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 build the sequence. Next lesson you finish it and re-cut it to see the effect for yourself.
Download all three before you start. Each opens in a new tab; use the download control in the player to save it.
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.
| Word | What it means |
|---|---|
| Clip | One piece of footage or sound sitting on the timeline. |
| Track | One row of the timeline. Stacked rows play at the same time, which is how an overlay or a soundtrack works. |
| Trim | Making a clip shorter by dragging its edge in. |
| Playhead | The vertical line showing which moment you are looking at. |
Keeping the base video, the overlay and the sound on separate rows means you can change one without disturbing the others. That is the whole reason editors stack them.
Open Clipchamp and sign in, then build the stack: base video, overlay above it, sound below.
Now cut each clip to the length it needs. Drag the edge of a clip inwards to trim it; the timecode shows the length as you drag.
| Clip | Trim to |
|---|---|
| Ring of Fire (base video) | 6 seconds |
| Computerised Globe (overlay) | 4 seconds |
| Special effects music | 6 seconds, matching the base video |
You have a sequence: three pieces of media, stacked on separate tracks, each cut to a deliberate length.
Nothing here was invented. Every decision was about what to keep, how long to keep it, and what sits on top of what. That is editing.
What would change if the globe ran the full six seconds instead of four?
