Hello,

First of all, I am new to kdenlive and video edition in general.

I am making a video from a set of photos. Because the video is in 16:9 format and my photos aren't, I want to put an image behind the photos to fill the size. What I'm trying to do is using two video tracks, one with the sequence of photos and the other with a still image and compositing the final video with photos in front of the back image. But I'm having problems and I can't get what I want.

Is there any help to make this? Thanks in advacne.

- Place photos on video 2
- Place background on video 3
- Insert Composite or Affine transition eiher on each photo or once on the entire track video 2 (see https://userbase.kde.org/Kdenlive/Manual/Effects)
- If more information needed: Seach forum for pip, affine or composite

I know that. My problem is that I want to make some transitions between photos, so I'm using two video tracks for photos. This way, the third track (background) is not overlaid with the other two, just with one.

Oh, I do not know, what you know, unless you tell me. Then it is misleading, when you write about two video tracks, one with photo, one with background...

To solve your problem set the "with track" option in your transition for the upmost track to the lowest track.

For example:
V1: "with track V3"
V2. "with track V3" or "auto"

Sorry for not mentioning I also want transitions between photos...

I'm trying with this:

• Video track 1: photos, with an affine transition with vt 3
• Video track 2: photos with an affine transition with vt 3
• Video track 3: still photo with the background

With this, if I arrange all photos between video tracks 1 and 2, the final video is correct, but I don't have any transition between photos.

To make transitions between photos, then I overlay the fist second of photo in track 2 with the last one of the one in track 1, but then I can't put another transition (a disolver, for example), because I'm already using one (the affine).

Then I have tried to cut the affine transition of vt 1, leaving the last second without it. So I can put a dissolve transition with vt 2. With this configuration, I have both, the background and the dissolve transition between photos, but this last transition is not done correctly. During the transition, photos are stretched during the transition and with it is finished, then recover their original size.

I have created an example project, so you could see what I'm trying to do, and the problem I have. It's at https://www.dropbox.com/s/ejg07ady0fv59pf/kdenlive_test.zip?dl=0

Hey, that is a good one. I will take a look at the project this evening, when I am back home - if nobody else helps you out before.

OK, got your example running.

This works:
1. Attach the affine transistion to the full clips in both photo tracks
2. Affine always "with track V3" (as you did)
3. On track V1 add a keyframe where V1 and V2 overlap on the left side
4. On track V2 add a keyframe where V1 and V2 stop overlapping (right side)
5. For the latter keyframe set the opacity to 0.

This way you create a dissolve between track V1 and V2 manually by fading out the upper photo.

Thank you capslock. It works perfect!!!

Found another solution 2 minutes before going up this morning...

To make your life easier (working wihtout keyframes), you ccan also create two kdenlive projects:
1. One where you arrange all pictures and use simple dissolve transition
2. One with the background in one track

You can import the first project (.kdenlive file) as a clip into th second one and combine photos and background with one large Composite or Affine transition. That should do the same trick, but easier to achieve. Just make sure that both projects have the same settings and that you disable proxies in the first project before rendering.

I'm trying to make it this second way, but I'm having the same problem than at the beginning. That is, when the photos are disolved, the photo are strechted and when the previous photos dissapears completely, then the new one is restored to its real size.

I don't know if this why you told me to disable proxies. The fact is that I can't find what you really mean by this. The only proxy option I have found is at creating the project, where I have disabled it.

If you used proxies in the imported project, the proxy files will be used for rendering the second project. That is a known issue in kdenlive. You can enable or disable proxies when creating the project or in Project->Settings for any project. If you have used no proxies, all should be fine.

I just made a test with kdenlive 15.04. It works as described above. One project with two pics. One new project with the other kdenlive file and the background. Pics keep their size and are centered and dissolving on the background using an Affine transition. But it should be working with older versions as well.
