* Special Offer Price * NDICam is the original NDI iOS camera built by the world's leading NDI broadcast infrastructure developers - Sienna. Mature and feature rich, uniquely with both Full NDI and NDI HX3 modes. The NDI (Network Device Interface) protocol connects to professional vision mixers and other devices, and delivers a high quality, low latency connection. NDICam is compatible with All TriCasters, VMix, Wirecast and hundreds of other professional IP video systems, software and hardware, which support NDI. - Simple to use - nothing to configure on your iOS device - Switch between front and rear cameras during broadcast - Auto Focus, AF Lock and Tap to Focus - Auto Exposure, AE Lock and Tap to Expose - Illumination light on/off - Audio Mute Control - Manual Naming of NDI Stream source - 4 quality / performance levels to suit your device and network, plus NDI HX Option - Pinch to zoom (where zoom is supported) - Auto-lens mode for multi-lens cameras - On screen live / preview tally plus optional use of camera flash as talent tally (with red gel cover). - Option to prevent iOS device sleep - Select 25FPS or 29.97FPS standard rate. - Choice of Full NDI or NDI HX3 compression modes (HX2 at 2 to 20 mBit, plus HX3 Ultra) - Rotation support for Portrait or Landscape Video Modes. Front and Rear cameras can be selected at the touch of a button and NDICam features a 4 position quality vs frame rate slider to deliver optimum video suited to the quality of your wifi connection and your iPhone's processing performance. Depending on your iOS device, compression mode selected and Wifi network performance NDICam supports up to 1080 full HD resolution. Control of flashlight, touch to focus, focus lock, pinch to zoom and audio enable are also included. You can even use the phone's torch as a Tally Light, by covering it with a red gel. Note: Depending on the performance of your iOS device and your WIFI network, you may not see full frame rates when operating at maximum 1080 resolution with a full HD camera. Using HX3 mode will help if the bottleneck is your WIFI network. Note: NDI is a high bandwidth protocol designed for local area Gigabit networks. In order to see good results you will need a fast, uncontested wifi connection. If you see slow frame rates, try improving the wifi environment, with a better router, less interference, directional antenna or maybe switch to 5GHz if you are on 2.4GHz. . NB HX3 Ultra will use around 50mBits of bandwidth, so it's lower than full NDI, but still quite high. Use one of the lower bandwidth HX3 modes if your network connection is struggling. NDICam is also compatible with wired ethernet connections to iOS devices which can help deliver smooth video compared to a poor quality Wifi network. Good results have been seen with lightning to ethernet adaptors. You can specify an NDI discovery server in the application settings. Note that you will need to restart the app for any changes to take effect. Specifying a discovery server will disable the standard mDNS (Bonjour) advertisement for the NDI Cam source, so your iOS device must be able to reach the discovery server one the network. If you experience problems - delete the Discovery Server entry and restart the app. NB: NDI HX3 Ultra mode requires a recent NDI compatible receiver.

Important Note:
 This app does not currently remove or key out green screens. It is a lighting tool created to help filmmakers properly illuminate their green screens for optimal chroma keying during post-production. Green screen removal is a planned feature for a future update, but it is not available in the current version. Please do not purchase this app expecting keying or background removal functionality at this time. Perfect Green Screen – Light It Right, Every Time Achieve flawless green screen lighting with ease. Perfect Green Screen is an essential tool for filmmakers aiming to master chroma keying by ensuring their green screens are lit to perfection. This app visually guides you through the process, helping you identify and correct uneven lighting using intuitive gray band overlays. Key Features: 1. Adjustable Precision
Choose your desired level of detail by selecting between 2 and 50 gray bands. For most use cases, 9–10 bands provide an ideal starting point.
 2. Visual Feedback
The processed preview displays a gradient of gray bands representing luminance variation. If more than three bands are visible, your lighting likely needs improvement for an optimal key. Think of it like zebras—only smarter and tailored for green screen work.
 3. Exposure & Focus Control
Lock both exposure and focus to ensure consistent results throughout your shoot.
 A Must-Have Tool for Filmmakers
While the app doesn’t perform chroma keying itself, it empowers you to light your green screen like a pro—making post-production faster and cleaner. Simplify your workflow and elevate your results with Perfect Green Screen.
