One of my functions at church has been to videotape the Senior Minister at our Men's Thursday Morning Bible Study. This lasts almost an hour. I setup my Sony HDR-HC9 with a Rode Stereo Video Mic., set the camera from audio AGC to manual gain, and the manual gain level. The camera also gets plugged into a small external monitor. I plug my headphones either directly into the camera or into the monitor, so if there is a sound problem, I know about it. I also have the camera plugged directly into a PC laptop via FireWire for direct capture using Vegas MovieStudio 9.
This past Thursday I recorded the 54 minute event, and generated a file checksum for the video file (1080i60 m2t), which allows me to verify file integrity as it gets copied around. I then copy the two files to a USB hard drive (WD Passport 160 GB). When I get home the two files get transferred from the USB hard drive to my desktop computer for verification, edit, render, and DVD creation.
My problem is this. When I load the video file into Vegas on my desktop, Vegas does a scan of the file to build the sound waveform view, or I assume that's what it's doing. It skips over the sound from the ~2:34:07 (minutes:sec:frame) to ~26:33:14. Indeed, I can watch the scan skip from 3% to 50% in the blink of an eye. When I look at the sound track in Vegas, the sound flatlines from between the aforementioned times and when I play it to start figuring out where my chapter marks should go from the sound, the sound goes dead quiet for that ~24 minutes.
I can play the file just fine in VLC and the sound is all there!
Does anybody have any idea what's up with this?
I've done this half a dozen times so it's 100% repeatable - on my machine at least.
Thanks in advance.
