Part 4. Other useful tips while reducing the file size

While compressing and reducing the videos it is important to ensure that there is no or minimum quality loss. Besides using the right tool, there are several other ways through which you can ensure that the file reduction process happens quickly, easily, and in good quality.


Selecting the right format for your file is one of the important factors to be considered while reducing the video file size. A lot of formats store the video in large size and must be avoided. Choosing lossy formats like MP4, and others will not only help to reduce the file size but also make the format compatible with multiple players and devices.


Cutting and trimming the not necessary parts of the video is another way by which you can not only further reduce the file size but also make the compression task quick. If your videos have parts that are of no use, you can trim and cut them before reducing the file as it will save time, effort and also will make the video even shorter.
