Hi Jack.

Adding a score to a video. Here's an example

https://www.youtube.com/watch?v=HCZJ203ikoo

I hadn't thought of it as an animated video. It's a series of cleaned up screen shots of the score, about four bars at a time, each image lasting as long as it takes to play.

I'm using a recording I made back in 2011, edited in a program called Audacity and exported as an mp3 file. You could use the music generated by the score itself.

The score is made using Musescore. I do the notation first and then copy and paste the score into the tab. It always needs a good bit of editing to get the fingering correct.

I get the first line of the score large enough so that the first four bars (usually four) look good across the whole width of the screen and press the 'Print Screen' button. I then do it again with the next four bars and keep doing that for the whole score.

I edit the screen shots in a program called Pinta (anagram of Paint), which is very similar to the Windows Paint program. It has all the basic video editing tools and, at 1200 times magnification can show the image at a pixel by pixel level. It also has rulers.

Combining the pixel view with the rulers it is possible to get the title dead center. Once the title is centered the score is moved to where I want it and a note is made of the top and bottom lines position. A check at 100% magnification and that gets saved as 'Frame 1'.

Leaving Frame 1 still open, I start another version of Pinta and open the next screen shot. I copy just the score from that into Frame 1 and make sure it is at the same height and centered. This is then saved as 'Frame 2'. Repeat that process for the rest of the score.

I put the recording and images together in a program called Kdenlive. I import the audio first then the frames one at a time. Each frame is dragged into position above the audio and stretched so it lasts as long as the music it represents. This would be a lot easier if I could expand the view of the audio track. It may be possible but I haven't figured it out yet.

The whole thing is rendered as a .avi file and can then be uploaded.

Looks like Kdenlive (the thing that's doing the heavy lifting in your workflow) is a Linux utility.

What else does the same job, freeware or not?

The Wiki on Kdenlive suggests that it is available for Windows but not which versions. This link

https://filmora.wondershare.com/video-editor/free-video-editing-software-windows.html

suggests Windows Movie Maker, amongst others. and gives links to download.

There is another I've used called Open Shot but I found Kdenlive gave more details visually of the audio track so it was easier to position the images.

Kdenlive is a KDE program. I believe KDE4 was available for other platforms (although I guess it would be a rather heavy install, etc.) but I don't think this is the case for the current Plasma5.

I'd guess one could try any video editor?

It's a laundry chute, friend and neighbour.
Thanks for making me laugh this rainy morning.

I've been away at a festval for the last three days. I'm not sure where the last few posts have taken us but I'm now back if anyone wants queations answered. A 'Tech' prefix is OK by me.
