The field of video compression continues to evolve, with ongoing research and development efforts focused on improving compression efficiency while maintaining high-quality video playback. These are just a few examples of advanced video compression methods. By representing the motion information efficiently, these techniques reduce the required quantity of data to represent the video sequence. If you want to get more customizable controls to compress MP4 videos on Windows, Mac and even iOS and Android, you can take a look at the following MP4 compressor software. Part 4: Top 3 Free MP4 Compression Software. Dropping it to 2,659kbps (I asked for 3,000) reduced the file size to 20.2MB while retaining the original. Motion estimation and compensation techniques identify the motion vectors between frames and encode the differences instead of storing complete frames. Step 4: Click Download File to download the compressed MP4 file. Doing this in HDVCF reduced the file size from 165MB to 61MB, with watchable results. Motion Estimation and Compensation: Video compression often takes advantage of temporal redundancy, which refers to similarities between consecutive frames. By adapting the encoding based on the context, CABAC achieves more efficient compression than more straightforward entropy coding methods.ģ. It analyzes the statistical properties of the video data and assigns shorter codes to frequently occurring patterns and more extended principles to less common ones. Context-Based Adaptive Binary Arithmetic Coding (CABAC): CABAC is an entropy coding technique commonly used in video compression standards like H.264 and H.265. It achieves this using more advanced encoding techniques, such as larger block sizes, more efficient motion compensation, and enhanced entropy coding.Ģ. HEVC achieves higher compression ratios while maintaining similar video quality. High-Efficiency Video Coding (HEVC): The video compression standard HEVC or H.265 provides considerable enhancements. Yes, there are several advanced methods to reduce the size of a video.
