-vidi-player creates a video timeline starting from a MIDI file.
+vidi-timeline creates a video timeline starting from a MIDI file.
The video clips are taken from a "VideoFont" in which each sample clip
corresponds to a note. The samples are arranged following the time and value of
the notes in the MIDI file.
-vidi-player allows to create more easily videos like these:

* Lasse Gjertsen - Hyperactive - https://youtu.be/o9698TqtY4A
* Vittorio Saggiomo - Mario Bros Column Chromatography - https://youtu.be/mxi3z2vDV_0
Play the timeline from a MIDI file using the samples from the VideoFont:
- $ ./vidi-player.py examples/Beyer\ Op.\ 101\ -\ Exercise\ 008.midi videofont
+ $ ./vidi-timeline.py examples/Beyer\ Op.\ 101\ -\ Exercise\ 008.midi videofont
Save the timeline to be edited somewhere else (e.g. in PiTiVi):
- $ ./vidi-player.py examples/Beyer\ Op.\ 101\ -\ Exercise\ 008.midi videofont/ Beyer_008.xges
+ $ ./vidi-timeline.py examples/Beyer\ Op.\ 101\ -\ Exercise\ 008.midi videofont/ Beyer_008.xges
Render the timeline to a video file:
