I want to create a gif image from a jpeg image list, everything works fine, but how can I slow the animation?
Here is my code:
<?php
exec('ffmpeg -f image2 -i thumb/%001d.jpg -vf scale=480x240 out.gif');
?>
848
From FFmpeg v2. 6 and above, it has two important filters which are very useful in creating a high-quality GIF: palettegen and paletteuse. The palettegen filter is a filter that generates a 256-color palette to be used in GIF encoding.
FFmpeg looks for image files with file names with 'img-' resulting in a two-digit number. In the command section, you will need to define a search pattern for the ffmpeg output file so that you can find the image sequence.
To slow down an image sequence, lower its framerate
ffmpeg -f image2 -framerate 10 -i thumb/%001d.jpg -vf scale=480x240 out.gif
