Convert 3D movies with split frames to Anaglyph 3D movies for viewing with red (blue/cyan/green) 3D glasses.

Convert from Video File with Frame Position

If a 3D video is available, frames can be extracted by specifying the frame position. 3D video files can be found here.

BufferedImage frame = FleurVideo.extract(new File("3dVideo.mp4"), 6000);

List<BufferedImage> splited = Fleur3dUtil.split(frame);
BufferedImage frameCombined = FleurFilter.additive(
        FleurFilter.color(splited.get(0), ColorMask.RED),
        FleurFilter.color(splited.get(1), ColorMask.CYAN));

ImageHelper.saveImage(frameCombined, "frame_combined.png");

Steps to Convert

1. Extract Frames from Video File

FleurVideo.extract(new File("3dVideo.mp4"), 6000);

2. Split and Stretch Frames

Left Frame	Right Frame

List<BufferedImage> splited = Fleur3dUtil.split(frame);

3. Combine Frames without Color Filtering

BufferedImage combined = FleurFilter.alphaCombine(frame1, frame2);

4. Apply Color Filters

Left Frame with Red Filter	Right Frame with Cyan Filter

BufferedImage redFilterImg = FleurFilter.color(splited.get(0), FilterColor.RED);
BufferedImage greenBlueFilterImg = FleurFilter.color(splited.get(1), FilterColor.CYAN);

5. Combine Frames with Additive Filtering

BufferedImage additiveCombinedFrame = FleurFilter.additive(
        FleurFilter.color(splited.get(0), FilterColor.RED),
        FleurFilter.color(splited.get(1), FilterColor.CYAN)
);

6. Compile to Video

List<BufferedImage> images = FleurVideo.extract(new File("3dVideo.mp4"), 6000, 6010);
List<BufferedImage> videoImages = new ArrayList<>();

for (BufferedImage image : images) {
    List<BufferedImage> splits = Fleur3dUtil.split(image);

    videoImages.add(FleurFilter.additive(
            FleurFilter.color(splits.get(0), ColorMask.RED),
            FleurFilter.color(splits.get(1), ColorMask.CYAN)
    ));
}

FleurVideo.create(videoImages, "3dVideoOut.mp4");

7. Compile to Polarized 3D Video (Left/Right)

Left Video	Right Video

List<BufferedImage> images = FleurVideo.extract(new File("3dVideo.mp4"), 6000, 6100);
List<BufferedImage> leftArray = new ArrayList<>();
List<BufferedImage> rightArray = new ArrayList<>();

for (BufferedImage image : images) {
    List<BufferedImage> splits = Fleur3dUtil.split(image);
    leftArray.add(splits.get(0));
    rightArray.add(splits.get(1));
}

FleurVideo.create(leftArray, "left.mp4");
FleurVideo.create(rightArray, "right.mp4");

To view: play both videos on separate projectors or use active shutter 3D glasses on a 60Hz monitor.
