HDVSplit for HDV and Scenalyzer for SD.
Sorry, I meant using Premiere Pro to capture.
That was clear, but PR can't do that with HDV. That is why I suggested HDVSplit, since that does what you want and what PR should have offered years ago but still does not. Best of all, it is free, has no OOS errors, offers scene detection, has preview and works.
If you have a Volkwagen Beetle and you need to tow a 5000 Lbs trailer over hilly terrain, that is far from ideal (PR). Now if you neighbour lends you his Dodge Ram for free to tow that trailer, does that make life easier? (HDVSplit).
In PPRO and if you are capturing SD . ( you did not tell us what).
Scene detect will capture from Camera Start to Camera stops ( takes).
Otherwise...what Harm said. (Not sure about the trailer analogy!)
3 hour long video clip must be analog source.
Have a look at Scenalyzer it does optical detection.
I downloaded HDVSplit but it does not allow me to capture specific clip lengths. I do not want a 3 hour clip and I do not want clips split by scenes. I want 10 minute clips, just like scenalyzer allows me to do with SD footage.
