MOX: Do we need an open source codec?

Over on IndieGoGo there’s a project for MOX – an open source mezzanine codec for (mostly) postproduction workflows and archiving. The obvious advantage over existing codecs like ProRes, DNxHD and Cineform is that MOX will be open source, so there is significantly reduce risk that the codec might go away in the future, or stop being supported.

Technically the project looks reasonable and feasible. There is a small, but significant, group of people who worry that support for the current codecs may go away in the future. There’s no real evidence for this, other than that Apple has deprecated old, inefficient and obsolete codecs by not bringing them forward to AVFoundation.

I have more concerns for the long term with an open source project. History shows that many projects start strong, but ultimately it comes down to a small group of people (or one in MOX’s case) doing all the work, and inevitably life’s circumstances intervene.

MOX is not a bad idea. I just doubt that it will gain and sustain the momentum it would need.

Demystifying Apple’s ProRes Codec

In this free webinar I examine Apple’s ProRes codec inside and out. Content includes:

Apple’s ProRes family is becoming one of the most common formats in production and postproduction, but how much do you really know about this code? Which version is best for your needs?

  • Introducing the ProRes family
  • RCBA vs YUV – what does it mean?
  • Lossless vs Visually Lossless
  • Using ProRes: a codec by codec guide.

Evolving Thinking: 4K and Lumberjack

I frequently find myself evolving my position on technology as new information comes to light. As my email sig line used to say “Above all, I reserve the right to be wrong”. As new information comes to light, or reaching a certain point in thinking allows another perspective to open up, my positions frequently evolve.

One example would be the use of 4K, another is the development of Lumberjack System.

QuickTime is deprecated? What does that mean in practice?

There as been some discussion – and a little panic – as the news has leaked out from developers that “QuickTime is deprecated”. What does that mean and what affect will it have on video professionals? When an OS API (Application Programming Interface) is deprecated, developers are warned to not write any new code using that API, because at some future (usually unspecified) time, the API will go away and the code won’t run.

Mavericks bonus: OpenCL on both my GPUs!

Buried in John Siracusa’s excellent review of OS X Mavericks is this little gem:

Modern Macs with integrated GPUs get some nice improvements in Mavericks. Any Mac with Intel’s HD4000 graphics or better can now run OpenCL on the integrated GPU in addition to the CPU and any discrete GPU.

It’s that little bold bit that makes it special! With OpenCL increasingly taking up the load of general computer processes previously forced on the CPU, the more we can take advantage of the GPU power already installed.

Thoughts on 4K for production and distribution.

I have conflicting thoughts about 4K for production and distribution. At one level I’m convinced it’s being pushed on us by equipment manufacturers when there is no real demand: at another I know from experience that there are some non-obvious advantages to 4K. But one thing is clear: the push to 4K is not about a push to improved quality.

Romney’s campaign used Final Cut Pro X, with help from Crumplepop

So curiosity took me through Ars Technica’s look at the Romney campaign’s technology – Romney campaign got its IT from Best Buy, Staples, and friends– and got down to the heading Picking a few things up at the Apple Store and see that Apple picked up a decent customer in the campaign.
