Re: [Avid-L2] Re: DNXiO FAQ

 

As far as I know the past and current BMD I/O cards still can't be used to output to tape.  They roll the timeline 1 frame late which results in a frame of black at the top of every insert edit.  I can't imagine the DNXiO doing this.  So will this mean the older cards are finally going to get this fixed.

The lack of universal mastering is a big shortcoming but so is the inability to make a proper insert edit to tape.  Does anybody know if this has been fixed with the current and past BMD cards?

John is correct, I was referring to Symphony Universal, or frame rate conversion. We use this constantly and it is only available with the Nitrsi DX / Symphony combo. It will be missed. The rest of the conversions the box does are available on the 1K cheaper Blackmagic version of the box. 

So, I am still not excited by this. Might as well go with AJA's 4K card and have the added reliability.

I haven't gone through all the specs but perhaps it's the lack of Universal Mastering and not standards conversions that is missing.  Of late I've had a need for the universal mastering and as more of my series work switches to 23.976 offline and online with a 59.94 tape delivery I see more of it in my future.  So with this box is universal mastering gone like it has been with the other 3rd party I/O.  Is that feature impossible without the NitrisDX.

The mention of audio punch in seems to be something that use to be impossible with some or all 3rd party I/O solutions.  I'm virtually always on Avid hardware so I don't know it the audio punch in feature was ever enabled on 3rd party hardware.  Anybody know what that status is?

I say:

The hardware unit has two built-in power supplies.  There would be no point in providing two power cords unless they connect to two separate built-in PS's:

Power supply

Two built-in international AC power supplies with IEC C14 inlet (120–240V, 50–60 Hz)


Mr. Curren:

> And you can save $500 by trading in your Nitris DX which had realtime standards conversion (goodbye to that feature), Ancillary data support (probably gone also), and the processing that Nitris DX took off the CPU / GPU hands.

I point out:

Artist has realtime hardware up/down/cross conversion:

Down conversion

Built-in, high-quality hardware down conversion—Ultra HD to 1080 HD, or HD to SD on SDI B and SD on Component and NTSC/PAL; switch analog video to Component and choose HD or SD output; selectable between letterbox, anamorphic 16:9, and center cut 4:3 styles

Up conversion

Built-in, high-quality hardware up conversion—SD to 720 HD or 1080 HD on playback; selectable between 4:3 pillarbox, 14:9 pillarbox, and 16:9 zoom; HD outputs via HD-SDI, HDMI, and component analog

Cross conversion

Built-in, high-quality hardware cross conversion—720p to 1080i and 1080i to 720p on playback

Other hardware conversion

Colorspace conversion


Since Artist provides 2K, 4K, and UHD resolutions, it wins over Nitris DX which cannot handle these resolutions at all.  Artist's biggest limitation at the moment seems to be its lack of analog audio inputs and outputs as there is no way to monitor more than 4 analog channels of audio without additional external hardware (HDMI & SDI can accommodate up to 16 channels of imbedded audio in and out).
