I'm shooting in HQ 1920 x 1080/50i and when I edit audio the sound is very low, around -30db, despite being good when recording. I also don't seem to get stereo.
When I film in XAVC there is no problem with the sound and I get stereo. The only problem here are the files take so long to download so I switched to HQ 1920 x 1080i. I think it must be a problem with the software.
