QuickTime: How to Edit Video Files
QuickTime Player offers several options for editing your movie, including trim, split, cut/copy/paste/delete, and flip/rotate.
If you don't already have QuickTime installed on your machine, download it using one of the links below:
After downloading, run the file to install the program.
Open QuickTime and click File > Open File...
Browse your computer to find the video file you wish to edit and click Open.
Use the trim function to remove unwanted parts of your movie.
- Choose Edit > Trim. The yellow trimming bar appears, with handles on each end.
- Drag the handles to select the part to keep. You can also take these actions:
- Click the Play button to play back the part selected.
- Move quickly through the part selected by swiping with two fingers on your trackpad, scrolling with your mouse, or dragging within the trimming bar.
- Choose View > Show Audio Track to identify quiet sections of the movie.
- Click Trim. All video and audio outside the trimming bar is removed. To undo the trim, choose Edit > Undo Trim.
Use the split function to split your movie into multiple sections that can be manipulated further.
- Go to the point in the timeline where you want to make the split, then choose Edit > Split Clip.
- From here you can take several actions:
- Drag a clip before or after another clip.
- Move through a clip by swiping with two fingers on your trackpad or scrolling with your mouse. At any point in the timeline, you can choose Edit > Split Clip to split the selected clip.
- Choose View > Trim to trim the selected clip.
- Choose View > Show Audio Track to identify quiet sections of the clip.
- Select a clip and choose other editing commands from the Edit menu, such as Cut, Copy, Paste, and Delete.
- Click the Play button to play back all clips.
- Click Done. To see your clips again, choose View > Show Clips. To undo your splits, choose Edit > Undo Split Clip.
Cut, Copy, Paste, Delete
Use the Cut, Copy, Paste, and Delete commands from the Edit menu when you're editing split clips. If you're pasting a clip into another movie, you don't have to be editing clips in that movie: just go to any point in the timeline of the other movie, then paste the clip.
To quickly join movies together end to end, open the first movie, choose Edit > Add Clip to End, then select the other movie from the file dialog.
Use the flip and rotate commands from the Edit menu when you're viewing a movie or editing split clips. These commands flip or rotate the entire movie or clip.
