The addition of the optical version of Thunderbolt to an iMac or Mac Pro could make it possible to connect multiple cameras to a single machine, perhaps through a breakout box containing 3G-SDI allowing for live video mixing of multiple streams.

Wireless production in HD is now a reality

From IP cameras to wireless mesh HD delivery, there were a number of live production options at this year’s Government Video Expo, held last week at the Washington Convention Center.

The new eSATA connectors, which can now be found integrated in to almost every windows laptop that is $500 or higher, offer the same throughput as the internal Serial ATA connectors used in most desktop machines–more than adequate for HD streaming.

In the long run, the consolidation of the transcoding industry may limit choice, especially in the desktop market. Yet the integration of transcoding tools like Adobe’s Media Encoder into editing and post-production workflows means a tighter coupling of transcoding at the time of need for limited-scope projects, and should yield benefits to the event videography market.
