What is the purpose of these buttons ? I can’t understand why they are here.
Nudge is to get more accurate positioning instead of using a mouse, so you can refine edges and tracks.
Yes I got that… but what is the purpose of these 4 buttons : up down right left ?
I thought it was to move more precisely the relative track, but nothing moves
You’re going to have to show me where in the interface you are talking about.
We have two different types of nudges. We have nudge as a control on the keyboard that affects splines when rotoscoping and nudge in Adjust Track. You didn’t specify.
If you let us know specifics up front or include screenshots we don’t have to ask for clarification. We can’t see your screen and context. This screenshot helps.
In Adjust Track, these nudge keys are for micro adjustments to the points you are using to correct your track. They are still used to get more accurate positioning instead of using a mouse, so you can refine the track better. It is especially useful for aligning the current frame exactly to the master frame in Adjust Track.
Does that make sense?
