Cinegy Air 26.2 Release Candidate

Important Known Issues in Cinegy Air

  • The current limitation is that user data in the output stream is not supported by the AMD GPU manufacturer.

  • An issue occurs with Intel GPU encoding when using HEVC with a B-frames GOP structure.

  • Cinegy Air control legacy APIs will no longer start automatically and will need to be manually started.

  • AAC audio in the Cinegy Air control application preview can be distorted in some cases (defect 13432).

  • Frame numbering issue for IBBBP/IBBBBP output with AAC-LC audio with some specific video codecs and bitrate (defect 15917, ticket BVA-906-12970).

  • Audio packet size decreases during audio silence on IP output with AAC-LC audio (defect 15950, ticket ENI-672-26743).

  • Cinegy File Browser is missing in Cinegy Studio (defect 15091).

  • Colors in semi-transparent areas within the media file used in the Cinegy Title template are displayed incorrectly if the color specified in the "Source Matted With Color" parameter is not black. The issue occurs for the Straight and Premultiplied rendering modes when previewing secondary events (Cinegy CG preview in the "Load Template" window, Clip viewer preview) and Sequences (Cinegy Title template as a main item) output. We recommend generating media files with Premultiplied alpha using the black background and not changing the black color in the "Source Matted With Color" parameter in the Cinegy Title template.

  • Changes to the voiceover stream settings (e.g., SRT to RTP) require restarting Cinegy CG for the new settings to take effect on the Cinegy Playout engine.

Third-Party Known Issues

  • Customers are advised to consider installing the latest security driver update from NVIDIA. For details refer to the NVIDIA Security Bulletin from October 2024 https://nvidia.custhelp.com/app/answers/detail/a_id/5586

  • If you are using GPU-accelerated NVIDIA features, please ensure that your settings match the capabilities of your specific board. Due to an NVIDIA hardware restriction, interlaced H.264 encoding is only supported on Pascal and earlier boards, and also on Blackwell GPUs.

  • Blackmagic Design DeckLink video cards occasionally play video without sound or with distorted sound on the output. This issue may be related to a PCI bus problem when working with the new generation of processors.

    The following recommendations can be tried to address the Blackmagic Design DeckLink stability issue, verifying the audio problem occurrence after each step:

    1. Install the latest Blackmagic Design DeckLink drivers.

    2. Update the BIOS.

    3. Enable the "Above 4G Decode" setting in the BIOS.

    4. Enable the "Resizable BAR" setting in the BIOS.

    If the issue is resolved after completing any step, the remaining steps can be skipped.

    If the audio issue persists, please contact Blackmagic Design for further recommendations.
