  I finally found some time to do something I've been thinking of for a long time.
  
  It is still work in progress, but the first results, while not yet satisfactory to me, are at least encouraging.
  The following is the result of mostly, but not entirely, automatic processing. The manual part can still be reduced a lot, which I will need to do if I want to apply this to a larger number of pages.
  
  So here goes.
  
  Imagine one has a sheet of blank vellum:
  
  You are not allowed to view links. Register or Login to view.
  
  Then imagine one draws a plant on it....
  
  You are not allowed to view links. Register or Login to view.
  
  and then adds some text
  
  You are not allowed to view links. Register or Login to view.
  
  and paints it with lots of green and some other colours
  
  You are not allowed to view links. Register or Login to view.
  
  the same is done to the other side
  
  You are not allowed to view links. Register or Login to view.
  
  and finally it is bound in a book.
  
  You are not allowed to view links. Register or Login to view.
  
  I'm still working on important improvements, but I also have a question.
  Who has some good advice for combining JPEG's into a movie (mpeg , mp4, what have you)?
  
  Many thanks in advance!

  Hi Rene, step 2 looks particularly interesting  
  It's something I tried doing in the past, but with quite poor results.
  
  For generating animations, I use this on the Ubuntu command-line:
  
  

  Code:

  ffmpeg -framerate 24  -pattern_type glob -i '*.jpg'  -c:v libx264  out.mp4

  I agree, the difference between the line-art and the colored version would be quite useful in some cases. Although I fear that for many plants entire parts would be lost due to the thick paint?

  As far as I remember correctly was the conversion of image sequences possible with You are not allowed to view links. Register or Login to view. . Output is Mp4 / AVi.
  
  For Linux you can use ffmpeg on the commandline ( You are not allowed to view links. Register or Login to view. ).

  I have tried my hand on an electronic reconstruction of B. 408, it did not get far because I only used it to check some of my hypotheses and it was not meant for publicaiton, but what I want to say is that what you do is a bit misleading, I mean you have realized that there are bifolios and quires and that this fact is of some importance as well as the original state of B. 408?

  Animated gif makers can combine your images, or movie maker software can use images as well, just a matter of setting the timing to display the images.

  To make the movie file I used ffmpeg:
  
  

  Code:

  ffmpeg -framerate 4  -pattern_type glob -i 'test*.jpg'  -c:v libx264  out.mp4

  
  Then to make the gif:
  
  

  Code:

  ffmpeg -i out.mp4 out.gif

  
  And I made it a bit smaller using "convert" from ImageMagick:
  
  

  Code:

  convert out.gif -resize 700 out2.gif

  Helmut, I am trying to understand what you mean.
  
  Of course, I am aware that the MS was prepared as a set of bifolios that were later bound together. I think we may safely assume that the person doing this was completely aware how the nested bifolios would end up in the book. This was nothing mysterious - completely standard practice.
  
  It is possible, of course, that the nesting of bifolios into quires that we now have is not how it was originally intended, but we cannot be certain. From all I have seen and heard, I would say that:
  - it is indeed quite possible that the bifolios have been shuffled
  - if this happened, it must have happened at a quite early stage in the life of the MS.
  
  What I wrote in my opening post of this thread should not be interpreted as how I consider that the MS was bound.
  But I may have misunderstood your comment.

  Many thanks for the various suggestions about animation, and the pro-actively proposed solutions (!) in particular from doranchak.
  
  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)
