[Insight-users] Re: format conversion

[Amadeus]

Thanks for the answer. I also found the solution, which I'll post, in case
other people might benefit from it. 

I work exclusively in Linux and one can use mplayer - the mother of all
multimedia tools - to dump each frame in a movie clip. MPlayer understands
just about any format under the sun and can use just about any codec as
well. E.g. to dump each frame in an avi clip to a separate png image

mplayer -vo png movie.avi

To see to what other formats one can output the frames to, 

mplayer -vo help


Then, the frames dumped by mplayer can be put together into a volume
using ImageSeriesReadWrite in InsightToolkit-2.0.0/Examples/IO/.

Of course, in Linux and other unixes the shell understands wildcards, 
so with minor changes, it ImageSeriesReadWrite can be modified to work
like this:

ImageSeriesReadWrite frame*.png output.mha   # or e.g. output.mhd

The input frames need not have the names that the original
ImageSeriesReadWrite expects.
