Making movies with ImageJ

ImageJ can read in a number of image formats and has a graphical user interface (for those who don't like mpeg2enc). However in saving a movie it can only build .AVI files (unless you're using a plugin).

To make a movie using ImageJ

  1) save your images in a folder:

   - if your script saves file names without space-filling 0's (e.g. Image1.jpg, Image2.jpg ...., Image10.jpg, ...., Image112.jpg) you can simply rename them using the 'rename' command.
   
   - the following will convert them all to 3-digit numbers


  > rename Image Image0 Image?.jpg

  > rename Image Image0 Image??.jpg

  2) open ImageJ:

   - if you don't have it, download from http://rsb.info.nih.gov/ij/

   - the linux version is quite big (25mb) because it contains Java runtime stuff.

   - in other OS's, the binary files are typically below (<2mb) (no I'm not lobbying for Windows!)


  3) open the images in ImageJ:

   - click on File>Import>Image Sequence...

   - just click on any of the file names that appear in a list

   - in the dialogue that appears, fill in the box for "File Name Contains" if your directory contains more than just the images

   - The image size can be arbitrary but it doesn't like compressed Tiff files (requires a separate plugin to do this). 


  4) to make sure everything's ok, check the opened stack by pressing \

   - real time animation through the stack should start. you can stop this by pressing esc or \ again. you can also move backwards and forwards by , (<) and . (>) keys.


  5) save the AVI file by clicking File>Save as...>AVI

   - enjoy
