Step-by-Step Instructions

Import and Select Your Video

Open Pimosa and click New Project. Import your video by clicking the + Add Media button or dragging your file into the timeline. Click on the video clip in the timeline to select it - you'll see a blue outline around the selected clip.

Ensure your video is in a supported format (MP4, MOV, AVI) for best results.

Access Speed Effects

With your video selected, click on the Effects tab in the right panel. Scroll down to find the Speed Control section, or use the search bar and type speed to quickly locate speed-related effects.

Choose Speed Adjustment Method

In the Speed Control panel, you'll see two options: Uniform Speed for consistent speed changes, and Variable Speed for creating speed ramps. For basic speed adjustment, select Uniform Speed.

Variable Speed is useful for creating dramatic slow-motion or time-lapse effects with smooth transitions.

Adjust Speed Value

Use the Speed Multiplier slider to adjust your video speed. Values below 1.0 create slow motion (0.5x = half speed), while values above 1.0 create fast motion (2.0x = double speed). You can also manually enter a value in the input field next to the slider.

Common speeds: 0.25x for dramatic slow-mo, 0.5x for subtle slow motion, 2x for quick pace, 4x+ for time-lapse effects.

Configure Audio Settings

Below the speed controls, check the Maintain Audio Pitch option if you want to preserve the original audio tone. Uncheck Include Audio if you want to remove audio entirely from speed-adjusted clips.

For extreme speed changes (below 0.5x or above 3x), consider removing audio as it may sound distorted.

Apply and Preview

Click the Apply Effect button to apply your speed changes. The timeline will automatically adjust to show the new clip duration. Use the Preview button or press Spacebar to play and review your speed-adjusted video.

Fine-tune and Export

If needed, select the clip again and return to Speed Control to make adjustments. Once satisfied, click Export in the top menu, choose your desired format and quality settings, then click Start Export to save your speed-adjusted video.

Higher speed multipliers (fast motion) will result in shorter video files, while lower multipliers (slow motion) create longer files.

Common Issues & Troubleshooting

Speed effect not applying to video

Ensure the video clip is properly selected (blue outline visible) before accessing Speed Control. Try clicking directly on the clip in the timeline rather than the preview window.

Audio becomes choppy or distorted after speed change

In Speed Control settings, try enabling Maintain Audio Pitch or disable Include Audio entirely for extreme speed changes. Consider adding background music separately.

Video quality degrades after speed adjustment

Check your export settings and ensure Hardware Acceleration is enabled in Pimosa preferences. For slow-motion effects, your original video should have a high frame rate (60fps or higher).

Speed changes create jerky or stuttering playback

This often occurs with low frame rate source videos. Try reducing the speed change amount, or use Frame Interpolation option in the Speed Control advanced settings to smooth motion.
