Play the class two versions of the same three clips, cut in a different order. Ask what each version says happened.

Same footage, nothing added. The order did all the work.

Today you cut your own, and then you re-cut it to see the effect for yourself.

A video editor shows your footage as a timeline: a strip running left to right, where left is the start and right is the end.

Clips sit on the timeline in the order they will play. Making a clip shorter is called trimming. Stacking one thing above another puts it on top, which is how a title sits over a picture.

Almost everything you do to a video is one of those three: order, trim, stack.

Clipchamp runs in your browser. You sign in with a Microsoft or Google account, both free. If you cannot get in, say so now rather than working through it alone.

Then bring in your clips and put them on the timeline in the order you want them seen.

Now tighten it. Trim each clip so it runs only as long as it needs to, put a transition between two clips so the change is not abrupt, and lay a music track underneath.

Keep playing it back. Editing is a loop of change, watch, change again.

Add a title so a viewer knows what they are watching, then export. Nothing you have made is a file until you export it.

Then the real exercise: change the order of two clips and watch it again.
