...my first post here so please bear with me...
First off, here are the pertinent specs of the PC I am using:
IBM Intellistation E Pro 6214-58U
1 x Intel Pentium 4, 2.2GHz processor
Windows 2K SP4
C: Seagate 100GB Barracuda ATA Internal IDE (system disk)
D: Maxtor 160GB DiamondMax Plus 9 Internal IDE (capture disk)
Video Board: ATI AIW X800XT AGP
The problem I am having with audio synch happens both in the capture phase and edit phase using Pinnacle.
In the capture phase, I am transferring via analog signal from a camcorder (Sony Digital Handycam DCR-PC115 NTSC) to the video-in of my video board. During capture it initially dropped about 100 frames a minute and during playback, audio got out of synch almost immediately. I tried it again after closing everything in the Win2K task tray and cut the dropped frames to about 50 per minute, and during playback the audio got out of synch, but it took longer than in the first capture.
Is the dropped frames due to system performance? I'm hoping the specs of the computer platform I am using are sufficient to capture from a camcorder without this kind of problem. Any suggestions on settings that may eliminate the dropped frames?
In the edit phase, I noticed that sometimes when changing the start frame of a scene to begin later than the captured start of the scene by moving the edit knob to the right, the audio also can get out of synch. This doesn't happen all the time, but in my experience this has happened twice in my editting about a dozen movies (which is a large ratio in my view).
Can I solve this by unlocking the audio track, resynching it manually and then locking it again on the scene where it got out of synch? The version of Pinnacle Studio I am using currently doesn't allow unlocking the audio track for editting, but if I spend $19.95 to upgrade it, supposedly it will. I wanted to ask if using this feature as I described above will allow me to adjust the audio synching and solve this problem, so I can avoid purchasing it if it won't.
Any suggestions/alternative solutions to solving this problem are greatly appreciated. Thanks for any help you can offer!
