    OBS Recording - Window

    Hello !

    Does anyone managed to record Ninja 8 windows with Window Recording feature of OBS ? For me it shows a black screen.
    I'm talking about Window Recording, not Screen Recording.
    Even if i need to create a new AddOn (I already use one). Does anyone knows why OBS doesn't work, and what I can change on AddOne to work with ?

    Thanks !

    We do not have any documentation on what screen/window recording programs do and do not function with NinjaTrader, however, I encourage other users who have experience with the software you're referring to to chime in with any useful information.

      I have the same issue with OBS Studio. Does anyone know of a free screen recording application that can record NT8 windows? Anyone using OBS successfully in NT8 Windows? OBS Studio does work with NT8 if I set it to record the entire screen. But when I try to record just a single window ( a chart for example ) it shows a blank screen. I can move the mouse over the window and OBS shows the mouse moving but leaves a trail everywhere it went. I tried 2 different computers, one Win7 and other Win10(built using Intel integrated graphics) ... same problem. I checked OBS logs, nothing suspicious. Checked OBS forum. Found some others with similar problems recording games but nothing that led to resolution. This problem falls between the cracks of NT and OBS.

        confirm OBS doesn't work with NT8 Windows for me (per #Brillo works for display, just not Window - suggestion workaround - FullScreen the NT window you want to record & record the Display?). Doesn't work with MS Edge either, for example. My guess would be it is to do with the technology the windows use and OBS not being compatible - NT8 employed some new technology/format in 8 iirc (wpf or wpm or some other such acronym) but I'm not fluent in Conehead, just a simple soul.

        I believe it is simply a case that NT uses a Windows window technology that OBS isn't compatible with. Would have thought NT could determine, as they know whether I'm rambling or some credence to what I suggest i.e. they know that they use custom windows and that there's a fair likelihood that is the cause of OBS not working with them

        Alternatives - Techsmith's Jing but end of Support. Bandicam (limited clip duration with free version, iirc).

          For anyone interested:
          The problem is with the technology behind Ninja, WPF.
          WPF uses some kind of trick rendering behind it, but it can be disabled.
          So I managed to get my AddOn woking with OBS and WindowCapture, but not default Ninja windows.
          To get that you need to set to False the property AllowsTransparency of AddOnFramework class.
