What would you like to do?
Timelapse from imges with FFMPEG and ImageMagick
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

/**
* This script converts all images to resize them & make them a bit lighter for the final timelapse.
* It executes ImageMagick once per image instead of using commands like "magick convert *.jpg ..."
* because it saves LOT of memory & performances, is way faster!
* Will always convert to JPEG for maximum space.
