Tips for Perfect Video Speed Adjustments 

  • Consistency is Key: Ensure that the speed changes are smooth and consistent throughout the video to avoid jarring transitions.
  • Enhance with Music: Pair your sped-up or slowed-down video with appropriate music to enhance the overall effect.
  • Use Sparingly: While changing video speed can add a unique touch, overusing them can distract from the main content. Use them to highlight key moments or create a specific mood.

These apps offer features to adjust the speed of your videos to make them faster, among other editing capabilities.

How can I speed up an existing video?

To speed up an existing video, you can use video editing apps that offer speed adjustment features.

Here's what to do:

  • Start by picking a video editing tool and bringing in your video.
  • Find where you can change the speed within the editing tool.
  • Apply the speed change to your video clip.
  • You can usually speed things up by moving a slider.
  • Watch a preview of the video to check how the speed change looks.
  • Make sure the sound still sounds right after you've sped things up.

How can I make my video 10x faster?

To increase the speed of your video by 10 times, you'll need a video editing tool capable of significant speed adjustments.

However, among our 12 recommendations, none allow for a 10x speed increase, with 8x being the highest limit available.

If you do happen to find an app that can accelerate your video by 10 times, here's how you can do it:

Here's how you can do it:

  • Open your video in a video editing software or app that supports speed adjustments.
  • Locate the speed adjustment feature within the tool.
  • Increase the speed setting to 10x or input "10" as the speed multiplier.
  • Apply the speed change to your video.
  • Preview the video to ensure the speed adjustment appears as desired.
  • Save or export the video with the new speed setting applied.

How do you make a 2x speed video?

Let's use YouCam Video as an example.

  • Begin by uploading the video you wish to speed up.
  • Next, tap on the video clip to access the speed editing option.
  • Adjust the slider to double the speed of the video (2x).
  • Preview the result to see whether it meets your expectations, and double-check the audio for any changes.

And that’s how you make a 2x speed video.

How can I speed up a video without affecting audio pitch?

When you speed up a video, a common problem is that the audio can sound weird.

But you can prevent this by using a professional video editing app that has a feature for stretching or compressing time.

This lets you change the video's speed while keeping the audio pitch the same.

Or you can also speed up your audio until it matches with the adjusted video. 

How to slow mo a video on iPhone?

Slow mo a video on iPhone by using YouCam Video.

  1. Download the YouCam Video app.
  2. Import the video you want to slow mo.
  3. Tap on Speed and use the slider to change video speed. When you adjust to below 1.0x speed, this means you are slowing down your video. 
  4. Once you're happy with the slow mo effect, tap on the checkmark to save.
