Solution 2: Change the Video Bitrate/Frame Rate/Resolution for Compressing MP4 Files

Different video parameters like frame rate, resolution, etc. also influence video size. So another way to reduce MP4 file size is to change and edit the parameter settings.

Changing Bit Rate: The size of the video file can be decreased by lowering its bitrate. Bit rate size is directly proportional to file size and thus reducing one will reduce the other as well. But here it needs to be understood that too much lowering of the bit rate will reduce the quality as well. Thus reducing bit rate by 20-30% of the original size is a good choice.

Changing the resolution of the file: The resolution of any file determines its size as well as quality. A high-resolution file will have good quality and a larger file size. Thus, if you are aiming to reduce file size, reducing the resolution with a video resolution reducer will do the trick. If you have HD videos with a high resolution of 1920 * 1080P, you can reduce it to 1280 X 720P, 640 X 480, 640 X 360 and other resolutions so as to reduce MP4 size. The most commonly and recommended resolution is 640 X 480 as it is compatible with the majority of the mobile devices ( Android, iPhone, and iPad) and various popular sites including Facebook, Vimeo, and YouTube.

Changing frame rate: Another aspect which can be considered while reducing MP4 file size is reduce the frame rate of the file. The frame rate is directly related to file size and thus reducing one will directly affect the other. The smaller the frame rate of the video is, the smaller its file size will be.

If you're considering changing frame rate, bit rate and resolution for compressing MP4 files, below listed are suggested settings of MP4 file for Vimeo and YouTube. The file can be kept at 23.97 fps in order to reduce the size of the file before compressing it.
