GIF effects

[meetdilip]

Hi, can we add effects between images while creating a GIF ? Something like Fade ? I wonder whether there is any GIF effects plugin available. Thanks.

I have a progressive-merge-0.1.py script (no documentation) at the usual place, that will generate the fade animation between two layers.

But don't mistake Gimp for a video editor. At some point you are better off using video tools to generate a video, and then make a GIF out of that video.

Similar general comment as Ofnuts, a video editor such as OpenShot will string together png images, and add any number of transitions available.

However for Gimp. An old plugin MathMap. Lots of filters available, a few of them transitions between two layers. (edit: look in the Extra-Animation section )

As you might expect, this works in RGB mode and you might have a little hand editing - remove the starting frame - reverse stack order - before assembling into a gif animation.

The link to the plugin and explanations here: https://www.gimp-forum.net/Thread-MathMap-for-Linux It does work with an appimage, if that is what you are using. It does take a bit of practice.

Thanks @ofnuts @rich2005 . Yes, I am using an app image suggest by this forum. It is 2.10.25 with plugins on 20.04.

I will try the script @ofnuts , :thankful

@rich2005 I will check MathMap, too sleepy now. Please allow me a few hours

I installed GAP through the Synaptic Package manager. But there is no option for transitions. I use Kdenlive. Perhaps it is time to check whether it offers basic text animations like Fly in, fade etc. I tried to install OpenShot from the Ubuntu store, but something went wrong.

Do you think GAP is suitable for simple animations for a GIF ? I installed 2.56 or something but this link says GAP 4 is available

Thanks for your time

Packing in for the night.

The old GAP packages are very flaky. Version 4 is a possibility but you will need to compile it. I always think GAP is a bit over complicated, especially for a transition.

edit: A look at 'version' 4  Not Gimp-GAP but GAP a mathematical application.

There is a Openshot appimage, which works ok except the webp format fails. Webp would be a great shortcut to get a transition into Gimp.  Must investigate further.

This the mathmap animated droste filter - with background removed - new background substituted

I will check OpenShot. MathMap filter looks promising. Let us see which one is easier.
