A delay between the frames can be generated as follows:

ffmpeg -r 0.25 -pattern_type glob -i 'test*.jpg' -r 25 -c:v libx264  out.mp4

I'm afraid that GIF files are not an option, with their 256-entry colour table.

Also, what I would like to achieve would be:
- pause on one image
- gradual transition to next
- pause on next image
(etc)

What I would do, is generating "paused" and fading frames at will using imagemagick:


Then animate the result with ffmpeg. I guess you will only need a small framerate (12 at most).
Others will certainly suggest something smarter

I'm sorry I don't have any useful suggestions. My work requires that I used high-end video editing software, so I've never delved into other ways of doing it.

It did occur to me that maybe PowerPoint could do what you want, but I've never used it and I don't know if it compromises the colors.

Rene, sorry if I did not express myself clearly. What I meant is that B. 408 was not produced the way a printer produces a book arranging his pages in a certain order on a big paper sheet, which is printed, folded and cut or even like a medieval scribe (how you arrange the psalms when producing a psalter is a good example), but that single bifolioos were written, most likely in the order f. 1 r + v and 2  r + v and at some time ordered according to topics and bound together. This does not matter much in the herbal part, but gives a  not coherent text in something like q. 13 or 20. That is why I think to present the ms. like an orderly produced book is misleading. This could have consequences,  e.g. for the meaning of glyphs as well, but that is another matter

Hi Marco,

it would be good if after each fade a number (let's say 25) of the 6 original images are inserted. You could simulate breaks this way.
Duplicating is easy, of course, but how do one correctly number all together ?


Edit: I copied it manually, the result looks like this:

Marco, many thanks!
That is quite close to what I hoped to achieve.

Privately, I don't have Linux, and in general I don't seem to have access to ffmpeg.

Do you have access to a Mac, Rene? It's Unix.

Thanks also to bi3mw!!

The JPEG's I generated are quite large.  They were sampled from the original digital scan with half the width and height, which is still a bit much for these types of animation. (THe height of around 1800 pixels does not fit on normal screens).
I wonder how large the video files of Marco and bi3mw are...

Hi Rene,

scaling to half the size is 905.9 kB.
