To decrease high space video to low space video for Android, iPhone iPad, H.264 MP4 will be the most suitable format. For newer devices, H.265 HEVC is suggested as it's half the size of H.264.

3. Reduce video size for YouTube/Whatsapp/web: each video-sharing site imposes different limits on the sizes and formats. First, if H.265 is supported, then go for it.

Video size = bit rate * length. Beyond this equation, video size involves various video audio parameters. You can adjust those video settings to reduce video file size on Mac.

1. Bit rate. Bit rate is the number of pits that are processed in a given amount of time. Bit rate will directly affect the size. Higher bit rate means larger file size and better video quality, and lower bit rate refers to smaller file size but less quality. Lowering bit rates is an efficient way to shrink video size on Mac. To ensure good output quality, it's safe to lower the bit rate to one level below the original setting.

2. Resolution. Resolution refers to the number of pixels in an image, for example, SD 720 X 480, HD 1,920 X 1,080, 4k UHD 4096 x 2160 and 8K FUHD 7680 X 4320 pixels. The higher the resolution is, the larger the file size will be. To reduce the file size of 4k movies downloaded, or 4K clips recorded by cameras, you may need a video resolution converter.

3. Frame rate. The higher number of frames will bring smoother motion effect. Therefore, video in 60fps will result in higher video quality compared to 24fps. But the more frames will significantly increase the file size.

4. Sampling rate. Sampling rate is the number of samples of audio carried per second. The higher quality requires more samples. Simply put, the higher sampling rate will result in higher audio quality as well as the larger file size.
