In this second part of our review, we delve deeper into the different flavors of NDI supported by the Move 4K camera and the camera's ability to perform motion tracking under real-world conditions. Additionally, we discuss how well the camera integrates with other cameras, its resolution quality, and some of its other notable features.
The Move 4K camera supports two types of NDI: HX2 and HX3. HX2 is a lower bandwidth version with higher latency, while HX3 is a compromise between full bandwidth NDI and HX2, offering low latency and better image quality. It is worth noting that HX2 supports up to 4K, while HX3 is currently limited to 1080p in the camera's firmware.
The Move 4K performed well in various motion tracking tests, including single and multiple subjects, even when subjects momentarily moved behind others or were partially off-screen. The camera can easily switch targets using the included remote, allowing for smooth transitions between subjects.
Integration with Other Cameras
We found that the Move 4K could be easily matched with other cameras, such as the SimpleTrack Light, Gen 2, and Sony FX 30. The colors, especially flesh tones, were quite similar between the Move 4K and the Sony, likely due to both using Sony sensors.
While it's difficult to gauge the true resolution quality through an online video, we compared the Move 4K to the SimpleTrack Light and Gen 2 camera. All three cameras were fed over NDI HX2, and the Move 4K showed promising resolution quality.
- Hide Camera Moves: This setting freezes the video output during camera movement, effectively creating a cut between presets and hiding unwanted camera moves in a live stream.
- HTTP Commands: The Move 4K can receive HTTP commands to toggle tracking on and off, which can be useful for switching between manual and auto tracking during an event.
- Built-in Tally Light: A subtle but valuable feature, the built-in tally light indicates when the camera is live in a program (red), in preview (green), or not in either (off).
There are two features we would like to see improved in the camera's firmware:
- Improved auto tracking to allow for user-defined framing of the shot.
- More HTTP support for auto-tracking commands, such as changing subjects, toggling bounding boxes, and separate RTMP/RTSP feeds.
Despite these suggested improvements, the Move 4K camera's capabilities, signal quality, and auto-tracking performance are impressive. We hope you find this overview helpful, and please feel free to ask questions in the comments section.
In conclusion, the PTZOptics Move 4K camera is an impressive piece of equipment that offers a wide range of features and capabilities, making it an excellent choice for live streaming and production environments. Its high-quality image output, motion tracking capabilities, and versatile NDI protocol support make it a strong contender in its market segment.
The Move 4K's ability to handle various real-world situations, such as single and multiple subject tracking, reacquiring target subjects, and integrating with other cameras, demonstrates its potential to be a valuable addition to any production setup. The built-in tally light and HTTP command support for auto-tracking further enhance its usability and efficiency.
However, there is room for improvement in the camera's firmware, particularly concerning auto-tracking framing and expanded HTTP command support. Addressing these concerns in future firmware updates would make the Move 4K even more versatile and user-friendly. With the include 5-year warranty and the team's dedication to improving the camera firmware, this product is a solid choice.
Overall, the PTZ Optics Move 4K camera stands out as a reliable and high-performing option for those looking to upgrade or expand their production equipment. Its robust features, solid performance, and potential for improvement make it a worthy investment for professionals in the streaming and production industry.
