Beware the fibre contamination!

These are two pictures taken down my hand-held fibre microscope - you can see the core and buffer of two examples of fibres that were spliced maybe three months ago in a new building. I suspect builder/decorator dust contamination and even though they have had their cover-pieces on they aren't air-tight and so we're now [...]

'Beyond HD Masters 2013'- cable interfaces and framerates.

After 'Beyond HD Masters 2013' – 4K TV colourimetry

Nano Flash Workflow Guide

Nano Flash is now a very popular tapeless recording addition for any camera with an HD-SDI out. The reason for it becoming so popular is that it can record a number of different formats which broadcasters approve of (basically anything that can record a 50Mbit + data stream). It’s a great way for production companies to get [...]

The party is truly over for Mac OS and malware

For a very long time Mac users have reassured themselves that the nasty stuff will always happen to those uncreative and unimaginative Windows users.

Setting a 12-core "Westmere" Mac to 32bit Mode

When Mac OS Snow Leopard is installed onto a 12-core Mac, it defaults to 64bit mode. Unfortunately, all Avid applications that run on Mac require it to be running in 32bit mode. They may install but that doesn't mean to say they'll behave. For example, Media Composer will pretend everything is hunky-dory, but will stubbornly refuse to see any Avid hardware, including the Nitris DX and the dongle.
