Movie Studio users can compress MP4 easily, since Movie Studio offers a wide range of high-quality presets that can be used to reduce large MP4 video to a smaller size directly within the program.Below, we'll show you step-by-step how to reduce MP4 file size and compress it in Movie Studio. That being said, we'd like to mention a useful rule of thumb here: If you lower the maximum bitrate from 24000 to 6000 kbit/s and the average bitrate from 19000 to 3800 kbit/s, you'll save a lot of data volume and (for a resolution of 1280 x 720 pixels) will usually achieve satisfactory results. So the bitrate values you set depend on your video material – they're not generally applicable to all footage. Here's an example: Footage of a news announcer in front of a stationary background can be compressed without visible loss at a greater rate than a full-blown action scene where there's a lot of image movement within a short time.
Image areas with high levels of movement are compressed with a higher bitrate than static areas with little movement.
Modern video codecs such as H.265 and H.264 work using variable bitrate encoding, which analyzes the image in terms of adjustments to its contents, and compresses the image according to its content. Here, it comes down to the "average bit rate" and "maximum bit rate" in particular. If an MP4 file created using a camcorder contains more than 25 fps, it's best to lower the fps value to 25 in order to reduce MP4 file size.īasically, anyone who wants to make an MP4 file into a smaller size – for streaming it on a website, for example – should lower the resolution and frame rate of their source material to compress their MP4 video.Īdditionally, you can compress MP4 files by adjusting MP4 codec values, or more specifically video codec values, since video images are what takes up most of the space in an MP4 container. 25 frames per second is sufficient for most cases. The frame rate defines the number of images displayed per second.

Therefore, if you want to show a large full HD MP4 on your smartphone and need to compress it for this purpose, it makes sense to reduce its resolution. Full HD resolution, for instance, contains 1920 x 1080 pixels, while Ultra HD has 3840 x 2160 pixels. If you want to display the video on a large HD monitor, you need a higher resolution than the resolution required for a smaller smartphone display.
The resolution determines the size of the image: it sets the number of pixels that will be displayed.To do this, you first need to consider the two basic parameters of resolution and frame rate. To compress an MP4 means to reduce the file size of an existing MP4 file. This factor sets MP4 apart from other formats and has made MP4 the most important and commonly used file format for video. However, modern MP4 codecs can hold this loss of quality in check. MPEG-2) can also be used for MP4 files too.Ĭompressing MP4 video to smaller size is usually associated with a reduction in quality, since this is the only way to create video files that are small enough. The most important codecs for MP4 are H.265 or its predecessor H.264 for video data as well as AAC (for audio data). MP4 is a file container for digital video that lets you compress video data using codecs.
