问题
I would like to use the AVI_Writer from the ImageJ API in my java program. However, even though I can automate the movie writing, I haven't found out how to change the framerate when using the method:
writeImage(ImagePlus imp, java.lang.String path, int compression, int jpegQuality)
Any idea?
Thanks.

If you look at the menu command for saving as AVI, it has an option to set the frame rate, which is taken from a setting hidden in Image > Stacks > Tools > Animation Options... in the menu.
Using the command finder, which you can invoke by typing [L], you find the sources for these two commands:
- File > Save As > AVI... =>
ij.plugin.filter.AVI_Writer
- Image > Stacks > Tools > Animation Options... =>
ij.plugin.Animator("options")
The command finder provides a handy button that directly links to the source files, have a look here and here. You'll find that the frame rate setting is stored as fps
in the Calibration of the ImagePlus.
