10. Video Editing Tips 1
• Always shoot with the editing in mind:
• take different shots, close shots, wide shots, hold the camera
steady, film enough footage, you can always cut out later what
you don’t need.
• Work organized:
• if you are making a longer movie, prepare a storyboard up first.
Name your clips in your video editing software. Use the same
names as you use in your storyboard. If you don’t name your
clips you will end up with a heap of files and you will lose a lot
of time trying to find the footage that you are looking for.
• First assemble:
• Once you have your footage loaded into the editing software,
start with creating a “rough cut”: put the main footage you want
to use in chronological order in the time line.
11. Video Editing Tips 2
• Cut out the crap:
• trim the beginning and endings of each clip and cut out all the
unusable shots
• Tell your story:
• where can you add close ups? What shots can you add to
enhance the effect? Try out different things and notice the
impact, effect or feeling, the emotion that the video brings
across
• Take it easy:
• Your shots last at least between 2 and 10 seconds. Vary shot
lengths, some longer shots and then some shorter ones. Don’t
go for the stroboscope effect, MTV or boredom. In about 5
seconds, the human brain has seen most details of a picture
12. Video Editing Tips 3
• Add some effects:
• bring your audience into the movie, prettify your movie. Careful:
try to “feel” what different effects do to your movie, don’t go
crazy with flipping and twirling stuff, read the language of
movies
• Create intro, opening and closing titles:
• have a proper beginning and ending, black at the end of a movie
creates a dramatic effect. When a title follows black, the
audience can relax.
• Add music and sound effects:
• test different kind of music tracks for your video and “feel” the
difference. A good choice of music will enhance your video
