*******************
26Mar2015 Remake all 3 segments (including "") 10 seconds long each, which don't really match the voice, but will make the animation more "comfortable".


First build of animation with full 3*10-second sequences

A. Copy all images from the 3 "sub-animations" directories into the "Combined xcf files" directory.  These should ALL be in correct numerical sequence (same base filename).

B. Produce jpg files from xcf files 
1. gimp-Open first xcf image in "Combined xcf files" directory 
2. gimp menu -> video -> frames convert :
   from .xcf format in directory :  
      /home/bill/Projects/Stalin supported Hitler/animations - Howell/Opening_Context/01.5 A_year_of_stunning_victories/10 Combined xcf/
   to jpg format in directory :  
      /home/bill/Projects/Stalin supported Hitler/animations - Howell/Opening_Context/01.5 A_year_of_stunning_victories/15 Combined jpg/
3. close gimp to avoid confusion!

C. Produce ogv video
1. open OpenShot
2. menu File -> Import image sequence : 
   Filename pattern :  Dunkirk halt-%06d.jpg
      Note : "%06d" denotes a 0-padded number sequence
   Frames per image : 1
   Repeat sequence : leave blank for this project
   Image folder : 
      /home/bill/Projects/Stalin supported Hitler/animations - Howell/Opening_Context/01.5 A_year_of_stunning_victories/15 Combined jpg/
3. Back in openshot main window 
   drag "Dunkirk halt-%06d.jpg" icon to "track 1"
   menu File -> export video
   File name :  01.5 A_year_of_stunning_victories
   Export to folder : 
      /home/bill/Projects/Stalin supported Hitler/animations - Howell/Opening_Context/01.5 A_year_of_stunning_victories/
   Profile : All formats
   Target  : OGG (theora/vorbis)
   Video profile : 768x576 4:3 PAL (closest to 770x570)
   Quality :  Med (for now...)
   Click button "Export video"
.
>> Result of first build >  Good, except a weird "reqwind" to the beginning at the end of the animation.



*******************
25Mar2015 Combine initial 2 of 3 animation sequences :
1. Copy sequence of images 
   from : 
      /home/bill/Projects/Stalin supported Hitler/animations - Howell/Opening_Context/01.5 A_year_of_stunning_victories/1 Europe scale/
   and : 
      /home/bill/Projects/Stalin supported Hitler/animations - Howell/Opening_Context/01.5 A_year_of_stunning_victories/2 Nazi invade lowlands & France/
   to :  
      /home/bill/Projects/Stalin supported Hitler/animations - Howell/Opening_Context/01.5 A_year_of_stunning_victories/10 Combined animation/

   plus duplicate "Dunkirk halt-0048.xcf" as "Dunkirk halt-0049.xcf"
   to "fill a gap" in sequence
.
2. gimp -> video -> frames convert :
   from .xcf format in directory :  
      /home/bill/Projects/Stalin supported Hitler/animations - Howell/Opening_Context/01.5 A_year_of_stunning_victories/10 Combined animation/
   to jpg format in directory :  
      /home/bill/Projects/Stalin supported Hitler/animations - Howell/Opening_Context/01.5 A_year_of_stunning_victories/15 Combined jpg/
.
3. Now, how to convert a jpg image sequence to an ogv video format?

http://www.pc-freak.net/blog/converting-jpeg-images-mp4-video-linux/
avconv -i SDC106001.JPG SDC10595.JPG SDC13611.JPG SDC13612.JPG SDC13614.JPG  movie-from-pictures.mp4
.
$ avconv --help
bash script) to run : /home/bill/bin/jpg_to_ogv.sh

Couldn't get avconv or ffmpeg to work!!!
I donloaded "OpenShot" video editor, and it is cludgy but works OK - put into ogv format.


4. In running the video, 
    2s is way too fast for  "1 Europe scale"
    4s is a bit fast for "2 Nazi invade lowlands & France"
 
So I'll make all 3 segments (including "") 10 seconds long each, which don't really match the voice, but will make thge animation more "comfortable".
