Howdy Grandma!

Let me guess:

1. You used “Capture NOW” when you input the tape.
2. You captured LONG sections of the tape instead of short scenes.
3. You shot with a Canon camcorder.
4. The audio on the camcorder is set to 32 kHz (12 bit) and not 48 kHz (16 bit).

The above reasons (alone, or in combination) are the main reasons for Audio/Video “slippage”.

When the audio gets far enough “off” that you want to fix it (AFTER you edit the scenes to the timeline) use the “Razor Blade Tool” to cut the audio track in two or more sections, then just SLIDE the audio (using the Arrow cursor) into sync with the video.
You may need to do this several times during the edit. It gets easier after you fiddle with it a while.

Back when I edited numerous exercise videos that were shot at a particular number of beats per minute (BPM) using pre-recorded songs, then in post, had to change the songs to different ones that were new recordings, I found that often, the bpm would creep out of sync with the original songs. I found that by fixing the timing first, then editing, it saved a lot of time.

Before this knowledge, I would edit the video and constantly have to slip the audio or video and I never knew how much to slip it.

After this knowledge, I found that during one song, it would be off by the same amount over a certain period of time. In other words, if I had to cut 3 frames of video out at 10 seconds into the clip in order to get it back into sync, I knew that every 10 seconds of song, I would make a cut in the video and trim it by 3 frames. This meant that I didn’t even have to watch or listen to the remaining edits that closely. I would just do the editing, and 9 out of 10 times, I wouldn’t have to slip by a single frame afterwards. I would then cover the cut with another camera. I didn’t have to keep the cut at the same place, but I did have to use that 10 second mark, or whatever it happened to be for that song, then I could move the edit point around by a second or 2 on either side of the original 10 second edit and it was OK.

Feels like I’m rambling a little, but the point is, doing this, you don’t end up fumbling around during an entire long clip to continually figure out how far it’s out of sync. Just take some time to find out how much it’s off at a given duration, then make the edit, move your play head that far again, make another edit just like before, move the play head again by the same amount and make another identical edit, and so on to the end of the clip. Then go back and slip either the audio or video edits around if desired to get them to a more pleasing frame, then cut, copy, paste, or another method would be to nest that sequence into another and edit that nest as if it were the clip.

Hope this helps,
Gary
