![]() As you change the resolution, you can decrease the video bitrate to further reduce the video file size, say, you can divide the bitrate by two if you are going to convert video from 1080p to 720p. Higher resolution usually requires a higher bitrate, hence a bigger size. Compress Large 4GB Video by Bitrate Decreasingīitrate contributes to file size greatly. Lowering the video resolution can reduce the file size significantly. Higher resolution comes at the price of a bigger file size. Compress Large 4GB Video by Resolution Downscaling In fact, you probably won’t notice any visual difference between the original video and the compressed file. This method can output video with little quality loss. The resulting file could be even smaller if it is originally coded by older codecs like MPEG-4, MPEG-2, XviD, etc. If your source video is h264 encoded, it can be reduced to half size when re-encoded through HEVC/H265. ![]() HEVC stands for high-efficiency video coding. Compress Large 4GB Video by HEVC (h265) Re-encoding ![]() Generally speaking, there are four ways to make a large video smaller. As a ten-minute 4K video would require a whopping 4GB, it’s natural that you would want to compress such large 4GB video files to save space. ![]()
