Is it possible that the behaviour of portrait images in Slideshow Clips changed? They used to be centered (which makes sense IMO), however since I recently updated to the latest version, both portrait and landscape images are always aligned to the left and leave a black bar on the right.

Was that an intended change? Is there any way I can get the old behaviour back?

Many thanks
Michael

If I open an old project file and render the video, everything is fine, like it used to be: images are centered.
When I add the same directory as a Slideshow Clip to a new project and then diff the relevant `producer` element it does show some changes. Showing old as '<' and new as '>':

< <property name="length">00:00:30:00</property>
---
> <property name="length">900</property>

< <property name="meta.media.width">4000</property>
< <property name="meta.media.height">2992</property>
---
> <property name="meta.media.width">3024</property>
> <property name="meta.media.height">4032</property>

> <property name="kdenlive:folderid">-1</property>
> <property name="kdenlive:duration">900</property>

When I copy those values over to my new project file it does not render images centered though... I tried to spot other differences in the project, but I didn't find the element causing this.

Hello,

I guess MLT version is also different in both cases?
MLT is responsible for the actual rendering behind Kdenlive GUI, so the different behavior is to track here.
If you play the new project with the old MLT ("/path/to/old/melt project.kdenlive") and vis-versa, I guess the behaviors are reversed?

Slideshows are qimage producers, which code had only a slight change this year. Maybe Qt Image handling has changed?
Maybe compile options? What are the diff between both "melt -query" outputs?

Not sure which one was the last version that worked, would have to try out by downgrading my packages. That was only a guess.
I still think the problem is how kdenlive constructs the project file. With the latest version of kdenlive/mlt I can still render the old file and get the same (good) result, i.e. centered images.

I have just simplified my old and new project so that both only contain the one slideshow but can't spot the problem. Randomly copying over attributes from the old to the new one didn't help. This is the project that was created with the old version of kdenlive that still works fine even when rendered with a new version:
