I make a robot that has an auto delay of 50 then do this.
for(int a=0;a<1000;a++;) { Rectangle screenRect= new Rectangle(300,400); al.add(r.createScreenCapture(screenRect)); } File outputfile = new File(output,"Test.mp4"); AWTSequenceEncoder enc = AWTSequenceEncoder.createSequenceEncoder(outputfile,20); for (BufferedImage bi : al) enc.encodeImage(bi); enc.finish();` output is the path to my desktop. These are the errors I have gotten:
