bmpc 4k audio recording

i am testing the camera recording prores 422 hd audio xlr +48v-mic background music is playing i stop after 10 minutes when i see the video the audio is not cover all the video what i miss in the setup

Were you recording in high frame rate mode? If so, the audio and video will not be the same length.

i am not sure fps shows 60/29.97

it looks i was recording high frame rate when i change and record to 29.97 video and audio same length
thanks

Make sure you are not using HFR or the audio sync may still be off a bit.
