How can I compress MOV video files over 1gb to small size on PC or Mac?

A MOV file larger than 2GB can be difficult to upload, transfer, or store, so how to compress mov over 2GB mainly comes down to choosing an efficient video encoder and balancing quality against the target file size. VidCoder is , open-source Windows transcoder that provides a graphical interface for configuring video and audio encoding.

Set the Target：

• Import the MOV file and first check its duration, resolution, and current file size. Decide whether your priority is simply getting below 2GB or making the file considerably smaller, because this affects which encoding method you should use.

Configure the Video：

• Open the encoding settings and select an H.265/HEVC encoder for better compression efficiency. For quality-based encoding, choose a reasonable constant-quality setting and make a short test encode first. A value around RF 20 can be a starting point, but the appropriate value depends on the source and does not guarantee a specific output size.

Reduce the Audio Size：

• Check the audio settings and use a compressed format such as AAC when appropriate. A bitrate around 128 kbps can reduce audio size for ordinary stereo content, although higher-quality or multichannel audio may require different settings.

Encode and Compare：

• Choose the destination file, start the encode, and wait for processing to finish. Compare the resulting file size and visual quality with the original. If the output still exceeds 2GB, adjust the video bitrate or quality setting and encode again.

The important distinction when considering how to compress mov over 2GB is that constant-quality encoding controls visual quality rather than guaranteeing an exact file size. If staying below a strict 2GB limit is essential, target-bitrate or size-based calculations are more appropriate.
