Part 3. How to Reduce MP4 File Size with 3 Different Ways
In this part, we're going to introduce how to reduce MP4 file size in 3 different ways. These methods can be a little tricky but will help you achieve your goal.
Method 1: Reducing MP4 to smaller size formats
One of the simplest and most straightforward ways to reduce MP4 files is converting MP4 to a compressed video format like WMV, FLV, and others. Given below is the list of formats that you can consider for compressing MP4 files. The below table shows you the differences among these formats.
|FLV||It is a format that is suitable for web videos. You can use this format to compress MP4 files when you need to upload files to the web.||Creating an FLV format is expensive as well as time- consuming process. It takes a long time to access the web page with Flash.|
|AVI||This format is compatible with a variety of media players and is the most common compressed format that features an array of codecs.||The format is too large to compress.|
|WMV||This is a tightly compressed format that needs very less storage space as compared to MPEG-4, it has two times better compression. The format is perfect when you need to save space on a hard disk or email your videos.||The format has poor compatibility when it comes to non-windows devices and platforms like iPad, iPhone, and other Apple products.|
|MKV||It is an open-source format that features a menu for including audio tracks in a different language.||The format does not work universally across different devices and media players. It generally has a large file size of up to 40GB.|
Considering the above table of formats with its pros and cons, it can be concluded that WMV and FLV are smaller sized formats that can be regarded as for compressing MP4 files. You can make use of professional software like Wondershare UniConverter (originally Wondershare Video Converter Ultimate) or a free converter to convert MP4 to WMV, FLV, or other formats.
Method 2: Edit parameter settings with respect to frame rate, bit rate and resolution for compressing MP4 files
The next way for reducing MP4 files is by changing and editing 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 the 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 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 1080P, you can reduce it to lower resolution to reduce the file size.
- Changing frame rate: Another aspect that can be considered while reducing MP4 file size is to 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.
So if you considering changing the frame rate, bit rate, and resolution for compressing MP4 files, below listed are suggested settings of an MP4 file for Vimeo and YouTube. The file can be kept at 23.97 fps to reduce the size of the file before compressing it.
|Parameters||Compression Settings for YouTube||Compression Settings for Vimeo|
|Codec||H.264 (This offers a higher quality of video for smaller sized MP4 file)||H.264|
|Bit Rate||1000 kbps (360p), 2500 kbps (480p), 5000kbps (720p), 8000kbps (1080p), 10Mbps (1440p), 35-35kbps (2160p)||2,000 – 5,000 kbit/s (SD)/5,000 – 10,000 kbit/s (720p HD)/10,000 – 20,000 kbit/s (1080p HD)|
|Resolution||426x240(240p), 640x360 (360p), 854x480(480p), 1280x720 (720p), 1920x1080 (1080p), 2560x1440 (1440p), 3840x2160(2160P)||640 pixels wide (SD) or 1280 pixels wide(HD)|
|Frame Rate||Keep it as the original one||24, 25, or 30 FPS as the value about 20 does not make any difference.|
Method 3: Trimming and removing unwanted part for reducing video file size
Another common solution to compress the size of the MP4 file is by trimming and cutting its unwanted parts. If you have huge MP4 clips, you can do some editing by reducing unnecessary parts that will reduce the size of the file. There are plenty of editing tools as well as professional converter software available that will help you to do the task of editing and trimming.
