Hello,

We are pleased to announce a new release of the ARENA motion capture software, version 1.1.034 beta 1 is now available for download!

This release includes support for two actors, improved tracking and the ability to use up to 24 cameras. We hope you enjoy the upgrades.

note : in order to achieve good tracking results, we only recommend using the two actor support with at least 12 cameras.

Outstanding Birch and all involved - thanks for this release!

Birch,

This release seems to take alot long to calculation the calibration(about 50 mins, using slow, 800 pts). Is that expected?

Mark,

I don't think there were any changes to the calibration which would cause it to take longer to process. Is the long calculation time occurring every time you calibrate now?

I only tried it once and I did get a good result at the end, so I don't want to redo it yet. The next time I calibrate I'll compare the times and let you know. Thanks.

Mark:

FYI, you can always load in a previous calibration file, just save the new one with a different name, you can have several for the same camera config and load whichever one was the best.

Update :

The beta period proceeded smoothly so we are moving the 1.1.034 release of Arena to final with no changes.
