Part 1. Common Video Formats' File Size
First of all, let's take a look at the file size of several popular formats, which may help you choose the right format for your compression:
| Video Formats | Pros | Cons |
|---|---|---|
| MP4 | MP4 is the most commonly used and compressed video format for storing video, audio and still images. | Although MP4 uses a high degree of compression, almost all the original quality of the video are retained. |
| 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 an 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. |
As you can see, each video format has its own characteristics, and when you're going to compress videos for different occasions, you can choose the best format for your use. There's no doubt that reducing MP4 file size is the most common method used in our daily life, but when you want to compress videos for specific purposes, you may choose the right format.
Common Occasions We Need to Reduce MP4 File Size
Besides the lack of storage space on the hard disc and mobile phones, there are other reasons as well when you need to compress the size of your MP4 file, such as:
- Sending videos via email - large MP4 files cannot be sent via email attachment. Therefore you'll need to reduce the size of your MP4 file and then send it.
- Uploading to YouTube - YouTube has become the most popular video sharing site all over the world, and it allows you to upload your video to the platform with ease. But a large video will cost you a large amount of traffic, so you can compress the video file size to make it easier to be uploaded.
- Playback on Mobile - If you are using a small screen device or a limited-storage tablet, compressing your video file size will help you save the storage of your device.

Part 3. How to Reduce MP4 File Size with Advanced Settings
Video and audio files have their own codecs, which make them different from other files in size. When we want to reduce MP4 file size, we can also change the codecs of the MP4 file to make the file smaller. Speaking of changing the codecs, we're mainly talk about changing bit rate, resolution or frame rate of the video file. Therefore, if you want to reduce MP4 file size, you can also achieve the goal by changing the codecs of the video file.
- 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 a 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 | (This offers a higher quality of video for smaller sized MP4 file) | |
| 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. |
Part 4. Reducing MP4 File Size by Trimming and Cropping Unwanted Part of Video
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.
How to Reduce MP4 File Size by Trimming and Cropping
