How to compress a video file without sacrificing quality
These days digital SLR cameras, next-gen GoPro devices, and smartphones can record HD Ready and FullHD or even high-quality 4K video.
But every footage shot in FullHD takes up an indecent amount of space on your device, not to mention 4K, which consumes 16GB of memory on iPhone 6 in 35 minutes. When the space on the memory card or the internal memory of the device runs out, each of us experiences that feeling of disappointment with the size of the memory of our device, that we involuntarily think of the minimum of a larger card or even of a new device. which will be able to compress the footage at least minimally. It is good if you have a computer with a large volume of discs to create a video file. But even this volume will end sooner or later.
I propose to consider how to compress a video file without sacrificing quality. And for that, you need to understand that there is a strict balance between video size and quality:
correct settings of the video converter will preserve the quality of the video and reduce its size;
incorrect settings will reduce the quality of the video, but will not reduce its size.
How to reduce the size of the captured video without losing quality.
How much disk space does HD Ready, Full HD, 4K video take up?
The video performance of modern devices has reached very serious heights. And shooting in Full HD at 30 frames / second is a standard and a necessary requirement for any digital camera. All smartphone flagships can shoot in Full HD, practically no less than the resulting image quality from SLR cameras.
And how much space is required for different video formats to shoot. No one will tell you the exact indicators, I will give you some rough data that you can trust when choosing a recording device and video format.
On average, it takes 1 minute of video:
When shooting in HD Readry (720p) at 30 frames / second – 60 MB;
When recording in Full HD (1080p) at 30 frames / second – 130 MB;
When recording in Full HD (1080p) at 60 frames / second: 200 MB;
When recording 4K (UHD) at 30 frames / second: 375 MB.
The difference between HD, UHD, 4K and 8K video formats plays a decisive role in determining recording volumes. But there are other parameters that the video file size depends on: audio parameters, bit rate, aspect ratio, color resolution, and more.
I would not recommend reducing video on smartphones unless absolutely necessary, because no smartphone can save the optimal video quality and compress the video file as much as possible. For the video reduction process, there are optimal computing solutions that cope with this task successfully. Today I will consider one such tool, which very simply and quickly allows you to reduce the size of a video file without compromising on quality.
