   alias ff='ffmpeg -hide_banner'

  -
  -FFmpeg can be installed with `cinst -y imagemagick`.
  +alias exif='exiftool.exe -G1:2 -s -a'
  +----
  +
  +FFmpeg and exiftool can be installed with `cinst -y imagemagick exiftool`.
  +Meaning of exiftool switches is this:
  +
  +* `-G1:2` shows group names for each tag, family number 1 means *specific
  +location* and 2 is *category*;
  +* `-s` printed tag names have no spaces and can be used as options;
  +* `-a` shows all the tags, even duplicated ones.
  +
  +See more about exiftool https://exiftool.org/exiftool_pod.html[options]

  +== Quick overview of video metadata
  +
  +To quickly see FPS and lenses used for videos during the day use:
  +----
  +exiftool -q -s2 -videoframerate -lensid *MVI* | sort -u
  +----
  +
  +Option `-q` suppresses output of file names, `-s2` makes the output more compact
  +and `sort -u` sorts the output leaving each unique line only once.
   
   == Fixing videos for Vegas/Movie Studio
   
  
positive.code: 
  Vegas can now import it and the file also gets considerably shorter without visible loss of quality.
  At least for that phone (results probably may vary).
  
  == Canon video conversion
  
  
negative.code: Usage of `ffmpeg` is complemented with `exiftool` to preserve the important metadata (creation date, camera and lens).
  The following script does the job:
  
  .canon-video-conver.sh
