How to Compress Large Video Files Easily? (> 4GB)

Can I Compress 4GB Video File Online Free?

Fact: Video compression is a lossy process. You can’t compress videos without losing quality. But the good news is that compressing videos from high-quality won’t output files with serious quality damage if choosing the right program and the right method.

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 h264 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.

This method can output video with little quality loss. In fact, you probably won’t notice any visual difference between the original video and the compressed file.

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 matters if you want a smooth video playing even in slow motion. However, 30fps is more than enough for human eyes to view videos comfortably. So if you have a 60fps video, changing it to 30fps will not affect the viewing experience much but decrease the file size efficiently.

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

At the bottom of the workspace, you can click the triangle button to select an output folder in advance or leave it as default.

Step 2. Choose an Output Format

On the right side of the interface, click on the format image to unfold the output format list. Head to the “Video” section and select your wanted output format. You can keep the format as the original or try a different type.

Tips. You can choose the H265 profiles and skip step 3 if you want to preserve the video quality.

Step 3. Reduce Large Video File Size

Now, if you want easy and fast compression, you can return to the main workspace and use the bottom compression button to compress your files. Simply click the button and drag the slider to the right to set the compression ratio. As you change the ratio, you can preview the output size from the task list. Note that this way reduces the bitrate of your video so the quality will drop to some degree depending on how you set the compression ratio.

Alternatively, you can modify the settings, including the codec, resolution, bitrate, and frame rate in the “Parameter settings” to compress 4GB video files to MB.

Step 4. Export the Compressed File

Finally, hit “Run” to convert the 4GB video file to a reasonable size.
