Hello,

I create image sequences for video with a lot of frames. I use ImageMagick in command line to check the integrity of each frame with a loop. But it's very slow on big frames (HD TGA, 1920x1080, about 6 Mbits). So it's running at about 2 images per second.

How can i speed up the process? Is it possible to launch the work on all the processors of the workstation?

Thank you for your help.

Without an example of what you are actually doing it is hard to say what speed up we can suggest!

By default individula operators within IM will make use of multiple processors. However if you want to parellize multiple operations (runnign multiple convert commands), you may want to turn of threaded processing.

For some basic speed up tips look at...
