Adjusting trigger output from OptiHub
Posted: Thu Feb 25, 2016 7:47 am
Hello,
I am using Motive 1.7.5 on a 64bit system. I have 3 Flex13 cameras and the OptiHub 2. I'll be upgrading to Motive 1.9.0. soon.
I would like my OptiHub to send an output trigger each time the cameras capture an image, but only while recording a take. In the Synchronisation pane I use a "Custom Synchronisation", I set the Sync Mode to "OptiSync", and the Source to "Internal". Since I want triggers only while recording, and each time the cameras expose, my only option is to choose "Recording Pulse" in the External Sync Output. However, the device I am syncing to (which receives the triggers from the OptiHub) will only recognise a trigger if it has a duration of longer than a certain time (I am not yet sure what this duration is exactly, but I expect it to be around 10 - 15 ms), but the triggers from the OptiHub are as long as the camera exposure time (usually around 4 - 8 ms, I think), which is too short. So, my question is, is it possible to specify the duration of the output trigger from the OptiHub?
Obviously I realise that one should be careful in specifying the length of the output trigger to ensure it is not longer than the time between subsequent camera exposures, or the triggers will overlap each other.
Many thanks.
