Troubleshooting - Codecs

Definition: The compression or decompression of a media file, be it audio or video.

____________________________________________________________________________

In Muvizu terms, this basically translates to when you render out a video, a codec will compress the video file into a readable format for media playing software to read and play.

There are many a different codecs and they all do different things. Some focus on speed over compression quality, others prefer compression over speed.

There are literally hundreds of codecs in use today, some for free, some for a fee. Most you can download from the Internet. Some come packaged with software ready to use. Quite a popular bunch of codecs come as a package in the form of K-Lite, which is downloadable for free. This really covers the bases in that it gives you most of all the popular ones and is a good start before going deeper into the world of Codecs and rendering.

Lagarith Video Codec is what's called a 'lossless' codec. This means that it will render out with near no loss to the quality of what ever it is you are trying to render out. As such, it gives you quite a large file size, but if it's quality you are after, this is the route to go down.

VideoLan or VLC is a media playing software program that allows the playing of most if not all video / audio files I've ever came across. I highly recommend getting it!

Some codecs do not support some resolutions when outputting video/audio. You will most likely find that the higher the resolution, the fewer codecs will be available when rendering out video using Muvizu.

To change the codec in Muvizu, go to the Make Video tab on the top menu bar and when the new window appears, click the Advanced tab. From here you have a codecs drop down list, that if you picked a suitable resolution size, will display all available codecs to render from.
