• Reduce the Bitrate: The bitrate determines the amount of data used to encode the video. Lowering the bitrate will result in a smaller file size, but it can also reduce the video quality.
• Adjust the Frame Rate: Reducing the frame rate can also decrease the file size. However, lowering the frame rate too much can make the video appear choppy.
• Use Efficient Codecs: The H.264 codec is a popular choice for MP4 files because it offers a good balance of quality and compression. Using this codec can help reduce file size without sacrificing too much quality.
• Trim Unnecessary Content: If the video contains unnecessary content, such as long intros or outros, trim it to reduce the file size.
• Convert Audio Separately: If the video has high-quality audio, consider converting the audio separately and using a lower bitrate for the audio track.

By applying these techniques, you can effectively reduce the file size of your MP4 videos while maintaining an acceptable level of quality.
