Following are the advantages of Video Compression:
- Occupies less disk space.
- Reading and writing is faster.
- File transferring is faster.
- The order of bytes is independent.
Following are the disadvantages of video compression”
- Compilation need to be done again for compression.
- Errors may occur while transmitting data.
- The byte / pixel relationship is unknown
- Has to decompress the previous data.
Compression can be both internal and external. Internal compression is data compression within a file format, like the data compression found in image or video files. External compression involves compressing files or folders as a whole using software tools, such as ZIP or RAR, to reduce their overall size for storage or transfer.
Compression is typically applied to reduce the size of data files or to speed up data transmission by removing redundant information. It is commonly used in areas such as file compression, image and video compression, and network communications to optimize storage space and improve data transfer efficiency.
Data compression techniques are used to reduce the size of files and data for efficient storage and transmission. Common methods include lossless compression, which preserves all data accurately, and lossy compression, which sacrifices some data to achieve higher compression rates. Examples of compression algorithms include ZIP for general purpose compression, JPEG for image compression, and MP3 for audio compression.
The areas of compression are lossless compression and lossy compression. Lossless compression reduces the file size without sacrificing any data quality, while lossy compression reduces the file size by discarding some data, which may lead to a decrease in quality.
Compression ratio in engineering can be calculated by dividing the total volume of a system before compression by the total volume after compression. In computing, file compression ratios are calculated by comparing the original file size to the compressed file size.

The video coding format MPEG is used through the web for video compression. MPEG goes up to MPEG- Part4 that is shortened to MP4.
The compression used will depend on what you want to do with the video. MPEG-2 is used for burning to DVD's. MPEG-4/H264 can be used for streaming from a website. The length of the video and available bandwidth are also considerations when selecting a suitable compression format.
The biggest advantage of compression is the fact that more data and other files can fit on smaller amounts of storage. A disadvantage is the quality lost when compressing.

The disadvantage of multiple file compression is that you need to decompress everything, even if you only need one file.

To effectively use Apple Compressor for video compression and encoding, first import your video file into the software. Then, choose a compression setting that balances file size and video quality. Customize settings such as resolution, bitrate, and codec to suit your needs. Preview the compressed video before exporting it in your desired format. Experiment with different settings to find the best balance for your specific video.
