How to get the Ken Burns effect on your digital photo frame?

The Ken Burns effect is a type of panning and zooming effect which makes still imagery come to life.

In this short article, I will show you, how you can get this effect for your digital picture frame.

As always, I will be using the image viewer Pi3D.

What is the Ken Burns effect?

The name derives from American documentarian Ken Burns who was known to use this technique extensively.

Legend has it, that Steve Jobs approached Burns to let him use this effect on Apple computers and since then the effect effect is ubiquitous screensavers and slideshows.

Burns embedded still photos in motion pictures, shown with slow zooming and panning effects, and fading transitions between frames. The technique is mainly used when no moving images are available like with e.g. historical photographies predating the age of the film.

As you can’t really explain the effect with a photo, here is a video:

It looks very smooth and combined with the deep voice of the narrator pulls you into the photo, sometimes with surprises when you start from just one small area of the image and only gradually reveal the full story by zooming out or moving to another area on the photo.

So why not use it on a digital picture frame?

Configuring Pi3D to use the Ken Burns effect

As luck would have it, Paddy has included the Ken Burns effect in to the Pi3D image viewer.

If this is the first time that you hear of Pi3D, have a look at this article first.

I assume that you have installed Pi3D by now. In fact all you to do is open the PictureFrame2020config.py file and find this line:

parse.add_argument("-u", "--kenburns",      default=False, type=str_to_bool, help="will set FIT->False and BLUR_EDGES->False")

Set “default=True”, save the file and close it. You’re done.

Start the PictureFrame2020 script.

The movement of the photos is very smooth. The speed depends on a few factors, most notably the aspect ratio of the image. The more the images correspond to the dimensions of the screen, the smoother the effect will be.

Conclusion

Ken Burns is a very nice feature of Pi3D that can bring some life to your images. Given the very smooth and gradual movement of the image, it doesn’t create a disturbance but blends in nicely.

Are you using the Ken Burns effect? Let me know!
