Troubleshooting - Time and video size limits

There are a few limits on time and size within Muvizu, but there ARE workarounds and ways to avoid this problem.

Time Limits

Muvizu has a time limit of 20 minutes.

This is to do with the AVI 1.0 that Muvizu uses; which links up to size limits. The recommended is to try and avoid using up the full 20 minutes per scene - that's a lot of render, and your shots will start to get fairly repetitive. The best way is to set out what it is you want to do - how long do you expect your production to be? Break it into scenes and events, then make each scene a bit at a time. There's ways for you to link these up later, which you'll find if you scroll down to Video Joiner.

Size Limits

The size limits are 2gb - working out to 20 minutes recording time.

This is why it's recommended you don't use them all in one go. The great thing about Muvizu is you're able to make as many videos as you like, and then you can put them all together. You can make a one hour movie using 5 - 10 minute scenes, which you can then join together, and edit using other software. You'll get the best, most professional looking video in the end, with plenty of variation, and you won't have a computer bogged down by render time.

Recommended Output

There's a few different outputs that Muvizu supports; you can export your video as a basic .AVI file, or you can output it as a Targa sequence.

Targa sequences, in a nutshell, break your video down - frame by frame - into high resolution images. Programs can then re-sequence these images in the correct order and, with the use of video editing software, you will be able to easily edit your video frame by frame.

Another option is to use codecs. The job of a codec is to compress your video, making them quicker to render out at the end of your recording, but without compromising any of the quality. These are great for anyone to use, and highly recommended to users. For a list of some great codecs, and how to put them into use, you can check the following page here on our wiki.

Video Joiner

Within Muvizu, there is a specialised Video Joiner tool. This is purposely made for pulling your Muvizu videos together and making one, seamless video that you can then edit, without having to run each through another editing program. You can find it in your start menu; just go to Start > Muvizu:Play > VideoJoiner. Note, however, that Video Joiner only supports a .AVI format - if you're looking for more extensive results, then see VirtualDub.


VirtualDub is a nice, basic program which you can use to do the same job as Video Joiner, however supporting a greater number of video formats. VirtualDub allows users to pull videos together, clip and edit them as required, cut off sections you don't want or need, and then save them out as an .AVI file.
