So that works for whatever has been ~amd64 at this point on Jun 01, 2016 07:29, tomorrow that information might be useless again. If you list working solutions, then please include their version atoms. You should also do that in your package.keyword files unless you'd like to stay unstable ad infinitum.


Sorry for that^^ :oops:

So I will try again.

If someone use a stable Gentoo (amd64) on 3rd of June 2016 and kdenlive (16.04.01 or 15.12.3) crashes when compiled with frei0r use flag, this is my working solution:
Code:
# cat /etc/portage/package.accept_keywords/video-editing
=kde-apps/kdenlive-16.04.1 ~amd64
=media-libs/mlt-6.2.0 ~amd64
=media-video/ffmpeg-2.8.7 ~amd64
=media-plugins/frei0r-plugins-1.4 ~amd64
=sys-devel/autoconf-archive-2016.03.20-r1 ~amd64
=media-libs/opencv-3.1.0-r1 ~amd64


With frei0r use flags, you have much more effects and tools for your kdenlive:
Code:

I appear to be missing the pre-defined rendering defaults that appear in other Linux distros - eg. Web/Youtube, etc. Does anyone know how I can enable these? Currently I can't really render anything useful in Gentoo. :cry:

What do you mean by this?^^
Web/Youtube do not exist in the newest version as used to be I think. You have now WebM, MP4 or MP2 - which works everywhere now form laptops, tablets, game consoles to mobile devices. YouTube could converse anything now but as a standard preffer MP4.

What version do you use?

Hi,

If kdenlive (16.04.01 & 15.12.3) for Gentoo amd64 (stable) crashes when compiled with frei0r use flag, this is my working solution:
Code:
media-plugins/frei0r-plugins ~amd64
sys-devel/autoconf-archive ~amd64
media-libs/opencv ~amd64

Hi Xywa

I did not see this thread until asturm pointed me to it. Here
Your advice worked, but there is this cool Transition ( Affine ) that still wont show up in the list.
Did you manage to get that one working ?
I'm looking for the one used to animate text Used Here on Youtube

Code:
# vim /etc/portage/package.accept_keywords/video-editing

=media-libs/opencv-3.1.0-r4 ~amd64
#=sys-devel/autoconf-archive-2016.03.20-r1 ~amd64
=sys-devel/autoconf-archive-2016.09.16 ~amd64
#=media-plugins/frei0r-plugins-1.4 ~amd64
=media-plugins/frei0r-plugins-1.5.0 ~amd64
=kde-apps/kdenlive-16.08.1 ~amd64
=media-video/ffmpeg-2.8.8 ~amd64


Above worked, but still no Affine :cry:
Let me now if you got this working.
Thanks in advanced.

spidark - which version do you use? There is 16.08.1 in portage for ~amd64.

And could you list your:
Code:
ls /usr/share/kdenlive/effects/

I'm no developer nor whizkid, but i think the affect i'm looking for is provided by the mlt package, because it does work on my laptop, which has another Linux OS, they are using the same MLT version as in Gentoo Portage.
I'm recompiling some stuff at the moment, i'm hoping enabling the trans-code flag in this case fftw use flag wil enable affine among other effects and transitions, crossing my fingers.

Code:
[ebuild   R    ] media-libs/mlt-6.2.0-r2::gentoo  USE="ffmpeg fftw* frei0r gtk kdenlive libav* libsamplerate* lua* melt opengl qt5 rtaudio* sdl vdpau xine* xml -compressed-lumas -debug -jack -python -ruby" CPU_FLAGS_X86="mmx sse sse2" PYTHON_TARGETS="python2_7" 0 KiB


I did notice a missing directory on Gentoo.
Code:
$ grep -rl "affine" /usr/share/mlt/
/usr/share/mlt/plus/transition_affine.yml
/usr/share/mlt/plus/filter_affine.y

The Plus directory does not exist, in my case.
So i peeked into that dir

Code:
schema_version: 0.2
type: filter
identifier: affine
title: Transform
version: 1
copyright: Meltytech, LLC
creator: Charles Yates
license: LGPLv2.1
language: en
tags:
  - Video

Maybe there is an easier way :wink:
Ill let you know if this approach worked.

Sorry forgot about libav/ffmpeg thing,
I use ffmpeg, and not libav, so in my case i disabled libav

Hi Xywa,
That did the trick,
Compared to my Laptop kdenlive version, this one have major lag issues when moving the timeline marker over video and Photos.
Works like a charm over audio, but lags on video/pictures, maybe it just my system.
But affine transition showed up.
Thanks
:D

Great!
I use kdenlive for everyday job :)
Just missing slowmovideo, which for some reason stopped work for me after last system update.

Just discovered it a month ago,and it does a great Job.
I.m in no way pro,just small stuffs ,
It’s running smooth and have not crashed yet,i also managed to fix the Timeline cursor lag issue,by changing the Track compositing from High Quality to none,worked like a charm.
I checked slowmovidoe out, nice piece of software, don't know it yet :wink:

Does anyone have the "speed" effect working?
It appears on my list of effects under motion, but when selected no little window appears to give me a place to specify how I want the speed adjusted. (On you tube videos giving instructions for using the kdenlive speed effect, such a thing does appear.)

I can achieve this effect from the comand line, using ffmpeg, but having it integrated into kdenlive would be more convenient.

Other than this, I really like kdenlive and use it to do the editing and rendering of the videos that I make.

spidark - Do you use movit as hardware support of video in kdenlive?
[Settings] >> [Configure Kdenlive] >> [Playbavk] >> [use GPU processing (movit) library)

On my laptop (Nvidia Optimus) I finaly got this option, works MEGA smoothly in Clip Monitor, but when I switch into Project Monitor kdenlive crash (so I have to check the reason). This is mega streoid for kdenlive, so you could see everything smothly when running a project, and do not need to do a proxy - like in Final Cut Pro in Mac (which is also heavly optimized).

Also I see you use the newest Opencv, so I am rebuilding it now from 2.x. into 3.x :)

Wow... 8O
I had no clue of this option until now, and wow 8O
I do not have a nvidia card, but running smooth on my Hybrid Ati ( not activated) /Intel HD Graphics 4000.
I can switch to Project Manager and Clip monitor without any issues, does not crash.

When I switch off this options, I do not have any errors. Kdnlive & GPU (movit) support is still under a heavy development, but offloading CPU into GPU for video editing will be a huge step forward for linux video-editing community.

Anyway, thaks for posting your settings. Thanks to that I updated my opencv from 2.4.12-r1 (amd64) to 3.1.0-r5 (~amd64) and slowmovideo (package done by one of kdenlive developer) for Gentoo finaly works: https://forums.gentoo.org/viewtopic-t-1052022-highlight-.html

media-gfx/slowmovideo
https://gpo.zugaina.org/media-gfx/slowmovideo

Slowmovideo is free & open-source alternative to twitter (ULTRA slow motion plugin) which cost about $300.

Here is an example:
https://youtu.be/XGqybtUzySk
up to 0:08 is ordinary 50fps into 25fps, then 0.08 is slomovideo effect
or here (ultra slowmo video)

Here are my settings:

Hi Wywa,
I should be the one thanking you,It was your post that solved my issues in the first place, so thanks for that.
Slowmovideo looks great, nice and cool.
I'm not sure is works or supports Ati cards :?:

Code:
IUSE="video_cards_nvidia"


Code:
PDEPEND="video_cards_nvidia? ( media-gfx/v3d )"


But when i solve my Ati card issues, i'm going to try slowmovideo.

Thanks again.
Cheers.

It doesn't require a graphic card, so you could try it today. I have nvidia, but slowmovideo is compiled without nvidia support (just use CPU and opencv).
Code:
$ cat /etc/portage/package.use/video-editing
media-gfx/slowmovideo -video_cards_nvidia


So comile it, and let me know, if you have any problems.

I am thinking about making tutorial kdenlive videos series like this (made 5 years ago):

Kdenlive & Gentoo for beginners

So, are you ready to use on your Gentoo desktop very powerful video-editing software for linux called kdenlive? Bellow are my few informations & tips for beginners based on my experience.

If you use a stable Gentoo amd64 (as I use) you need to update few packages (to ~amd64), as in video editing & multimedia world, any new version often means better stabilizations and solved bugs, so keeping older version means crashes, problems & frustrations. The general advise on kdenlive forum is – Have a problem? Make an update to current version first…

Which packages are important?
kde-apps/kdenlive (main program)
media-libs/mlt (“melting” heart of kdenlive, installed automatically with kdenlive)
media-video/ffmpeg (kdenlive needs ffmpeg NOT libav, so if you use libav, you need to switch into ffmpeg)
media-plugins/frei0r-plugins (lots of EXTRA VIDEO effects, need to be installed separatley as is not installed automatically with kdenlive)
media-libs/ladspa-sdk (lots of EXTRA AUDIO effects, need to be installed as is not installed automatically with kdenlive – you could just add ladspa USE flag to make.conf)

To optimize for your hardware, please check USE flags for those packages: kdenlive, mlt, ffmpeg, frei0r-plugins and ladspa-sdk by eg. ‘equery u’ command and add any mising USE flags (eg. x265 frei0r vaapi vdpau ladspa...) to your make.conf file:
Code:
$ equery u mlt


In my case for 2nd October 2016 I have such package.accept_keywords set for video editing (for stable amd64 Gentoo):
Code:
# cat /etc/portage/package.accept_keywords/video-editing        
=kde-apps/kdenlive-16.08.1 ~amd64
=media-libs/mlt-6.2.0-r2 ~amd64
=media-video/ffmpeg-2.8.8 ~amd64
=media-plugins/frei0r-plugins-1.5.0 ~amd64
=media-libs/opencv-3.1.0-r5 ~amd64

With this pack above^^, for everyday work I do not have any crashes and all the effects works fine.

To check, what effect are installed for you kdenlive, use it:
Code:
$ ls /usr/share/kdenlive/effects/
 

Worth to know
Kdenlive could also use your GPU power during video-editing thanks to movit library, but it is under heavy development and not stable on every computer yet. Try this on your system: [Settings] >> [Configure Kdenlive] >> [Playback] >> [use GPU processing (movit) library].
I test it with:
Code:
=media-video/movit-1.3.2 ~amd64


I hope this mini-guide will be usefull for someone :)

Compiled
No issues so far.
Works on Intel just fine.
I also like the frames directory that it creates, you can use those frames in blender or any other program. :lol:
But it works, nice one Xywa.
Thanks.

I'd like to give a shot for this software, but how much of KDE stuff can be left out? I'd be ok with qt UI. But pulling half of the kde desktop wouldn't be nice. Especially when I'm on i3 wm 98% of the time.

Seems like wayyy too much for me. :)
But hey... I could consider running it inside a some kind of container. This would maybe allow me to install it once (with all the dependencies) and performing updates to it and its dependencies very rarely.

Is this possible? I'm running systemd on this PC so I could make use of the systemd-nspawn?

Please note that I have never used any containers, so I'm worse than noob in this.
