Timelapse from imges with FFMPEG and ImageMagick

timelapse.cmd

REM Batch file for Windows only
REM This script takes images from a 

SET EXTENSION=jpg

REM This is NOT an usual glob pattern.
REM This example matches 4 digits, like "DSC_0243".
SET PATTERN=DSC_%04d"

ffmpeg.exe -r 24 -i %PATTERN%.%EXTENSION% -s hd720 -vcodec libx264 out.mp4

REM Some additional information retrieven from this gist: https://gist.github.com/porjo/3e4b182089c430a54a64
REM Thanks to the initial contributor!

REM -r 24							- output frame rate
REM -pattern_type glob -i '*.JPG'	- all JPG files in the current directory
REM -i DSC_%04d.JPG					- e.g. DSC_0397.JPG
REM -s hd1080						- 1920x1080 resolution

REM Add the following after -vcodec libx264 to achieve better quality output
REM -crf 18 -preset slow
