Hello to all.
As an experienced beginner, I tried this first script indicated on the gmic site here:
https://gmic.eu/tutorial/cauldron_anyone.html

What was my great disappointment to see a first error message. For a tutorial, it's not good.

First, if the -display line is added as indicated in the tutorial, the script will stop when the image is displayed.

Nothing serious, I remove this command.

But the output does not want to go out, a dimension error.

It would be nice if the tutorials were not traps that lead to frustration.

Would you have a solution so that the animation render is the one of the tutorial and not an ugly error line in the terminal?

I think I understand

the output must specify the name of the container.
video.mp4,24
animation.mp4,24

But not the desired file name as I wrote it

cauldron.mp,24
because no video container is called cauldron

Does it's correct?

If it's about G'MIC (and coding?), I think you better off by asking directly the G'MIC team over there > https://discuss.pixls.us/tag/gmic IMVHO. (yes they are all other there and very nice people as well ).
OK, it's one more registration/sign in, but it's really worth it

I'm really sorry, I made a mistake in the 'community' menu of the gmic site.
Pease leave the topic open until tomorrow, it's late tonight, and I'm more likely to go to bed than to register on a new forum.
Thanks for your answer and sorry for my mistake.
