<p>Hi james, can you copy exactly the color coding string and email it? In general, fview records in color just fine, just the display doesn't (yet) show color.

<br>----- Original message -----
<br>> We need to record video of ant colonies in FView that will be used for
<br>> two things, 1) Ctrax tracking, and 2) 'manual' frame by frame
<br>> behavioral observations.  That second project requires that the ants
<br>> be individually marked with color dots -- so we need to record color
<br>> video.
<br>>
<br>> We're using a PtGrey Flea2 and Ubuntu 10.04 and all the latest
<br>> releases.  When initializing the camera and choosing a ...MONO8 video
<br>> mode, it works, but this is grayscale.  We get the following error
<br>> message when trying to initialize the camera using any RGB video mode:
<br>>
<br>> Error opening camera

<br>>
<br>> Is there any chance there is a quick fix for this?  If color recording
<br>> is not possible with this camera in FView at this time... can you
<br>> recommend any other programs?  If we absolutely had to, we could
<br>> record grayscale video in FView for use with Ctrax and then record a
<br>> second video in color in another program for the other
<br>> (color-necessary) analysis... but it would be really preferable to
<br>> have these data come from the same source video.
<br>>
<br>> Thanks for your help!
