Setting up trim behaviour in Video by Zaweba
Choose the large trim size, what happens past the end of the media and whether the trim monitor opens on its own, all in Video by Zaweba trim settings.

Small settings shape how an editor feels in the hand. Video by Zaweba keeps the ones that affect trimming in a single place, Edit > Trim settings, and spending two minutes there early on makes every later trim fit the way you work.
There are three choices. None of them is complicated, but each answers a question that comes up the moment you start trimming in earnest.
The large trim size
When you nudge an edit point, Alt+arrow moves it one frame. For bigger moves there is a large trim, on Alt+Shift+arrows, and the trim monitor has a button for it too. By default the large trim is 5 frames.
Five frames suits a lot of work, but not all. If you cut fast paced material where a large adjustment is often a dozen frames or more, a bigger step means fewer key presses. If you work on slow, careful pieces where a few frames is already a big change, a smaller step gives finer control while still being quicker than single frames.
Think about the rhythm of your typical cut. Set the large trim to the size of a typical correction, so most adjustments take one or two presses.
Past the end of the media
Every clip has a limit: the first and last frames that were recorded. When a trim tries to go past that point, something has to give. Trim settings let you choose. The trim can stop there, or the clip can hold its last frame for the extra length.
Stopping is the safe default. You always know a clip contains only real footage, and when a trim refuses to go further, the timeline reports "Media limit" so you understand why. That message is not an error. It is the app telling you there is simply no more recorded material on that side.
Holding the last frame is useful when you need a shot to run a little longer than it was recorded, perhaps to sit under the end of a line of narration or to fill a beat before music changes. A frozen frame for a few frames is often invisible, especially on a static shot. On a moving shot it can be obvious, so check it by playing across the cut.
If you need a deliberate held frame for longer, the freeze frame command is a clearer way to do it, because it makes a separate still that you can trim, move and treat on its own.
Opening the trim monitor automatically
The third setting decides whether the trim monitor opens when you pick an edit point. If you trim mostly on the timeline with the keyboard, leave it off so the monitor does not appear every time you click near a cut. If you do a lot of careful dialogue trimming, turn it on. One click on an edit then puts you into the trim monitor with both sides of the cut in view, ready for dynamic trimming.
Some editors switch this on for the fine cut stage and off again for rough assembly, when they are moving clips around more than trimming them.
How the settings fit together
The large trim is the step used by Alt+Shift+arrows on the timeline and by the large trim button in the trim monitor, so one setting serves both ways of working. The media limit choice decides what any trim does when it reaches the end of a clip.
Set them for the kind of job you do most and revisit them only when a project needs something different.
A sensible starting point
If you are new to the app, leave the large trim at 5 frames and keep trims stopping at the media limit. Turn the automatic trim monitor on once you start fine cutting dialogue, and see whether you like it. After a project or two, adjust the large trim to match how far your corrections usually go. These are small decisions, but they make every trim in Video by Zaweba feel more like your own.
