This walks you through the whole program with one short screen recording, from opening it to having a finished .mp4 you can put on YouTube.
Before cutting anything, see what you have.
Press Open a recording… at the bottom of the window and choose your video file.
Look at the box marked Save finished videos in. It is filled in for you with a folder that really exists. Type a different one and press Save if you want somewhere else.
Press Play and let it run to the end. Press Restart to go back to the beginning and play again.
Taking something out of the middle is two cuts and a delete.
Click the blue strip at that moment, or type the number of seconds in the box beside the clock and press Move to.
Press Cut here.
Move the playhead there and press Cut here a second time.
In The pieces, find the row whose two numbers match the part you want gone, and press its Delete.
Press Restart and watch the moment where the two pieces meet.
Clicking gets you close. Typing gets you exact.
In The pieces, change Starts at or Ends at on any row and press Set.
Ask for something impossible and it is brought inside what is possible, and told to you. An end past the end of your recording becomes the end of your recording, and the banner says so. You are never left wondering whether the button worked.
Press Go to on a row to pick that piece out, then Move left or Move right.
Rows of sound sit under the strip of pieces, on the same scale, so you can see your narration against the picture it is about.
The first row is the sound that came with your recording. Drag its slider, or type a number in the box beside it, or tick Off.
Press Add a track.
Move the playhead to the moment you want the sound to start, then press Add a sound… on that row and choose a file.
Each sound has three numbers. Starts at is the moment in the finished video it begins. Uses from and Until say which part of the sound file to use. Change them and press Set.
On your music row, tick Under the voices.
You will not hear this while editing. The window plays each row through its own player, and one player cannot listen to another and duck itself. It is done by the part that writes the file, and only there.
Two sounds cannot overlap on one row. If you want two things heard at the same moment, put the second on its own row. That is what rows are for. And when you delete a piece of picture, the sound after it moves back by the same amount, so your narration stays with the part it was about.
The project remembers your work. The render writes the file.
Press Save project.
Press Render.
Press Open folder.
Said plainly, so you know before you start rather than after.
