I thought this option was added a few updates ago, but I'm not seeing it. I updated to the latest version today and still do not see it. There is a continuous + alerts option instead but that's not what I want for dual-stream recording. I want substream until a camera triggers, then switch to main stream. Then I only want alert notifications to my phone if something I'm interested in is identified. And keep recording main stream until the camera is no longer being triggered. So what happened to this option? I can get around this by having a cloned camera only record the substream continuous, but it not as elegant.
The feature has been renamed as explained in the help file and release notes.
Continuous + alerts. When used with a dual-streaming camera along with direct-to-
disc, the result is a BVR file which will contain the sub-stream continuously
recorded, but the main-stream only recorded when the camera is in a triggered state
(or alerted state if you are using alert confirmation via AI). During main-stream
playback, the sub-stream will be upsampled whenever the main-stream is not
available. This dual-stream hybrid may be exported only when re-encoding is
selected, although you may still export the main-stream in segments when not re-
encoding. When not using dual-streams or direct-to-disc, a frame will be captured
continuously at 1fps unless the camera is triggered.
