Galea - Merge video clips into 1 video with transitions

Galea is a simple, open source, command line programme to merge various video transitions together


These motorbike videos have been created with Galea.


The code is hosted on github. just download and run ./ Download the latest zip file here


Galea was created because I felt most video editing software was too complex, especially when I just want to stitch some videos together, so I tried to make Galea use sensible defaults and not require much thinking.

You can call it with just: video1.mp4 video2.mp4 video3.mp4

And it will produce a file called video.ogg with each file stiched together with a 0.5 second transition between the lot.


Usage: [options]

  -h, --help            show this help message and exit
                        prefix for filename to save output to
                        Length in seconds of transition (default: 0.5)
  -m MUSIC, --music=MUSIC
                        File to use as music backingtrack. default: no music
  -s MUSIC_START, --music-start=MUSIC_START
                        Start the music file playing at this point, not the
                        start of the music
  -f FORMAT, --format=FORMAT
                        Type of video format output
  -v MUSIC_VOLUME, --music-volume=MUSIC_VOLUME
                        Multiply the music volume by this. 1.0=leave same
                        (default), 0.5=half as loud

Video Formats

By default it creats a OGV file, at a video high bitrate, i.e. the file will be quite large. You probably want to convert that to a smaller file. I used the OGV as a decent intermediate file format, and didn't want to lose any quality, so I didn't change the options.
