Hi there,
I encountered a nice piano learning video including hands and animated
keys, but since it is playing at original speed it is way to fast for
me to learn that song. In case anyone is interested, it's this video
and I think it's rather nicely done (don't hate me for the music :P):
https://www.youtube.com/watch?v=Ej6MF5KjuOc
I found one way which sort of works (after settings LADSPA_PATH) but it
sounds quite horrible. Is there a better way to do this?

Is there a stretchplayer for video?

Cool request! I didn't care about, resp. didn't clicked your links, but
I'm aware that there are such videos available since years. A friend, a
finished masterclass guy showed me those videos, but I'm even not a
piano beginner, I'm a guitarist ;). I never tried to learn from those
videos.
:)

PS: It depends on what you want to learn, but for around 3,- € there are
amazing iThingy apps available. Books for around 80,- € aren't that
flexible and books won't produce audible music output.

VLC can do that, there's no nice GUI element for speed control, but a submenu in
"playback" menu... don't expect high quality either.

both mplayer and VLC provide such controls, it allows to slow

A line like this works but requires to set the pitch beforehand

I wouldn't have suggested it if it wouldn't timestretch (while retaining pitch), I

Hi Edgar,
it was a mistake on my side. There is an option that needs to be
enabled. It can be found under Tools -> Preferences -> Audio and there
in the effects section is an option called 'Enable Time-Stretching
audio'. If enabled the pitch is corrected.

Don't know about slowing this down ...
But, that is a really hard way to learn something. Much easier to learn to
read music and learn the basics of piano playing!

It won't show you what a video with animations does show you, when it is
done by masterclass folks. And this is not only good for masterclass
people who share their knowledge with other folks on the same level,
it's also good for beginners with artistical gifts, who don't think in a
way to learn in "school style" (left vs right cerebral hemisphere ...
especially for people who can't read music, e.g. regarding to perception
disorder, such as dyslexia, when the notes become ants running around
the sheet). And as already pointed out, books or paying a teacher is
muuuuuch more expensive than a video or iThingy app.

PS: Perhaps you should subscribe to receive Tracktion advertisements. I
directly filter them to my junk folder, but I read them, to follow the
development. A few days ago I received an advertisement about an
included software for pitch correction editing, an award winner rival to
the Antares thingy. We never know, perhaps in a few month, it would
provide video handling too.

The audio filter `scaletempo' should be acceptable for your purpose:
mplayer -af scaletempo -speed 0.5 video...
it's a little better:
mplayer -af scaletempo=stride=50:overlap=.25:search=20 -speed 0.5 video...

There is a link to the Midi file. You
can play a Midi file at any speed and look at the piano roll.

I had overlooked the midi file and sheet there. It should be of great

While it sounds like you may have found something that gets the job done, I
got better quality (to my ears) than mplayer or VLC like this:
$ ffmpeg -i careless-whisper-piano-orig.mp4 -an -b:v 1022k -vf
"setpts=(1/0.25)*PTS" careless-whisper-piano-tutorial.mp4
$ ffmpeg -i careless-whisper-piano-orig.mp4 careless-whisper-piano-tutorial.wav
$ rubberband -t4 careless-whisper-piano-tutorial.wav
careless-whisper-piano-tutorial-stretched.wav
$ ffmpeg -i careless-whisper-piano-tutorial.mp4 -i
careless-whisper-piano-tutorial-stretched.wav -c:v copy
careless-whisper-piano-tutorial-stretched.mp4
It took a while (probably 20 minutes on my underpowered laptop) but I think
this is the method I'll be using the next time I want to learn a part. Not
really a fan of this particular song, but stretched out 4:1 it sounds kind
of mellow and what artifacts I hear just make it a little bit trippy, while
making any Richard-Clayderman-esque parallel-6th abuse and other
easy-listening cliches in this arrangement less noticeable. So, that's an
improvement.

I finally came around to try this method and it sounds indeed better
than the on-the-fly methods in VLC and so on.
I find it funny that, according to Wikipedia, George Michael himself
doesn't particularly like the song (at least the lyrics). I'm not a
George Michael fan nor do I particularly like easy listening music,
quite on the contrary, but it's a nice enough song and I figured it's
not too hard to learn. Once I know how to play it I'll play
with it and interpret it anyway. Let's see how that will turn out :)
