11/17/2023 0 Comments Compress video files online![]() ![]() 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. 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. Just read and follow.Yes, there are several advanced methods to reduce the size of a video. ![]() The next part offers a top-rated 4GB video compressor that can make your large video compression process a lot easier. But to do this, you'll need a proper video size compressor to help you. You can pick one of these methods or use them combined to shrink your 4GB video files. You can also crop or cut out the unnecessary parts from the video to reduce video size from high GBs to low MBs. So changing 60fps to 24fps, the standard frame rate for normal videos, will definitely reduce the file size. However, 60fps is more than enough for human eyes to watch videos comfortably. Compress Large 4GB Video by Frame Rate Droppingįrame rate is related to the smoothness of the video. As you change the resolution, you can decrease the video bitrate to further reduce the video file size, say, you can divide the bitrate by two if you are going to convert video from 1080p to 720p. Our powerful image compression tool that makes it easy to reduce the file size of different image files such as PNG, JPG, GIF, SVG, and more. Higher resolution usually requires a higher bitrate, hence a bigger size. Compress Large 4GB Video by Bitrate Decreasingīitrate contributes to file size greatly. Lowering the video resolution can reduce the file size significantly. Higher resolution comes at the price of a bigger file size. Compress Large 4GB Video by Resolution Downscaling Tips: The latest AV1 codec provides even higher compression than HEVC, but encoding video to AV1 will take much more resources and time. The resulting file could be even smaller if it is originally coded by older codecs like MPEG-4, MPEG-2, XviD, etc. If your source video is H.264/MPEG-4 AVC encoded, it can be reduced to half size when re-encoded through HEVC/H265. HEVC stands for high-efficiency video coding. Compress Large 4GB Video by HEVC/H265 Re-encoding Generally speaking, there are four ways to make a large video smaller. As a ten-minute 4K video would require a whopping 4GB, it’s natural that you would want to compress such large 4GB video files to save space.
