| The new way of converting JPEGs to MPEGs |
I wrote the JPEG to MPEG howto a while ago, and used the best tools that I could find at the time. It was a complicated, evil process, but people still email me a couple of times a month and thank me for it. I think they'll like this way even more.
For my PhD, I'm taking large numbers of images and displaying them one after another on a monitor so that I can capture the images with a webcam. The reason is a little convoluted, so let's settle for I'm trying to see what sort of image distortion the webcam will impose. I figured that the best way to do this was to simply have a MPEG2 movie that was the images, play it on the machine, and then point the webcam at the monitor. At about this time in a twist of wonderful fate I discovered I could do this in a simple command line with ImageMagick. Let's see how (all of these instructions are based on Debian unstable, but should work anywhere):
Install ImageMagick
apt-get install imagemagick
Install mpeg2vidcodec
This isn't packaged for Debian, but I've put a request for package bug in. Do this:
wget ftp://ftp.mpegtv.com/pub/mpeg/mssg/mpeg2vidcodec_v12.tar.gz tar xvzf mpeg2vidcodec_v12.tar.gz cd mpeg2 make cd src/mpeg2dec cp mpeg2decode /usr/local/bin cd ../mpeg2enc cp mpeg2encode /usr/local/bin
Do the thing
So, now we can do the thing. In this instance we have a bunch of TIFF files we want to turn into an MPEG2 video.
convert *.tif foobar.mpg
And we're done. Nice, isn't it? [tags: jpeg mpeg movie convert imagemagick phd tutorial howto opensource linux video]

Hey, thanks! My computer graphics class is doing some image-morphing experiments, and I've been searching for a while online for good jpg2mpg
conversion software. I've shown them ImageMagick already, and this is very excellent---works fine under Fedora Core 3.

Yay, thanks! This works on Mac OS X 10.4.5.

Thanks! I have thousands of JPGs to convert to usable MPGs and this should be it. I was hoping to do the conversion under the linux platform!

Hello,
I allso tried convert like it is decribed here, but it did not work:
I compiled the mpeg2videocodec as described under my Debian(testing) and tried to convert a jpeg from my digital-camera, I also got a test.mpeg-file, but in every player I tried only a blck screen was shown, nothing to see of the original jpeg, not even for a short time.
beye

Mpeg2vidcodec isn't available at the mpegtv ftp repository, but you can get it at ftp://ftp.imagemagick.org/pub/ImageMagick/delegates/

This worked for me, except how do you make the JPEG stay up longer than 1 frame? I need them to be 10 minute MPEGs if possible...

Hello,
Thanks for the tutorial, i need some suggestion, i need a tool to convert jpgs to mpeg for my embedded system. I tried ffmpeg, but it is difficult to cross compile, what about imagemgick ? do you have any idea ?

You are the man. Nobody else is the man.
I was going crazy.
