Accsoon’s CineView Master 4K system has been upgraded to support H.265 encoding at up to 4K 60p. This means improved image quality for the same amount of data sent or recorded. The addition of H.265 makes the product even better.
Additionally, a single CineView Master 4K transmitter can now work with up to 10 receivers or CineView M7 Pro monitors, within a large studio environment. This is an increase from the previous four-device limit and represents a significant improvement for those looking to deploy CineView Master 4K on-set or at events.
Full H.265 Encoding for 4K60

As I have already mentioned, the update introduces full H.265 encoding support, enabling true end-to-end 4K60 video transmission, from input to output. Whether for monitoring, recording, or livestreaming, this optimization ensures more detailed 4K image quality at the same bitrate, with even smoother video performance across all production scenarios. For recordings, users can now choose their own balance between reduced file sizes and increased quality.
Increased Device Connections

Breaking the barriers of connection limits, the new firmware allows the CineView Master 4K to support up to 10 device connections within close range. This means filmmakers can now receive wireless video on over 10 CineView M7 Pro monitors simultaneously across a 1000㎡ studio, making collaborative production easier than ever before. Larger crews can now use the CineView Master 4K to send video to everyone who needs to see the camera image on a set, whether that be gaffers, directors, producers, make-up, wardrobe, script supervisors, or clients.
Advanced Anti-Interference
With in-depth wireless channel optimization, the CineView Master 4K now intelligently avoids interference from WiFi, Bluetooth, and other crowded signals. This guarantees uninterrupted, stable video transmission even in demanding environments such as film sets, live events, and exhibitions.
Enhanced MFi Transmission for iOS
The firmware also refines stability for MFi-certified iPhone and iPad monitoring, delivering more reliable video performance and reinforcing CineView Master 4K as the ideal tool for mobile workflows.
Available now
The CineView Master 4K Version 3.30 firmware update is available now for all existing users via OTA update in the SEE app.
The Accsoon line of products, including the CineView Master 4K, will be showcased at IBC 2025, Booth 12.F57, September 12–15 in Amsterdam.
