This video is quite unusual, as it moves from right to left throughout the song.
How would we automate this with Shotcut? I rarely use keyframes, but once the entire video is edited, it just goes into a carousel…
Just copy paste the filter of the first and second clip to the third and fourth clip. And the do the same for later ones too. You have the right to left thing, you don’t need to keyframe it each time, just 4 keyframes are enough to recreate it (assuming you would copy them on other clips., also you can do it with two tracks only, just place every odd clip on the first track and even clip on the second track.
This is pretty simple, I don’t have the way to automate the copy pasting process.
The explanation is very abstract for me right now. The small detail I notice is that all the clips have a black border on the right!
Just for my needs so far, I’ve zoomed in a bit, but never a carousel.

Hi @MonSr , I did it, but I wouldn’t say it was easy… 
You can easily replace the pink borders with black.
Here’s my Shotcut timeline:
If I get a spare few minutes, I can replace the photos with colour clips and post the MLT for you to examine, to show how I keyframed it - if that would be useful to you.

@MonSr - Here you go, photos replaced with colour clips. Also black borders!:

I started working on this too yesterday but didn’t have time to finish.
A bit different from your method @jonray. I slightly cropped each clip to create the spacing between each one.
Of course for the copying/pasting of the filters to work correctly, all clips should have the same length. Also, when you’re done animating all the clips, the filters will need to be edited on the first clip if you don’t want it to start OUTSIDE the screen and to be cropped.

Oh, that is quite clever!! Great tutorial, too - thanks! (BTW… If you wanted a different colour border, other than black, then you could move all the clips up one track and place a long colour clip on V1). Great stuff…

Thanks for pointing this out.
There is already a black clip in track V1. So yes, to change the color (or colour ) of the space between the clips, just change the color of that V1 clip.

Oh yes, didn’t spot that. Quick tip BTW for new users who may be reading this: no need to open a new colour clip to change colour - select the black clip and change its colour in “properties”.

I also tried another way … I found it useful to quickly make a transparent PNG with a white border on the right (note the black colour will be transparent when imported into Shotcut.
It just helped me with the keyframing. I can then change the border to black by adding an “Invert Colour” filter… or another colour by adding a “Colour Grading” filter. Just another slight variation. More than one way to skin a cat…

Vous avez raison, mais il n’y a pas que cela. C’est beaucoup plus facile si vos images sont au format de votre projet. Essayez de faire la même animation avec 5 images qui ne sont pas au format/ratio du projet. Et pour compliquer un peu, elles ne doivent pas avoir toutes les 5 le même ratio. Le premier filtre à appliquer est le “Crop source”, mais c’est ensuite que cela se complique. Sortez les calculettes, moi je n’ai encore pas trouvé de solution simple.

You’re right, but there’s more to it than that. It’s much easier if your images are in your project format. Try making the same animation with five images that aren’t in the project format/ratio. And to complicate things a bit, they shouldn’t all have the same aspect ratio. The first filter to apply is the “Crop Source,” but that’s where it gets complicated. Get out your calculators; I haven’t found a simple solution yet.

@Namna vous avez raison.
Comme dans toutes choses, quand on veux se simplifier la vie, la préparation est la clé.
Dans le cas d’un project comme celui-ci (répliquer le déffilement horizontal du vidéo-clip original) la première étape serait de préparer à l’avance tous les clips pour s’assurer qu’ils ont la même durée et les mêmes dimensions.
As in all things, when you want to simplify your life, preparation is key.
In the case of a project like this one (replicating the horizontal scrolling seen in the original video clip) the first step would be to prepare all the clips in advance to ensure that they have the same length and dimensions.

Yes, mine were all 1920 x 1080. Without that, it would indeed be tricky.
Oui, les miennes étaient toutes en 1920 x 1080. Sans cela, ce serait effectivement délicat.

@jonray Thanks for taking the time to demonstrate… I had already thought about that and said to myself, first I have to define the route to follow, then learn the technique, and finally decide what’s most appropriate.
Gregory’s song has at least 48 video clips, which is harder to manage than 48 photos. The border can be applied to all the photos in bulk, using XnView.
I’ll sit down one day, as soon as I can prioritize this, and then I’ll post what I was able to do, but I can’t promise 
anything. Since these issues get closed in three months, we’re screwed/JODIDOS 
Yeah, I’d thought about that, but only with videos… what I can assure you is that I don’t plan on working with a ton of tracks. Reductionism tells me:
FIRST. Add a border one by one to all the clips in the same track.
SECOND. Export the video.
THIRD. Import the video and move it from right to left.
