Attached is my own bash script 'animtext' for making cinelerra image
lists. It works for jpg and png and can automatically determines which
to use. It also works out the image size for you.
The instructions are in comments at the beginning of the script. The
script relies on you having imagemagick installed.
Just cd into the directory with your image files and type 'animtext' for
the most basic mode of operation.
Last I checked this worked. Let me know if something has broken. This
is part of a larger set of scripts which are currently in too chaotic a
state to release... But I will get them there sometime - they are
really handy for general image manipulation working with animation with
cinelerra, imagemagick and a digital camera.

#/bin/sh
#Create cinelerra style text file listing image paths for each frame
#this script can be called standalone or from within the animate script
#it takes three parameters: filetype (png or jpg) (default is to try and
determine what file type is in the directory), framerate (default is 12) and
directory to index (default is the directory from which the script is called)
#you probably need to make sure you choose a legitimate cinelerra frame rate
#examples:
#animtext
#(this uses default framerate of 12, does its own checking of the filetype in
the directory, and uses the current directory)
#
#animtext jpg 23.976 animations/sources/1/
#
#animtext jpg 30 /home/gray/animations/sources/2/
