Hi,
I had a similar problem recently with avi files made by matlab and FIJI that I wanted to play in powerpoint. Provided you have the correct codecs for the avi, I found that changing the file extension from .avi to .mpg made it play properly in powerpoint regardless of the codec used to encode it.

Hope this helps,
Justin.

Hi Jason,

I'm not sure if you're using Volocity or ImageSuite to control your UltraVIEW, but assuming it's Volocity here's some general advice that I hope might be useful!

- On Windows, I would prefer WMV over AVI - WMV is a newer format with better compression and support. It also has much less to configure (and therefore much less to go wrong).

- On Mac OS X, I would prefer Quicktime with H.264 compression. This is a modern, high-quality codec.

If you're using Powerpoint, then the situation is somewhat harder:

- If you're using Volocity on Windows and PowerPoint for Windows then export as WMV. This should work out of the box.

- If you're using Volocity on Mac OS X and PowerPoint for Mac OS X then export as Quicktime with H.264 compression. This should also work.

- If you're using Volocity on Windows and PowerPoint for Mac OS X then export as WMV and install "Flip4Mac" on Mac OS X. This is free and will allow Quicktime to play WMV files.

- If you're using Volocity on Mac OS X and PowerPoint for Windows then it's a bit more tricky - PowerPoint for Windows is (frustratingly) not compatible with Quicktime. The best solution I have found is to convert the movie to WMV on Windows, there are lots of free applications for this, or you can use this rather nifty website (no commercial interest):

Cheers,

Has anyone using the MacOSX Snow Leopard (10.6.x) had any issues with
playing uncompressed .avi files in QuickTime (either QuickTimeX Player or
QuickTime 7.6.6 for 10.6.x)?

My movies play fine on a machine with OSX 10.5.8 using QT 7.7, but they
won¹t play on a newer machine using OSX 10.6.8 and QT 7.6.6 (you can¹t
install QT 7.7 with OSX 10.6.8); addition of various codecs and readers
(DivX, Xvid, Flip4Mac, Perian, 3ivx) does not help. Specifically, these are
.avi movies processed in UltraView or MatLab that worked fine on my previous
Apple machine but will not run on my newer machine running OSX 10.6.8.

The movies play in VLC regardless of the platform, but VLC movies can¹t be
embedded into PowerPoint 2008 or 2011 (as far as I know) and must be played
externally; if someone knows how to tell PowerPoint to use VLC instead of
QT, then I would be most interested to know.

Any insight into potential problems experienced by others would be most
helpful for troubleshooting this issue.

Thanks,

Jason Ford
