More specific instructions on how I constructed a Theora movie file from static frame images:
To convert from different (image, etc) formats to (lossless) .avi, use IMGCON, a utility at:
http://www.fmrib.ox.ac.uk/~yongyue/imgcon.html
http://www.fmrib.ox.ac.uk/~yongyue/imgcondl.html
TO RUN:
imgcon.exe -avi -output room.avi -list list.txt
where list.txt has the sequence of image files to include, with one file per line.
TO MAKE A DROD ROOM-SIZED VIDEO:
* Theora videos must be a multiple of 16 pixels, but DROD rooms don't fit that.
1. So, we need to start with images that have a buffer area on the right side.
Irfanview batch convert can be used for that to preprocess all the static image
frames being compiled to make a movie (the Advanced options has a special
setting in the corner for adding a pixel border around the image.)
2. Create the video, squashing the images+border to the original room size:
imgcon.exe -avi -output room.avi -scale 836 704 -list list.txt
3. Then run:
ffmpeg2theora-0.17.exe --optimize --nosound -v 10 room.avi
(Later versions, like the current 0.19, of ffmpeg2theora should also work)
When this video is played, it will be stretched to 848x704.
The video will show at the correct (room) size, albeit first unstretched and
then stretched. The buffer will be off the edge in the hidden area.
