Part 3. External Knowledge for Video Compression

To make full use of iShareSoftware MP4 File Compressor, I'd like to briefly explain the basic video parameters and the recommended settings to reduce MP4 file size.

  • Change Frame Rate: If your video footage is exceeding 60 Frames per second, you should maintain the video’s native frame rate. Always choose a constant frame rate instead of a variable frame rate.

  • Control Bitrate: Bitrate is responsible for maintaining the video clarity and file size. Ideally, for getting a compressed video, you should choose the given bitrates according to your file type. For SD, it should be 2,000-5,000, 5,000-10,000 for 720p and 10,000-20,000 for 1080p.

  • Appropriate Resolution: Set your resolution to the lowest so that your video is in the smallest file size. The ideal ones would be 640 x480 for SD, 1280 x 720 for 720p HD, 1920 x 1080 for 1080 HD and 2560 x 1440 for 2K.

  • Audio Codec: For the best results concerning obtaining a compressed video, the audio should be encoded at 320 kbit/s, and using AAC-LC is recommended to be used for audio codec.
