If you do not change the settings, the video will remain in its original quality and only the picture and sound codecs will be optimized to achieve the best possible result in terms of quality and the smallest possible file size. h265, so that with newer codecs, significantly smaller files can be achieved while maintaining the same quality.į has already made the best possible assumptions for resolution, framerate and codec in the default settings. In recent years, great progress has been made in this area with codecs such as. The better a codec can compress the video, the smaller the file size. The codec is also very important for the final file size of a video. How does the codec / file format influence the video size?
In the concrete example, a video with 60 fps (frames per second) results in a file size twice as high as a video with 30 fps. The frame rate h as a linear effect on the file size of a video. How does the frame rate (frames per second) influence the size of a video? This means that a video with 4k resolution (3840×2160 pixels) with Full-HD resolution (1920×1080 pixels) takes up approximately four times the file size – because the number of pixels (the product of the resolution) is also four times as high. The resolution has a quadratic effect on the size of a video. The individual aspects are explained in detail below: How does the resolution of a video influence the file size? For example, a video can contain sound for stereo (two channels) or surround sound (4 or more channels) – or even both. the sound of a video) is mainly influenced by the bit rate, the codec and the number of channels. These two aspects mainly concern the video part of a movie. The most decisive factors in the compression of a video are the resolution and the so-called codec. webm.ĭifferent technologies are used to compress a video. Which video formats can be reduced in size?Ĭurrently, supports the resizing of a variety of video formats, including the following.

You will then find the file in your download folder. The download starts automatically on the next page as soon as the conversion is completed.Upload your video file with the button “Select file”.With you can compress your video in only three steps: How can I shrink videos online? To choose this option, choose "Re-size video" from "Advanced Settings" above.If you want to send a video or embed it on your website, it may be necessary to reduce the size of a large video file.

For example, if you have a 4K (4320p) video but your target device is 1080p, you can downsize the video to fit 1080p and save file size. 4: Make Video Size Smaller (Re-Size)Ĭhoosing a smaller video resolution (dimensions) can also save file size. For more info: read video bitrate control. You can make the output file size smaller and change the resolution and quality. To choose this option, select "By Max Bitrate" from the "Video Compress" dropdown. Free online MP4 compressor tool that compresses MP4 file size. Select this method if you are using the video in a streaming application where you want to control the streaming bandwidth rate. The quality is set by CRF (constant rate factor). This method allows you to set the max bitrate for given video quality. This is the default video compression method used. Increase the target size if you need better quality. To overcome this, start with a decent size (as a percentage of original), then test for video quality. The downside is you don’t know how the target size will affect video quality. The pros of this method are, you can achieve a certain target size. For example, if you set it to 60% for a 1Gb file, we will attempt to make your compressed file size 600Mb or less. This method allows you to set a target file size for your video as a percentage of the original size. As a Percentage of the Original Size (Default) If you prefer a lower file size over encoding time, choose a slower preset. Choosing a slower preset allows better optimization (lower bitrate/file size) for a given video quality level.

You can choose it from your device: Windows, Mac, Android or iPhone. Preset: Presets refers to the video compression speed. First of all, upload an MP4 file you want to compress. Higher values mean more compression (reduced file size), lower values mean better quality (but bigger file size). For the H264 encoder, possible CRF values range from 0 to 51. Our online compressor is completely free to use and has no limit on the number of uploaded files. To do that, it uses different compression levels on different frames. By Video QualityĬRF (Constant Rate Factor): CRF method attempts to keep a constant perceived video quality. We provide 4 settings related to both methods. You can either optimize the bitrate or resize the video to a smaller size. There are two main methods to compress a video.
