Too busy to blog!

I'm snowed under; long days helping a big facility to move premises. I've tried to take half term off too spend time with Sarah and James (the only boy left at home since his brothers went to Uni last month) but have wound up working two days so far this week - ho hum.

So; here are just a few technical things I had to get off my chest.
  • If you use a Blackmagic Ultrastudio Express (I do - it's a a great way of playing out HD/SDi for demo'ing equipment, calibrating monitors and displaying training material) then be aware that the current version of the app/driver (v. 9.8 currently) is very unstable on OS-X 10.9 Mavericks - use the previous version 9.7.8 instead - all here.
  • Do you ever need to demo/test DolbyE encoded material - this is the clip I use (from my pals at National Geographic)
  • Do you ever need to do audio shuffling within an HD/SDi signal - shuffle, adjust levels, correct phase reversals, delay (up to 2,400mS), maybe apply dynamics? The most effective way I've ever found of doing this is with an AJA HD10AM, a Yamaha 0196V and the MY8AE option card; £2.5k for full control of two audio groups within an SDi stream; You couldn't do that with anything from Bel, Snell & Wilcox, TC Electronic or any other manufacturer of audio processors.
  • Hard drives - "MTBF= 30k hrs"; inter-quartile range is where >50% of HD fails occur. A few last 100k hrs, some only 2hrs as I discovered when the replacement cloned hard drive in my media computer failed after a couple of hours of use. Thankfully I'd cloned it twice! Don't trust spinning hard drives. A motto for our age should be "Friends don't let friends use RAID5"!
That's it, Christmas can't come soon enough!
