beamer memo

• Compiling beamer (here (Jpn) was very helpful)

  As with latex, it is very easy if you use lualatex for Japanese and pdflatex for English. If you really don't want to use lualatex or pdflatex, especially if you put movies in beamer's multimedia package, compiling via dvipdfmx doesn't work very well, so you can make a pdf via ps.

                  platex hoge.tex
                  platex hoge.tex
                  dvips hoge.dvi
                  convbkmk -g -O hote.ps
                  ps2pdf hoge.ps

  It might be safer to make a script for compilation or something?
  Personal settings for using lualatex

                  \documentclass[unicode,xcolor={svgnames},aspectratio=169]{beamer}
              
                  \usepackage{luatexja}
                  \usepackage[ipaex]{luatexja-preset}
                  \renewcommand{\kanjifamilydefault}{\gtdefault}
              
                  \usepackage{geometry}
                  \geometry{left=0.1in,right=0.1in,top=0cm,bottom=0cm}
              
                  \usepackage{xcolor,colortbl}
                  \usepackage{amsmath,amssymb}
                  \usepackage[absolute,overlay]{textpos}
                  \usepackage{tikz}
                  \usepackage{ascmac,fancybox}
                  \usepackage{mathtools}
                  \usepackage{cmbright}
                  \usepackage{graphbox}
              
                  \usepackage{pdfpcnotes}

  pdflatex in Englishin English, the fifth line is not necessary

• pasting a movie

  lualatex and pdflatex do not even need to import the multimedia package in the first place.

                  \href{run:hoge.mp4?autostart&loop}{\includegraphics{hoge_tn.png}}

  The latter half of the image is a so-called thumbnail, which unlike PowerPoint is always necessary. If you have not created thumbnails, you can use ffmpeg to create them quickly.

                  ffmpeg -r (frame rate of video) -i hoge.mp4 -ss 0 -t 1 -r 1 -f image2 hoge_tn.png

  However, this method will not work with evince or okular. Use pdfpc honestly.

• Creating slide notes in pdfpc

  Slide notes can be created by a text file with the same name as the pdf file and the extension pdfpc. The contents of the file are

                  [font size]
                  17
                  [notes]
                  ### 1
                   Hello everyone. I am going to give a presentation now
                  ### 2
                   This is what I am going to present now
                

  like that.
  The latest version changes itself when you start pdfpc even if you make it like this. What an unnecessary thing to do.
