  -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.
  +

  +== 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: Usage of `ffmpeg` is complemented with `exiftool` to preserve the important metadata (creation date, camera and lens).
  The following script does the job:
  
  ----
  #!/bin/bash
  #
  
negative.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).
  Alternatively, use the conversion script below, potentially with `Q=...` prefix.
