User:Manetta/scripts/python-csv-ffmpeg-2001-triples

2001, a reassembled version made with triples

1. annotate shots from film in spreadsheat in the form of triples, and export to csv file

triple = subject + predicate + object
example: Dave + is located in + main room

00:00:00.00,00:00:07.00,space,is located in,between stars
00:00:07.00,00:01:08.00,spaceship,is located in,space,#,spaceflight,flying to,jupiter,#,spaceship,performs,spaceflight
00:01:08.00,00:01:19.00,spaceship,is located in,space
00:01:19.00,00:01:31.00,spaceship,is located in,space
00:01:31.00,00:01:47.00,dave,is located in,main room,,dave ,running at,main room,,main room ,is located in ,spaceship
00:01:47.00,00:01:56.00,other three astronauts,is located in,hybernation beds
00:01:56.00,00:02:23.00,dave,is located in,main room,,dave ,running at,main room
00:02:23.00,00:02:30.00,dave,is located in,main room,,dave ,running at,main room

2. create subtitle file from csv file

import os
import csv
import itertools

# SIMPLE SRT:
with open('2001-space-odyssey-simple.srt', 'w') as txt:
	with open('2001-chunks-annotations-01-simple.csv', 'rb') as f:
			reader = csv.reader(f)
			i=1
			for row in reader:
				start = row[0]
				end = row[1]
				x1 = row[2]
				r1 = row[3]
				y1 = row[4]
				x2 = row[6]
				r2 = row[7]
				y2 = row[8]
				x3 = row[10]
				r3 = row[11]
				y3 = row[12]
				x4 = row[14]
				r4 = row[15]
				y4 = row[16]
				x5 = row[18]
				r5 = row[19]
				y5 = row[20]
				x6 = row[22]
				r6 = row[23]
				y6 = row[24]
				x7 = row[26]
				r7 = row[27]
				y7 = row[28]
				x8 = row[30]
				r8 = row[31]
				y8 = row[32]
				x9 = row[34]
				r9 = row[35]
				y9 = row[36]
				a = i
				b = start+" --> "+end
				c = x1+" "+r1+" "+y1+"\n"+x2+" "+r2+" "+y2+"\n"+<br>x3+" "+r3+" "+y3+"\n"+x4+" "+r4+" "+y4+"\n"+x5+" "+<br>r5+" "+y5+"\n"+x6+" "+r6+" "+y6+"\n"+<br>x7+" "+r7+" "+y7+"\n"+x8+" "+r8+" "+y8+"\n"+<br>x9+" "+r9+" "+y9+"\n\n\n"
				# print c

				txt.write(str(a)+"\n")
				txt.write(b+"\n")
				txt.write(c)    
				i=i+1

1
00:00:00.00 --> 00:00:07.00
space is located in between stars
 
2
00:00:07.00 --> 00:01:08.00
spaceship is located in space
spaceflight flying to jupiter
spaceship performs spaceflight

3
00:01:08.00 --> 00:01:19.00
spaceship is located in space

4
00:01:19.00 --> 00:01:31.00
spaceship is located in space

5
00:01:31.00 --> 00:01:47.00
dave is located in main room
dave  running at main room
main room  is located in  spaceship

6
00:01:47.00 --> 00:01:56.00
other three astronauts is located in hybernation beds

3. videogrep all clips that are annotated with 'Dave'

searching with regular expressions (re) for either 'dave' and 'dave)'

import os
import re

p = "python videogrep.py --input 2001-space-odyssey-jupiter-mission.avi --search 'dave\ |dave\)' --output video-dave.mp4"
print p
os.system(p)

4. create a ordering of the grepped videoclips, export new videofile where the grepped clips are timestretched to the original shotduration

from __future__ import division 
import os
import csv
import re
import glob
import subprocess as sub
import datetime
import itertools

	for row in reader:
