For the latest 5-6 years i had the same problem.
Video and audio goes out of sync if I capture more then about 10 minutes. The same if I export more then about 10 minutes.
It doesen´t matter what camera I use.
We have 3 different ones
Sony Hvr-A1e, Trv950 E, Pdx 10p
It doesen´t matter what computer I use. Right now we use imac 2.8 Ghz Intel Core 2 Duo. I have tried with PC the same problem.
We always upgrade the Premiere program.
It doesen´t matter if I record Dv Sp or HDV. The same problem.
The process looks normaly like this.
Record in Dv SP Ns48k or HDV1080i
Dv PAL Widescreen 48khz
HDV 1080i25 (50i)
What makes it even more confusing is that sometimes we capture 30 min in premiere and then when you play it in VLC it is not out of sync but it is in premiere???
I have seen Threads about this but no solution.
Everything works fine if we record shortclips and export less then 10minutes but when we try with longer projects 30 minutes or longer it have NEVER worked. That is the most strange thing. If it works with short projects It can´t be my settings that are wrong or???
Sorry for my terrible English
Don't use the PR capture utility. Use HDVSplit for HD (free) and Scenalyzer for DV.
Unfortunatly I can´t find this program for mac but maybe there are something similiar "out there".
Strange that Adobe can´t fix this???
Thank you anyway! :-)
