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. This converter cannot support encrypted or protected video files.Yes, there are several advanced methods to reduce the size of a video.If the file upload process takes a long time or is unresponsive or very slow, please try to cancel and resubmit.Before uploading, please make sure you agree to the terms of this website.The maximum upload file size is 200 MB.Please make sure the desired video size is not too small (compared to your original file), otherwise the compression may fail.For example, if you need a file of no more than 20 MB, you can enter 19 MB in the "Desired Video Size" value. If you need a file size that must be below a certain value, you can enter a value slightly lower than value as the "Desired Video Size" value.If the audio quality of original video is below this value, the original audio quality will be used. Audio quality can be 32kbps, 48kbps, 64kbps, 96kbps, 128kbps or No Sound (silent).The tool will prompt you if this value is less than 30% of source file size, and you can decide whether to continue. Desired video size is an approximation value, the file size of output video will be close to this value, it cannot be greater than the source file size.

Enter a desired video size that you need.After you select your video, the "Source Video Size" will show the size of the original file, the default value for the "Desired Video Size" option will be 20% smaller then the source file, and you can enter another value as you need, the file size is in MB. The tool supports various video files, such as MP4, AVI, M4V, MKV, MOV, WMV and more, it can create a smaller video and help you to save disk space and network bandwidth for easy storage, transfer and sharing. This free video compressor can help you compress your video files and reduce its file size.
