Sony Vegas Capture problems issues
hi,
I have a Sony HVR A1E and use Sony Vegas 9.0c to edit. When I play the tape directly to a tv (AV) it looks great! However when I capture, the results can be mixed. Usually the first clips are good but the later and larger the clip the chances of parts getting dropped or the sound going [or hunting] are greater.When you monitor the progress of a capture on the camcorder lcd it also looks great. But the preview on Vegas can stall or flash green momentarily. It looks as though the camcorder streams data at the rate it records it but my laptop can’t always keep up. It has 4Gb memory and runs Windows 7.
Does this analysis sound correct? What can be done?
As this is capture there is no need for a race. All I want is data on the camcorder to be copied to a hard disk. I have been thinking about adding a capture card to another pc but will that help? if the card only adds connectivity the problem of matching the data rates will remain.
thanks

It could be that your laptop is underpowered to capture HDV although it’s the same bit-rate as regular DV. Most modern PC’s should handle it. I would definitely try on a faster computer if you have one. Also try turning off the video preview. This will save more CPU cycles for the capture. Is the capture reporting that it is dropping frames? If it is, make sure that your hard drive is defragged and has plenty of space. Your computer may be looking for places to store the data which is not a good thing. Always keep your capture drive defraggmented.

I have always been told that a capture should be done on a second hard drive. That helps avoid the situation where program/OS access to the system drive competes with the capture process for disk resources. A capture that works well at first, but deteriorates sounds to me like that sort of contention. I suspect your laptop has only one drive.

Hi,
thanks for the suggestions but they are both variations of clearing the path for the capture program to run. With todays bloatware, anti-virus, index scan’s etc it is harder to achieve than it should be.
How do tge pro’s go from tape to disk? -
The pros do exactly what John and Bob suggested.
In addition, make sure ALL non-essential services are disabled during capture.
This means no surfing the net while you’re capturing 🙂 -
Hi,
no surfing? 🙁I had a go at editing some of the clips and to my surprise the results when rendered are much better than I was expecting. I’m still not sure whether I’ve dropped some frames but maybe preview on Vegas is partly to blame for a perceived acquisition problem.
I’ve also started thinking about recording to disk. AJA Ki Pro is sort of what I want but it’s pricey and I think it’s better suited to Apple rather than Win/Vegas. Sony have a hard disk that mounts on a better camera than mine. But I’m excited about the Firestore FS-200 DTE. I’ve a bit more research to do though
