Part 1. Introduction of 4GB Video File Compression
There are several ways to down size the 4GB video file.
1. Lower video resolution, bitrate and frame rate.
First of all, the 4GB movie file or video recording can be downsized by lowering the resolution, bitrate and frame rate of the video file. It is the most common method to compress a video file. But you have to bear in mind that heavy reduction of video resolution and bitrate leads to quality degradation.
2. Take advantage of high efficiency video coding.
Compressing large video file and re-encoding it in HEVC codec can make the file smaller without visual quality loss. HEVC codec is a well-known high-efficiency video coding technology, which halves the file size at the same quality level compared to H.264. However, videos encoded in HEVC are not well compatible with all players or devices. For instance, you have to install HEVC video extension from Microsoft for smooth HEVC playing.
3. Cut off unnecessary part of the 4GB video.
It's highly advised to remove unwanted parts of the video file. Most video editing tools offer the Crop and Cut features to fit the bill. By doing so, it will reduce the file size of the 4GB video with your image quality untouched.
