Clockwise vs. Anti-Clockwise Keyframing

In Shotcut, I can easily rotate and keyframe a “Green” image (e.g., 30 degrees clockwise tilt with movement). How can I achieve the same kind of animated rotation with a “Red” image, but in an anti-clockwise direction? @MusicalBox

Hi,
I answer because MusicalBox is currently asleep. :sleeping: :zzz:
Anticlockwise = negative values.
So:
Green image clockwise : Rotate 0 to 30
Red image anticlockwise: Rotate 0 to -30

If you do it like that, the image will spin around. It won’t work

The method explained by @SergeC works.

I’ll give it a try again immediately when I get into the studio. If it works, I’m not sure what went wrong with my previous project. If you watch this video and skip to 18 seconds or wait until 18 seconds, you’ll notice the anti-clockwise picture isn’t moving smoothly like the clockwise image. That’s what brought me here in the first place.

Pas à coup sur.
Cela dépend de la taille du projet et de la taille des images.
Dans cet exemple, une image carré dans un projet 16:9 ne fonctionne pas avec un seul filtre SPR.
Il faut d’abord recadrer l’image avec un Crop rectangle.

Not necessarily.
It depends on the size of the project and the size of the images.
In this example, a square image in a 16:9 project won’t work with a single SPR filter.
You must first crop the image with a Rectangle Crop.

Still does the same Spinnin’ around

With this .zip example, I hope you’ll understand what’s going wrong with your project. It should work normally. :slightly_smiling_face:

Maybe if you share the MLT file of that video we can see what is going wrong.

@Namna you’re right, size does matter.

However I think it’s fair to mention that you’ve set Size Mode to Distort to make your color clips square. We wouldn’t do it on a 16:9 photo as it would squish the image horizontally.

We’d first need to either use a Crop filter, like you explained, or use an external image editor to crop the photo at a square shape before importing it in Shotcut…

Je suis parti sur des clips couleurs car c’est ce que l’OP a utilisé dans son premier post.
En mode “Déformé” le filtre SPR permet d’obtenir un carré à partir d’une image rectangulaire. Mais après “rotation” l’image est à nouveau déformée.
Pour utiliser des images rectangulaires et les transformer en carré, on peut utiliser comme vous le mentionnez un logiciel externe, ou tout simplement remplacer “Crop Rectangle” par “Crop Source”.

I used color clips because that’s what the OP used in their first post.
In “Distorted” mode, the SPR filter allows you to create a square from a rectangular image. But after “rotation,” the image is distorted again.
To use rectangular images and transform them into squares, you can use external software, as you mentioned, or simply replace “Crop Rectangle” with “Crop Source.”
