How to Convert MPO Pictures to JPS (Stereo JPEG)

August 22nd, 2009 · 23 Comments · Shooting in 3D


You probably know that the stereo JPEG images are actually plain JPG file containing the two frames next to each other (for left and for right eye) and with an extension JPS (example above). This makes it quite simple to view, edit, convert and whatever else you need to do with them or event to make JPS files with almost any image editor there is. Unfortunately the same thing cannot be said about about the fairly new MPO (multi-picture file format) that is still being used by just a few digital cameras, among which is also the Fujifilm FinePix REAL 3D W1 camera that is able to shoot Stereo 3D pictures. It seems that Fujifilm has decided instead to go for JPS to rely on MPO files for storing the two frames required for the Stereo 3D image, but this actually makes the pictures you take with the camera almost unviewable on anything else than the camera itself or the optional 3D digital frame Fujifilm is also offering. But can we as owners of Nvidia GeForce 3D Vision or any other S3D capable setup do something in order to view these S3D images taken with the camera? We already know that Nvidia is going to add support for MPO file format in their stereo picture viewer soon, but what to do until that happens… fortunately I was able to find a solution, not very easy and elegant, but hey it works. :P

I still don’t own a Fujifilm FinePix REAL 3D W1 digital camera, but earlier today I was pointed to a review of the camera at Akihabara News with some example pictures taken in MPO format. Now the review is not great and very detailed, not to mention not covering much about the 3D functionality of the camera which is a key point in this product, but anyway I’m thankful for the images I could work on. Now lets get back to the MPO file format, which seems to be some kind of container for multiple frames (not just two) that seems to be using JPEG compression for the pictures it stores. Unfortunately there is still not a lot of software or actually more like almost no such software for viewing, editing, converting etc. these MPO files the easy way. The one program that I was able to find that can at least open and do some very basic manipulations with the MPO files was STOIK Imagic 5.0, which is not free, but it still has 15-day trial that probably should be enough for now. Then you’ll also need some sort of an image editor much like Photoshop, but almost anything with a bit more advanced editing functions should do the work.

So here is the short guide you need to follow:
– Download, Install and Run STOIK Imagic 5.0
– You need to navigate to the folder where you put the MPO images
– Right click on a MPO file and choose Split MPO file to get the two frames in separate JPG files
– Start your image editor, Photoshop or other and open one of the two JPG files you got in previous step
– Use the Canvas size function of the image editor to double the width of the first picture you’ve opened
– Import the second image (frame) and put it on the right side of the first one already present in the working canvas
– Export the final image you’ve got of the two frames next to each other into a single JPEG image and then rename the file to JPS

    thanx for converting the pictures, i have been waiting to see the W1s results in 3D vision for some time now.
    what are your impressions ?
    to me the 1st 2 look ok but far from great and the 3rd didnt work at all for me :(

  • 2 Andrew // Aug 22, 2009 at 08:39

    There will be an even easier way. Our 3D Vsion photo viewer will recognize MPO files soon. Once we can play them, all you need to do is hit ALT-F1 to take a screenshot and then you have a JPS file.

  • 3 Bloody // Aug 22, 2009 at 12:04

    Craylon, the distance between the two frames of the pictures is a bit too much for my eyes too, but I just had to work with these images, because I still don’t have the camera to take some myself ;)

    Andrew, this will definitely make it much easier, but until then we’ll have to do it the harder way, still the most important thing is that there is actually a way even now.

  • 4 Richard // Sep 22, 2009 at 23:12

    3DCombine version 5.2 can open MPO files and automatically save them as images in other 3D formats.

  • 5 Bloody // Sep 22, 2009 at 23:50

    Thanks for the info Richard, I’ll have to try that program… :)

    I haven’t used some of the programs described here. I primarily use a mac. If you download stereomaker 3D from the author’Ms Japan website the free program will do most of what you need. 1) It reads MPO files as stereo pairs. It will print and export stereo pairs. It will print anaglyphs. Maintaining proper pairing of the images you shoot i.e. proper left for proper right becomes a tricky business without care. Sharpness and noise are not necessarily problems. You can bring a stereo pair into photo shop as a panoramic but instead of printing as them as a stereo pair you move L over right let photo fuse the images photo shop appears to signal avaerage the 2 images on fusion. i.e. 10 MP from 20 MP. As you might guess noise falls sharpness rises pics print very well!

    FYI, you can split AND combine JPEG images using FinePix Viewer. Use either:

    – The FinePix Viewer software supplied with the W1 camera and V1 viewer
    – ANY version of FinePix Viewer ~updated~ to the latest version (5.5) at http://www.fujifilm.com

    Simply select exactly two JPEG’s of identical pixel resolution and the option to split/combine becomes available under the “Image Utilisation” category.

    This works every time when splitting images, but I have had problems combining SOME jpeg images. Unsure how to get it working perfectly every time.

    You will need to adjust the parralax setting of your newly created .MPO file on the camera or viewer. Both devices can save the adjusted .MPO file as a new file on your card.

    You could then order 3D prints from the USA or UK service if you/you know someone who can pay and have prints delivered to you.

    Why use MPO format and split it in to stereo pair? Fuji W1 also takes L and R picture shots and there are several free programs to view these pictures as anaglyph, direct view (parallel) or direct view (cross) etc. Is there an advantage in using MPO file and then split it?

  • 9 Arun // Jul 19, 2010 at 12:21

    OK, you split the MPO file in two, placed the pictures side by side and renamed the file as JPS.

    How do you view this JPS file in 3D? Take a print out of the picture and use it with a 3D viewer with two lenses?

  • 10 Bloody // Jul 19, 2010 at 12:33

    The MPO format is a multifunction format that allows more than two views (for stereo for example) to be saved into a single file, that is the advantage. Getting lenticular 3D prints is not so easy in some countries, so you cans tick with viewing the photos on a 3D capable display…

  • 11 Daniele Colciago // Oct 15, 2010 at 14:03

    Stereo Photo Maker (last release) let you disassemble a MPO file, splitting it in left and right pictures. Then you can see them in color anaglyph, side by side, parallel or cross eyes.
    What I don’t know is how can I send MPO files to a Panasonic VT20 3D TV. Maybe 1920×1080 inerlaced? Or 3840×1080 parallel? Have I to put them on a DVD or on a SD CARD? Please, help me!!!!

  • 12 timbo // Dec 8, 2010 at 16:54

    Does anyone know how to convert 2 JPG files (left and right) back into MPO? OrJPS into MPO?
    Thank you

  • 13 Bloody // Dec 8, 2010 at 17:30

    You can do that with the free software StereoPhoto Maker – http://stereo.jpn.org/eng/stphmkr/

  • 14 timbo // Dec 8, 2010 at 17:59

    now is it by chance possible to put a self made mpo file on a Fuji Real 3D W3 camera?
    click-dragging does not work..
    thank you

  • 15 Agsu // Jan 6, 2011 at 20:57

    This is a program that lets you manipulate the files MPO



  • 16 Phil Dhingra // Mar 2, 2011 at 20:32

    I just created a website that’ll convert MPO files for you: http://3dporch.com/

    Let me know what you think!

  • 17 GIANTO // May 1, 2011 at 08:51

    The stereo image of Batman is wrong for cross-eye (as is) observation: you must exchange the two images. Otherwise the far part of the scene will be shown as the nearest!

  • 18 Murat // Aug 10, 2011 at 11:58

    Probably someone might be interested: we’ve added support for Fuji MPO format in our free photo management software – Daminion.

  • 19 tim // Aug 13, 2011 at 03:27


    Is there a software that can create a single .jpg file combining the two files from the Fuji canmera (.jpg and .mpo), that can now be viewed on standard screen with polaroid glasses or the red/blue glasses.

    So the final out come could be,…
    Take picture using the Fuji 3D W1 camera,
    Download picture on computer (jpg & mpo),
    Run application on the picture,
    Get a combined picture,
    view picture using 3D polaroid or 3D Red/ blue glasses on the standard computer VDU.

    Some direction will be good.

    Happy clicking.

    I have a Fuji 3D camera and the display for showing the 3D images is great. Now I have something else as a question.

    I have an amount of old stereo glass-slides from the periode 1920-1940. How can I bring these images together so I can view it on the display from my camera?

  • 21 Bloody // Aug 16, 2012 at 10:42

    You need to scan and edit these on a PC in order to make them digital stereoscopic 3D pairs… you can make them in MPO format with the free StereoPhoto Maker software.

    Having just bought a Fuji W3 camera for 3D, I did not find such a program as worked quite how I like. So I wrote my own. It’s totally free. I have EXE files for both Win32 and Win64 as well as source code in Perl/Tk which works on both Linux and Windows. The link is here.


    There’s also an image-file, bulk re-naming program there. I used the two in combination to generate this page of both 2D and mostly 3D photos from my honeymoon motorcycle trip of 1000 miles. That page (only for your curiosity) is here…
