About Large Video Compression

HD videos often have large file sizes. 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. Generally speaking, there are four ways to make a large video smaller.

A. Compress Large 4GB Video by HEVC/H265 Re-encoding

HEVC stands for high-efficiency video coding. If your source video is H.264/MPEG-4 AVC encoded, it can be reduced to half size when re-encoded through HEVC/H265. The resulting file could be even smaller if it is originally coded by older codecs like MPEG-4, MPEG-2, XviD, etc.

Tips: The latest AV1 codec provides even higher compression than HEVC, but encoding video to AV1 will take much more resources and time.

B. Compress Large 4GB Video by Resolution Downscaling

Higher resolution comes at the price of a bigger file size. Lowering the video resolution can reduce the file size significantly.

C. Compress Large 4GB Video by Bitrate Decreasing

Bitrate contributes to file size greatly. Higher resolution usually requires a higher bitrate, hence a bigger size. 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.

D. Compress Large 4GB Video by Frame Rate Dropping

Frame rate is related to the smoothness of the video. However, 60fps is more than enough for human eyes to watch videos comfortably. So changing 60fps to 24fps, the standard frame rate for normal videos, will definitely reduce the file size.

Tips. You can also crop or cut out the unnecessary parts from the video to reduce video size from high GBs to low MBs.

You can pick one of these methods or use them combined to shrink your 4GB video files. But to do this, you'll need a proper video size compressor to help you. The next part offers a top-rated 4GB video compressor that can make your large video compression process a lot easier. Just read and follow.
