Comment (by adaerr):

 Thanks for the comment. Although using ImageMagick to pipe the images into
 ffmpeg is indeed a workaround I should have mentioned, it works only for
 not too large files. The variant I use is

 `convert foo.tif ppm:- | ffmpeg -f image2pipe -framerate 15 -i - [...]`

 ImageMagick was not designed for processing long image sequences - though
 it has some animation support for gif etc - so this is slow and fails for
 large files: `convert` loads images into memory (can be extended by use of
 tmp dir and tuning magick's configuration to some extent) before
 outputting data, so memory usage increases with file size. Note that the
 limit file size is a fraction of the available cache size: the internal
 representation of images may have 16bit depth per channel, so 8bit gray is
 stored as 64bpp RGBA in memory/cache.
