[Jon] Sometimes on a show or film the first few words of the person who is speaking sentence are heard before they cut to the speaker. To me it looks like bridging two takes of audio but im not sure
I have found that If you watch a lot of old movies you can see that a dissolve is used a lot to transition from one scene to the next (first few words of the person). A dissolve helps tell the audience that there is a change in time. Fast forward to today, you will see very little dissolve transitions in a recently made movie. Dissolve can be distracting and upset pacing amongst other things. straight cuts, on the other hand do wonders, but sometimes can be distracting. The J cut can help ease into the new scene by letting the audio linger a little bit. I personally find that this can be achieved easier with SFXs. But these overlaps help make the straight cut into a new scene less jarring. At least thats how I see it. Hope this helps.
