Anyone else (sometimes) losing audio when previewing large avchd files?
Hi… I have some big Sony AVC files which sometimes do not play audio when I am previewing. If I redrop the file onto the timeline somewhere else it plays. If I delete the peak .sf files the peaks rebuild but still no playing.
Is it just me? I’m sure I can live with it, but it is a little inconvenient…
Vegas 11, W7, etc.

Where do these files come from? Sometimes Vegas has difficulty with files from different camera manufacturers who don’t strictly follow the AVC specification.

Hi John, thanks for responding! Basically it’s 4 or 5 Sony TG5V AVC files “glued” together as follows
c:> copy /B 00000.mts+00001.mts+00002.mts+00003.mts bigfile.mts
As i said, it’s not a big problem but just wondering 🙂
Hey so one more question for you… just curious – on a pro-grade Sony camera, I assume the issue of big files rolling over is resolved? Do they save as one big NTFS file? I guess the problem is the low grade cameras can’t quite keep up with themselves when writing the video to disk/memory…
thanks!

Pro and consumer cameras such as Sony’s either use Picture Motion Browser or XDCAM Xplorer to seamlessly stitch the files together. The media files can be dropped directly to the timeline (thus bypassing the tool) but they typically end up missing 3 frames at the beginning or end of each file.
If your camera came with similar software, use it. It has been provided for a reason.
My system specs: Intel i7 970, 12GB RAM, ASUS P6T, Vegas Pro 10e (x32/x64), Windows 7 x64 Ultimate, Vegas Production Assistant 1.0, VASST Ultimate S Pro 4.1, Neat Video Pro 2.6

I would only use that method if the correct way to import didn’t work for some reason. It may be the source of your problem. The correct way to import these files is to use the Device Explorer in Vegas and let Vegas stitch them together properly (View | Device Explorer (Ctrl+Alt+7)).

No, it will never be resolved. NTFS is not licensed by Microsoft and so FAT32 is all any camera will ever have to work with until something else becomes the standard (perhaps iOS?). 😉
