  HDV uncompressed from a Z1

  Posted by Robin on September 28, 2005 at 10:35 pm

  Has anyone here actually done this?

  I want to have a go and wondered what people’s set-ups are or potential set-ups for capturing HDV bypassing the tape.

  I’m guessing you’ll need a multibridge (or similar) a G5 with FCP and a super-fast Raid array.

  But just how fast? and how much space will it take up compared with HDV?

  hmmm… any ideas?

  I hoping you’re talking about live capture here. Otherwise if you’re capturing off the Z1 tape(read mpeg2 compressed here), then the advantages of using BMD kit would only be similar to using another intermediate codec i.e. cineform aspect, which is reportedly meant to be more robust when it comes to putting in effects, colour correction etc on the ‘HDV’ footage.

  You hear various stories about live capture of the Z1 i.e. the analog signal may or may not digitise to 4:2:2, it may or may not be 8 or 10 bit, it doesn

  Hello

  I have done this in 50i with aja HD SDI to component converter (because I wannted the analog signal cables to bel less than 15cm, juts to make sure that I would not introduce any analog noise from surroundings / and the sheer fact that I do not have a multibridge)

  I captured 10bit and I can tell you right up that you will run into trouble with just 4 disk raid0 – adding one disk made it go away (not till the end of drive but at least 1.5h (300GB drives) )

  Funny thing is that it is easyer to editin uncompressed than HDV on the coputer (in 10bit timline there are no RTfx /and using 8 bit timline with 10bit footage dosen’t help as well)

  So in conclusion, can be done – storage is bit tricky (unless you want to bring an Xraid to the set) no HDCAM but way better than mpeg2 stream
