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 *!!!*
