0001499: opening old project causes audio to be readded to video

Wed, 10 Mar 2010 09:49:00 +0100

In every instance, I found that when I separate audio, mess with it how I like, and save my project, the next time I open the project, the audio I had previously messed with is still there, but it also readds the audio from the video. So I have to separate it from every single video and delete it again. This happens every time I open the project.

0001479: Drag from Timeline to multiple Tracks (no snap-in to track)

Wed, 10 Mar 2010 08:13:44 +0100

Hello,

when I drag a a track from the project tree to the timeline, it does not snap-in to a certain track. Instead you can place it anywhere (e.g. on the boundary of track 0 and 1).

First I thought it would be an unusual feature (I am new to kdenlive), but in all tutorials it doesn't behave like this. Also after dropping, there are a lot of things that don't work, like adding transitions, delete actions and so on. t this point kdenlive is basically completely unusable to me. I guess is very messed up.

Please see the attached screenshot for an example.

0001485: Image Alpha Transparency does not work as expected

Wed, 10 Mar 2010 03:57:08 +0100

Image Alpha Transparency does not work as expected

Track 1 - png or svg image with alpha transparency
Track 2 - nothing
Track 3 - clip (video or image)

Image on track 1 has to have a composite transition to display its alpha transparency. This is wrong wrong wrong. Kdenlive should natively use the alpha transparency of the image.

And apply that over all of the clips below it, not just the immediate clip below.

In the above track description, the alpha transparency does not work because there is no clip in the track immediately below.

Alpha transparency should be applied to all tracks just as in any standard graphical program such as Gimp, Photoshop, Inkscape does with layers, allowing all layers below to show through.

This makes persistent titling (a title that spans many clips) extremely painful to implement and just plain impractical.

At the moment, I will have to resort to rendering the whole clip and then creating a new project to apply the title over the whole of the clip.

0001457: find_package(Nepomuk) should be macro_optional_find_package(Nepomuk)

Tue, 09 Mar 2010 17:28:17 +0100

Simply replace find_package(Nepomuk) with macro_optional_find_package(Nepomuk)
in src/CMakeLists.txt to gain CMake configure switch -DWITH_Nepomuk=ON or OFF
to control what is being built.

This is what we do in Gentoo's kdenlive-0.7.7 ebuild:

sed -i \
-e 's:find_package(Nepomuk):macro_optional_find_package(Nepomuk):' \
src/CMakeLists.txt

as temp. workaround.

Thanks!

0001450: Invalid transition configuration dialog

Tue, 09 Mar 2010 08:48:17 +0100

I have project with some Wipe transitions. When I open it using kdenlive in Czech language, dialog for transition editing contains other transition than my Wipe transition.

I think that this is caused by the fact that this transition name in the Czech language is very different ("Postupne zmizeni").
Using English version there is no problem. And using transition with the name same in the Czech and English there is no problem too.

The problem is same on the last version 0.7.7

0001498: SVG files: incorrect alignment for composite effect

Mon, 08 Mar 2010 22:23:51 +0100

Reproduce:
1 Get an SVG file, e.g. http://de.wikipedia.org/wiki/Datei:Bonsai-auf-Felsen-Form.svg [^]
2 Add it to kdenlive (add file).
SVG is shown centered.
Right-click on SVG file > Properties > Transparent background on.
3 Add color clip on track 1
4 Add svg clip on track 0, above color clip
Now the svg will be left-aligned whenever it is over the color clip,
but centered when there is no other clip below.

0001497: audio fade in/out do not observe "normalize" effect

Mon, 08 Mar 2010 22:03:21 +0100

See http://www.kdenlive.org/forum/volume-difference-if-normalize-and-audo-fade-inout-add-applied-both [^] for a discussion related to this problem. It seems the audio effects "fade in"/"fade out" can not be combined with "normalize" currently. At the point where "fade in"/"fade out" starts, volume always jumps whenever a "normalize" is in effect for that clip.

0001492: "3 rendered seconds are just enough"

Mon, 08 Mar 2010 14:08:52 +0100

Hi,

I create about 5 kdenlive projects and prepare their content. In the evening all of them were started to render during the night. In the morning the status of all of them was 100% complete. However, mplayer can play only first 3 seconds of the first movie. All of them renders only first 3 seconds to the file (duration of rendering is as long as it would be).

Playing melt on the generated .sh.mlt is OK.

0001490: crash on deleting a clip

Mon, 08 Mar 2010 11:53:20 +0100

I was trying to delete a clip video from a track and after using de supp key or scisors the application crash.
There is another problem link to this behaviour is that magnetisation of track don't work anymore (they do with fedora 11)
when I drag a clip from the project monitor window to the timeline it does not snap-in. In fact you can place it anywhere but kdenlive place it invisibly after the last clip and it's imposible to put a transition nor effect on it.
The behavior is the same with an old project mounted without any problem on fedora 11.

0001496: "Delete" should delete effect when an effect is selected

Mon, 08 Mar 2010 11:48:31 +0100

At the moment, if you add an effect to an clip, you can't delete it using the keyboard "delete" key. While changing the effect parameters, hitting delete should delete the effect and not the clip.

I regularly delete clips accidentally because of that.

0001495: Add "reverse play" to clips

Mon, 08 Mar 2010 11:36:13 +0100

It would be very valuable to be able to reverse the playing of clips.

I can see two possible solutions :
- Enable negative speeds in the speed effect
- Add a "reverse" video effect

Having both would actually be good as well !

0000334: Audio Track controls

Mon, 08 Mar 2010 11:32:06 +0100

You should have a levels/volume adjustment for every audio channel in an audio track (ie: level control for left and right, and for 5.1, etc etc).

You should also have a pan-to-master control, or better yet, a send-to-master control.

So that say, you have Audio Track 2, and it's mono, single channel (master youre sending it to could be stereo, or 5.1 etc), you want to pan/send the left channel to the master left channel 70%, and right 30%.

0001494: Request : automatically split audio and video clips

Mon, 08 Mar 2010 11:26:55 +0100

It would be useful to have an option to automatically split audio and video when draggin a clip onto the timeline.

When doing serious audio/video editing a user will most likely separate audio from video manually for each clip, and while it's easy to do it can be quite tedious, and it's easy to forget a video clip has an audio track.

0001493: Can't combine audio volume and fade-out

Mon, 08 Mar 2010 11:10:42 +0100

After changing the volume of a clip, if you add an audio transition the volume change isn't taken into account (it goes up to 100% at the end of a fade-in and start at 100% for fade-out).

Fades have to be done manually with the keyframble volume effect, which isn't very practicle if you have a lot of editing to do.

0001439: rendering crashed

Mon, 08 Mar 2010 02:57:08 +0100

I work with fedora core 10 64b. I have compiled the lastest version of kdenlive and mlt.
Kdenlive work fine, but when I rendering a clip I always get the same error:
rendering of /user/kdenlive/file.mp4 aborted, resulting video will probably be corrupted
I have tried with a lot of clips and formats, and always get the same issue.

Any solution for that??

0001491: not saving layout spanned over multiple monitors

Sun, 07 Mar 2010 23:15:36 +0100

When using Kdenlive over multiple monitors, NOT using twinview, the layout does not get saved at exit of the application. When using twinview, the layout does get saved. So, only layout on not more then 2 monitors can be saved.

0001488: Render button should not be a drop down menu

Sun, 07 Mar 2010 22:25:00 +0100

At the moment the render button is actually a clickable dropdown list, which is unorthodox and fairly confusing from a user stand point. It simply isn't obvious that it is clickable. It also makes it easy to click the button instead of the arrow on left.

There are also only two options : Render and Generate Script. It is therefore easy to simply have two separate buttons side by side.

I have provided a patch that makes that little change (two buttons instead of dropdown list). It is not much, but this has been bugging me for a while ;)

Feel free to test it and commit it to svn.

0001487: crash on deleting a clip

Sun, 07 Mar 2010 22:15:15 +0100

0001486: Export silently fails to render video.

Sun, 07 Mar 2010 15:59:29 +0100

I'm using kdenlive from the official Debian testing repository. Also ffmpeg is form this repository and it has only a few codecs enabled (I assume this is a Debian policy).
I'd like to see only rendering profiles whitch I can actually use, but this is a wish.
The bug is the incorrect behavior, because the export process completes without any error message. I expect everything to be ok, but when I play the resulting video only the audio channel is saved.
I expect to get some kind of warning like "Codec not available" before the rendering starts.

0001484: Effect stacking broken

Sun, 07 Mar 2010 08:08:49 +0100

First clip has a transition (dissolve with track auto)
Second clip has a transition (composite with track black)

The composition scales a clip (png) to 130% positions to bottom and then pans the clip until its top (vertical pan).

First clip position is displaced as soon as the time line reaches the start of the second clip with the composite transition.

0001483: crashing when using some of the lumaxx.pgm.png wipe

When using some of the lumaxx.pgm.png wipe transition Kdenlive will crash.

0001482: using "insert space" after "split audio" results in a segmentation fault

Sat, 06 Mar 2010 20:04:22 +0100

If you use "split audio" on a clip and then attempt to use "insert space" on an empty audio tracks, the kdenlive crashes with a segmentation fault.

0001481: after "split audio" it's not possible to cut the clip

Sat, 06 Mar 2010 19:54:33 +0100

By using "split audio" on a clip, the audio is moved to a separate audio track, but then it's not possible to cut the clip (or join the audio and video track). The only way out of this is using "undo".

Obviously the video and audio tracks are somehow related - I'd expect that "split audio" results in a completely separate audio track, so that it's possible to cut the audio and video tracks separately.

Or maybe the tracks could be cut simultaneously (cutting one of them cuts also the other one at the same place), but now it's not possible to cut them at all.
