Explanation:
Detailed explanation-1: -For applications where it’s important to retain the quality of the file, lossless compression is the better choice. The drawback of this compression technique is that larger file sizes are required to maintain post-compression quality.
Detailed explanation-2: -Lossless-reduces file size by identifying redundant patterns in video data and replacing duplicates to references to earlier instances. This process ensures that no data is permanently lost. Videos compressed with lossless compression tend to be larger than those compressed with lossy.
