If you downgrade from this version to an older one, there may be an encoding failure problem caused by the incompatibility of the configuration files. You can solve this problem by restoring the factory settings. When there are no restrictions on the size and duration of the recorded files, you need to ensure that there is enough disk space. Alternatively, you can select the recording strategy of stopping recording when the space is insufficient. When deleting oldest recordings is enabled, the system will automatically remove the oldest files in the specified directories (HDMI/SDI/MIX) if the storage becomes full. Due to the influence of the Internet on the NDI bridge, when the network is congested, the audio and video might be out of sync. When the network returns to normal, it will automatically recover . After restarting the device or inserting a storage device, it will be slow to open the recorded files on the storage device for the first time. After upgrading to version 1.21, you need to perform a refresh (Shift+F5 or Ctrl+F5) to enable API authentication; otherwise, login issues may occur.
