    It's extremely common for a company to use a shared code-base across multiple products. That way any changes to fundamental bits of code are uniformly implemented across the product range.

    Encoding NDI|HX is only done using dedicated hardware. So NDI Analysis is incorrect in the assertion that the stream created by vMix (or OBS) is NDI|HX.

    So the problem must be something else. It's...
  3. Premiere Pro Stalls on launch - reports loading NDI

    This afternoon I'm editing some video on my vMix system I notice that when I launch Premiere Pro 2019 it stalls for several minutes displaying a screen that reports "Loading Newtek_NDI_transmit.prm."...

    I noted that the NDI|HX driver was not installed with NDI Tools 3.8.

    Failure of the installer seems a common theme.

    There's a whole lot of overthinking going on about switches with buffering. A SWITCH typically cannot substantively delay an NDI signal.

    A very poorly configured ROUTER may introduce delay as a...

    Details matter. The Atom version cannot handle 1080p60. Nor does the Celeron N3450.

    In the case of the N3450, it's not the CPU that's overloaded. It's the mated GPU. It can only get to about 48...

    I can say from experience a Celeron N3450 (Passmark score =1823) will not play 1080p60 reliably. It drops several frames/sec. It does play 1080p30 fine.

    The Z8350 you cite has Passmark = 1269...so...

    Given the history of legal issues with Newtek and the GPL, NDI is not included in FFMPEG. That makes NDI on Linux more challenging. That would likely impact NDI on ARM SBCs like RPi4.

    Sienna does...

  11. NDI Tools 3.8 installer does not correctly install HX driver.

    I have several brand new SFF Windows 10 PCs. They are to feed some projectors from an NDI or NDI|HX source. They have NDI Tools 3.8 installed.

    Using Studio Monitor, selecting an NDI source...

    Be aware that Connect doesn't deal with many webcams well. You need to try it to see if it will actually deliver your desired resolution & frame rate.

    I've opened a support ticket about the manner in which "Scan Convertor" and "Connect" handle webcams. It's basically faulty. I've tested with a number of Logitech webcams from the old C920 to the...

    Note that some time after this thread was underway, vMix implemented MMF access to Brio. That uses NV12 encoding (4:2:0 8 but) supporting reliable 4k30 operation without latency.

    Revisiting this old issue in the light of NDI Tools v3.8.

    Dr Cross,

    Thanks for the reply. That's very interesting. I'll certainly relay this to Martin Sinclair at vMix. It may point to some more fundamental differences in how they implement PTZ remote...

    NDI SDK and PTZ control

    It's been noted that the PTZ controls in Studio Monitor are vastly better than what's possible using third party apps like vMix.

    When I approached the vMix user community to inquire about this, I...

    Tracking this a little further, it appears that any time Scan Convertor is unhappy it's failure mode is to select 640x480p30 4:3.

    It cannot access a Logitech Brio or Rally at 4k30. It always...
  20. NDI Scan Convertor v3.7 - ignoring webcam settings

    Hi All,

    I just updated two PCs to NTI Tools v3.7. Wanted to see if the lesser of two could be used to access a Logitech C922 webcam, making it available as an NDI source.

    When I do this, the...

    Lemme try to understand this. You want to capture the laptop output to the phone, so the phone can do the live stream. Is that right?

    Maybe, but it's not NDI-based. There are a few Android apps...

    This morning I loaded NDI Tools v3.6 on a laptop. The resulting "Virtual Camera" does work in those WebRTC apps, although it is frail. After using it once successfully, it becomes unresponsive. I...

    Hi All,

    I was helping someone work out a problem in a production workflow. Along the way I have discovered that NDI Virtual Camera v3.6 does play well with some popular applications:
