Saving a stack as a Quicktime Movie

[Philip Ershler]

Hello,
        I have modified the Batch Image processing plugin so that I can batch Quicktime movies as

1. Open the Quicktime Movie
2. Set an ROI
3. Crop the stack to the ROI
4. Save the stack back out as a compressed Quicktime movie (hopefully)

        Here is a snipette of code that "almost" works.

        public void convert(String dir1, String dir2, String format) {
                IJ.log("\\Clear");
                IJ.log("dir1: "+dir1);
                IJ.log("dir2: "+dir2);
                String[] list = new File(dir1).list();
                if (list==null) return;
                for (int i=0; i<list.length; i++) {
                        IJ.showProgress(i, list.length);
                        IJ.showStatus(i+"/"+list.length);
                        boolean isDir = (new File(dir1+list[i])).isDirectory();
                        if (!isDir && !list[i].startsWith(".")) {
                                theOpener = new My_QT_Movie_Opener(); // QT_Movie_Opener modified so it does not display a dialog "Convert to 8 bit"
                                theOpener.run(dir1+list[i]);
                                theIp = IJ.getImage();
                                theIp.setRoi(197, 74, 405, 354);
                                IJ.run(theIp, "Crop", "");
                                theIp.setTitle("temp.mov");
                                //IJ.log(" \"QuickTime Movie...\", \"compression=Sorenson quality=Normal frame=30 save=" + dir2 + list[i] + "\" ");
                                IJ.run(" \"QuickTime Movie...\", \"compression=Sorenson quality=Normal frame=30 save=" + dir2 + list[i] + "\" ");
                                IJ.run("Close");
                        }
                }
                IJ.showProgress(1.0);
                IJ.showStatus("Done converting " + list.length + " files");
        }

        Everything down to this line, which is what comes from recording a plugin for one pass through the 4 steps above, which works properly.

IJ.run(" \"QuickTime Movie...\", \"compression=Sorenson quality=Normal frame=30 save=" + dir2 + list[i] + "\" ");

        When it hits this line the machine complains "unknown command". At this point I have a cropped stack ready to be written out. What is the correct way to write a stack out as a Quicktime movie from a plugin?

Thanks, Phil

Hi Phil,

IJ.run(" \"QuickTime Movie...\", \"compression=Sorenson quality=Normal
> frame=30 save=" + dir2 + list[i] + "\" ");
>

Your command is enclosed in an extraneous outer set of quotes. Try this
instead:

IJ.run("QuickTime Movie...", "compression=Sorenson quality=Normal frame=30
save=" + dir2 + list[i]);

Regards,
Curtis
