Speeding up or slowing down a video is commonly used in editing. Here we will show you how to change video speed in Filmora on Mac.
Change Video Speed with Uniform Speed
Using the Uniform Speed feature, you can adjust the speed of the selected clip to the same rate.
Get to the Uniform Speed Panel
Choose the video in the timeline and click the Speed icon from the toolbar above it. Select the Uniform Speed option.
Change Video Speed to Constant Speed
Drag the Speed slider to the right or left to speed up or slow down the playback speed. Optionally, you can enter your preferred value in the Duration field to get a more precise output.
Preview the Video and Save
Click the Play button in the Player or press the Space key to preview the modifications.
It is recommended to enable Maintain Audio Pitch option to keep the video's audio sound natural.
Modify Video Playback Speed with Speed Ramping
In addition to constant speed changes in Uniform Speed, you can create variable speed effects with Speed Ramping, where a clip's playback speed changes dynamically. You can set up different playback speeds for each portion of the video.
Go to the Speed Ramping Panel
Click the Speed icon again, and select the Speed Ramping option, and then you will see a couple of options in the property panel on the right side of the interface.
None: Apply no speed ramping.
Customize: By default, five-speed points allow you to customize the speed exactly the way you want.
Montage: Six speed points in the playback speed of the selected video: 0.9x, 0.9x, 6.9x, 0.3x, 1.0x, and 1.0x, which present a slow, slow, fast, slow, and normal rhythm.
Hero moment: Eight-speed points in the playback speed of the selected video: 1.0x, 1.0x, 5.4x, 0.5x, 0.5x, 5.4x, 1.0x, and 1.0x, which present a normal, fast, slow, slow, fast, and normal rhythm.
Bullet time: Six-speed points in the playback speed of the selected video: 5.2x, 5.2x, 0.5x, 0.5x, 5.2x, and 5.2x, which present a fast, fast, slow, slow, fast, fast rhythm.
Jumper: Five-speed points in the playback speed of the selected video: 0.6x, 0.6x, 6.0x, 0.6x, and 0.6x, which present a slow, slow, fast, slow, slow rhythm.
Flash in: Four-speed points in the playback speed of the selected video: 5.2x, 5.2x, 1x, and 1x, which present a fast, fast, normal, normal rhythm.
Flash out: Four-speed points in the playback speed of the selected video: 1x, 1x, 5.2x, and 5.2x, which present a normal, normal, fast, fast rhythm.
Select and Customize Speed Ramping Preset
Please select one of the presets to apply variable video speed and customize it based on your needs. Variation in the speed will remain effective until the Play head reaches the next speed point. The speed of the video will gradually change as the Play head moves between the speed points.
Adjust the speed of the section: Drag the speed point up or down to increase or decrease the speed of the section.
Adjust the range of the section: Drag the speed point left or right to change the portion applying the speed.
Add speed point: Place the play head to the point you want to change the speed, and then click the Plus + icon on the left to add a speed point.
Delete speed point: Select the speed point and click the Plus – icon to remove it.
Add a freeze frame: Place the play head to the point you want to freeze, and then click the snow icon to add a freeze frame feature. Set up the freeze time and click Apply to save.
Preview the Video and Save
Press the Space key or click the Play button in the Preview window to preview the modifications in the video. If you want to remove the settings, click Reset. You can also save the speed ramping setting by clicking the Save as a custom button.
If the Uniform Speed and Speed Ramping options are not visible, try upgrading Filmora to the latest version.
Change Speed in Timeline
You can also change the speed in the following paths:
- Right-click the video in the timeline and select Uniform Speed or Speed Ramping on the context menu.
- Choose directly the speed options (0.01x to 100x) from the Slow or Fast menu above the Speed icon.
