First, thanks to everyone who assisted with my
previous exploits. It appears the reason I
couldn't get the command to work was I had an
earlier version of Imagemagick. Again, thanks to
all, your assistance is very much appreciated -
not least of all by the relatives who 'stare in
amazement' at what FOSS can do in the multimedia
Now, I have another goal I'm seeking assistance with.
I have two video streams. In this case (for my
trial) they're identical moving picture streams.
I've broken them down into stills:
one_000001.png to one000201.png
two_000001.png to two000201.png
I want to superimpose stream two onto stream one.
Stream two is a smaller image with a transparent
border. In effect, this will be a video playing
with a smaller version of itself in one corner.
I thought this command would do it for me:
for i in `seq 1 999`; do j=`printf %06d $i`; echo
convert one_$j.png two_$j.png -composite
but though it gives me the following message:
convert one_000001.png two_000001.png -composite
I end up with no change in the end...and the 'end
product' - convert000001.png does not exist.
Can someone please have look at what I'm doing and
provide a hint/assistance with my obviously crap
PS. I'm hopefully going to find the time to blog
my vid exploits. In the meantime, if anyone is
interested in some ideas about vid editing and
effects, I'm more than happy to help out.
