  • Changed value of field process_step to The abstract and the script were prepared as markdown text files. They were converted to HTML and opened by LibreOffice Writer before they were exported as PDF files. The slides were prepared, and exported as a PDF file, by using LibrOffice Impress. The slides were converted to a sequence of JPG image files (1600 x 1200) in LibreOffice Impress (Version 5) with the "Export As Images" plug-in. The title slide was modified on August 12 and exported as a JPG image file in LibreOffice Impress (Version 6). The script was recorded as WAV files, one WAV file for each JPG image. For each slide, the audio was converted from WAV to M4A format, and synched with the JPG image to make a MP4 video by using the following ffmpeg command (here slide 1 is used as an example): > ffmpeg -loop 1 -i 1.jpg -i 1.m4a -c:v libx264 -c:a copy -shortest 1.mp4 The 22 MP4 files '1. mp4', '2.mp4', ..., '22.mp4' were concatenated to make a final output video file 'out.mp4': > ffmpeg -f concat -safe 0 -i fileList.txt -c copy out.mp4 while the file 'fileList.txt' includes the following lines: > file '1.mp4' > file '2.mp4' ... > file '22.mp4' All files were prepared in Debian 10.10 (or older versions) with Cinnamon 3.8.8 (or older versions). in Experience in Moving Toward An Open Repository For All
