Legacy ImageMagick Discussions Archive

So, the work is done! Basically I've been playing around with TimeLapse movie on my Android phone, which with ICS is really easy. Thing is that there's no ability to "drag" the shutter, so I thought maybe I could use ImageMagick to average some frames, and give a similar effect. Turns out, you can ...

that works - thanks!

The script runs fine on OSX / Lion, trying it on Linux / Ubuntu, but its not working, I get

ahhh thank you!

I created a script from your code: #!/bin/bash totnum=14 seqnum=5 num=$((totnum-seqnum)) while [ $i -le $num ]; do i1=$i i2=$((i+1)) i3=$((i+2)) i4=$((i+3)) i5=$((i+4)) convert $i1.jpg $i2.jpg $i3.jpg $i4.jpg $i5.jpg -evaluate-sequence mean result$i.jpg i=$((i+1)) done saved it as image_averager.sh ...

thanks!

Hi. After some searching I've found this forum. What I want to do is take a series of images eg 1.jpg thro 999.jpg and average them: 1 thro 5 2 thro 6 3 thro 7 and so on. I figure the script would use a command such as convert -average P2.JPG P2.JPG P3.JPG P4.JPG P5.JPG new1.jpp but I don't know ...
