Watch two versions of the same three clips, cut in a different order. What does each version say happened?
Version 1
Version 2
Same footage, nothing added. The order did all the work.
Today you build your own sequence. Next lesson you finish it, and 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. Rows play at the same time: music on its own row plays under the pictures, and a title on its own row shows over them.
Almost everything you do to a video is one of those three: order, trim, layer.
Snip Studio runs in your browser at snipsound.com/video-editor. There is no account to make and nothing to install, and your clips stay on your own computer.
Then bring in your clips and put them on the timeline in the order you want them seen.
No clips saved from the sourcing lesson? Take three minutes now and grab two or three short ones from Pixabay, the same way you did then, and check the licence before you download.
For the music, use the thirty-second clip you made in the AudioMass lessons. If you do not have it, download one short music track from Pixabay the same way.
Now tighten it. Trim each clip so it runs only as long as it needs to, and make the music end with your last picture.
Keep playing it back. Editing is a loop of change, watch, change again. Then name your project, so it is there to finish next lesson.
You have a sequence: your clips in order on one row, the music on the row underneath, each cut to a deliberate length.
Nothing here was invented. Every decision was about what to keep, how long to keep it, and what comes first. That is editing.
What would change if your first clip ran twice as long?
