Reporting bugs to your engineering team. Demoing a new website. Showing off skills on a new video game. Teaching a webinar with a screencast. Training a client. There are many reasons why creators record their screens and showcase their digital workflows.
However, most viewers can process what’s happening on a screen faster than someone can navigate the web. As a result, watching a screencast in regular speed will likely seem boring and slow. Increase the tempo of your screencast video to cut to the chase and keep your viewer watching until the end of the video.
In this article, I’ll explain how to speed up a screencast using a free online tool called Kapwing. I recommend Kapwing because it's free and works on any kind of device. Kapwing's Studio allows creators to change the speed of an MP4, crop, or annotate the screencast with shapes and text.
Step 1: Open Kapwing Studio
Start by going to the Kapwing homepage and clicking "Get Started." This button will take you to the main video editing Studio.
Step 2: Upload Screencast
From the landing page, you'll have an option to upload a video or import a video from YouTube or another URL. Start by uploading your screencast.
I uploaded a mobile screencast by dragging-and-dropping the MP4 file. I had recorded this video on my iPhone, then Airdropped it to my Mac computer.
Step 3: Increase Speed
Once your video uploads to the online editor, click on the video layer and find the "Speed" tool in the right-hand panel. Click the "+" button to speed the video up or the "-" button to slow it down. The video preview will update to show the screencast sped up or in hyperspeed, depending on the amount of increase.
Step 4: Add Annotations, Voiceovers, or Other Edits
Now that you have sped up the video, make sure it looks right before clicking "Publish." Explore Kapwing's other tools, like the ability to add text, shapes, or a voiceover or background music. You can trim out the beginning or end of the video to remove excess footage, crop to focus on one part of the screen (like the red bar at the top), or search for a device image to frame the screencast and bring it to life.
Creators can choose to export their edited video as an MP4 or as a GIF by going to Settings > GIF.
Step 5: Publish and Share
Once your video preview looks right, click "Publish" to process the sped up video. Kapwing will take a few moments to process the MP4, then return the file to you. You can share it on social media directly, copy the URL to send to coworkers or friends, or download the file to save and publish late.
On the first run with Kapwing, the output video will have a small Kapwing watermark in the corner of the video. Creators can share the video with the watermark or sign in to remove it for free. Here's an example of the screencast with no watermark:
Thanks for reading! I hope this article has helped you make screencasts to share with your team or with other people to show them bugs, demonstrate app functionality, and share technical recordings. This technique is perfect for videos you film with your phone, capture on Quicktime, or record with a Chrome extension like Loom or Screencastify. Please reach out with any questions about changing speed.
