How to Compress Video “Lossless” (Reduce Video Size) Part 3
How much space does HD Ready, Full HD, 4K video take up?
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.
Lossless video compression software
Hand brake
It is a free converter that converts video files of almost any format to mp4 (both DVD and Blu-Ray disc). Contains settings for popular tablets, androids, devices like iPhone, AppleTV, etc. Output file types:
video codec (H.265 (x265), H.264 (x264), MPEG-4, MPEG-2 (libav), Theora (libtheora), VP8 (libvpx);
Audio codec (Flac, AAC, CoreAudio AAC / HE-AAC (OS X only), MP3, Vorbis, or AC3)
audio tracks (DTS, AC-3, DTS-HD, MP3, AAC);
container (MKV and MP4 (M4V)).
For example: this program compresses HD video with mov format and sizes from three to four GB (duration 35-40 minutes) in mp4 format to 200-250 MB without losing its quality.
How to set up HandBrake correctly
Having launched HandBrake, you can see a lot of incomprehensible settings and what to do? Sooner or later you will realize, the main thing is to make an effort. So in this program you can edit videos and their sound.
Prepare your video for compression. Click the “Open Source” button and click the “File” item. Now we select our video.
The program contains blanks made by the developers, these are so-called presets. They mean ready-to-use parameters for any device or service. Very useful for those who do not want to dig deeper and understand the settings.
Each preset represents custom audio and video settings for iPhone, Android, Windows Phone, and other devices. Also, if suddenly this is not enough for you and you want to fine tune one or another parameter, after tuning it you can save your preset, which you can then use many more times.
Next, take a look at the most important features of Handbrake to manually configure the video conversion parameters.
In HandBrake, you can adjust the audio parameters. There is an “Audio” tab for this. In fact, audio can take up a lot of space in a video, especially if it is of good quality. In a simple video, so to speak, for the house, you can remove unnecessary tracks and leave only the first one. We configure “MP3” as codec. This will reduce the size of the sound while maintaining quality. We set the bit rate to 160, the sound quality will not be very good. If sound is important, set it to 320.
Choosing the best video container and codec
Ideally, when recording video, you should always set the maximum video settings for the device you are recording with. Only the maximum of a video camera will allow you to get the highest quality video, which can then be compressed with almost no loss of quality. The basis for video reduction is to use the most efficient codec and container for the video.
