Add Background Pictures and AVI’s to MikuMikudance MMD

How to add background pictures and AVI video backgrounds to MikuMikuDance

          One of the most under-utilized features of MikuMikuDance is adding background video and pictures to the animation (Although, I’m starting to see more movies featuring up loaders dancing alongside of a model). Imagine adding Miku or any other Vocaloid to your family or vacation pictures and videos. This is something a brand new MMDer can do almost immediately after getting MikuMikuDance!

Adding Background Pictures to MMD

BackgrounAdd background pictures and AVI through the Background Tab in MMD 7.39.d tab In MMD

MikuMikuDance will open just about any common image format except GIFs (If you try to load a GIF file, you’ll get a “cannot open BMP file” error message). First, select the picture you want to use. Copy/Paste it into your Background folder in MikuMikuDance. Go to your main menu. Click on the Background tab and select load background picture file and load your photo.

If you don’t like the orientation of your photo you will have to edit the size and otherwise manipulate the image. You can use Microsoft Paint, Adobe Photoshop, or Gimp. With enough trial and error, you’ll get it to exactly how you want your background photo situated.

Add background pictures in MikuMikuDance Some advice you should first find out your screen size (it’s one of the choices under the view tab of your main menu) and use that as a starting point for your edits.  Background photos and videos are loaded dead center and MMD will not allow you to move them.

Loading AVI’s to your Background.

The steps for loading a background AVI (Audio Visual Interleave) are exactly the same as loading a background picture.  The only difference is you choose the load background AVI file. Please note, no footage will actually show, or play, until you load a model and motion data and click play. You will not hear any audio from your AVI footage either. Please also note that AVI 1 is the only video format that MMD will play in the background.

I’ll be the first to admit that this feature stumped me for the longest time. I kept getting a “Cannot open AVI” error message. This message tormented me until I downloaded and installed the Windows 7 Codec Pack from cnet.com and ffdshow from Sourceforge.net. The links for these two downloads are at the bottom of the article.Haku and the Fireworks! Add background pictures and video backgrounds for instant results in MMD I would also mention that you would choose the Codec Pack appropriate for your operating system.

Whenever you load a background picture or AVI, it will always stay in the background. No matter how you change the model view or manipulate the view angle it will be locked into the background. If your animation is longer than your background footage then it will just freeze on its last frame until MikuMikuDance finishes with the motion data.



Have fun with this.

Post Note:

You can use background video footage as a reference for your own animations. (See this article: https://learnmmd.com/http:/learnmmd.com/use-the-background-avi-to-make-realistic-animations-in-mmd-7-39/ ) You can also zoom in and out and reposition the background pictures by holding your keyboard’s control (ctrl) key and clicking on the zoom and position icons at the top right of the main display panel.

I found some great fractal footage at Nosro1’s YouTube account and thought it would make some great background footage. So I made a video for our YouTube Account.  Here’s the link: http://youtu.be/5NteV3ni2ZQ .

Here is the link to the original Fractal footage:


You should just check out the other uploads in that account. Beautiful stuff.

    Hi! Which pack from the Windows 7 Codec Pack do I download?

    I honestly have no idea where to ask this, so I’m going to try here (´・ω・`). So whenever I load an AVI file (Of the correct codec), it creates a right and left transposed split screen. I haven’t seen this problem anywhere else. and it happens with every AVI file I’ve used. It works perfectly fine when I play back the video, but the second I load it into MMD, it gets messed up.

    • July 13, 2017    

      You mean, you load it as a background, right? Does it happen when you load it into absolutely empty MMD screen just launched, no effects or anything? There might be some glitch in your codec’s settings. When you’re playing the video, in or outside MMD, do additional icons appear in the right corner of your taskbar? If so, you could summon codec’s properties window and see if there’s something that could cause the effect you describe.

        Yes, I do load it as a background with no effects, models, etc. and no icons seem to appear. I have checked the properties of the video and compared it with the information of others, and it all matches perfectly. If it means anything, I edit my videos in Corel VideoStudio Pro X6, and convert the file through that, and I got the video off of YouTube through keepvid.com. Thanks for responding so quickly before.

        • July 14, 2017    

          I meant properties of the codec, not of the video. For example, for ffdshow (one of the more popular ones) it looks like this:
          Unfortunately, without knowing what codecs do you have installed in your system it’s hard to tell how to reach their settings and what to look for in them. I hoped that a taskbar icon would give a hint, but apparently no. You’d have to ask somebody who has a first-hand access to your computer.

            I’ve installed ffdshow and have had absolute confusion and no luck. A few of use worked on this for a couple hours, but all we could find is that this is a Microsoft Video 1 problem and can’t seem to be fixed due to old age of the codec. I thank you for your help, but I think this one may be uncorrectable. Is there perhaps another MMD-compatible codec that I have somehow missed?

            • Sal Sal

              Compression, not codec. Sorry.

  3. July 10, 2017    

    I downloaded both those things but nothing really changed. Are they video converters? Do they just add the option to converters i already have? I don’t understand what the point of those 2 downloads are. I still can’t play videos.

    • July 11, 2017    

      Did you just “download” them or install them as well on your computer? These two things are codec packs (well, ffdshow is an individual codec, but oh well) used to play and encode videos. MMD is known to be rather picky about which codecs it will or will not work with, but these usually solve the problem.
