Compressed .AVI

lechristophe
Dear listers,

I just got a bunch of .avi files that are an output from a Matlab routine
that I didn't right, and that I don't even have access to. I would like to
further process the images (i.e., stitch several movies in parallel), but
when I'm trying to do an Import/.AVI I get an error about ImageJ not being
able to open compressed avi. Is there a more versatile plugin that would be
able to open such images ? Or alternatively, is there a good free software
to know exactly what kind of file is this .avi and convert it to an ImageJ
readable format ?

Thank you for your advices,

Christophe Leterrier

Hi Christophe,

Bio-Formats can read AVI compressed with the Microsoft Run-Length
Encoding (MSRLE) and Microsoft Video (MSV1) codecs. The JMF Movie
Reader plugin (http://rsb.info.nih.gov/ij/plugins/jmf.html) can handle
Cinepak and JPEG codecs. Otherwise, if your movie uses something else,
it will likely be easiest to use some kind of transcoding software to
uncompress the video first.

On Windows, you can find out a lot of details about your file,
including which codec it uses, with the GSpot Codec Information
Appliance (http://www.headbands.com/gspot/).

As for a transcoding application, there are a large number of them.
You could try VirtualDub (http://www.virtualdub.org/) or transcode
(http://www.transcoding.org), or just Google around.
