Rename AVCHD files using Exiftools

On By Hans-Henry JakobsenIn Linux, Windows3 Comments

Simple bash script to rename AVCHD/MTS/MOV files to match their recording date and time.

#!/bin/bash
if [ -z "$1" ]; then
echo "Usage: ./rename_video.sh FILETYPE" 1>&2
echo "Example: ./rename_video.sh *.MTS" 1>&2
exit 1
fi
for x in "$@"
do
exiftool '-FileName<DateTimeOriginal' -d %Y%m%d_%H%M_%%f.%%e "$x"
done
The resulting files will be named like YYYYMMDD_HHMM_BASENAME.ext ie 20120703_1635_05600.MTS

Exiftools can also be used to perform the renaming process in Windows as well using a command window

# exiftool "-FileName<DateTimeOriginal" -d %Y%m%d_%H%M_%%f.%%e *.MTS

This script has been tested on Canon Legria and on Panasonic HDC-SD800 video camera MTS-files and Nikon D7000 MOV-files with great success.

Rename files by wildcard pattern and correct the EXIF timestamp metadata

On By Hans-Henry JakobsenIn Linux, Misc, Network, Photo etc, Scripting, Web

This is a little script I’ve written to correct all my image files since the EXIF timestamp information is one hour out of sync. The filenames have been renamed to comply to the EXIF information and has to be renamed again because of the one hour scew. The filename can look something like this 20080102-1201_DSC_0910.JPG where the name is built up like YYYYMMDD-HHMM_Original_Filename.JPG
Remember to backup your imagefiles before you continue. You have been warned!

Rename files using wildcard pattern

This is the files we are going to rename

20080102-1201_DSC_0910.JPG
20080105-1923_DSC_1006.JPG
20080111-1220_DSC00189.JPG
20080122-0929_DSC00190.JPG

The mmv command is a command that lets you move/copy/append/link multiple files by wildcard patterns. It can be installed in Debian (or Debian based distributions like Ubuntu) by issuing the command

# aptitude install mmv

Now rename the files back to their original name

# mmv "*_DSC*" "DSC#2"

The result after this operation looks like this

DSC_0910.JPG
DSC_1006.JPG
DSC_1179.JPG
DSC_1302.JPG
DSC_1587.JPG

Correct the EXIF timestamp using exiv2

Next adjust the EXIF information stored in the image files to fix the one hour difference. This can be done using different EXIF tools like exiftool, but I will show you how it can be done using jhead and exiv2. The advantage with exiv2 is that it can also handle Nikon NEF files while jhead only can prosess JPG.

The current timestamp can be determined as follows

# exiftool DSC_0910.JPG | grep "File Mo"

The result in this case is

File Modification Date/Time : 2008:01:02 08:34:09

Adjust EXIF time info one hour forward using exiftool

# exiftool -AllDates+=1 DSC_0910.JPG

Other tools that could have done the job

Adjust EXIF time info one hour forward using jhead

# jhead -ta +1 DSC_0910.JPG

Install the jhead package using aptitude as mentioned earlier for the mmv package

Adjust EXIF time info one hour forward using exiv2

# exiv2 ad -a 1 DSC_0910.JPG

Rename files back to YYYYMMDD-HHMM_Original_Filename.JPG

It is now time to rename the files back to the YYYYMMDD-HHMM_Original_Filename.JPG format I used before this operation. This operation has been describe in a previous post named Rename image files according to EXIF date

exiv2 -r'%Y%m%d-%H%M_:basename:' rename $(ls D*)

The script

#!/bin/bash -x
# Needed software:
# exiftool
# exiv2
# mmv

# Script tested on Nikon D80 and Sony Cybershot DSC-W12 files

# Make a printout of how the files look like now
ls -l > repair_name_and_exif_before.txt

# Rename files to remove date formatting back to original name
mmv "*_DSC*" "DSC#2"

# Change EXIF info on JPG files (order is important)
exiftool -overwrite_original -AllDates+=1 D*.JPG
# Preserve date/time of original file when writing
exiftool -overwrite_original '-DateTimeOriginal>FileModifyDate' D*.JPG

# Change EXIF info on NEF files (order is important)
exiftool -overwrite_original -AllDates+=1 '-DateTimeOriginal>FileModifyDate' D*.NEF
# Preserve date/time of original file when writing
exiftool -overwrite_original '-DateTimeOriginal>FileModifyDate' D*.NEF

# Rename files back to date formatting (YYYYMMDD-HHMM_Filename) based on the new EXIF info
exiv2 -r'%Y%m%d-%H%M_:basename:' rename $(ls D*)

# Make a printout of how the files look like after conversion
ls -l > repair_name_and_exif_after.txt
