Plugin to fade text colour on a PNG still image with transparent background

0. Check that Setting-> Format...-> Color Model is RGBA-8bit or YUVA-8bit or RGBA-FLOAT
1. Add a Video track on the top of the Timeline: it will be used only for the text.
2. Highlight the area you want the text: 8 seconds?.
3. Insert the Title plugin in this top Video track
4. Open the Title window and set:
Color: white
Outline: black
Drop shadow: 0
Outline: 0
Stroker: 0

5. Close the Title window
6. Below the Title plugin, insert the Color3way plugin
7. Open the Color3way window
8. Enable "Generate keyframes while tweaking" (in the Cin-GG_Alterantive_shortcut version its shortcut is G)
9. Move the Insertion Point of the Timeline in the head of the Title plugin, or where you want to insert the first keyframe
10. In the Color3Way window, CHECK the "Copy to all" option of the Shadow, so Midtones and Highlights change the values together.
11. Change the colour in the Shadow Wheel Colour.
12. Repeat from point #9 for the next keyframe.
13. Close the Color3Way window and Disable "Generate keyframes while tweaking"

You can see that the text will change its colour from the first keyframe to the next.

I'm using RGB 8 bit.

Is your solution better than to use the brightness/contrast plugin for that purpose?

I guess it is more powerful because the change to colour can be set individually.

Today something is broken but yesterday I already was able to make it work from black text to white text with fades and changing plugin keyframes and so on.

This is a link to a demo video about the steps I wrote to you, if you think it can be useful:

It says "this file is empty"

I am sorry, @cincity.

https://files.fm don't show the ogv video file, but you can download it.

However I converted the "Cin_20240630_Change-Title-Colour-Using-Color3Way.ogv" video to mp4 and uploaded it here: https://files.fm/u/p7wb937wcc

And, if you want the text into a rectangle, in a kind of mask, where you can see the background video in the fill of the text,... "Cin_20240630_TitleColourInverted.mp4": https://files.fm/u/aadhb7tuyj

Thank you so much!

Would you propose to use the internal titling engine or prepare slides with Gimp?

BTW you should upload it to the youtube channel.

Masking and plugin keyframes are so difficult to handle for newbies. The first clips not only shows the pre-requisite settings and the settings of the plugin - it also shows very clear how to create and use "plugin keyframes".

Depends. For my projects I create PNGs Title because I use Proxy with "Rescaled to project size (FFMPEG only)" unchecked: my Laptop is very old and slow.

Using PNGs allows me to be independent of system fonts if I have to use another computer with a different OS (and different fonts),... and for archive use I think it is better.

But, like you can see, for the tutorials I am using Title plugin. You can use a workaround for that: convert the Title to PNG; you can see that in the "Animated Split Screens" tutorial at 1m56s:

Though I'm still using still images I would prefer to use the titler. I think it could be more flexible. I haven't been able to notice any difference on performance with the rescale check.

I'm aware of the fact of the fonts. I always have a copy of all fonts in a subfolder of my cin projects. So when I move a project from desktop <--> mobile I copy those fonts into ~/.fonts
