Output File

After byzanz-record is finished, the recording is written to FILENAME. The format is determined by the filename extension. The following formats are supported:


Record to Byzanz' internal debugging format. This is useful for benchmarking Byzanz or if you want to convert the recording to multiple formats later. You can use byzanz-playback(1) to convert the file.


Record to a Flash Screen video. This recording method is lossless. Use it if you want to postprocess the file in other applications.


Record to an animated GIF image. Use this if you want to record a mostly static screen with a limited amount of colors, such as using a file manager or an office application. This is the default and will be used if an unrecognized extension is used.

ogg,  ogv

Record to an Ogg Theora video. This format supports audio. Use this if you want to record dynamic contents, such as video playback.


Record to a WebM video. This format consists of VP8 video and Vorbis audio streams. Use this if you want to record dynamic contents, e.g. for a HTML5 video.
