Many LTR postprocessing tools generate a series of images (file-001.png, file-002.png, ... etc). When viewed in sequence, these images form a movie or animation. This page documents how to merge these images into a movie which may be played on a variety of players:
Our favorite movie encoder is ffmpeg with the H.264/x264 MPEG plugin/codec. We have found that H.264 offers the best compromise between image quality and movie file size.
port install x264 ffmpeg
Assume you have images:
image001.tiff image002.tiff image003.tiff …
and you wish to generate an animation (movie.mp4
). Here's the command you would use:
ffmpeg -f image2 -i "image%03d.tiff" -pix_fmt yuv420p movie.mp4
