Scrolling sheet music with Piano Accompanist

some weeks ago, first time play violin outdoor alone that a few people visit.

it makes me decide to produce some time-based auto scrolling sheet music with audio
and playback in tablets on music stands.

here's 2 samples clip around 60 secs.

All done in PC, intel pentium g620, 16gb ram, windows 7

software involved.
-- Adobe PDF Reader - Ctrl-Shift H, auto-scrolling,
speed control by keyboard up/down arrow or numeric 0,1,2,3...

-- Musescore 2, produce 2 audio files, (just my case, 1 for Piano, Violin and supporting
tracks, another one only start indication and Piano Track.

-- Camtasia Recorder, Screen Capturing to produce avi file.

-- GiliSoft Video Editor 7, add audio to avi file and output to MP4 format.

Notes about:

1. PDF file,
- trim/cut the unnecessary remarks
- insert a blank page to end of score

2. Screen Capture Software
Record Size around 1000 x 680, 25fps
- may recording audio and scrolling pdf at the same time,
(my pc installed creative omni usb sound card which support 'what you hear audio out'

Now i could play violin anywhere, no need to bring with actual PIANO.
