H.264 and H.265, also known as MPEG-4 AVC and HEVC (High-Efficiency Video Coding), respectively, are two popular video compression standards used to reduce the file size of videos. H.265 is the successor to H.264 and is designed to provide better video quality at lower bit rates compared to its predecessor. This is accomplished by using more advanced compression techniques, such as larger block sizes, better motion compensation, and improved prediction algorithms.
One of the main benefits of H.265 over H.264 is that it requires less storage space while maintaining the same level of video quality. This is particularly useful for high-resolution videos, as they require more storage space due to their larger file sizes. However, H.265 requires more processing power to encode and decode videos, which can be a limitation for small hidden cameras. Ultimately, the choice between H.264 and H.265 compression will depend on the specific requirements of the project, such as available storage space, desired video quality, and available hardware resources.
