Create overlay animated gif from youtube video stills on Windows 10 with freeware
I have a one-time need to create an animated GIF overlay on Windows from a
YouTube animation. I just did it the first way I thought of doing it.
I just ask your advice on how to improve the process using basic freeware
1 Here is the original youtube video animation.
2 Here are a few hundred same-sized JPEG screenshots every 1/10th of a
second using Irfanview freeware automation on Windows.
3 Here is the new layer that will be overlayed onto each of those JPG
screenshots drawn with Paint.net freeware.
4 Here is that same overlay file with the underlying layer removed so the
only layer left is the red lined boundary PDN file I want superimposed on
every screenshot (this file is a GIF only because the PDN would not
5 In Irfanview batch mode, I use "Add watermark image" to batch overlay
the single-layer boundary.pdn on top of every screenshot JPG file.
6 Assemble the JPGs into an animated GIF using ffmpeg from Imagemagick
freeware on Windows.
The convert command on Windows doesn't seem to be from Imagemagick.
c:\ convert -delay 15 -loop 0 *.jpg animation.gif
So I'm stuck using ffmpeg which is from Imagemagick.
c:\ ffmpeg -f image2 -framerate 9 -i *.jpg out.gif
The last step is the part that isn't working since the files aren't being
found and all the help uses confusing %% syntax.
