I'm a bit at a loss how to locate the issue. Any help is appreciated :)

Hi guys. Thanks for your great work. I am coming from a FCP and Premiere experience. I want to know if there is anything special about the way you chose shortkeys. It is very confusing for me for example when I want to go to the previous or next cut in timeline. In both FCP and Premiere, the Up Arrow key is for jumping to previous and Down Arrow key for jumping to the next cut. While here, it is exactly opposite.

Is there anything special here?

Isn't it better to follow what is mostly accepted as the norm?

Hello,

I've seen in the roadmap that there is interest in integrating Natron in Flowblade. I think it's a great idea and there are many people waiting for Natron integration inside some NLE to act like a kind of Nuke Studio. So maybe rather than having some kind of an headless control of Natron inside Flowblade (like a title generator) it would be way more useful to let user create custom workflows and associate some application + some python scripts to a clip in the timeline. Maybe it could be like applying an effect to a clip. Then it would be great to be able to open Natron from the timeline , apply some effects to the shot and render it outside or inside Flowblade. Then having the result inside the Flowblade timeline. The best would be to be able to lauch some scripts when opening a Natron project , and/or at render time. That way it open the door to great customisation for integration in some professional open-source pipeline. If this system is generic enough , it may allow to plug other applications than Natron, like Blender or other commercial application, or for instance some imagemagick process on a image sequence.
I've looked into several open-source NLE and none of them allow this kind of workflow that is very useful for animation or VFX work. Only blender with the VSE is able to do some scripting stuff and let the user link any applications to some shots. If you think that idea is useful I can make a real proposal and better design on how this could work.

Please include the following information.

1. Flowblade version (Help->About): 2.2.0
2. MLT version (Help->Runtime Environment): 6.14.0
3. Your distribution (Ubuntu, Debian, Mint etc.): Manjaro
4. If possible, try to provide step-by-step instructions on how to reproduce the issue. From developer point of view this is the easieast way to understand what is happening.:

• I have a wav file created with audacity.
• I play it outside flowblade and sounds at full volume
• i open my project, add it and the sound volume drops
• i play it in the editor tab and the volume changes weirdly
• i create another project, add it and i get the same result
• i render the file, open it in audacity and the volume wave is about 25% of its "capacity"
• i do it in Olive and sound normally (it also uses mlt)

I dont know what to do and i dont know how it happened. i deleted the flowflade .config dir = same result. i checked the mixer values = all 100%. I reinstalled mlt, same result. I reinstalled flowblade, same result! i tried flatpak version, same result! i tried different files and formats, same result!

I need to upload my video today... :(

On Manjaro (unstable branch) and apparently Archlinux in general, the update to mlt 6.8.0 (and also python2 to 2.7.15 seems to have broken flowblade. More details on the segfault here

The main window is taller than my desktop height and it resists any attempts to make it shorter. This makes Flowblade really annoying to use on a 1024x768 desktop.

I can't even resize the inside of the window. It looks like there's a drag bar that promises to let me make the tracks taller and the player window shorter, but when I grab it, it doesn't move. Also, I tried to make a video track "Large Height" and it complained that there isn't enough vertical height. Well, there would be tons of it if I could make the player window use less of it and give more of it to the tracks and there would be even more height available if the track section could be in a vertically scrolled window of it's own.

TL;DR 3 height problems:

1. The whole main window is too tall and cannot be made shorter
2. The track section isn't tall enough and cannot be made taller
3. The track section doesn't scroll vertically when there isn't enough height.

I open this issue report to find the reason why Flowblade crash on many distros. As it was reported here : https://github.com/jliljebl/flowblade/issues/445 the problem seems to touch also Ubuntu (17.04 or 17.10) (I use many machines affected by the same problem) I use Flowblade version 1.14. On some machines it's libmlt 6.4.1 or 6.5.0 (this comes for the kdenlive repository) (Not every machine have kdenlive repository installed but it crash anyway) On all those machines, it's X11 (and not Wayland). Can we identify if the problem comes from GTK or MLT (SDL vs SDL2) ? As you suggest it in the 445 issue, I will try to put some print in app.py to check where this problem come from and I'll be back to this issue report.

Flowblade version 2.4.0.1 / Ubuntu 20.04

Currently the only render preset that seems to work entirely properly is: Lossless FFv1 (which is a workable solution in my case)

H.264 / .mp4 seems to not write any data to my output file, but when I export an MLT XML the melt command does export a H.264 encoded mp4....

Is there any debug flags I can enable to see why Flowblade renderer get's stuck, while melt does not...

Flowblade 2.2 (MLT 6.16)

I've recently gotten a Contour Design ShuttleXpress Black jog wheel, it's a hidraw device, which combined with a bit of software ( https://github.com/pmjdebruijn/shuttleevent ), can "fake" keypresses depending on the application window title.

In general it works quite nicely with increasing numbers of Ctrl+Left/Right mapped to how far the dial is rotated.

I'm noticing however, that sometimes things can go a bit unexpected depending on focus in the application.

For example when actively working with a compositor, like Affine Blend, typically the arrow keys will move the image being composited, as opposed the timeline, unless focus is moved.

And while this makes sense for keyboard+mouse workflow, it feels odd when using a jog wheel, ideally I'd like the jog wheel to always map to timeline changes.

Would you be open to adding a second set of hotkey that are analogous to left+right key, but contextually insensitive, for example ',' and '.' , so when these are pressed, it always affects only the timeline never anything else, same for Ctrl+',' or Ctrl+'.' of course :)

Here is the screencast of what I do and how it looks: https://youtu.be/IG8_nooZAHs. It is no matter whether I use MPEG-4 or MPEG-2 for proxy. The source files are AVC, 2K and 4K. I assume it's the problem with the H.264 decoder used for making proxy files, as all of the video players on my system play the same source files perfectly, but play the proxy files made with Flowblade with exactly the same artifacts in the same places.

Flowblade version is 1.12.2. I use the deb-multimedia.org build but it is not the reason as I tried the official build and the problem was there. My system is Debian Linux Stretch x64. My video card is Radeon R7 240, using the free drivers. GStreamer version is 1.10.4 (if that matters).

When trying to undo the action is not undone, this is the error displayed in Ubuntu crash log:

Traceback:

Flowblade v2.8 MLT v6.24.0 GTK v3.24.35

Linux Mint 19 Tara / MATE v1.20.1

It seems that Flowblade here crashes after adding a 4th audio track to the project (1 vid track), returning to the desktop screen... is there any crash log available?

Please include the following information.

1. Flowblade version (Help->About): 2.8 (latest source from Dec 4th 2022)
2. MLT version (Help->Runtime Environment):7.40
3. Your distribution (Ubuntu, Debian, Mint etc.): Ubuntu 22.04 LTS
4. If possible, try to provide step-by-step instructions on how to reproduce the issue. From developer point of view this is the easieast way to understand what is happening.:

Take a project saved with any previous version (I tried both 2.8.0.3 from Flatpak and Ubuntu, as well as files saved with older releases prior to 2020). Attempt to load it. Flowblade will sit there "unpickling" forever. In the cli you see:

AttributeError: Can't get attribute 'Playlist' on <module 'mlt' from '/usr/local/lib/python3.10/dist-packages/mlt/init.py'>
