Kdenlive - preparing for the april release

We have been working hard over the last 4 months to prepare Kdenlive 16.04, that will be released with KDE Applications around the 20th of april. This release will brings many stability and usability improvements as well as dozens of new features. We are now entering feature freeze and will concentrate on fixing as many bugs as possible for the release.

New features in this release include:

  • Audio level meter integrated in monitor
  • Split view to compare an effect in timeline against original clip
  • Increase/decrease speed of a clip now also affects its audio
  • New Library feature allowing you to copy / paste sequences between projects
  • Improved titler allowing gradients and shadows

We will try to post some details soon about how to install the latest development version for those of you who want to help us test, debug and prepare this new version.

Meet us

This post is also an occasion to remind you that we will hold our 4th Kdenlive Café on IRC this friday, the 25th of March 2016 at 11am (CET time).

This will be another occasion for developers and users to meet, on freenode.net #kdenlive channel.

We hope to meet some of you on that occasion!

Kdenlive's sprint report

Last week-end, Vincent and me met in Lausanne for a Kdenlive sprint. One of our goal was to merge Gurjot Singh Bhatti's GSoC work on curves for keyframes. This was more work than expected and we spent many hours trying fix the curves and make keyframes behave correctly. Not much time was left for sleep, but we still managed to get outside to make a group (!) picture in the woods above Lausanne.



The code is working and in git master but cannot be used yet - we want to make sure older projects convert properly to the new keyframe system before enabling it - hopefully in less than a week. Below is a small demo of the feature:



Currently, only 1 dimension parameters are supported, but we hope to extend this to the transitions for the 16.04 release, allowing to move and resize the video using smooth interpolation instead of the current linear way.

During our meeting, we also discussed several UI changes that were initiated at Randa 2015, and hope to make some progress on that for the april release.

Next friday, the 12th of february (at 11am CET time), the 3rd Kdenlive café will be an occasion to discuss and exchange about Kdenlive's developments and community.

Kdenlive: Café, Sprint and More

So following our poll, the next Kdenlive Café will happen on the following days:

Kdenlive Café #3: Friday, 12th of February, 11am (CET time)
Kdenlive Café #4: Friday, 25th of March, 11am (CET time)

This will be another occasion for developers and users to meet, on freenode.net #kdenlive channel.
The other Kdenlive events are a Kdenlive coding sprint this week-end in Lausanne (Switzerland) where our small team will amongst other challenges try to merge the "curves in keyframes" feature.

And for the pleasure, here is a screenshot of Kdenlive's clip monitor where you can see several of the new features that are currently being worked on for the 16.04 release. The monitor looks a bit cluttered like this but it's just for the demo - everything is configurable.

You can see here:

  • New audio meter widget
  • Overlay of audio waveform at the bottom of the screen
  • Safe zone
  • On monitor toolbar allowing to zoom, switch fullscreen, seek to next marker, etc

More news will come this week-end from our coding sprint!

Next Kdenlive Cafés

We want to continue the great experience we had with the Kdenlive café, a
two hour informal meeting on irc.freenode.net in channel #kdenlive.

This is an opportunity for Kdenlive developers and users to exchange ideas, talk about how we want to see the Kdenlive project evolve and also discuss how you can help us on that way!

As was done last time, we will select dates and times for the next
two Cafés, so please add yourself to this date selection tool
https://dudle.inf.tu-dresden.de/Kdenlivecafe3and4.

On Sunday, the 24th of January 2016 we will close the date selection and
announce the third and fourth Café here, on kdenlive.org and on the
Kdenlive mailing list.

The reference timezone is Central European Timezone (UTC+1).

Hope to see you there!

Kdenlive 15.12.1 released

The latest release of Kdenlive brings many bugfixes to the 15.12.0 version. More than 20 issues were fixed and we encourage all users to upgrade. You can find more details about the fixed issues in our information page.

Despite our lack of communication, the project is really active these days, with many new exciting features added to the master branch that will be released as Kdenlive 16.04.0. We will also make a small Kdenlive coding sprint at the end of this month!

Tomorrow morning, the second Kdenlive Café will happen at 10h00 UTC (11h00 CET), where users and developers can exchange.

If you like Kdenlive and want to support, don't hesitate to talk and blog about it, test it, report bugs, or meet us for a chat in the café.

You can also show your love by donating to the KDE project. The KDE community and project is supporting Kdenlive in many ways, by providing libraries, advices, organizing meetings, providing all the infrastructure and much more, allowing us to improve Kdenlive (almost) everyday!

And the date winners are: Kdenlive Café #1 and #2

So you decided and I picked ;-). The first Kdenlive Café will happen:
- on the 22nd of December 2015 at 13.00h CET (UTC+1)

in #kdenlive on freenode.net. Occasional notes will happen in notes.kde.org and shared afterwards here.

The second Kdenlive Café will happen:
- on the 15th of January 2016 at 11.00h CET (UTC+1)

See you there and happy christmas time everybody.

Kdenlive 15.12, what to expect


We have been working hard over the past months to improve stability, polish the interface and continue our big code cleanup. Kdenlive 15.12.0 will be released next week, and here are some of the changes you will get with this new version:

New Features

We managed to add a few nice features. here are a few of them:

  • Timeline effects and Bin effects can be temporarily disabled and re-enabled in 2 clicks
  • A basic implementation of a copy / paste feature has been added, which allows you to save a part of your timeline and import it later inside another project with all effects and transitions being editable
  • Track transparency: a simple click allows you to enable / disable transparency for a given track
  • Icons now automatically adapt their color scheme (light or dark) to the UI theme
  • More infos on the features should hopefully be published soon...

General Workflow Improvements

We did several small but nice changes to improve the workflow. Several context menus and buttons have been reviewed and changed to make the most useful features easier to find.
You can also now drag an effect in the clip monitor to add it to the selected clip. Or define favorite effects that will be available from a quick pull down menu in the main toolbar... just to name a few of the changes.

Stability

We fixed many crashes and timeline corruption problems, so we hope you will enjoy working with this version.

Testing

Vincent Pinon started work on packages for Kdenlive's development version so that we can get more feedback before releasing a version.

Team and Events

As previously said, the Randa Meeting really helped the Kdenlive development, and we also hope to organize a small Kdenlive coding sprint in the first months of 2016.
Mario Fux stepped in to organize a Kdenlive Café which will be a great opportunity to exchange about the present and future of Kdenlive.

And as usual, several very motivated users really helped us improving Kdenlive by reporting issues, following and testing the fixes, proposing ideas, features and patches on the bugtracker, so a big thanks to them.

Kdenlive Café #1 and #2 - Date selections

We would like to try something new for the Kdenlive community: Kdenlive Cafés. These are one to two hour informal meetings on irc.freenode.net in channel #kdenlive. We might select certain topics for these Cafés but normally you can just chat about recent things in Kdenlive development, ask questions to developers and other users and talk about the progress of this great and free non-linear video editor.

So to select the dates and times for the first two Cafés please add yourself to this date selection tool. On Sunday, the 13th of December 2015 we will close the date selection and announce the first Café here, in the forum and on the Kdenlive mailing list.

UPDATE: The timezone would be Central European Timezone - UTC+1.

Kdenlive 15.12 knocking on the door... test it easily before release!

Hello,

We've had much work on 15.8 series, with its 3 monthly bugfix to repair the breaks from the new monitor backend & timeline rewrite... should be acceptable now :)
For few weeks now we're having fun integrating few new features, inspired from our usability review, that should make users' life easier?

I won't say much more in this post, my topic here is to announce that application bundles are available again!
These prebuilt archives are now hosted on KDE infrastructure, and contain the latest code (files generously prepared by MLT dev are still KDE4 version, and hosted on a private space)...
Please note that to avoid any legal threat on KDE servers, I had to remove all potentially software-patent-covered encoders from FFmpeg builds, in any case you should be happy to support free formats ;)

That's not all folks: for *ubuntu users, I'm also setting up a new PPA to test the latest Kdenlive without affecting the rest of your system.

All this is for the moment manually triggered, so maybe not updated very regularly... my next goal is to automate all this so that both get reliable sources.

Enjoy & don't get too angry with remaining bugs :)

Kdenlive at Randa meetings - first report

We arrived here on wednesday, and started discussions about our plans in the train. Here is a short resume of what happened during these first days:

We decided to work on bug tracking during the first day, since the Kdenlive 15.08.1 release was imminent. We fixed quite a few bugs that will improve stability of the 15.08 branch.

The second important goal was to take advantage of having so many great people around us to improve Kdenlive. So we had contacts in these domains:

Mission statement:

We started the work on our "Mission Statement" to better define which users / jobs Kdenlive is designed for. This will help us to focus on important tasks for our target audience. We are in contact with people from the VDG (KDE's Visual Design Group) to get feedback on that process.

Ui design and workflow:



We had a session with people from the VDG (KDE's Visual Design Group) to review Kdenlive. We also had the chance of having a user of professional video software who had never seen Kdenlive so he was the perfect test subject for our UI review session. We wrote a wiki page on the ideas that came out of this. We encourage you to visit that page and give us feedback (a few issues were already reported on the bugtracker). As time permits, we will try to implement these ideas to improve the workflow.

Bugfixing:

There are a few issues/crashes in Kdenlive related to Qt5/KF5 bugs, and we made some contacts to get some help on this.

Next features:

We discussed some of the features we want to integrate for the 15.12 release, and other long term goals.

The feature we would like to integrate for the december release are: merge the animation feature from GSoC, same track transition (eg. overlapping 2 clips to crossfade), and a way to copy/paste between projects.
