I have also decided on key-wording for retaining several in and out points on a clip.
Specifically for the reason mentioned earlier, quite often for different versions of an edit you will want to have different length versions of a talking head. So quite often the in / out points will overlap so using favourites will not work in this case.
Either by using control+1-9 for preset keywords, or hitting command+K and type in the first sentence the person says.
Then to keep the events browser tidy I create a folder (eg interviews) and drag all the keyworded items in there.
I’m sure everyone will find a way that works for them best.
Cheers,
Brendan
