Mavica tips

Converting .411 files

These are thumbnail files. I’ve had luck using XnConvert to do the conversion.

Field vs frame

Field: slightly worse image, no interlacing artefacts

Frame: slightly better image, interlacing artefacts (moving things get shredded)

Battery stuck

Put a ribbon or floss around the battery first so you can pull it out later.

Applying EXIF

exiftool \
  "-datetimeoriginal<filemodifydate" \
  -make="SONY" \
  -model="MAVICA MVC-FD7" \
  -EXIF:OffsetTime*=+8:00 \
  .

If you have a GPS track

exiftool -geotag track.gpx \
  . \
  -api GeoMaxIntSecs=1800 \
  '-geotime<${DateTimeOriginal}+08:00'
