound on different audio tracks. If this is not supported, the MKV support has no value for me, unfortunately.

[Tom Nord]

Understood. Thank you for the feedback.

We Export need H.264 and H.265 in the MXF container, please. It's a broadcast standard and the only good way to do embedded captions. Should not be that hard. 

[Tom Nord]

We currently support a wide range of MXF files including ones that used H.264 and HEVC. Is there a particular MXF format you need that is not currently available? 

[johnpooley3]

Wow I obviously didn't proofread my comment

Nonetheless; 

- There are no HEVC MXF OP1A export options

- The bitrate is not customizable on any H.264 MXF OP1A options

Just give us the MainConcept encoders in MXF, please

I just tried dropping an mkv into my project in 25.2.0 BETA but it says not supported.

[R Neil Haugen]

Created by what?

[Tom Nord]

The MKV must be H.264 - other codecs are not supported at this time. Also please make sure you are on the latest 25.2 Beta build.

I am using a normal Premiere Pro install from Creative Cloud. If I go and install Beta version, would it have any impact on my existing projects? will I lose any feature? is there a prerequisite that I must know before using beta version? also, I don't see a beta version in my CC app.

[R Neil Haugen]

The beta versions install completely separately from the 'shipping' versions. Always.

They are in the left-side tab section of the CC app, under "beta versions".

And when the shipping and beta are the same build series, as they are at the moment, you can open a project in the beta, close, and open in the shipping version.

Hi Neil,

Thanks for the info. However, I am still unable to open a project in Beta mode. I am a noob with PP beta. How do I begin to open a project in beta mode?

[R Neil Haugen]

You install the beta app from the CC Desktop app. It installs separately as designed. Then you simply open that app.

Hi Neil,

I can't see a beta app in my CC. It only shows an AR app under 'Beta' tab of CC. I had attached a pic in my last post.
