I use the bach capture feature. I frist hook up my DV camera and in the capture window, I play the tape. When I see a scene that I might use, I set the in and out points. and save them . When I save them, I give it a description I can that helps me in the final edit. With Pro, you can search fairly well for words that you entered during capture. I usually enter the descriptors in the description part of the save dialog box and then search later there. I have actually one huge project with all my films in it and when I want to find scenes of my daughter, I use the find feature. Aynway, back to the capture window. In the timecode portion of the capture window (lower right) I set my in point by clicking on “Set In”. I hit the start button, not the record button!!!. I preview the scene and when the scene changes I hit the !Set Out” button. Then I hit the Log Clip button and enter all the information I need. I do this for all the tapes, in your case all 4 hours.
When _I have doene this and finished my story board, I then highlight the offline clips and hit F6 or File -> Batch capture. All of the clips that were offline and highlighted will now be batch captured. Premiere will prompt you to enter the correct tapes, but that’s all. And, the best partt, the batch capture will be performed in the background. Hope this makes sense and it really got me organized.
