Video Compressor

Technically speaking, a video file size is largely related to video length, frame rate, bitrate, resolution and encoding settings.

Basically, there are 2 simple ways to make your video smaller with high visual quality.
1. Cut short the large video.
2. Utilize a handy online HD video compressor, with which you can smartly setting compression parameters or apply its best default settings, to get the video minimized with original quality.

Step 3: Download the compressed video locally to send email or save to Dropbox/Google Drive and directly copy the link as attachment in Email.

Yes, there are several advanced methods to reduce the size of a video. Here are a few notable techniques:
1. High-Efficiency Video Coding (HEVC): The video compression standard HEVC or H.265 provides considerable enhancements. over its predecessor, H.264. HEVC achieves higher compression ratios while maintaining similar video quality. It achieves this using more advanced encoding techniques, such as larger block sizes, more efficient motion compensation, and enhanced entropy coding.
2. 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 analyzes the statistical properties of the video data and assigns shorter codes to frequently occurring patterns and more extended principles to less common ones. By adapting the encoding based on the context, CABAC achieves more efficient compression than more straightforward entropy coding methods.
3. Motion Estimation and Compensation: Video compression often takes advantage of temporal redundancy, which refers to similarities between consecutive frames. Motion estimation and compensation techniques identify the motion vectors between frames and encode the differences instead of storing complete frames. By representing the motion information efficiently, these techniques reduce the required quantity of data to represent the video sequence.
These are just a few examples of advanced video compression methods. 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.
