![]() ![]() This smaller file size can be especially useful for archiving large video files or for distributing them over the internet, as it takes up less storage space and can be sent or downloaded faster.Īnother benefit of having a smaller file size is that it can be more manageable for the user, it takes less time for processing and copying, it is easier to backup, and it can be more compatible with devices that have limited storage capacity, such as smartphones, tablets, or older media players.įurthermore, the smaller file size can also make it more efficient to stream the video over the internet, as it requires less bandwidth to play. Remuxing can lead to a reduction in file size as only the main video and one of the original soundtracks are preserved in their original form, while all other data, such as additional audio tracks, subtitles, or chapters, can be removed.Īdditionally, the new container format might be more efficient at storing the video and audio data, further reducing the file size. Remuxing can result in a smaller file size for a few reasons. There are several advantages to remuxing a video file, some of the most notable include: Smaller File Size The resulting file will have the same video and audio quality as the original, but it will be in a different container format, depending on user preference or compatibility requirements. Then, those streams are placed into a new container using the same tool or a similar one. First, the video and audio streams are extracted from the original container using a tool such as FFmpeg. The process of remuxing is relatively simple. The most common container formats are MP4, MKV, AVI, and MOV, each of them can contain different codecs, but remuxing will extract the stream and put it into a new container without changing anything else. Remuxing allows for a smaller file size without sacrificing quality, making it ideal for archiving or distributing large video files.Ī container file, also known as a wrapper or a file format, is a type of metadata that contains various types of data, like video, audio, and subtitles tracks, that are encoded with a codec. The main difference between a remux and a re-encode is that a remux only changes the container format, while a re-encode compresses the video and audio streams, which can result in a loss of quality. The video and audio in the new container will be identical to that in the original file, but in a different container format. If your screen is largely static, or if you use a lower output resolution, you can opt for a lower bitrate to save space on your hard drive.Remuxing is the process of transferring the video and audio streams from one container file to another container without any alteration to the streams’ quality. If you have a lot of fast moving objects or fast changing colors to record, you might want to choose a higher bitrate. In our example of a basic 1920x1080 screen recording, 8000Kbps usually gives a good balance between video quality and file size. Check the Video Codecs page for more info on choosing your bitrate. ![]() The downside is a potentially larger file size. ![]() CBR is best in most cases, because it ensures the video can be recorded and played back at a consistent bitrate, making it less likely to cause performance drops. See below how to automatically convert the file to MP4 after your recording, which is typically the format you want to use if you want to edit the video later. We recommend using MKV, because this format allows you to recover the video in case of a crash. Select your default folder for saving the recordings to under "Recording Path".Next, go to the "Output" tab and then the "Recording" sub-tab. Typical resolution settings for recording on a Full HD monitor.
