Would anybody happen to know what is the easiest way in IDL to create
animations in the form of mpeg or avi files from a series of still
images in png, jpg or other format. I see there are some licensing
issues where you have to pay money for an extra licence to make mpeg
files. Is there perhaps some other software package that dosnt cost too
much that can make the animations from the still images, which could
then be run on say windows media player or other commonly used player.

Thank you,
Neil

Yes, I think Motion JPEG-2000 is going to become useful, when the rest
of the software world catches up with the pioneers like IDL. But note
that there are already quite a few ways of storing an animation
losslessly. They include:

- FLC (8-bit colour only)
- Multi-frame TIFF files
- Sequences of PNG files
- Lossless AVI codecs like Huffyuv, Lagarith and MSUD
- The plain old Microsoft RLE and Video 1 AVI codecs are as
close to lossless as anyone needs if you set the quality
level high enough. They support 8-bit and 16-bit colour
respectively. They are supported by lots of players.

Videomach does the job much more quickly and easily than IDL. How much
is your time worth?

Note that I'm talking about converting images that are already in files
into movies, or more generally converting between movie formats. If your
images are in the form of IDL graphics sequences, then you first need to
get them into an image format and the IDL-to-AVI converters are the way
to go. Videomach can still be useful for later manipulations though.

that idl 6.3 includes mjpeg2000 read and write functionality.
the cool thing about mjpeg2000 is that you can create lossless
animations. lossless is works well when you want to preserve
the original data in a compressed format. lossless also works
well when text is involved...the text does not become blurry like
it does using mjpeg.
