Converting obscure 10 bit YUYV TIFF file?

[silicontrip]

I have received a Tiff file from video capture device. Photoshop and friends only recognise it as a 16 bit grayscale image, yet it is in fact a 10bit YUYV (422) image.

I had to convert it to an uncompressed tiff file (from LZW) and then wrote some custom python to convert it to an 8bit JPEG.

Is there a way to convert this with imagemagick?

Thanks

Probably.

If you link to a sample input, and post your custom python code, you might get a more useful answer.
