Hi, I was shooting a 1.5hour seminar with the Panasonic GH4 in 1080p 50mbps mode. The GH4 created 8 4.28GB files as I think it is something to do with the file system. I recorded the audio from lav microphones by plugging in my iphone with XLR>ipohone adaptor and recording 44.1 khz apple lossless file using the Rode App. Sound quality was very adequate. I had a Sennheiser MKE-400 mic on the GH4 to record the speakers voices that were broadcast over several speakers. This audio is not bad but has a lot of room noise. I selected the 8 clips and the audio clip and hit synchronize clips. I tried this several times and the audio does not sync up most of the time or is only synced in the first clip. I have tried creating a compound clip from the 8 files so that I can sync the audio but it doesnt work. I am hoping I dont have manually sync the audio. Anyone know why it doesn't work. I even tried syncing individual clips. No luck. Thanks.
