The same thing happens to me.
This is a problem of capturing and interpreting Premiere.
I have the same problem when I capture with that software.
When I do that with Pinnacle I have no such problem. Pinochle however gives me the material in three different lines without multiplexing, A two-line video and mono audio. Care at that material Premiere and edit links Las lines or working with the nested sequence.
If you shoot straight Premiere. Synchronize the audio line with the respective video. But this demands more time because each cut or scene can have different measures of disequilibrium.
At the time the video camera records the, Audio takes a PAR frame. Before being registered. Leaving a small space in Silesian.
The problem is in the process of recording camcorder, As you can see the video and audio perfectly square, Both playing the cassette as in the captured video file. Higher than the image you have in the scene cuts, Image being frozen and only the audio playing, But if we move the cursor the player can see again the video and audio perfectly square.
And say that this is a problem of capturing and interpretation of Premiere failing to recognize the frames of silence in each section of the recording, As does Pinnacle.
