I have MLT installed. I have tried with an Appimage too. All fail.

I have installed AUR (en) - blackmagic-raw-sdk

I use Kdenlive 23.08 and MLT 7.18

Any help?

I think ffmpeg can’t read braw files (at least couldn’t find any info about it).

I would say convert the files to another format?

3

Seems a bit complicated for me. But I am still wondering if Kdenlive may support this format directly or not.

4

But I am still wondering if Kdenlive may support this format directly or not.

Kdenlive uses ffmpeg to encode and decode media. As a result, Kdenlive supports whatever ffmpeg supports and that’s it. As mentioned in the first comment, ffmpeg doesn’t support BRaw.

So you would have to ask ffmpeg devs to support it, not Kdenlive. However, I’m assuming they can’t include it directly in ffmpeg because of licensing issues unless they write their own decoder from scratch that doesn’t rely on the official SDK (I’m not sure on this though). So don’t get your hopes up. Using AkBKukU’s script for conversion, or, if possible, recording in a different format to begin with is going to be your best bet for the foreseeable future.

5

Or even better, ask Blackmagic Design to stop these proprietary shenanigans in 2023.

So is the format proprietary? I cannot find any info about this. And yes I agree this is BS. Unfortunately someone filmed a presentation of mine in this format and I was provided with these terrible file formats…that I cannot edit in Linux except if I use the proprietary Davinci Resolve. I am angry at this.

7

Well since it is just a talk, convert the files as I mentioned in an earlier comment.
