Photoshop doesn't support MKV

Indeed, I "demoted" your previous answer from a best to a regular answer.

@ZBalling Actually, Davinci Resolve 18 indeed DOES support MKV files. It was one of my pet peeves in previous versions, because I record tutorials with OBS, and I had to transcode those for use in Resolve.

Much to my (pleasant) surprise when I upgraded to V18 I could just drag and drop those into my new projects. 

It saves me a lot of time. The MKV files are good enough for the purpose they serve.

Sorry, while it's nice to be appreciated, my answer was in NO WAY the correct answer. I was simply clarifying the nature of the MKV "Container". All we are asking is for Adobe to provide the ability to ingest an MKV video into the project and we'll take it from there.

Literally does not understand that mkv is not a format, it is a container, and has nothing to do with hevc or avc.

I thought I had posted this earlier, but I don't see it. This is the Adobe Blog post from Eric Philpott in 2019:

https://blog.adobe.com/en/publish/2019/05/03/changes-to-mkv-format-support-in-premiere-pro-and-adobe-media-encoder

"We wanted to let you know that we will be removing support for the MKV file format in the next updates of Adobe Premiere Pro and Adobe Media Encoder.

"Our previous MKV file format was limited to decoding for playback. We have never offered support for encoding MKV, and overall usage of this format has been very low.

"Users who need access to MKV files can consider third-party utilities. For rendering out video content for online platforms we encourage our users to take advantage of existing output options, such as H.264 and HEVC formats, which are widely used and supported."

Given that Adobe dropped support for that format from their video editor (Premiere Pro) in 2019, I would not hold my breath for support in their image editor (Photoshop) which has limited video functionality.

Davinci does not support it either, cause it is bad, it cannot even preserve 24/1.001 frame rate.

Thank you for the information, I was not aware of that excellent case!

as I said, there are also legitimate use cases for MKV.
