![]() ![]() The cat command (also available for Windows) is supposed to work similarly to the Windows copy command. Under the “Output” tab go to the option called “Split MPEG files every (MB):” and raise the value above the size of your output video then press “OK”.ĬLI (Command Line Interface) Methods: Cat Command: To change the setting go to the menu bar and select “Edit” -> “Preferences”. This is problematic if your goal is a single video file. Note: Avidemux has a setting that splits MPEG files when they reach a certain size. Be sure to put the extension at the end of the filename (.mpg/.mpeg/.m2v) as Avidemux will not do this automatically. A dialog will pop up and ask you where you want to save your video. The Matroska (.mkv) container should hold MPEG-2 data without any problems as well.įinally press the save button (or go to “File” -> “Save”). If you are creating an MPEG-2 file for use on a DVD you will probably want to use the MPEG PS format. Finally, at the bottom left corner, choose the container that you would like to use. Otherwise the video and/or audio will be re-encoded. idx/.idx2 file that was created first.Īfter you have added all the files that you want go to the left side of the application window and make sure that under both Video Output and Audio Output “Copy” is selected. If you chose to append the files all at once but want to go back and redo it you will need to delete or rename the. So my recommendation is to add each file independently, though it is more tedious. However, this often cause audio sync issues on my system. video001.mpg, video002.mpg, video003.mpg, …) and was located in the same directory. Older versions had an option to automatically append all filenames that followed a numbered sequence (e.g. If the two MPEGs are not compatible with each other the appending will mostly likely fail. This will append another file at the end of the previous. Next go to the menu bar and select “File” -> “Append”. Older versions have an option in the preferences menu that allow it to be disabled while newer versions seem to have omitted it, making indexing mandatory. It does a good job of joining MPEG-2 videos as long as indexing is enabled. It is free open source software and released under the GNU General Public License (GPL). It supports almost any video and audio type (not perfectly unfortunately) and is built on top of the FFmpeg libraries. GUI (Graphical User Interface) Methods: Avidemux:Īvidemux is a versatile in-line video editor and its primary functions are joining, muxing, and encoding. Codec, bitrate, frequency, and channel count should all be taken into account. A few common color spaces are RGB, YUV4:4:4, YUV4:2:2, and YUV4:2:0.Īudio Format and Encoding: The audio will be a factor as well. Some codecs support many different color spaces while others only a few or maybe even one. I didn’t realize until recently just how many different color spaces are available for video encoding. Pixel Format / Color Space: This one has been a real pain for me. If the trailing videos do not use the same it will likely result in them looking “stretched” or “squeezed”.īitrate: Videos using different bitrates may end up corrupted. ![]() Resolution: All video files must have the same width and height.Īspect Ratio: Most programs will use the aspect ratio of the initial video unless otherwise specified. It may be possible to change the framerate of all files without re-encoding with some programs. Scan Type: Progressive, top frame first interlacement, and bottom frame first interlacement are not compatible with each other and will guarantee frame corruption.įramerate: The speed at which frames are displayed during playback must match. Some things that will cause video incompatibility: Because the video is not being re-encoded the result will be corrupted or joining will fail altogether. Important Note: All files being joined must have been encoded using the same method. Each video type is different and not every method works well for them. In this tutorial I will demonstrate some of the different free/open source software methods that I prefer to use when joining various video types. Two of the most common issues that I have faced with joining video is audio sync and frame corruption problems. It is preferable to use this method when re-encoding is not necessary as it is much faster and there is no quality/data loss. In dealing with digital video, concatenating or joining generally refers to taking multiple files and placing them together sequentially in a single container (e.g.avi. *!!!* This tutorial is a work in progress *!!!* ![]()
