Animations

For autocropping:

for i in `ls *jpg`; do convert -trim $i out_$i; done

But if the size is not the same for all images, the encoding could fail, in this case, force the cropping:

for i in `ls *jpg`; do convert $i -crop '990x870+5+35' out_$i; mv -f out_$i $i; done

Gif files can be animated using gifsicle [1]

gifsicle --delay=10 --loop *.gif > anim.gif

Convert from ImageMagick also does the trick:

convert -delay 10 -loop 0 $(ls -1 *.png | sort -V) animated.gif

The listing is such that it normal-orders the files, which is usually what one wants to do.

mpeg can be generated with a command like:

mencoder "mf://*.jpg" -mf fps=10 -ovc lavc -o ./dest.avi

with 10 frames per second.

avconv is also popular. To do lossless compression, you may try:

avconv -f image2 -r 30 -i %03d.png -vcodec qtrle -pix_fmt rgb24 -t 15 qtrle-30fps-rgb.mov
