Posts about visual media.
In this post, I will share how to add an audio visualizer to a video, easy and free of charge. Here’s an example:
For that purpose, I use Microsoft Clipchamp video editing app. The web-based app is available on laptop and desktop computers through a web browser like Google Chrome or Microsoft Edge. Currently, Clipchamp isn’t available on phones.
Here’s how you can easily capture and extract an image from a video in Windows 11 using the Windows’ default Photos app.
On iPhones, you can easily convert 4K videos to smaller 1080p video files for free and without using a 3rd party app. To do that you only need a simple Apple Shortcuts video conversion script.
In all relevant video recording apps on iPhones and Android phones, as same as in modern real cameras, there are video recording quality settings featuring resolutions such as 1080p and 4K and frames-per-second (fps) rates such as 24, 30, and 60. Here I’ll try to explain simply what they mean in practice.
While recording videos on my iPhone 11 with the default Camera app, I have been oftentimes experiencing a flickering problem. The flicker can be especially visible in bright video scene areas like skies or white walls when the lighting conditions in the scene change. For instance, when you move the focus of the camera from dark to bright areas of the scene or vice versa.
Many iPhone users report the same issue with other iPhone models, such as the iPhone 12 and 13 series. From watching phone camera videos on YouTube I have learned that some Android phones may have similar problem.
By the way, this flickering is different from the common flickering caused by LED light, which is fixable with the camera’s shutter speed change to match the frequency of the LEDs.
Here’s how you can resize or reduce dimensions of photos and images from your iPhone’s Photos and Files apps and consequentially reduce their file sizes. You can do that using Shortcuts scripts – simply, for free, and without installing 3rd party apps.
