I just wanted to let you know that we've released an important upgrade to the SheerVideo Pro Preview. You can download the free preview from


The new version, 0.9.3, adds the following features:

'yuvs' support

Although hardware and software vendors are converging on '2vuy' as the standard for Y'CbCr 4:2:2 video, 'yuvs' is still very popular. The new release of SheerVideo adds direct support for 'yuvs'. This means that SheerVideo can now compress 'yuvs' video faster, since QuickTime no longer has to convert from 'yuvs' to '2vuy'.

Note that SheerVideo also supports 'yuv2' (also known as 'yuvu'), as well as RGB.

digitizer support

SheerVideo now works seamlessly with video capture cards. The previous version had a problem communicating with the sequence grabber.

extended preview period

This release of SheerVideo expires on 28 February 2003, giving you more time to try it out.

public component resources

The SheerVideo QuickTime components now broadcast their capabilities with "public resources". This speeds up codec selection, since applications no longer have to open the codec up to check what pixel formats it handles.

tip for the month

In the field, you can edit and play back SD video in real time on a PowerBook using SheerVideo, even in RGB format, without RAID disks. For playback, just make sure that you don't have any other applications running, and that your disk space isn't too fragmented. For editing, also make sure that each video stream is on a different disk. One stream can be on the internal hard disk; the others have to be on external FireWire drives.

feedback, please!

Is SheerVideo working out for you? Is it fast enough? Does it compress enough? Do you want us to add any other features? Do you need support for any other platforms? Please let us know!

I hope this update is helpful. This bulletin is also available in German and French.
