hpr1449 :: Timelapse Video

Released on 2014-02-20 under a CC-BY-SA license.

A quick introduction to timelapse video and some of the tools used in linux to help create them.

cd to dir that holds the images

Create a directory called resize and run

"mogrify -path resize -resize 1920x1080! *.JPG"

If you need to Deflicker your images place the script in your resize directory and run

"./timelapse-deflicker.pl -v"

This will create a dir called deflickered

If you use mencoder to create your video you need to use ls and make a text file with the files listed in sequential order

"ls -1tr | grep -v files.txt > files.txt"

then

"mencoder -nosound -noskip -oac copy -ovc copy -o outputfile.avi -mf fps=25 'mf://@files.txt'

if you use ffmpeg something like this should get you out of trouble, though your files need to be named in sequential order starting with img(number 1 2 etc).jpg

"ffmpeg -f image2 -i img%d.jpg -vcodec libx264 outputfile.mp4"
