network rendering and m2t files as source media

dreamlx wrote on 5/1/2005, 9:14 AM

As far as I have understood, network rendering cannot be used to render to mpeg 2 file as destination due to licensing restrictions. I am just wondering if m2t files can be used as source media in network rendering session ?

Hmmm... even if you could (not sure about that)... you would likely have a quality penalty during the stitching phase - as it would re-compress the video again.

Now... the way I've been thinking about this (all theoretical... as I don't yet have a Z1U)... is that you would work with the intermediate codec (now built in to V6) and network render with that. That codec I believe has very low compression loss in comparison to using the m2t direct (I'm no expert here... so please anyone who really knows - chime in)

In an idle discussion (IOW: not very detailed) with a Sony developer at the NAB party I was informed there is an issue where you only seem to be able to network render using the intermediate codec if all the source files are physically on a network drive. Sounds a bit strange I know... and I have not done any "testing" to see what this means.

Well in fact I wanted to use network rendering in (well don't remember know the name of the mode) the mode where one networked machine does the rendering of the whole project. So there would be no stitching phase. The reason for doing this is to encode to multiple formats on more pc's. Would be nice if someone having already setup network rendering could test this. Concerning intermediary codecs... for my workflow I prefer rendering my hdv material to dv format, using these files to edit and afterwards replacing them with the original m2t files. This avoids one more recompression.

Well it seems nobody has done this till now... It would be nice if someone currently having setup network rendering could try it out or if Sony could answer this one, as I want to be sure it is working before investing in additional machines.
