> Agree …. it would be good to move to something more efficient and open … the idea of OpenEXR is good but it seems the digital footprint is too large for many pipelines … DNxHD is efficient and though owned by a single company is at least targeted at the professional community … the other codec that might rise to the occasion is SRFile (essentially MPEG 4 SStP) … and though controlled by Sony it offers the double benefit of being tried and tested (virtually every TV show and movie has over the last six years touched an HDCAM-SR tape at some time in it's life cycle) and of being visually lossless and robust … with the new Sony 'open kimono' approach and the publication of the SR SDK and companies like Blackmagic, Colorfront and Filmlight already incorporating the file format into their software, we might have a file format that can act as as acquisition codec plus workflow codec.
> At our Open House last week, we successfully demonstrated encoding SRFile using an alpha version of BMD's DaVinci Resolve …. the image quality is impressive, the footprint very acceptable … we've transcoded Alexa, EPIC and F3 footage to SRFile in three different flavors and projected at 2K, people are hard pressed to distinguish between the three different compression levels.
> If the industry accepts the idea that SRFile encoded files are a viable alternative in file-based workflows, we might just have a defacto industry standard that we can trust as much as we could the SR tape based format.
> Ironic, that a tsunami in northern Japan has catalyzed one of the world's largest tape vendors to move rapidly into the open world of file-based workflow.
