H.265 achieves this through more sophisticated algorithms that analyze and represent video data, resulting in smaller file sizes. Employing H.265 enables the creation of 4K MP4 files that are significantly smaller than those encoded with H.264, facilitating easier storage and distribution. For example, a 4K movie encoded with H.265 may be half the size of the same movie encoded with H.264, without noticeable visual degradation.
-
Bitrate Management
Bitrate, measured in bits per second (bps), directly impacts file size and visual quality. A higher bitrate allocates more data to each second of video, resulting in improved quality but also larger file sizes. Efficient encoding involves selecting the optimal bitrate for a given video to achieve the desired balance. Variable Bitrate (VBR) encoding is often employed, dynamically adjusting the bitrate based on the complexity of the video scene. Complex scenes with rapid motion require higher bitrates to maintain clarity, while simpler scenes can be encoded at lower bitrates without perceptible loss of quality. This adaptive approach optimizes file size without compromising the overall visual experience.
