After you've found iMovie in your Applications folder or re-downloaded it, follow these steps to compress a video. It comes standard with macOS, but if, for some reason, it's not on your computer, you can download it from the Mac App Store. Better Quality: This option ensures a better quality of the compressed. One of the most popular ways to compress your videos is with the iMovie app. The lower the video quality, the smaller the file size. You can compress a video on Mac with iMovie by adjusting the quality. iMovie is the built-in video editor on Mac. Faster Encode: This is the quickest way to compress any video, but it slightly reduces the video quality. Way 2: How to Compress Video on Mac by iMovie. It works with almost any format and outputs a compressed MPEG-4 (MP4) file. 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. As the name indicates, Compress is a video compressor app that reduces the size of videos. 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. Motion estimation and compensation techniques identify the motion vectors between frames and encode the differences instead of storing complete frames. 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.
