Help Renaming Video Files

[dwlima]

I have hundreds of MTS and AVI files since 2000 and would like to rename them in the following manner based on the date created: DD-MMM-YYYY HH.MM.SS_X; where X begins at 1 and increments by 1 if there are dublicate date/time stamped videos.

Ex: 19-Nov-2002 08.12.30.avi, 19-Nov-2002 08:13:30_1 and 19-Nov-2002 08:13:30_2

Someone previously wrote the following script for me, and it works great for photos. It uses EXIV2 to get the image date created info. I have tried to understand the script, but am struggling. The video files I have can use the date modified since I have not modified them since I filmed them.

Any help would be hugely appreciated.


#!/usr/bin/env python

import os
import stat
import pyexiv2
import time

directory = '/home/david/Desktop/test'

# For every file in the directory
for filename in os.listdir(directory):
filepath = '%s/%s' % (directory, filename)

# If it's not a file, ignore it
if not os.path.isfile(filepath):
continue

# Get creation time. If it cannot, it will be "Unknown"
try:
metadata = pyexiv2.ImageMetadata(filepath)
metadata.read()
tag = metadata['Exif.Image.DateTime']
creationTime = time.strptime(tag.raw_value, '%Y:%m:%d %H:%M:%S')
creationTime = time.strftime('%d-%b-%Y %H.%M.%S', creationTime)
except Exception, e:
creationTime = 'Unknown'
print 'ERROR: %s has no exif creation time' % filename


# Get file extension. eg. file.jpg -> jpg
extension = '.'.join(filename.split('.')[1:])

# Get filename
newFilename = '%s/%s.%s' % (directory, creationTime, extension)

# Check if it already exists
if os.path.exists(newFilename):
i = 1
while (os.path.exists(newFilename)):
newFilename = '%s/%s_%s.%s' % (directory, creationTime, i, extension)
i += 1
print newFilename
#os.rename(filepath, newFilename)

I finally figured it out:

#!/usr/bin/env python

import os
import stat
import datetime

directory = '/home/david/Desktop/Test'

# For every file in the directory
for filename in os.listdir(directory):
filepath = '%s/%s' % (directory, filename)

# If it's not a file, ignore it
if not os.path.isfile(filepath):
continue

# Get unix creation time
unixCreation = os.stat(filepath).st_mtime

# Convert to string. eg 1311602304 -> 26-Jul-2011
dateStr = datetime.date.fromtimestamp(unixCreation).strftime ('%d-%b-%Y')
timeStr = datetime.datetime.fromtimestamp(unixCreation).strf time('%H.%M.%S')

# Get file extension. eg. file.jpg -> jpg
extension = '.'.join(filename.split('.')[1:])

# Get filename
newFilename = '%s/%s %s.%s' % (directory, dateStr, timeStr, extension)

# Check if it already exists
i = 0
while (os.path.exists(newFilename)):
newFilename = '%s/%s %s_%s.%s' % (directory, timeStr, dateStr, i, extension)
i += 1

#print '"%s" -> "%s"' % (filepath, newFilename)
os.rename(filepath, newFilename)
