From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux video editing and Kdenlive tips and tricks for a returning user? (lemm.ee)

Just recently switched back to Linux after more than a decade away. (I'm currently running Mint Cinnamon if anyone is curious) On Windows I was using the free version of Davinci Resolve for all of my video editing. I quickly discovered that the free version of Resolve for Linux doesn't support H.264/H.265 so after trying every Linux video editor I could find (even Blender) I've settled on using Kdenlive. I've been having a good time getting everything dialed in and learning Kdenlive. I was able to get hardware acceleration working with my Nvidia GPU, and I really appreciated that it could natively utilize the proxy clips that my DJI Action 3 generates when recording. I've been reading all kinds of tips and tricks articles but most of it is just basic stuff. Anyone using Kdenlive have more advanced tips to share? Particularly anything around title generation and animation as I've found Kdenlive's system to be a little clunky. Let's talk!

Oh, I see what you mean about the Glaxnimate Flatpak. I just tried it out.

You can get it to work, but it's a bit of a hack. You first need to create a script containing:

#!/bin/sh
/usr/bin/flatpak run org.mattbas.Glaxnimate $@

Let's call it glax or something like that. Then make it executable:

chmod +x glax

Then in Kdenlive, go to Settings -> Configure Kdenlive -> Environment -> Standard Applications, change the one for editing animation to point to that script. Should work now. At least, it did for me!

And yeah, shame about the audio processing.

ahh, that makes sense. I'll give it a go.

EDIT: Hmm, didn't seem to work for me. I created the script and made it executable then put the path to the script in Kdenlive's settings. I can right-click in the project bin and click "create animation" which gives me a .JSON file but I see no way to edit it. Double-clicking it just shows me its properties and right-clicking and selecting "edit clip" does nothing. Interestingly if I execute the script from terminal it starts Glaxnimate as expected. I also went ahead and created a similar script for Pinta as my image editor since I'm also running the Flatpak version of that and had the same result as Glaxnimate when trying to edit images. I also entered the path for Audacity as my audio editor, but it's installed as a system package so I pointed Kdenlive directly to the binary and got the same result when trying to edit audio files. Maybe I'm just not understanding this, or I have something setup wrong in Kdenlive... Any ideas?

Hmm, no sorry. All I can think of is that maybe Kdenlive itself is a flatpak version in which case it wouldn't be allowed to run external programs like Glaxnimate (or Pinta). I guess in that case it requires some magic with Flatpak overrides.

Nailed it. I didn't even think to check that... I'll have to see if I can find a workaround. Thanks!

Yeah, tricky! You might be able to do something similar to getting native messaging extensions to work on Flatpakked Firefox as described here: https://bugzilla.mozilla.org/show_bug.cgi?id=1621763#c5
