It's extremely important to note that Apple tends to favor H265 over H264. Nowadays, nearly any device capable of playing back 1080p content supports H264. If you ever watch movies on your phone through Netflix, chances are that you are using H264. Also, each additional layer adds extra pressure onto the CPU. Because H264 is designed specifically for small screens, it doesn't support things like fast motion effects. H264 is a highly efficient way of encoding video, especially for smaller devices. There are tons of different ones out there, but H264/AVC is probably the most common one today. They convert analog signals into binary code that computers understand. Codecs refer to types of software that encode and decode digital media. And remember, lower resolutions typically lead to larger file sizes.Īnother reason your MP4 gets bigger is due to codecs. You should always use lossy compression methods like MPEG2 (which saves up to 90 percent less data). A good rule of thumb is to keep both image resolution and frame rate low whenever possible. Nowadays, almost everyone uses 1080p HD (high definition) cameras which produce massive amounts of data. In fact, depending on the situation, it might actually increase quality. So while you may think that compressing a video reduces overall quality, that isn't necessarily true. This means that every time someone watches the video, their computer must load all of that information instead of just relying on your internet connection. When you record a movie using higher-than-necessary resolutions, frame rates, or bitrates, those settings are saved into the actual file itself. Does compressing a video file reduce quality? If you're not sure where to start reducing MP4 sizes, take a look at our guide below. For example, if you've recorded high-quality footage from a DSLR camera, then these settings will consume more disk space than necessary. Your MP4 might be getting too bulky because of its resolution, frame rate, or bitrate. So let's get started by taking a closer look at why MP4 becomes so big. We're here to help explain everything about this versatile format so you know exactly how to shrink down your MP4s without compromising quality-and we'll even show you some great tools to use right now. But what if you want to upload or share it online but don't have enough space? That could mean losing views or subscribers!Įven though MP4 has been around since 2004, there are still many people who aren't familiar with how they work. It's also used in web browsers such as Chrome, Firefox, Safari and Opera to save videos. MP4 is one of the most popular formats on YouTube. How can I make a video smaller without losing quality free?.
