Thought I would create a thread with some of the more common problems that people experience, due to the number of new users in the last few days:

1. Why do I have no Objects or Characters when I launch Muvizu?

The programme needs to connect to the internet the first time that you launch the application in order to build a list of Objects and Characters - if your PC is not connected to the internet or Muvizu is being blocked by a firewall then it will not be able to build a list of characters.

Allowing Muvizu through your firewall:

The programmes Muvizu.exe and Launcher.exe need to be added to the list of allowed programmes. They can be found in C:\Program Files\Muvizu\Binaries or C:\Program Files (x86)\Muvizu\Binaries if you have a 64-bit operating system.

While allowing Muvizu through your firewall has fixed this issue for most people some users have been unable to get Muvizu to connect to the internet at all, meaning Muvizu cannot build the list of characters. We are investigating this issue but you should be able to manually create the required files by downloading these fixes:

Windows 7 and Vista: Cache - Vista and 7.exe

Windows XP Cache - XP.exe

You are still able to use the vast majority of features when running Muvizu offline - although you will have to upload any videos you make through the web site as you will not be able to upload them through the application.

2. Errors beginning with "Vertex element type 5 not supported", "This game requires at least Shader Model 2.0" or "Device does not support 1x 32 FP render target format."

Unfortunately this means that your graphics card doesn't meet the minimum specifications for running Muvizu - it is based on the Unreal 3 engine which is pretty resource intensive. I have posted a guide on how you MAY be able to get Muvizu working with one of these graphics cards at but it is not guaranteed to work, and obviously you use any 3rd party software at your own risk.

3. Muvizu runs very slowly or gets an out-of memory error (general performance issues)

Muvizu is a very resource-intensive application so if you are running a lot of background programmes at the same time you may suffer a drop in performance, so I would recommend closing all unnecessary programmes while running Muvizu - especially on older PCs.

If you have Windows 7 or Vista closing Aero and the Side Bar can also increase performance:

Close Side Bar:
The following tutorial is pretty easy to follow:

Disable Windows Aero:
This is also a pretty decent tutorial:

Updating your Graphics card drivers to the latest version can also increase performance:

You can get the latest NVIDIA drivers from:

And the latest ATI drivers from:

You can also lower the resolution that Muvizu is running at by going to the "Prefs" menu in Muvizu - generally the lower the resolution the faster Muvizu will run.

You can also disable lighting by pressing F2, but you will probably want to turn it back on using F3 when you are dealing with your lights or making any recordings.

4. How do I upload videos?

In order to upload videos to the site you need a Muvizu account and a YouTube account. You can get a Muvizu account by clicking Join Muvizu on the Home Page or by clicking Register after clicking Log In on the Muvizu menu bar. You can get a YouTube account by going to their home page and clicking on Register on the top.

You can link the two accounts together in the "Edit Profile" section of the web site, if you have not linked them when you try to upload a video you can do so at that point.

Once you have a YouTube and Muvizu account you can upload a video through the application (Video>Upload Video to YouTube) or through the Web Site by going to People > My Profile > Upload Video.

5. I uploaded a video and it hasn't appeared on the web site

This can be due to three things:
1. If you upload a video directly to YouTube it doesn't appear on this site
2. If the video has copyrighted music on it YouTube will automatically turn syndication off and as such it cannot be shown on other websites
3. All videos on the Muvizu site are moderated, which is only done during office hours (Mon-Fri 9:30 - 5:30 British time) so if you upload a video outside of these hours it may be a day or two before it's on the site.

6. How do I add subtitles or special effects?

There are some post-processing effects available in the application which can be added by editing cameras, these include: Black & White, CCTV, Sepia, Pixelation, Old Film, Underwater, Camera Shake, Colour Tint and Negative. If you wish to add other effects you will need to use an editing programme such as VirtualDub or After Efffects.

7. Muvizu crashes on first launch

On some machines updating your Direct X Runtime to the latest version can solve launch problems - the update can be found at:

8. There are no start menu shortcuts for Muvizu

Programmes installed on a Windows 7 machine don't always get shortcuts generated for them automatically. You can create your own Desktop shortcut for Muvizu by doing the following:

Go to C:\Program Files\Muvizu\Binaries or C:\Program Files(x86)\Muvizu\Binaries if it's the 64-Bit version of Windows
Right-Click on Launcher.exe
Left-Click on Copy
Go to the Desktop
Right-Click on the Desktop
Left-Click on Paste Shortcut

9. I can't download Muvizu

If you have trouble downloading Muvizu there are a few external mirrors that you can download the installer from:


10. Muvizu crashes when I click on "Make Movie" on the menu bar

There have been some compatibility issues with the CineForm HD codec included with Sony Vegas 7. We are looking into the issue but you can either uninstall Sony Vegas 7 or download CineForm NeoPlayer 5 media player, which will update the codec and will allow you to keep using Vegas 7.

Hi Billybass,

Welcome to Muvizu!

I think you posted the same question twice. Anyway, our minimum specs are:

  • 2.4GHz processor
  • Nvidia 7800 GTX or ATI 1300 graphics card
  • 2.3GB free drive space

I can't recommend anywhere to purchase a graphics card, but if you do a quick search for it, you will find lots of online outlets.

Hope that answers your question.

Hasta pronto!
