So, im new to video editing, im about to start vlogging. I notice on vlogs theres an effect, its like some one talking, sitting in a chair, seems like when they switch points when theyre talking, seems like a new clip comes on, even tho its them in the same spot? Does that make sense? My friend told me it was called cuts, but ive been searching and that brings me back nothing.
Straight cut is a change of shot without transition effect. Jump cut is a straight cut between two very similar shots, which would be perceived as a single shot if not for a slight change in position or lightning.
Professionals used to consider jump cuts a sign of an amateur, unacceptable for movies and broadcast TV. In the 1960s the French New Wave directors broke a lot of movie rules, including the "no jump cuts" rule. Nowadays you can see them in most vlogs, although the professionals still try to avoid them by using cutaway, which usually is sourced from B-roll.
Just to add on to what Rusty Core has already said in their excellent answer...
With vloggers there's a good chance that it's not a different clip that 'comes on'; it's the same take but the vlogger/editor has chopped out some content, which results in the jump cut (usually it's a pause or they've said something wrong or they just want to remove something that they have said). This is easier than constantly stopping and starting the recording every time you pause or make a mistake - you carry on shooting and then just trim down the take in the edit.
Of course, that's not a hard and fast rule and you will see times when there are more than one take - especially if the vlogger is making an addendum/amendment to something that they previously said.
The most important thing to remember with vlogging is that it's a very open and free-spirited form of content creation. There are almost no rules and doing things your way is one of the defining traits of vlogging.
