Atomos Ninja or any external recorder?

    It's great to be able to talk to an informed person like yourself. Too much info out there, and half the time, I suspect pp just cut and paste stuff, and pass it off as their opinion.

    anyway, here is something I found that might help you look at red channel:

    Cheers mate

  • @Kazuo

    Regarding red channel .. I am not much of pixel peeper .. I will try and shoot some red for you early next week .. perhaps a rotating colour chart .. message me and remind tuesday if I forget .. I don't have to leave the house until next thursday - family duties and housework today.

    Have you any examples where others have shown the red channel issues?

    The hacks are entirely irrelevant to recording via externally via HDMI .. when I record externally I use something that is safe and spans reliably (cluster of flomotion).

    I am a convicted BMD fanboy .. I love my hyperdecks (studio and shuttle).

  • @kavadni

    Hey dude, I know you live in PAL land, so do I :) so I can disregard the NTSC guys now heheh. I read that you have invested in the Hyperdecks as well.

    1. Having recorded with the GH2, how are the results? How's the red channel? Read reports about it still being jaggy.

    2. Can external recorders work with a hacked setting on GH2? Or do i have to reset the camera back to default v1.1 firmware?

    I figured I would rather get the Hyperdeck rather than Ninja because of BM's support network. Besides, BMC is really an evolved Hyperdeck, so getting it is like getting half the BMC!

    Cheers

  • IMHO .. if your in PAL land (as I am) and require 25P it is worth doing.

    NTSC persons seem to have issues (pulldown/cadence) that I have not encountered

    Yes it's PsF .. so deinterlace it, or whatever dependent upon your NLE.

    As many have noted the GH2 24P codec eats the 25P/HBR codec. This is irrelevent when using an external recorder.

    You can choose your codec (dependent upon your external recorder) .. I use DNxHD

  • Yeah, this has been beat to death. Another reason to shy away from external recording on the GH2 is the mini HDMI port is not very robust. Presumably external recording would be for some high end studio work -- that HDMI port is about the last thing I want to trust on a GH2 unless you've got a killer cage/clamp set up -- and even then, risky.

  • Been there, looked into it, asked here and it's not worth doing. Just mt 0.02

  • There is very little to gain from externally recording today afaik. While it seems possible to record without interlacing artefacts - at least in PAL land and cam set to HBR (its still tagging the HDMI output as 1080i while delivering PsF... afaik ) - and its no compression applied beside the well known downsampling to 4:2:0 - there is still very little reason to spend the money and take the hassle. The difference between high end settings like sedna or flow motion and external uncompressed recording might help with chromakeying anyhow. If you plan to record events with other shooters locked to 25 fps or want to be more flexible with shutter in 50 hz pulsing light you might also thing about external recording. Just don't expect any miracles.

  • There was a whole project dedicated to analyzing the HDMI out in this forum. The results were that there was no advantage in using an external recorder. i am sure you will find the thread here in the forum. :)

  • @fatpig

    When you say messed up interlaced, how bad is it? The Ninja website describes the output as "beautiful" Surely one man's meat is another man's poison, or is there more objectivity than meets the eye? Is the footage going to be usable?

  • HDMI output on GH2 is compressed. And messed up interlaced. Your best option is driftwoods high bitrate patches like quantum 9b.

  • @kazuo AFAIK the GH2 has no way of knowing if the HDMI signal out is being recorded or not. I don't believe there could be a built-in limitation like you describe.

  • @subco

    I read that hdmi outfeed for monitoring is clean, but somehow recording is not (am i making sense?) Because of this, someone actually wrote to Panasonic, and got a terse reply saying, and I paraphrase, "HDMI has always been there for monitoring and not recording purposes."

    All this conflicting stuff that i have read is really driving me nuts. But thanks all the same for the info
