Re: Teaser: Animated Lilypond Scores

[Valentin Petzel]

Hello Henning.

thank you for the tip, but the problem is not that Inkscape cannot handle OTF 
features but that the Lilypond svg backend does handle them.

Re: Red dot before all notes

[Jacques Menu]

Hello,

Using ". “ instead of ". “ in the original solution moves the dot apart.

You might want to look into ConTeXt LMTX, it uses a SVG-to-Metapost 
converter written in Lua to create PDF and supports all the OTF features.

Re: Teaser: Animated Lilypond Scores

Huh, this is quite an amount of replies.

The script basically works by inserting information about the current beat as 
well as the timing into the score, which is then output to svg. We then parse 
these svg files to retrieve this information and remove the codes. These 
cleaned svgs are then converted to png files. These are then turned into frames 
and sent to ffmpeg. Converting the svg is done using inkscape for now, as this 
one handles ligatures and such stuff. Of course this means that we lack otf 
features for now.

Currently this thing supports multiple pages as well as automatic scrolling 
(both vertically and horizontally). Support for repeats, jumps and omissions 
will eventually come, as well as handling of multiple scores (which I’ll 
implement by using score IDs.

Alignment is done by setting the context property Score.timestep to the time 
in seconds. For jumps and repeats this will probably at some point allow 
giving a list of timestamps, one entry for each time the part is played.

@Paolo: I started this because I just couldn’t get ly2video to handle timing 
well (that one uses a relative approach, so timing is adjusted by bpm. This is 
of course extremely volatile, as errors can sum up. My script instead aligns 
by the actual timestamp.). Also ly2video has to compromise on quality and 
speed as it works mainly on png. And yes, I’m going to publish the script once 
I’ve got it in a better shape. So far I’ve only been working on it a few 
hours.

@Kira: Glad you like it!

@Kevin: Syncing up to MIDI is surely possible. My script is fast enough to 
make display in realtime viable (and if we can modify the viewer of 
frescobaldi to draw additional stuff we can get even faster. So it should very 
well be possible to do something like this for Frescobaldi.

@Hendur: This script is written in python so far. Currently it relies on the 
output of Lilypond, eventually it should do stuff like running Lilypond and 
injecting relevant Lilypond code automatically.

@Mario: Yes! I will not give a more detailed explanation than the above for 
I’m a bit too tired now. I’ve currently just spend a few hours on this thing, 
once it is in a better shape I will make this available.

@Tom: No, I’m not asking for feedback at this point.  I’m just letting you 
know that I have something like this in the works. Once I have this far enough 
to be usable I’ll be open for feedback.

@Kenneth: I don’t think you need to wait long, but I need to add some 
logistics first.

Cheers,
Valentin

Nice! Before, we had 2 different methods for generating video from LilyPond.

ly2video, by Adam Spiers, which makes a scrolling score.



MKVIDEO, by Knut Petersen, which makes a still score with notes changing 
color as they are played.








Now the video you've produced has a moving blue bar reminding me of the 
MuseScore software's playback function.


I think ideally these things would be combined into a best-hybrid 
product that's officially maintained within LilyPond or along-side as 
Frescobaldi is. Or whatever best serves the community around it.


As LilyPond moves towards using the cairo library for graphics output, I 
hope these video output methods (or something like them) is available 
beyond the transition. Video scores can be great learning aids for 
complex choral works. (Reminds me, I told someone I could get them one 
of "Worthy Is The Lamb" from Handel's Messiah by spring...)

Bravo! Encore! Loving the "follow the non-bouncing line" -- as opposed
to the older "follow the bouncing ball".

Re: Teaser: Animated Lilypond Scores

[Kira Garvie]

I love it! That is amazing, and no need to apologize for your piano
playing. The scrolling scores are extremely helpful for score study!

Teaser: Animated Lilypond Scores

Hello Pondmates!

I have created an experimental script to turn a Lilypond score into an animated 
video. Here is a little teaser:
https://youtu.be/oFFm7FcFaLA[1]

Just a trigger warning: This contains bad piano playing!

Cheers,
